How to put a chain on electric saw

How to put the chain on the electric chainsaw correctly. tensioning, adjustment

Among the useful things stored in the back of the household owners of country plots, you can always find gadgets and devices for cutting wood. It can be a jigsaw, a hand saw, a handy electric saw or a powerful unit running on liquid fuel.

Any of the “helpers” requires certain skills and care. For example, owners of a tool that runs on electricity, you need to know what kind of chains for electric saws, whether it is difficult to change them yourself and whether the file is suitable for proper sharpening.

Large-scale logging or serious outdoor construction work requires a more powerful tool. a chainsaw.

However, if you need to occasionally touch up a fence, make repairs to the house or saw a few logs, then the ideal tool is an electric saw.

It is convenient to use it in limited spaces. inside the house, in a barn or utility room, and in the field if there is a power source nearby.

What other benefits do power tools have?? It does not require time to prepare the fuel mixture and cuts more accurately than gasoline analogues. Minus one. gentle mode of operation. You’ll have to get used to the interval sawing of wood. That means, that after 40 seconds of work the saw needs a “rest” of about 20 seconds.

So, if you are already the happy owner of an ergonomic, comfortable electric saw, prepare for the fact that you will have to become more familiar with the device, replacement and sharpening of the chain. the main dynamic part.

Before you choose a chain saw, look for information about overheat protection. A protected motor lasts much longer and operates more efficiently

Upgrade the cutting part of your saw with your own hands

To solve the problem of sharpening the chain, special devices are used. Work according to tooth configuration. One of cutting edges has slightly beveled top part, so during intensive work operator needs to make 2-3 tool sharpening.

The interaction of the cutting edge with the ground blunts it, and the chips change their size. The saw slides across the surface of the wood as it is being worked on. The main sign of a blunt tool is an increase in feed torque and fine shavings. When working with blunt tools the operator gets tired quickly, and the result of work changes not for the better.

The tool is prepared for the sharpening job:

Given the contours of the tooth surface and the metal composition of the chain links, use a round file for sharpening. The key to good sharpening is to have the file in the correct direction while sharpening the tooth. The top part of the file is raised over the tooth edge by 20% of the tool diameter. Hold the file at 90° vertically and 30° horizontally.

The file grip is clamped on the tooth and the tool touches it snugly, allowing the file to be held at the proper height for the job.

Secure the tire before starting work. The first movements of the file should be smooth, gentle, and with regular turns of the instrument. First renew the teeth in one direction, then sharpen the opposing elements.

It is necessary to distribute the pressure on the teeth evenly and make the same number of movements with the file.

Use a template to prevent the depth stop from being ground and place it in the slot when inserting the accessory. It is not permissible to change the links while working, otherwise there could be a malfunction in the saw. The use of special kits allows correct sharpening of the tool with an even finish of the tooth edges.

The general scheme of the operation consists of several points

  • securing the chain brake;
  • The mounting of the tool according to a template;
  • marking of the first tooth;
  • directly performing the process.

Correctly performed installation of the chain on the wood cutting tool will prevent technological losses, make the whole work process safe, allow to cut wood for any purpose without problems.

A chainsaw can be used for quite a lot of work. The main cutting element of such a tool is represented by a chain with various blades. Modern versions are characterized by the fact that they can be serviced independently. When cutting for a long time or not following the basic recommendations, the cutting edge wears out quickly. This is why it is necessary to remove and sharpen the chain and then install it. Such a procedure is characterized by quite a lot of features, which we will talk about in more detail below.

Step-by-step installation algorithm

Not all modern chainsaws are equipped with an adjustment wheel, which makes it much easier to set the saw. Systems with an adjustment wheel are usually uncommon among home chain saws

That’s why it is very important to know the technology and the sequence of chain installation on the chainsaw

Key points to pay attention to:

  • Prepare an even surface on which you will assemble the chain and bar. This will minimize the chance of damage to the chainsaw or loss of small parts. On the prepared surface, lay the bar and a parallel chain next to it.
  • Remove the sprocket guard, on modern chainsaws enough to unscrew the fender nut, on older models may require a wrench of the appropriate size.
  • At the base of the guide rod, turn the sprocket all the way to the right. Only in this position will the chain be installed.
  • Then place the chain sequentially, link by link, on the mounting grooves on the guide rail. Put the chain on top of the guide bar, gradually return it so that the bar is always on top and the chain at the bottom, this will allow it to always be tightened and without problems fit into the guide bar groove. When doing this step, be sure to wear thick protective gloves because your fingers are touching the cutting edge. When viewed from above, the cutter is always forward to the end of the guide rail.
  • Put both the bar and the chain on the drive sprocket.
  • Secure the chain sprocket cover in place. Make sure all fastening pins are positioned with holes. Incorrect installation with distortion or incomplete can lead to extraneous noise, thunder.
  • Make sure the rails “fit” into the special mounting groove.
  • After installation, check that the chain is securely attached to the chainsaw and to the bar. Everything must be firmly seated with no backlash.

The amount of tension in the chain after installation is important. Setting the correct tension is easy and takes less than three minutes. First you need to unscrew the nuts on the protective cover. Using a freely rotating adjusting screw, fix the correct tension so that the chain is NOT pulled away from the edge of the guide bar more than 3 to 5 mm.

Only need to tighten the nuts and check the tension. If it needs to be corrected, adjust the tension again.

How to install the rod and chain on the chainsaw, see below, where a clear algorithm of actions is presented:

How to properly adjust the chain tension

This has a direct impact on the safe operation of the chainsaw, its efficiency and the service life of the chain. It is very easy to check the tensioning level: take the saw blade closer to the bar and pull it upwards. At normal tension 1/3 of the tip should remain inside the nose and the chain can be safely rotated by hand.

Different models of electric saws have a chain tensioner in the form of a wing nut or a screw:

  • For power tools with quick tensioning system, make adjustments by rotating special wheel under the sprocket cover. Turning clockwise tightens the saw blade, counterclockwise loosens it. With this mechanism, the tension can be changed as you work.
  • Tension adjustment on electric screw saws is a little more complicated. It is necessary to loosen the tensioning screw and the side nuts and then it is possible to turn the screw. With tensioning the chain, you need to turn the chain forward to check the smoothness of movement, eliminate the play of the joints.

All work must be carried out with the electric saw unplugged.

As you use it, and especially with the high volume of work you do, the chain on your electric chainsaw wears out and becomes loose. If it is not replaced and tensioned beforehand, it could render the machine unsafe to operate, for example by coming loose while you are sawing.

To attach a chain to your power saw, you must take into account the chain‘s characteristics and in particular the tensioning of the chain on the machine. In the case of side tension, the sequence of actions is as follows:

  • Release the brake by pulling the cover plate toward you until it audibly snaps into place.
  • Using a screwdriver, unscrew the tensioning screw, loosening the chain tension. The clamping nut will then rotate freely.
  • Remove the old part. Open the section where the sawblades are located by lifting the cover on the housing and then remove the chain from the guide bar (sprocket), the bar must also be removed. When parts cannot be removed, it is necessary to loosen the tensioning screw.
  • Install the replacement part on top of the sprocket, starting with the upper tire section. Then, using the guide bar as a guide, insert it back into the storage compartment.

The replacement may look complicated, but it ensures the reliability of the whole system compared to tools equipped with quick-change chucks.

To change the saw element on electric saws with a quick tensioning system, proceed as follows

  • Remove the tool from the brake.
  • Open the handle nut until it locks.
  • Turn the wing nut counterclockwise. This element serves as both a cover lock and a guide clamp.
  • After removing the guide bar guard, slide the bar in the opposite direction. Release sprocket, remove old chain.
  • Install a new chain along the entire length of the bar, starting with the sprocket, so that the cutting edge faces inside the body of the electric saw.
  • Adjust the guide rail to set the tension.
  • When the sprocket cover is in place, tighten the fastening nut without tightening.
  • In the direction of the arrow indicated on the body turn the tensioning wheel, then tighten the wing nut.

Features of the cutting part of the chainsaw

When buying an electric saw, it is important to pay attention to the following components:

The circular saw is a kind of tool.

Quality examples of such tools are characterized by the highest performance. Such models are permanent, do not change their data as a result of constant friction and can operate under any adverse conditions. All chainsaws have 50 main links. Their pitch corresponds to 3/8, the groove is 1,3 mm. In some cases, the choice of this element depends on some features:

  • The electric chainsaw’s instructions must be followed precisely;
  • information on the quality of the chain;
  • familiarity with the pitch of several links.

Devices with 52 links have a spacing of 38 at a groove of 1.3 mm and a bar of 36 cm. Power saws used in the toughest conditions are equipped with tracks made of special alloys.

Chain does not rotate on electric saw. causes and repair methods

The most common causes of this failure are a manufacturing defect or wear of the plastic sprocket on the transmission unit where the guide bar for the electric saw is attached. During operation, the drive sprocket is the first to take the load that is transmitted by the power unit of the saw. Over time, the teeth will slip. After that, the motor and other important mechanisms of an electric garden tool begin to overheat.

At the first sign of trouble you need to replace the sprocket right away. To do this, disassemble the tool and carefully remove the worn part. Then it will be necessary to clean the place under it from the old fluid and install a new sprocket. Finally, you will need to lubricate the part generously with thick oil.

In some cases it is not the built-in sprocket that malfunctions, but the parts next to it. Highly stressed parts are the clutch cup, the spring, the bearing and the cam. As a rule, these parts cannot be repaired, so the operator will need to replace the defective parts before other elements of the chainsaw fail.

To prevent excessive wear of drive components in the future, you need to constantly monitor their condition and the amount of lubrication. The user of the garden saw should inspect the gear and pinion at least once a month and, if necessary, clean them and change the lubricant.
