Hydraulic wood splitter assembly drawings. DIY hydraulic wood splitter. How to make a wood splitter with your own hands: drawings, photos, instructions of various types

Despite the active development of the energy industry, firewood is still a popular type of fuel.

Summer residents and residents of remote villages cannot do without them. The reason for this is understandable, since the construction of a gas pipeline is a very expensive undertaking. Where forest resources are plentiful, it is easier and cheaper to use firewood than to dream about the distant prospect of gasification.

If you can’t get rid of woodfuel in the coming years, then you should think about how to make it easier to harvest it.

After all, bringing a car of firewood to the site is half the battle. They still need to be stabbed, and this occupation requires not only physical strength and skill, but also endurance.

You won’t have to swing an ax in the sweat of your brow if a hydraulic wood splitter appears on the farm – reliable and productive mechanism. The principle of its operation is simple and consists in using the energy of a compressed liquid to split firewood.

By placing a log between the knife and the piston of the hydraulic cylinder, we quickly get desired result. A powerful hydraulic force splits a block of any thickness, so harvesting firewood from a laborious and unsafe occupation turns into a pleasure.

Types of hydraulic wood splitters

Let us consider in more detail the structure of these mechanisms in order to understand the principle of their operation and choose the appropriate option for ourselves.

According to the number of operations performed, all are divided into household and professional. The former only split firewood, while the latter are equipped with additional devices for feeding, trimming and unloading them.

Depending on the position of the split log, hydraulic wood splitters are divided into three types:

Horizontal. The log is laid on a horizontal chute. There are two schemes for the operation of such devices. In the first case, the knife is fixed on the frame, and the pusher moves a piece of log towards it. In the second version, the log stands motionless on the stop, and the hydraulic drive feeds the knife to it.
Vertical. The log stands upright, and the knife is fed from above and splits it. The advantage of this scheme is higher performance and compactness of the installation. The disadvantage is the need to hold the log with your hands, which increases the risk of injury.
Mixed. Such mechanisms can work in both vertical and horizontal modes. Used in the industrial woodworking industry.

Another distinguishing feature of hydraulic wood splitters is the type of engine.

The household hydraulic cleaver is equipped with an electric motor that rotates the hydraulic pump. This drive has three important advantages: reliability, ease of maintenance and environmental friendliness. The disadvantage is the rigid dependence on the power supply network.

More powerful mobile wood splitters are equipped with gasoline or diesel engines. They are used by professional lumberjacks.

For forestry, farmers and commercial enterprises, mobile models have been created that operate from the hydraulic system of the tractor or from its power take-off shaft.

There are universal mechanisms that can operate from an electric motor and tractor drive or from a gasoline engine and tractor hydraulics.

The price of a household hydraulic wood splitter, depending on the brand, engine power and frame design, ranges from 9,000 to 32,000 rubles. Powerful models designed for chopping firewood in large volumes cost much more than 70,000 - 120,000 rubles or more.

Do-it-yourself wood splitter - quite real!

The simplest hydraulic splitter- a vertical frame on a platform, in the lower part of which a conventional car jack is installed. The upper crossbar of the frame is detachable, which allows you to chop firewood of different lengths on it.

Instead of a flat knife, a conical wedge is used here. It is brought close to the log with the help of a central screw, after which they begin to work with a jack. His heel presses on the chock from below, the wedge enters it and splits along the entire length.

A more complex design of a homemade household wood splitter comprises hydraulic jack installed on a stationary or mobile frame.

At the other end of the bed there is a wedge knife (6), which has several positions for chopping firewood of different lengths. In the middle part of the machine, a bed (2) is installed for stacking logs. Due to the reciprocating movements of the jack handle (12), the rod with its thrust heel (8) presses on the log, which splits on the wedge knife. The return of the rod to its original position is performed by two springs after the oil pressure in the hydraulic cylinder has been relieved by the handle (11).

The disadvantage of the two considered mechanisms is obvious - the low speed of chopping firewood. To complete one work cycle, you will need to make at least ten movements with the jack handle. If the volume of harvested fuel is calculated in cubic meters, then work on such homemade machine will take a lot of time.

You can increase the productivity of a manual hydraulic cleaver by making the wedge knife cruciform. In this case, the chock will immediately be pricked into four parts, and not into two. In any case, get homemade device it will be useful for your household, since it is not always possible to split thick logs with an ax, as well as chocks with intertwined layers of wood.

In order for a homemade hydraulic wood splitter to work more productively, you will need an electric motor, a hydraulic cylinder with a pusher, an oil reservoir, a pump and a control unit.

Such a machine works faster than a mechanism with a manual jack. Here, the working cycle and the return stroke of the piston do not require manual effort. By pressing a button on the control unit (CU), you give a command to the distribution mechanism to pump oil into the left or right cavity of the hydraulic cylinder.

As a result, the thrust heel of the rod moves in the right direction. The time required to split the log and return the rod to its original position for such a machine is no more than 12-15 seconds.

Wood splitter hydraulic or wood splitter - a means of automating the preparation of firewood. Most often, a hydraulic splitter is called a "mechanical splitter". Moreover, many models were created by the hands of home craftsmen and qualified engineers.

Application and working principle

Mechanical and hydraulic are used in private households, or in small woodworking workshops. In any place, the machines perform mechanical cross-cutting, as well as splitting wood of various species.

A hand tool for splitting and bucking breaks very often, and it requires skill, effort and time. Machines and installations of a different, non-hydraulic type very often break down due to uneven loading.

Wood splitters factory

The construction equipment market offers several dozen models of hydraulic wood splitters in the price range from 10 to 200 thousand rubles. It is important to know that the price depends on:

weight;
power;
efforts;
engine type;
maximum for log length;
voltage (models with electric motor).

Power supplies for the engine are divided into 2 categories.

Electric motor. This energy converter acts on the pump. Moreover, the electric motor is used in the most primitive, household machines. It is very easy to maintain such models, and you can use them in the same garage or shed, given environmental safety. Assembled by hand or in the workshop, models with electric motors are the easiest to prepare for work, it is even allowed to be carried by hand. The main disadvantage is that they do not function without power supply.

Gas engine. It is installed on powerful models that can be transported to the place of firewood harvesting. A gasoline fired wood splitter is usually heavier, more expensive and more powerful. But it is also more functional due to mobility and greater power.

Homemade wood splitters

Most often used for domestic needs in preparation for the heating season. Moreover, the level of engineering thought of a rural worker can inspire the creation of household and professional equipment.

In this case, everything is clear with the household one, but the professional machine can work in line. Simply put, still have the function of feeding, trimming, unloading.

Anyone wishing to independently create similar installations to facilitate labor can familiarize themselves with drawings, diagrams and video instructions online. An example of a good self-assembled hydraulic wood splitter is this video:

What is included in the design of a hydraulic wood splitter?

A do-it-yourself hydraulic wood splitter must consist of certain parts. It is better to make parts according to their importance, and start from:

beds;
cylinder stop;
wedge-shaped blade (or blades);
pump;
liquid pressure distributor;
oil tank;
engine or motor.

How are they hand-picked?

The easiest way to assemble a working log splitter starts with welding a frame that needs to be fixed to the platform. Bottom part platform is equipped with a car jack (at least).

At the top of the frame, a connector must be calculated. It is needed for splitting chocks of different diameters and different lengths.

The wood splitter in the photo was created by hand, but it is already designed for an industrial volume. It has a more complex design, which necessarily consists of a hydraulic jack on a stationary (non-portable) type bed. The creation of this installation requires a locksmith skill, safety calculation. Let, at first glance, the unit is not complicated, but the work of the operator with a negligent attitude will sooner or later lead to an accident.

Due to saving time and resource, wedge-shaped knives with 4-8 blades were created. The fact is that a standard knife divides a chock into 2 parts, and this model processes any log in one go.

A do-it-yourself hydraulic wood splitter at increased power (driven by a tractor, gasoline engine) should be equipped with a wedge-shaped knife with 4 blades, at least.

Many for suburban buildings operate on wood. In the 19th century, wood cutting was carried out manually, but with the creation of mechanical wood splitters, human work was noticeably facilitated. The very first devices were steam, and they could not be built at home. Currently, you can assemble a wood splitter with your own hands. Drawings, photos, instructions will help to do this without any problems.

Such a device allows you to cope even with large logs and logs.

How to choose a wood splitter: product features

If a wood splitter is needed on the farm, then it is important to decide whether to buy ready product or assemble it by hand. When implementing the latter option, certain skills will be required. For example, you can study the catalog of components for screw and cone wood splitters of any manufacturer and assemble a reliable and productive unit on your own.

Other equipment options work on the principle that the motor moves special knives onto the log, when pressure is applied to which the log splits. To create a quality product, you should study the information on how to make a wood splitter with your own hands and what type of device is better to choose.

There are a lot of installations working on this principle and they differ from each other in certain ways:

according to the method of laying logs. There are vertical and horizontal mechanisms. Vertical type devices are considered more powerful and can work with thick logs, but for a crooked log, you should choose a horizontal device;
maximum possible values stacked firewood. Depending on this factor, the equipment is divided into industrial and household;
drive types. For domestic use, it is enough to use an electric unit with a power of about 2.5 kW.

In addition, the weight of the household tool matters. Such a product can be designed independently.

Wood splitter classification

To deal with the drawings, photos and instructions created by yourself, you should know what types of these devices are.

Wood splitters are classified according to the type of drive:

simple option for petrol or diesel fuel, which is characterized by autonomy and high efficiency;
for small volumes, mechanical type devices are recommended;
stationary options include models that operate on electricity.

By design features and the splitting principle, the wood splitter is of the following types:

electric wood splitter with a vertical log;

rack type device;

screw is very powerful;

hydraulic.

For use in everyday life, you should choose hydraulic and screw versions of the wood splitter with your own hands. The video shows how to make such products yourself.

Characteristics of models with a cone-shaped cleaver

In electric and diesel devices, a cleaver in the form of a cone is used, which splits the trunk with the help of mechanical pressure and due to the movement of the tip of the cleaver. At the same time, great effort is not expended and fuel consumption is minimal.

The apparatus consists of the following parts:

a motor with a power of 1.5 kW, a number of revolutions of about 400 and a voltage of not more than 380;
the frame is a desktop surface where firewood is stacked;
the gearbox is used to control the speed.

If you decide to make such a wood splitter with your own hands, then drawings, photos, instructions for it will be easy to find on the pages of the interior, and all components can be found at an affordable price. Similar devices are used for small, and.

Features of hydraulic wood splitter

With the help of the hydraulic model, a significant amount of raw materials can be processed in the shortest possible time. The operation of the device is carried out by the engine and hydraulic equipment.

When assembling such a model, it is worth considering some features:

the location of the logs vertically or horizontally;
allowable sizes;
cylinder dimensions and motor features that affect the power of splitting raw materials;
motor power.

It is more difficult to build such an assembly than a screw product. This device has a higher productivity, it can be used not only for domestic purposes, but also for commercial ones.

The nuances of the rack option

In the rack device, the cleaver is fixed to the rail, which moves with the help of a gear. The log is installed between the thrust device and the cleaver. The log is split by pressing on a special handle of the equipment. After that, the gears are firmly engaged, and the rack with the cleaver moves forward to the log.

The reverse movement shifts the cleaver to its original position, and the split log is removed. Such a device operates from an electric motor and does not require complex maintenance.

For the rack unit, the following parameters are considered important:

possible length of the canvas;
kind of cleaver;
force applied to the workpiece.

Do-it-yourself hydraulic wood splitter installation features: simple instructions, drawings and photos

Assembling a hydraulic model is difficult due to the mechanism. You will need to find an oil tank, a special cylinder, a fluid flow control unit, and.

First of all, the frame is made. It is better to mount it on wheels or chassis in order to move the device in Right place. The main hydraulic part is attached to the frame. Instead of a knife, a conical wedge is adapted, which is moved to the log with the help of a central screw.

Higher productivity is characterized by cleavers with engines. Their installation requires a hydraulic cylinder, an oil tank, a control unit and an electric motor. Such a device works faster than a mechanism with a jack. This requires less effort.

A command is sent using the control button switchgear to supply fluid to the cylinder cavity. As a result, the thrust heel moves in the desired direction.

This design does not have a high speed of operation, but it has a certain convenience.

Useful information! Most often, the hydraulic installation is taken from the tractor. A gasoline-powered engine is also used.

How to build a model of a screw wood splitter with your own hands: drawings

The easiest way is to assemble the screw assembly yourself. To do this, you need to buy a screw cone for a wood splitter. You will also need a powerful, strong frame, reduction gear and shaft.

First of all, the engine and gearbox are mounted to the frame. A cone is attached to the shaft, and the mechanism itself is connected to a reduction gear using a motor. When assembling, important points to consider:

the nozzle cannot be directly mounted to the motor;
If you don't have electrical skills electrical mechanisms must be done by a highly qualified specialist;
belt and chain drives are protected by a special casing;
the minimum rotation speed of the cleaver is 250-300 rpm.

A similar type of wood splitter works with a rotating metal cone that splits logs due to a special thread. When assembling a screw model with a cone-shaped splitter, it is necessary to choose the right cone depending on the logs used. The base for the device has the form of a working platform with a fixed cleaver shaft. A keel is welded to the table to avoid particles getting under the rotating mechanism. Power supports are mounted, and the cleaver is installed in the working position. Then the engine is connected.

A popular wood splitter model with an engine from. Three types of motors can be used: asynchronous, commutator or electronically controlled. The most common option is asynchronous motors. Older models have a separate winding for starting.

Many owners of private houses heated by stoves and solid fuel boilers, wood splitters are used to harvest firewood for the winter. Not everyone can purchase industrial units because of their high cost. To make a wood splitter with your own hands, it is enough to have its scheme on hand and follow the sequence of work performed.

What it is

Equipment designed to split a piece of wood into logs is called a wood splitter.

For professional harvesting in industrial volumes, wood splitters are produced. These complexes are capable of trimming a log into blanks of the required length and chopping them into logs. Finished products from working area removed by the conveyor.

Wood splitters are used at sawmills to split logs into logs of the required size.

A household wood splitter is intended only for splitting chocks into logs, but the log must first be sawn into blanks. The performance and operating time of this equipment is limited. With the help of household wood splitters in the private sector, firewood is harvested for a bathhouse, a fireplace and for the winter.

Logs after splitting can be used as fuel for a boiler, fireplace or stove

Kinds

Devices are produced with vertical and horizontal arrangements of the workpiece. In the first version, the workpiece is placed on the frame and the cleaver is lowered from above. The advantage of vertical wood splitters is that curved chocks can be placed on the bed, but they will have to be held by hand, strictly observing safety precautions. In the second type of wood splitters, the workpiece is placed in a horizontal chute and moves to the knife. These devices are more practical and safer than vertical ones, but they take up more space.

According to the type of energy used, cleavers are divided into:

Kinetic (manual);
Mechanical.

The first type of cleavers works by using human power and does not require additional technical means. These products are the most economical and most popular because of the low cost, ease of manufacture.

Scrap Cleaver

It is a long metal rod with a pointed cone on one side and a handle on the other. The cleaver is lifted with hands and with force lowered with a cone onto a log. Productivity is low, and work requires a lot of physical effort.

The wood splitter is excellent for cutting heavy and thick softwood logs.

Cylindrical manual

Compact and easy to carry. It is used for preparation of a small amount of firewood (for a fireplace or a bath). A frame with a blade directed upwards is fixed on the stand. The blank placed inside the frame is struck with a sledgehammer. The blade divides the chock into logs.

For a private house, one of the simplest and safest options is a cylindrical manual wood splitter.

spring

The most common and productive among kinetic devices. The workpiece is split by the working part, fixed on the beam and shock-absorbing spring. Requires little effort.

Mechanical wood splitters according to the type of work are distinguished into:

hydraulic;
Cone (screw);
Rack.

In a spring wood splitter, the main force is taken by the spring

Hydraulic

The advantages are smooth running and creating a large load on the workpiece.

Despite the creation of a large force of the working stroke, the hydraulic wood splitter does not have a high speed of work

Energy from an electric or gasoline engine is transferred to a hydraulic cylinder. The working fluid enters the rod, which moves the stop with the workpiece to a permanently fixed knife. The force generated by the hydraulic cylinder can reach 10 tons. The stroke of the rod and the direction of movement are regulated by the distributor. It also protects the mechanism from breakage if its power is not enough to split the chock.

Screw

The principle of operation is based on screwing a cone-shaped working element into the workpiece and splitting it into 2 or more parts. They produce screw devices in 3 versions, with a difference in the methods of transferring energy from the engine to the working cone. The cone is fixed directly or through a flywheel on the shaft of a low-speed electric motor (up to 5 kW, 400-500 rpm).

The cone-shaped cleaver is most often used in gasoline and electric models.

From the engine, the torque is transmitted to the cone using a belt or chain drive. The pulleys are selected so that the speed of the cone does not exceed 300-400 rpm. Sometimes the motor transfers energy to the cone through a geared motor. This design is relatively complex and is mainly used in industrial wood splitters or craftsmen.

For productive work, the drive power must be at least 1.5 kW

Rack

The operation of the device is based on the method of operation of the rack and pinion. The movable transmission rack is operated by a gear mounted on a reduction belt pulley connected to the engine. Pinion and rack contact provides the control handle. The toothed rack moves along guides mounted on a reinforced frame, and on the other side of which there is a cleaver. The reverse stroke of the rail is made due to the return spring. Rack wood splitters are distinguished by reliability, economy and excellent performance.

The cleaver in the design of the rack wood splitter is attached to the rail, which moves due to the gear

According to the type of traction, wood splitters can be divided into:

Electrical. Power is supplied by an electric motor. These devices are low maintenance and easy to use. Installation indoors is possible. The downside is low mobility due to attachment to a source of electricity
Wood splitters with a gasoline engine have more power and productivity. They are used both in everyday life and in industrial preparations.
Tractor-drawn wood splitters. The working cylinder of the device is connected to the hydraulic system of the transport, which significantly increases the speed and working life of the wood splitter. These models are used when it is necessary to prepare a large amount of firewood in forestry or on a farm.
Combined traction. It is used on industrial wood splitters and can be of two types: tractor hydraulic drive and electric motor, tractor hydraulic drive and gasoline engine.

To solve everyday problems, manual and electric wood splitters are most often used, less often - gasoline.

Factory models are much more efficient and have a presentable appearance.

Before buying or manufacturing any wood splitter, you need to pay attention to the following technical characteristics:

The splitting power of the hydraulic device should be within 3-7 tons.
The acceptable speed of rotation of the working cone of the screw wood splitter is 400-600 rpm.
The working length (distance between the piston and the knife) indicates the maximum longitudinal dimension of the workpiece to be split. In household wood splitters it is 0.5-0.6 m, in industrial - 0.5-1 m.
The presence of a piston stroke limiter increases productivity and saves resources when processing short workpieces.
The optimal piston speed when moving forward (working) is 4 cm / s, backward - 7.5 cm / s.
The engine power in hydraulic wood splitters is 1500-2300 W, in screw - 3000-4000 W.
Dimensions and portability of the device.

Making a wood splitter with your own hands

The purchase of a factory wood splitter is not always economically justified, especially since some types of this mechanism can be assembled with your own hands from simple materials.

spring

To create it, you will need the following material:

Channel;
I-beam;
Pipes or corner for the frame and stiffeners;
Metal corner;
Square tube;
Automotive spring;
A piece of pipe with a diameter slightly smaller than that of a spring;
Hinge assembly;
Cleaver;
Weighting agent (piece of rail or channel with a thick shelf).

For a stationary wood splitter, you can pour a concrete base by inserting a rack into it. In this embodiment, it is not necessary to make a frame. All parts of the wood splitter, except for the hinge, are connected by electric welding. Cut off pieces of the channel for the bed and the I-beam for the base. The length of the support is 0.6-1 m. The height of the base is selected individually. The support is connected to the frame, strictly maintaining an angle of 90 o. For structural stability, pipes are welded horizontally to the ends of the frame. The connection of the bed and the base is reinforced with spacers.

To increase the stability of the structure, it is necessary to install spacers

A piece of a channel 40-50 cm long serves as a platform for the spring. On one side of it, a hole is cut out with a grinder for connection to the base. A spring guide is welded to the other edge. To determine the place of attachment of the platform, it is necessary to subtract the length of the spring from the height of the support. The platform also needs to be reinforced with spacers from the corner.

In order to determine the place of attachment of the platform, it is necessary to subtract the length of the spring from the height of the support

In the upper part of the base, a seat 8-10 cm deep is cut out for the outer element of the hinge assembly. Then prepare the channel for the cleaver. To do this, on one side of the channel 0.5-0.7 m long, at a distance of 10-15 cm from the edge, a rectangular hole is cut out of such a length that the base beam does not interfere with the channel put on it. In the center of the hole, the inner rod of the hinge assembly is welded. A spring seat is attached to the second edge of the channel.

The beam will move with the help of hinges

The distance from the base to the lower and upper cups for the spring should be the same.

A cleaver is welded to one side of the metal square from below at an angle of 90 °, and a weighting agent is on top. The second side is connected to the channel for the cleaver so that the total length of the resulting arm is 1-1.5 m. The resulting assembly is put on the base so that the outer elements of the hinge fall into the seat on the beam, fixing them by welding. A spring is put on the landing cups. For ease of use, a handle is attached near the cleaver.

The rail welded over the cleaver will act as a weight

To make the device mobile, 2 wheels are attached to the frame from the base side.

Tapered or screw

The main active part of this wood splitter is a threaded cone, which splits the tree, screwing into its structure like a self-tapping screw (“carrot”).

The splitter of a screw wood splitter is a cone-shaped element, also known as a "carrot"

In order to make this mechanism, you must:

According to the drawing, make a cone from a ST-45 cylinder with a diameter of 55 mm and a length of 14.5 cm at an angle of 30 o.
On a lathe, apply a thrust thread to the cylinder with a pitch of 6-7 mm and a depth of 2 mm.
The finished cone is put on the shaft and secured with a pin.
On the opposite side of the shaft, 1 or 2 bearings are mounted and a flange is welded (an asterisk for a chain or a pulley for a belt).
Supports are welded to the bearings to fix the mechanism to the table.
A spacer is placed between the shaft and the engine to tension the belt or chain.
The conical design with an electric motor using supports is fixed on a table made of dense, strong wood with metal legs.
The cone is fixed at a height of 10-15 cm from the table surface.
The engine, belt or chain is covered with a metal casing for safety reasons.

During operation, the cone slowly cuts into the log and breaks it into several pieces.

If it is problematic to make a cone on your own, then it should be purchased at a specialized store.

The direction of the thread does not matter, but when cutting a right-hand thread, there is a possibility of spoiling the cone

Video: how to make a "carrot" in the garage

Rack

First you need to decide on the drawing according to which the unit is manufactured. It is necessary to take into account the desired performance, the type of wood and the place of installation. Based on these data, the engine power and the parameters of the rack and pinion mechanism are calculated.

The basis of the rack wood splitter is a powerful steel frame, to which the drive and frame are attached

The mobile frame is made of a profile pipe and a corner. For a stationary wood splitter, the frame can be made from a heavier channel and I-beam.
When welding the frame, verticals and horizontals must be strictly observed, which will further affect performance and safety.
The design must be stable, the wheels on the frame must be securely fixed and have a fixation for the duration of the work.
The length of the rail should be 1.5 times the distance to the cleaver.
The log feed speed is selected individually and is regulated by the selection of the reducing number of pulleys.

The horizontal stacking mechanism in the form of a trough ensures optimal movement of the workpiece towards the splitter.

Hydraulic wood splitter from a jack

The simplest hydraulic wood splitter is made according to the following scheme:

A vertical frame is welded from a channel with a base for a car jack. The height of the frame depends on the length of the workpieces to be split.
In the center top bar frames install a conical wedge on a screw drive. To do this, the necessary thread is cut in the hole on the frame.
The workpiece mounted on the jack rod is first fixed from above with a wedge using a screw. Further, using a jack, the chock is strung on a wedge and split into logs.

A car jack is suitable for the manufacture of a hydraulic wood splitter

There is no universal technology for creating a hydraulic wood splitter. It all depends on the hydraulic system available, which consists of:

Hydraulic cylinder with pusher;
hydraulic pump;
Distributor of working fluid flows;
oil tank;
Electric or gasoline engine.

The frame is constructed from a metal channel, an I-beam, a corner and a profile pipe. For mobility, it is recommended to place it on a finished chassis or wheelset.

An example for the hand-made creation of this unit can be factory models or piece copies of craftsmen, whose photos and videos are published on the Internet.

Safety

To work safely with a homemade device, the following rules must be observed:

The process of harvesting wood should be carried out in closed clothing, gloves and goggles, so as not to be injured by a chip flying off the workpiece.
The workpiece must be firmly seated in the chute and not move during movement.
When the piston moves, it is forbidden to stretch your hands to the knives and correct the shifted workpiece.
Any manipulations with the workpiece are performed after the unit is turned off and all its components are completely stopped.
Work on repairing or replacing the units of the wood splitter is carried out by disconnecting the electric motor from the mains supply.

Wood splitters greatly facilitate the preparation of a large amount of firewood, saving time and effort. However, to provide firewood for a fireplace or bath, there is no need to purchase complex expensive equipment. It is much more pleasant and healthier to use an ordinary ax.
