How to attach the chain to the chain saw correctly

The procedure for installing a new chain has some differences, depending on the type of tensioning of the chain on the saw.

On tools with side tensioning, you must act in this way:

  • Release the brake. This is achieved by pulling the safety bar toward you until you hear a click.
  • Loosen the tension. To do this turn the tensioning screw with a screwdriver until the clamping nut rotates freely.
  • Lift the cover that holds the saw elements. To remove the chain, it must be removed from the sprocket guide bar (the guide bar is also removed). If you can’t, you have to loosen the tensioning screw more.
  • It is more convenient to start the installation of the new accessory from the top of the guide bar. It is put on top of the sprocket, and then the tire can be inserted back in, oriented to the guides.
  • Use the tensioning screw to tighten the chain: tensioning should be conducted with a slight slack in the chain.
  • The final clamping of the nut is performed after the guard is put in place.

Important:!Low-cost models like the ELITECH ZEP 2000 C40 or the STIHL MSE 220 C have this type of adjustment. Although somewhat difficult to change, these systems are more reliable than quick-change chucks.The sequence for installing a new chain on “quick tensioning” tools:

  • The first step is to remove the saw from the brake.
  • Open the nut knob until it locks.
  • The purpose of the wing nut in these designs is not only to secure the shield, but also to clamp the guide bar. Turn nut counterclockwise.
  • After removing the guard from the sprocket, move the bar in the opposite direction. This makes it possible to dismantle the old chain. The driven sprocket must be removed first.
  • When filling a new piece of chain saw oil, you also start with the sprocket. At this stage it is important to understand the direction of installation: at the bottom of the bar its cutting edge must “face” into the tool body.
  • The tension is set by adjusting the guide.
  • After the sprocket cover is installed, the cap nut should be tightened but not clamped.
  • The wing nut is tightened by hand at the very end of the procedure, after the idler wheel.

Main components of the lubrication system

Oil is normally supplied to the chainsaw lubrication system from a special tank, where it is periodically replenished. From there it is pushed by a powerful human oil pump, do this at regular intervals long enough for the previous injection. The main task of the oil mechanism is to prevent such situations when the lubrication on the chain becomes insufficient and, as a result, overheating of the cutting part is possible due to sharply increased friction forces. As a result, the chain can become dull and malfunctioning. Therefore, the oil must be constantly monitored. Typically, an electric saw’s lubrication system consists of the following components:

How To Put A Chain On A Chainsaw Properly

  • Chain oil tank;
  • Special oil filter;
  • The oil line, which is a small rubber hose that serves as an oil supply from the tank;
  • The oil pump, which pumps oil from the tank to the cutter;
  • Special transmission that transfers power to the pump from the engine.

Characteristics of the teeth

The teeth of a Makita electric chainsaw have some differences between them that are worth considering when buying a chain for a particular application. The sliding surface and the inclination of the cutting edge form a front angle of 55 to 87 degrees. Adjusting the angle of the upper blade only when sharpening. Any one of the links, its sharpness and magnitude, can affect the performance of a Makita chainsaw.

It is unacceptable to adjust tilt angles to any parameters, because there are approved standards that must be adhered to. Also the type of chain and its intended use are worth considering. The rear sharpening angle should be 45-63 degrees. It is considered the main angle, but it is very difficult to measure. It can be problematic if the other angles are not respected.

Choice of chain

The chainsaw chain is as important as the motor. And it is worth to choose it with maximum responsibility, it will help to avoid many problems during the further use of the tool. You should choose a chain for your chainsaw based on the following parameters:

  • Compatibility with electric saw model. Despite the large number of alternatives, it is best to buy the part from the same company that made the tool itself.
  • Purpose of use. If your electric chainsaw will be used for household chores at home or in the garden, it is best to choose a part with a chain pitch of 0.325″. A high-performance 3/8″ pitch chain will be needed for high volume applications.
  • It should be the same length as the bar length. One can eliminate elongation or sagging of the part during long hours of use by removing some of the links.
  • High-performance sawblades with a sharpening angle of 30° are recommended for more demanding sawing jobs. For difficult machining, e.g. wet or frozen wood, use a tooth sharpening of 10°.

It is also important to consider the material to be machined and how it will be sawn. Chains with a smaller sharpening angle are best for a longitudinal cut. Their productivity is not as high, but the service life is significantly increased.

The bar for the electric saw must also be chosen carefully. The more resistant the material, the longer the part will last and not break down. The following parameters are equally important:

  • Length (distance between stop and toe). the longer the distance, the larger the tree you can cut. Predominantly use 12-20″ lengths.
  • Groove width. up to 1.3 mm for household saws; 1.5-1.6 mm for more powerful tools.
  • Shank. determines whether the bar is suitable for a particular model of electric cooker. It is better to buy a branded part, although shanks from different manufacturers are often interchangeable.

Only with the right choice of sawing elements further operation of the electric saw will be effective, safe, not requiring additional monetary or time investments.

How to work with a sabre saw?

Sabel saw has not become widespread among domestic consumers. It is most similar to a hacksaw in structure and principle of operation. Only instead of human power, it is an electric motor. This tool is easy to use, because the ergonomic handle fits well in the hand.

Ideal for garden work where several branches need to be cut. Thanks to its thin work surface, the saw won’t cut unnecessary parts off. The advantage of the sabre saw is that it can cut not only wood, but also stone, ceramic materials, aerated concrete, glass, plastic, etc.д.

Chain does not turn on electric chainsaw. causes and repair methods

Most often the cause of this failure is a factory defect or deterioration of the plastic reducer sprocket, to which the electric saw bar is attached. During operation the drive sprocket is the first to take the load that is transmitted by the saw’s power pack. Over time, its teeth slip. After that, the motor and other important mechanisms of the electric garden tool begin to overheat.

attach, chain, chainsaw, correctly

At the first sign of malfunction you need to replace the sprocket immediately. To do this, you need to disassemble the tool and carefully remove the worn part. You will then need to clean the area underneath it of old fluid residue, and install a new sprocket. In the end, the part should be generously coated with thick oil.

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

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

How to put the chain on the saw?

To make it easier to put the chain on the saw, it is necessary to use the setting wheel. Then put on according to the plan:

attach, chain, chainsaw, correctly
  • The surface on which you place the saw should be flat;
  • Remove chain sprocket guard from chainsaw;
  • Turn tensioning sprocket to the right as far as it will go;
  • Put the chain on the securing part. Be sure to observe safety precautions so as not to injure yourself while you are doing this;
  • Put both pieces on the sprocket;
  • Reattach the cover;
  • Make sure the chain guides are in the right places;
  • Check condition of chain.

Why is the chain slipping?

Many chain saw users, even the most experienced ones, have had to deal with a chain jumping off the guide bar as they worked. The most common cause is insufficient tensioning or wear of the chain.

In 80% of cases, stretched chain links slip off the teeth of the drive sprocket, and the chain flies off the guide bar due to the centrifugal force. Sometimes the problem is caused by the wrong position of the sprocket in relation to the pivot or a chain saw bar that is not securely locked to the chain saw.

How to put the chain on the electric saw correctly?

It is worth noting that tool manufacturers do not forbid independent maintenance of the tool, and provide instructions on how to remove and install the chain on the electric saw. If we consider one of the most common types, where the chain tension on the electric saw is lateral, the algorithm looks like this:

  • Remove the protective shield and release the brake at the same time.
  • Use a screwdriver to turn the tensioning screw.
  • We unscrew the nut, which loosens the tension.
  • Remove the cover.
  • It will be necessary to separate the bar and the chain from the sprocket.
  • You need to remove the old chain from the bar and put the new one in its place.
  • Now all the previous steps are performed in reverse order.
  • The chain should be tightened with smooth movements, without jerks.
  • After the plastic cover is closed, you can make the final tensioning of the electric saw chain, using the nut and screw.

Manufacturers of power tools are tirelessly modernizing their devices, so new devices appear, greatly facilitating all processes related to the operation and maintenance of units. Today there are various chain tensioners for electric saws, often wing nuts are used, for quick intervention.
