How to put a chain on a Makita saw

Fitting the bar to the saw
There is a slot at one end of the tire and two holes on the sides of it. When installing the tire with a slot, put it on a special pin on the saw body, and one of the holes on the pin of the tensioning mechanism.

The second hole on the blade serves to transfer grease from the oil channel to the groove of the tire.

Installing the chain
The chain is pulled over a drive sprocket located on the saw body and over a sprocket at the end of the bar. When installing the chain, you must take into account the correct direction of its rotation, which is usually indicated on the product itself..

After installing the chain, the saw sprocket is closed with a cover, the clamping nut of which is not tightened to the stop so that the bar is not completely clamped.

Chain tension
Adjustment of the chain tension on Chinese saws is carried out using a special tension screw, the head of which has a slot for a screwdriver. It is located at the end of the device body. For tighter chain tension, rotate it clockwise..

The tensioning screw is turned until the chain slack disappears. After that, it is manually scrolled on the tire towards the saw body. This is necessary in order to “straighten” the teeth of the chain in the groove of the bar.

If the chain is loose after spinning, then tighten it again..
After that, the tire is taken by its free end, lifted up to the stop and in this position, the chain slack is again eliminated..

At the last stage, the clamping nut is completely tightened on the casing covering the saw drive sprocket. At the same time, the tire is kept in the “raised” position.
A correctly tensioned chain should be freely removed by hand from the grooves of the tire on its two sides by about 3-4mm, and when lowering, lie back into the grooves.

Checking the tension after work
Once the chain is tensioned, it is only after a little operational testing that you can finally check the quality of its tension. For this purpose, several test cuts are made with it..

It is not uncommon for the chain to loosen after test cuts. This happens when its links were contaminated, and during operation this contamination was dissolved by the lubricant..

If this happens, then the chain must be re-tightened, having previously slightly loosened the clamping nut on the casing and lifting the free end of the bar up. the saw, of course, must be disconnected from the network before this.

At the end of the chain tension adjustment, always check whether it goes in the right direction without tension, whether it is overtightened. To this end, it is unblocked by pressing the start button and pushed forward by the teeth with a screwdriver. If she moves a little by inertia, then everything is fine..

The bar and chain are the saw’s working duo, responsible for efficient and accurate cutting of wood. The modern market is literally overflowing with all kinds of tire and chain models that are suitable for certain purposes. How do you choose the right parts from the entire range presented? We will answer this and other questions together..

How to Lubricate a Saw Chain – Procedure for Beginners

As a rule, the saw chain is lubricated using a quality automotive oil. The only important point is that you should not use waste formulations, as they will only harm the garden tool..

The saw must be disconnected from the power supply before adding oil. If the saw is equipped with an automatic oil supply system, then the lubricant must be poured into a separate container of the tool, and then start work.

If you notice that the chain on the saw is not lubricated even if there is a large amount of oil in the reservoir, then first of all you need to check the plunger pump of the tool. In most models, it is made of soft plastic, and the teeth on it deteriorate very quickly. In such cases, replacing a part will be quite expensive, which is why many owners prefer to buy new saws..

If there is no such automatic lubrication system in the saw, then the chain lubrication is performed in a completely different way. To do this, dip the chain in oil and then put it back on the saw. The chain must be lubricated abundantly, otherwise, due to lack of oil, the saw motor will be subjected to heavy loads..

Saw chains: how to pick up, sharpen and set back

The bar and chain are the working duo of the electric saw, responsible for efficient and accurate cutting of wood species. The modern market is almost full of various models of tires and chains that are suitable for one or another purpose. How to choose the right parts from the entire range presented? We will give answers to this and other questions together.

How to choose the right chain for a saw – we understand the details

In terms of its importance, the chain is often placed by experts on a par with the saw motor. Therefore, if you want to choose a suitable sawing element, you should approach it with special responsibility. To choose a chain for a saw, you should pay attention to the following parameters:

Makita Battery Chainsaw XCU04: Chain Install

Saw compatibility – in other words, you should choose a part that was released by the manufacturer of the tool itself. In this case, the risk of making a mistake and purchasing an unsuitable sawing element is reduced to zero;
Determine Your Chain Purpose – If you are looking for a high performance sawing element, choose a 3/8 inch part. If the saw is used only for solving simple household tasks, then the purchase of a saw element with a chain pitch of 0.325 inches will be optimal;
Sharpening angle – this parameter is important for further repair, maintenance and restoration of the saw element. More efficient chains have a 30 ° sharpening angle – such sawing elements can more easily take high loads. However, for complex wood processing – if it is frozen or damp – you should stop on a chain with a sharpening angle of 10 °;
Saw bar length – must match the length of the saw bar. Even if the chain stretches and sags over time, this problem can be solved by removing a few links..

In addition to these parameters, the method of cutting and the material that can be processed should be taken into account. Be sure to keep in mind that for the purpose of longitudinal cutting, a chain with a small sharpening angle will be optimal. The performance of such a chain will be slightly less, but its service life will increase significantly..

How to put the chain on the saw correctly – a detailed algorithm

Having chosen the sawing element for your tool, you probably wondered how to put the chain on the saw with your own hands. In fact, there is nothing complicated in this procedure. All that is required of you is to carefully study the specified algorithm and observe it when working..

How to sharpen a saw chain with your own hands?

Many craftsmen sharpen a saw chain at the first sign of wear on its cutting teeth. However, it is not possible to use any specific tool for this procedure. To work, you need to stock up on a whole set of special equipment. To do this, you will need:

Flat file – it is needed to adjust the depth gauge;
A round file that has a mowing line of a landmark;
Caliber;
Rim – it will help in determining the angle.

When using a round file, make sure that it protrudes no more than 1/5 of its length above the chain teeth. The first sharpened tooth of the chain must be marked with a marker so as not to go on the second circle.

Sharpening the saw chain with your own hands should be performed with precise and rhythmic movements and only in one direction. After making a few sharpenings, proceed to processing the limiter – over time, it wears out and loses its shape. When working, apply the gauge with the end side to the edge of the stopper. If the stop is far beyond the caliber, then it will have to be trimmed with a flat file. In this case, the gauge should be located strictly perpendicular to the saw bar.

It is impossible to visually determine the result of sharpening the chain. You can only find out if you did everything right when sawing wood..

Features of the choice of a bar for a saw

When buying a tire, the first thing to look for is the material from which it is made. The chain is secured on when the saw is continuously loaded properly. If it is strong and reliable enough, then the part will serve for a long time and properly. In addition to the material, when choosing a tire, you need to study its such parameters:

Shank – Use this to determine if the bar matches your saw model. If you do not pay attention to the condition of the tool, if the chain is tensioned as it happens. It’s all about the location of the saw tensioners and chain oil holes. Most of the well-known brands produce branded shanks for their saw models. How to choose a saw and what to look for. Pick up the saw device. In this case, shanks from different companies can replace each other;
Groove width – in today’s market, you can choose tires with a groove width of 1.1 and 1.3 mm for low-power household saws, as well as 1.5 and 1.6 mm for more powerful saw models;
Saw bar length – this parameter is one of the most important when choosing a part. To determine the length of the saw bar, you will need to measure the distance between the tip of the bar and the bumper. Most often it is 12-20 inches – it all depends on the saw model. How to properly fit the chain on to install the chain on the saw. The longer the selected tire, the larger the tree you can cut.

How to choose the right chain for a saw – we understand the details

By its own importance, the chain is often put by professionals on a par with the engine of an electric saw. Therefore, if you want to choose a suitable sawing element, you should approach it with special responsibility. To choose a chain for an electric saw, you should pay your attention to the following characteristics:

Comparability to an electric saw – in other words, you should choose a part that was released by the manufacturer of the tool itself. In this case, the risk of making a mistake and purchasing an unsuitable sawing element is reduced to zero;

Determine Chain Challenges – If you are looking for the highest performance sawing element, choose a part with 3/8 ”increments. If an electric saw is used only for solving light household tasks, then buying a saw element with a chain pitch of 0.325 inches would be good;

Sharpening angle – this parameter is important for the upcoming repair, maintenance and restoration of the saw element. More efficient chains have a 30 ° sharpening angle – these saw elements are easier to handle the highest loads. Nevertheless, for the purpose of complex processing of the wood species – if it is frozen or wet – it is necessary to brake on a chain with a sharpening angle of 10 °;

Saw bar length – should match the length of the electric saw bar. Even if the chain stretches and sags over time, this problem can be solved by removing a few links..

In addition to these characteristics, the cutting method and the material that can be processed should be taken into account. Be sure to keep in mind that for the purpose of longitudinal cutting, a chain with a small sharpening angle will be good. The performance of such a chain will be slightly less, but its service life will increase significantly..

The chain does not spin on the saw – reasons and repair methods

The most common cause of this breakdown is a factory defect or wear on the plastic gear sprocket to which the saw bar is attached. During operation, the drive star is the first to take on the load, which is transmitted by the saw’s power unit. Over time, her teeth lick off. After that, the motor and other important mechanisms of the electric garden tool begin to overheat..

When the first signs of a saw malfunction are found, the chainring should be replaced immediately. To do this, you need to disassemble the tool and carefully remove the worn part. Then you need to clean the place under it from the remnants of the old fluid, and install a new star. At the end, the part will need to be abundantly lubricated with thick oil..

In some cases, it is not the built-in asterisk that fails, but the elements located next to it. High stress components include clutch cup, spring, bearing and cam. As a rule, these parts cannot be repaired, so the operator will need to replace the defective parts without waiting for the other parts of the saw to fail..

In order to prevent increased wear of the drive parts in the future, you need to constantly monitor their condition and the amount of lubricant. The user of the garden saw must inspect the gear and gearbox at least once a month and, if necessary, clean them and change the lubricant..

What to do if the chain sags

If the chain slack, there is a risk of injury to the operator – the saw blade could break or simply fly off the guide sprockets. Of course, modern chainsaws have safety and emergency stop systems, but these systems do not always work correctly..

It is important not to install a chain with defective or damaged saw links on the chainsaw, in addition to the danger of breaking at any time, such a chain will sharpen the guide grooves of the bar, which will lead to its distortion, uneven cut and failure of the guide bar.

Because of which the chain can sag during even short periods of operation.?

There may be problems with the guide bar. Sometimes, due to an oversight of the operator or due to severe wear of the threads of the fixing bolts at the point where the guide bar is attached, vibration may occur, which causes the chain to loosen. It is necessary to check the condition of the fixing bolts and, if necessary, replace them with new ones. When the bolts are sufficiently tightened, this problem does not arise..
With enough careful handling of the chainsaw, over time, any chain can wear out. Trying to repair it or collect one from several is a useless exercise. If the chain headset has stretched due to natural causes, then it is best to get a new one..
The asterisk is skewed. Sagging can occur due to the misalignment of the sprocket teeth. In this case, it would be best to contact a service center to repair and adjust the position of the guide sprocket. It is quite difficult to fix the drive sprocket in the correct position, because you will have to dismantle many small parts, remove the guide rail, and then reassemble everything in the reverse order..

Why does the chain come off

Many, even the most experienced users of chainsaws, have encountered in their life a situation where the chain jumped off the guide bar during operation. The most common cause is insufficient chain tension or wear..

In 80% of cases, the stretched chain links slip from the teeth of the drive sprocket, and it flies out from the guide under the action of centrifugal force. Although sometimes the problem appears due to the incorrect position of the sprocket relative to the axis of rotation or a loose saw bar on the chainsaw.

Other circuit parameters:

Profile. This refers to the height of the chain’s cutting edge above the bar. According to this indicator, saw chains are divided into two types: low-profile and high-profile. Low profile chains are safer to use, while high profile chains provide high productivity. In addition, the chains are distributed along the profile of the cutting teeth: semi-chisel. chisel, rounded and victorious teeth.

Cutting depth. In other words, the gap between the saw tooth and the stop. For household chainsaws, it is correct to use chains with a clearance of 0.025 ″ and 0.03 ″. Chains up to 0.07 ″ clearance available on professional and industrial models.
The number of links. When choosing a chain for a chainsaw, focus on the length of the bar. For example, if you have a Chinese household saw with a 14 “bar, chances are you need a 52 link chain..

Important! The correct selection of a chain for a chainsaw is carried out in accordance with the parameters specified in the instruction manual.

Saw chain

As with chainsaws, the main working parts of an electric garden tool are a bar and a chain. The performance of the chain saw, the volume of fuel it regularly consumes, as well as the quality of the mowing line for cutting wood largely depend on their quality and technical parameters. In order to constantly maintain the stable operation of a garden tool, its owner must study the rules for choosing, installing, maintaining and repairing a cutting set. This will keep the bar and saw chain in order until the end of their service life..

How to untangle a chainsaw chain

When removing an old chain or putting a new chain on the guide bar of the chainsaw, it can become tangled. It can also happen with careless transportation. When the chain is tangled, it folds into rings.

Due to the lack of flexibility in the transverse direction, it is very difficult to untangle it with bare hands, because when you try to untangle one ring in another place, a new ring is formed..

It is necessary to put the chainsaw chain on a horizontal surface and spin the rings in different directions, while pulling the blade in such a direction that the diameter of the rings increases. Sooner or later, the chain will unravel into its natural position.

There is another way – you can rivet one link of the chain and straighten it, then connect it into a ring and rivet the riveted links back.

A correctly matched and compatible bar, chain and saw will allow you to work efficiently and calmly without wasting money and time.

To install the chain on the saw, you need to proceed in this order:

First, you need to move the protective shield, while lowering the brake lever;
Then use a screwdriver to turn the tensioner and unscrew the nut. Thus, you will loosen the tension of the old chain;
Remove the cover and separate the bar and chain from the sprocket;
Then remove the old chain and replace it with a new sawing element;
Then place the bar on the saw and adjust the chain tension with the screw. Try to tension the new chain smoothly without jerking..

Lower the brake lever and unscrew the nut;
Dismantle the cover and move the tire back a little;
Remove the old chain and fit a new saw blade. In this case, the new chain is mounted first on the dismantled sprocket, and then along the entire length of the bar;
After that, the sprocket must be installed in place and the nut must be tightened..

At the end, it remains to turn the tension wheel in the direction shown by the arrow on the body, and tighten the thumbscrew to the end.
