How to use an electric chain saw • EVDIRAL.RU

It is impossible to imagine life today without power tools. They are used in production and at home, perform many tasks, make work easier and save time. Any power tool runs on electrical power and is often equipped with unsafe accessories.

An electric saw is one of the ten most popular tools. Chain, circular, and reciprocating electric saws differ in their characteristics and scope of application.

To operate any electric saw, you need certain skills, knowledge of safety regulations and mandatory compliance with them.

Electric chain saws

Unlike gasoline analogues, electric chain saws have a number of advantages: they are environmentally friendly, do not depend on the availability of fuel, are less noisy, and have less weight. Using a universal electric chain saw, you can make cuts of materials of various structures: wood, wood boards, brick, laminate, slate, metal, ceramic tiles, drywall.

On the other hand, the capabilities of chain saws may be limited by the availability of a power source, the length of the power cable, limited power and performance. In addition, electric chain saws are potentially dangerous equipment; before using an electric chain saw , each owner must carefully read the instructions and then strictly adhere to the prescribed requirements and recommendations of the manufacturer.

The cutting element in a chain saw is a closed chain mounted on a bar. Depending on the location, saws can have a longitudinal or transverse electric motor. The design with a transverse arrangement is the most appropriate: due to the absence of a gearbox, the need for its maintenance and repair is eliminated, and the saw is much lighter in weight.

How to use a reciprocating saw with different materials, different techniques

Metal - lubricating the workpiece with oil and reducing the saw stroke will help prevent excessive overheating of the blade. Special pencils are commercially available to lubricate the blade itself. In addition, when sawing, you should strictly adhere to the cutting line and do not change direction. Otherwise, the blade will simply bend, which will worsen the quality of the cut and increase vibration.

Inset - in such cases it is optimal to use new rigid short blades 10-12 cm. The electric saw is installed with a support shoe on the part, the blade is placed above the future place of the cut, but without touching. Turn on the reciprocating electric saw and start working at medium speeds, gradually changing the angle of inclination of the saw. After some time, you can feel the moment the blade comes out from the back side, after which they continue sawing along the intended lines.

Flush cutting - using bimetallic flexible blades. The electric saw is installed tightly to the wall so that the blade is placed behind the workpiece, the file is bent until the shoe hits the wall. If you need to cut a pipe a short distance from the wall, you can set the blade with the teeth facing up.

How to use a reciprocating saw

Experience is gained quite quickly, especially if you have skills in working with various electric saws. Thanks to the soft start, the saw starts working very softly and smoothly; you just need to guide its movement with light rocking movements up and down. Reciprocal movements back and forth remove sawdust.

A not entirely pleasant feature of reciprocating saws is the presence of vibrations, and even expensive models with an anti-vibration system do not provide high security. Therefore, the most reliable way to reduce harmful vibrations is to secure the workpiece as firmly as possible.

Sometimes, when the load is high, the reciprocating saw starts to work harder. In such cases, you should not apply force to the tool, this will already worsen the progress; it would be more correct to continue sawing with smooth rocking movements up and down. When purchasing a reciprocating saw, you should give preference to models that have an adjustable sole height, which will help extend the life of the tool.

Teeth and their shape

The capabilities of the saw depend on its shape and size of the teeth. A large number of teeth on a given length of blade means a fine cut but slow forward progress. A small number of teeth produces a rough cut.

Wood is made up of fibres, and when sawed they separate. This creates sawdust that needs to be removed. The finer the teeth, the faster the cut and the cutting edge of the saw become clogged with small sawdust - saw flour. The teeth can no longer grip wood to its full height. Sawing is becoming more and more tedious and, most importantly, unproductive. But large teeth almost never get clogged due to the greater distance between their tips and each other.

Almost any saw has teeth that are set apart, that is, their tips alternately deviate to the left and then to the right. The greater the angle of inclination, the wider the cut strip, and therefore it becomes less clogged with sawdust, and the saw jams less.

Over time, saw teeth become dull and need to be sharpened. In this case, the damaged wiring must be restored. Even for a specialist this is not an easy job. Therefore, we recommend purchasing saws with hardened teeth. They don't get dull as quickly, and they are easier to sharpen than the teeth of a regular saw.

You just need to put the saw blade on the table and use a sharpening stone to run it twice along the cutting edge from the end to the handle, then turn the blade over. The saw is sharpened, you can start working.

Steep teeth for rip sawing

This is how the teeth are positioned on almost all hand saws, including hacksaws and back saws.

The cutting edge of the teeth is located vertically. Suitable for longitudinal cuts.

rip sawing with a hand saw

When cutting longitudinally, the workpiece should protrude sufficiently beyond the workbench - this makes sawing easier.

The marking below the gap indicates where the saw deviates.

Reciprocating saws

Reciprocating electric saws use a thin file as a cutting blade. By design and purpose, this is an electric hacksaw that cuts through reciprocating movements. The speed of reciprocating electric saws can reach 3000-3500 strokes/min, the length of the cutting blade is 100-350 mm.

Reciprocating electric saws are used for cutting various materials; it is especially convenient to work with a reciprocating electric saw in hard-to-reach areas: hard and soft wood, aluminum, pipes, plastic, foam blocks and gas blocks, all kinds of profiles, fittings, drywall. A significant advantage of reciprocating saws is their high cutting accuracy, an order of magnitude higher than that of an electric chain saw.

When installing various attachments: files with different characteristics, abrasive attachments, metal brushes, the capabilities of the reciprocating saw are significantly expanded. Complete with additional accessories, a reciprocating electric saw can be used to grind, polish surfaces, and remove rust.

Electric hacksaw

In conditions where it is impossible to use a chain saw or circular saw due to limited space, and a jigsaw will not give the desired result, an electric hacksaw is used. It will cope well with the work of a hand hacksaw on wood, but without the need to exert excessive force, since the forward movement of the cutting blade is carried out solely by the electric motor.

The advantages of an electric hacksaw for wood include an even cut with smooth edges, which cannot be achieved with a chain saw, as well as the absence of restrictions on the thickness of the workpiece inherent in a circular saw.

Structurally, the saw consists of a drive motor with a gearbox and a cutting blade that moves along guides. An important characteristic of this type of electric saw is the length of the blade. It can reach 40 cm or more.

Types of power saws

The first option is suitable for sawing thick beams, large ridges, boards and plates.

The second type of electric saw is used for sawing beams and boards both lengthwise and crosswise. In addition, this tool is equipped with two handles for convenience. When you attach it to a workbench, you get a very convenient machine, often used in domestic production, designed for sawing boards.

But no matter which tool you choose, it’s worth knowing all the rules that you simply need to follow so as not to harm yourself or others.

Requirements upon completion of work

The last thing to know is the safety precautions to take when finishing up using the power saw.

The first thing that is necessary is to disconnect the device from the network and fold the cable.
The chain or disk must be removed and the saw cleaned of sawdust.
Wipe with kerosene and store in a specially equipped box until the next use of the power tool.
Also, if problems are detected, it is necessary to repair it or give it to a specialist.
Clean clothes from sawdust and dust, change clothes and take a shower.

Here is a small set of rules when working with an electric saw.

Tool requirements

To lay the flooring, the material must be taken 10-15% more than the area of the room. The panels will need to not only be connected, but also cut. To adjust the dimensions, use a hand or electric tool. When used at home it should:

have a compact size;
be light in weight;
be easy to use;
make an even cut without chipping.

The last characteristic is key for many repair enthusiasts when choosing a method.

But its importance is somewhat exaggerated. The presence of chips up to 5 millimeters will hide the baseboard

Both specialists and home craftsmen use:

hacksaw;
cutter;
circular saw;
jigsaw

Safety precautions when working with a saw

Electrically driven tools are now being used more and more often in everyday life, as they have become compact in size and affordable. Using power tools to make a variety of metal and wood products saves a lot of time and effort. And one of these is the electric saw . And to use it, you need to know the safety rules to avoid injury or worse.

Safety when working with a saw

The next thing to consider is the safety rules when working with a power saw, including the following:

When working with chain saw, only cross cuts are allowed; cutting longitudinally is prohibited, as this will lead to rapid heating of the chain.
It is also important to monitor the position of the power cord so that it does not get caught in the circuit.
In the event of an emergency, a special brake must be used.
When working with the tool, it is necessary to focus on the wood with special teeth.
Do not allow the chain to become pinched between layers of wood, which could lead to rupture.
It is prohibited for people to be in front of the saw blade when it is in operation.
The tool must not be passed around during operation.
If a tree is being cut down, it is necessary to make an oblique cut to a third of the diameter of the trunk from the side of the larger part of the crown, and then finish it from the opposite side.
No strangers are allowed in the work area when felling trees.
If any malfunctions occur, the tool must be immediately turned off and repaired or sent for repair.

This completes the rules for working with a saw, but it is important to know the safety precautions when working with a saw in case of emergency situations. There are not many such rules, among them are:

If the cable is damaged and there is an electric shock, the assistant must immediately turn off the power to the device, provide first aid and call an ambulance.
In the event of a circuit break or misalignment, you must immediately turn off the power to the device and use the emergency brake to avoid injury.

That's all and now let's move on to the last stage.

Preliminary preparation for working with a power saw

First of all, let's look at what you need to do before you start:

Prepare clothes. First of all, there should be no open areas on it, since twigs can fly off, which are quite dangerous when flying at high speed. At a minimum, they can get stuck in the skin, but there have been cases of getting into veins and arteries, which entailed blood loss and even death.
It is also necessary to carefully prepare the workplace. There should be no people on it, the passages should be clear, and in addition, there should be no foreign objects at all.
Before starting work, you should check whether the fastening of parts and electrical wiring is in good condition, and whether the saw blade is securely fastened.
It is also worth checking the saw cable; under no circumstances should it be damaged.
In addition, the electric saw must be grounded.
When using the tool, the voltage in the network should not be higher than permissible for operation.
Sawing boards is permitted only in a dry, ventilated area. It is forbidden to start working near water, in a damp or damp place.
It is important to keep a close eye on the saw blade or chain.
In addition, you should first check the lubrication oil level and add it if necessary.
All elements of the saw must be covered with a protective casing. Working without it is strictly prohibited.
We also note that it should be possible to turn off the saw as quickly as possible in an emergency, while it is also necessary to exclude the possibility of self-disconnecting from the network.
Check the level of sharpening of the chain or disk, since poorly sharpened teeth of the electric saw lead to its rapid and strong heating during operation.
It is also necessary to use safety glasses, and preferably a respirator or gauze bandage.

This completes the preparation rules, and now let’s move on to the next point.

How to cut trees with a chainsaw. Preparatory stage

Before you start telling us how to cut trees with a chainsaw, you should talk about preparing the tool.

Check the serviceability of gas-powered tools, especially if you decide to use a gas or electric saw after the winter break.
It may be necessary to install a longer guide bar on the tool. The latter must be at least the same size as the trunk.
Check the correctness and quality of sharpening of the saw set. It is best if you install a type of chain on your tool that is specifically designed for cutting trees.
Safety precautions must be observed. You should wear comfortable clothes that do not restrict movement, gloves on your hands, and safety glasses on your eyes.
Calculate the trajectory of the fall of a cut tree trunk. A falling barrel should cause minimal damage.
Choose the direction in which the trunk falls so that it can be easily cut in the future. If we are talking about a specimen that is large in girth, then you should think about how vehicles can approach the fallen giant, which will evacuate the sawn wood.
You may want to cut down particularly large branches before you start cutting. In the most difficult situations, industrial climbers should be called in for these purposes. It is best to use an electric saw to cut branches. This is a lightweight and compact tool that is convenient for performing precise and neat work.
Safety instructions are written for a reason. Every word of hers is written by multi-million dollar lawsuits from “grateful” users. Therefore, it is worth reading the instructions, if only to know exactly why you will not be able to file a claim with the manufacturer. After all, he already warned you that you can’t do that.

Safety precautions when using a power saw

Safety regulations must be strictly observed when working with a power saw. And dozens of conditions can be noted as mandatory. Let's divide all the rules into three parts:

Preliminary preparation for work.
Safety when using the tool.
Requirements for completion of work.

Each of these parts is undoubtedly important, and therefore we will consider all the rules of each of them in order.

Now, having familiarized yourself with all the rules for using an electric saw, you can safely work with it. But remember that following safety precautions is the most important thing that can protect you from many problems during work, which can often result in injuries. In conclusion, we offer several videos on how to use an electric saw.

Rule

Operating a power saw does not require special knowledge and is quite simple, but several points must be taken into account. When working with an electric saw, you should remember that the engine does not tolerate voltage surges, which often occur in the countryside or in rural areas. Therefore, experts recommend using a stabilizer.

Some tips for working with an electric saw

Rule

First of all, you should not start the saw without first installing and adjusting the saw set: chain, bar and sprocket. If your saw is new, then the saw set requires running-in, which should take a few minutes. This will allow the sprocket, bar, and chain to break, and the oil will be able to get onto all parts of the saw set. As practice shows, this is the main cause of chain saw breakdowns. this is a bad circuit condition. In other words, a sharp chain is a necessary condition for high productivity, otherwise the operator needs to make additional efforts, and the service life decreases much faster. Therefore, it is recommended to sharpen the saw chain regularly. It is also important to pay great attention to lubrication of the chain during operation. Since modern saws are equipped with an automatic lubrication system, the user needs to monitor the oil level in a special tank.

Problems when sawing logs and their elimination

Sometimes the operator faces some difficulties while working with a power saw.
The main question that torments owners of electric-powered sawing equipment is why the saw cuts poorly or doesn’t cut at all? Very often, the manufacturer at the end of the instructions indicates a list of the most common breakdowns. This way, you can service the saw yourself and try to troubleshoot problems. Operators also often wonder why the saw cuts crookedly. As a rule, on forums you can find out approximate reasons for such phenomena. Most often, if the saw cuts to the side, this indicates that the chain links are dull. It often happens that the chain dulls unevenly. Try sharpening the working chain and continue working. In 90% of cases this solves the current situation.

Operating a chain saw: basic rules.

Before turning on any tool, for safe and productive operation, you must first learn the basic rules of working with it. Operating an electric saw or working with a chainsaw requires compliance with a number of rules that directly depend on the design features of this tool.

Rule

Chain Saw. This is not only a convenient and productive tool, but also quite dangerous. And inept handling of it can lead to dire consequences. Therefore, chain saw manufacturers pay a lot of attention not only to high technical and quality indicators, but also to safety systems. The most dangerous moment when using a saw is the so-called “kickback” - a sharp throw of the tool towards the operator. It occurs when the end of the saw bar “meets” the surface of the wood being processed. And stopping the chain quickly is the only way for the operator to avoid injury. This task is performed by a special inertial brake, the drive for which is a shield located in front of the operator’s left hand. It is a lever that can occupy 2 positions. Before starting, the shield is switched to the position “closer to the hand” and thereby “cocked”. At the moment of the reverse impact, the operator's hand rests on it, and the shield is activated, instantly activating the chain brake. In addition, it can change position without interaction with the operator's hand, simply due to inertia. Therefore, when operating a chain saw, the operator must hold the tool in such a way as to be aware of the possibility of kickback, be prepared for it and avoid possible injury.

Of course, it is impossible to calculate all the cases that may arise during the operation of a particular tool. However, we have tried to describe the problems that arise most often when using chain saws.

How to comfortably use an extension cord

When using an electric chain saw, be sure to use an extension cord. The length of the standard saw wire is 30 cm. If the connection of the wire plug and the extension cord is not securely connected, the saw bar may stop. They lead to a break in the chain and, accordingly, to failure of the tool.

The chain breaking during operation can also cause injury to the operator. Therefore, many summer residents use homemade devices to carry the extension cord and securely fix the connection.

There is no need for homemade mounts, since manufacturers of electric saws provide mounts for the extension cord in the design of the tool. In every chain saw model, this mount is a hole located on the rear handle of the tool.

In order to secure the extension cord in it, its wire is folded in half. Electric saws manufactured according to European safety standards are equipped with special plastic clamps. They ensure reliable fixation of the chain saw cord plug in the extension socket.

Checking the circuit

For high-quality work, you only need a perfectly sharpened chain. When processing wood, huge sawdust is formed, and no force is applied to immerse it in the material. You yourself will feel and see when it fades, namely from the corresponding small sawdust.

Check tension frequently. To do this, turn the adjuster until the chain slack is removed from the bottom of the bar. We take special protective gloves, lift the end of the bar and tighten the chain. With the correct tension, it will not come out of the groove, but will simply stretch with the movement of your hand.

Chain tension should be checked frequently to ensure safe operation of the saw. This is often done after adding oil, and if you have installed a new chain, you will have to inspect it even more often until it is used up.

If you learn how to saw , working with a chainsaw becomes a pleasure. And you will protect yourself and others from accidents.

How to choose a good electric saw: what to look for before buying a unit?

Holidays in the countryside can hardly be called passive. either you need to build a gazebo, or make a bench, or old trees need to be removed from the garden, sawing them into neat pieces to create decor. In addition to ordinary hand tools for wood. plane, chisel, hammer, jigsaw. Many owners have more severe equipment, for example, an electric saw for wood. With its help you can build not only a porch. all House.

Ergonomics of the unit

If the tool is used quite often, when choosing an electric saw, many people pay attention to the placement of the motor. Available in 2 versions. longitudinal and transverse. Experts believe that working with a saw with a motor on a tire is much easier. In addition, longitudinal units have the best balancing.
