How to Pull the Chain On the Echo Chainsaw. How to tension a chain on a chainsaw?

After you have worked with a chainsaw for some time, there will come a moment when the chain tension is loosened. This is due to its stretching and heating. Many do not know how to pull a chain on a chainsaw, so they begin to look for the answer in the instructions or on the Internet. Well, in this article you will learn how to do it right. The stretch is approximately the same for any chainsaw: at least Stihl, at least Husqvarna, at least Champion, at least some other.

What to twist on a chainsaw for chain tension?

In general, for all chainsaws, the procedure will look like this: weaken the fastening of the side cover and rotate the chain tensioner. But the cover fastening and the tensioner themselves can be different on different chainsaws.

The simplest option is a side cover attached with one or two nuts and a tensioner in the form of a bolt for a screwdriver (either slotted or cross). In this case, just loosen the nuts and turn the bolt clockwise. The bolt can be located either sideways in the cover, or in front. again in the side cover, or in the body of the chainsaw itself.

But there is also a keyless chain tensioner. this is when neither a key nor a screwdriver is required to loosen the side cover and rotate the tensioner. For different manufacturers, these systems look their own way. Below you can see in the figures what they are and what to twist.

How should the chain be pulled on a chainsaw?

The rule on how the chain should be pulled is as follows: the chain should move freely along the bus, but not sag. A little more, a little less. it does not matter. The main thing is to walk freely and not sag. In this case, if you pull the chain from the tire, grabbing it in the middle of the tire, it should reach the height of the links included in the tire.

During operation, make sure that the chain does not sag. If you notice a sag, tighten immediately. And after work, it is better to loosen the chain. This must be done because the chain heats up during operation and stretches (including because of this it has to be pulled up), and then, cooling down, cringe. As a result, it can tear itself, and ruin the tire, and withdraw the shaft bearing on which the drive sprocket is held.

That’s all the rules for chain tension on a chainsaw. Thank you for attention!

How To Tighten A Chain On A Carver Chainsaw. Necessary devices and tools for pulling the chain on a chainsaw

In order to properly perform pulling, you will need to know some simple mechanisms and simple tools. In Stihl chain saws, tensioning is simple. with the integrated chain tensioner. This method is as simple as possible and such a stretch is performed very quickly. To tighten or adjust the degree of chain slack, the manufacturer recommends doing this:

  • using the wing nut, unscrew the sprocket cover;
  • the rotation of the adjusting wheel determines the necessary chain length, pulling it to the desired degree;
  • The sprocket cover is closed again and the chain is securely fixed to the tire.

If it is impossible to tighten the chain of the chainsaw with the built-in mechanism, I use the following tools (for example, the Sparky saw):

  • angle grinder with a disc for metal;
  • hex wrench, diameter 5 mm;
  • piece of wire;
  • wooden stick or sliver;
  • flat screwdriver.

After de-energizing the saws, unscrew the screws with the hexagon, remove the housing cover, unscrew the tension screw with a screwdriver and remove the stem nut. The side of the screw adjacent to the saw body is ground with a disc. Then the saw is collected in the reverse order. A sliver is required to clean the case from sawdust.

How to Tighten a Chain on a Stihl Chainsaw MS 180 c. How to pull a chain on a Stihl chainsaw

If you saw the Stihl (Stihl) saw, don’t be scared and nervous, because I got one of the most reliable and high-quality options assembled from components created by one manufacturer at our own facilities.

Before you pull the chain on the Stihl chainsaw or check the quality of the tension, be sure to wear protective gloves or gloves. This will not only protect your hands from cuts on sharp teeth, but also keep them clean, since engine oil is difficult to wash and wash.

The first step is to check the Stihl chain tension. If the chain sags (a part of the internal teeth is visible), it is necessary to tighten it. When relaxed, it will damage the tire blade and render the saw unusable. If the chain is motionless when the brake is released, it means that it is overtightened; accordingly, it must be loosened.

Stihl offers two possible options for chain tension chains. fast and front. Both are used for improvement in the process. It is worth noting that pulling an overheated chain is prohibited. According to the laws of physics, it will shrink after cooling, and may burst from overtension or damage the tire.

In the frontal version, it is necessary to unscrew the nuts and lift the chainsaw tire on which the chain is mounted by the edge. The bolt on the right must be turned with a screwdriver until the desired tension is obtained. Then the tire must be raised even higher and the nuts tightened.
A quick version of the Stihl chainsaw chain tensioning involves the following: the tensioning wheel located on top must be turned all the way to the right, after lifting the wing nut handle and loosening it. After the operation, the nut is tightened again and the handle lowers. This ends the procedure. Stihl chainsaw models have some differences in the chain tension rules, it is advisable to find instructions for a custom model.

How to tension a chain on a chainsaw. How to pull a chain on a chainsaw

In almost every modern household today there is a chain electric or chainsaw. Sooner or later, most saw owners think about how to properly maintain and operate it, so that the tool is operational and does not lose performance.

Most users take sufficient care in relation to the engine, while forgetting to pay attention to other important components of the chainsaw, on the health of which its performance and durability depend to a large extent. Proper maintenance of all parts of the chainsaw will save you money and will extend the life of the device.

General device chainsaws

The topic of our conversation today will be the saw unit, which consists of a drive sprocket, tire and chain. The performance of the chainsaw depends on the serviceability of these parts even more than on the characteristics of the engine. After all, it’s no secret to anyone. it’s not a motor that is sawing, but a chain worn on a tire and driven by a drive sprocket. Let’s see what surprises can be expected after several weeks or months of operation, how to choose and maintain the components of our chain chainsaw.

How to String a Chain on a Makita Chainsaw. How to pull a chain on a chainsaw: installation and proper operation

Regardless of the class and purpose of the chainsaw, the cutting device includes a guide rail and a tensioner. The instructions contain information on how to properly tighten the chain on the chainsaw to eliminate additional stress on the engine and accelerated wear of the headset.

This element of the saw mechanism is used in conditions of high variable loads, therefore, in the process of work requires constant monitoring. A characteristic feature of the operating saw chains is an increase in size due to the formation of gaps in the links of the links.

and in the last quarter of the operational resource. During these time intervals, the headset needs special attention and careful maintenance.

  • The reason for the fast stretching of the saw chain may be the poor quality of the material of the budget model, the mismatch of the crown configuration and excessive wear of the drive sprocket, malfunction or inefficient operation of the lubrication system.
  • The full-fledged operation of the chainsaw chain also largely depends on the condition of the tire and the drive sprocket, the quality of the chain oil and the performance of the lubrication system, the timely and competent sharpening of the edges of the cutting links.

According to professional filers, the headset’s durability is reflected in the operator’s work style and level of operational loads. The chains of the budget group are more susceptible to stretching; the more expensive corporate assortment has no comments on the technical and working properties.

Negative effects of improper chain adjustment

Checking the condition and chain tension is included in the mandatory list of preparatory work.

On how you can correctly put the chain, it depends:

  • the duration of its subsequent operation;
  • safety of cutting operations of increased complexity;
  • engine resource and chainsaws in general.

Overstretched headset dramatically reduces productivity, initiates excessive loads on the power unit and transmission. There is also tire overheating and excessive fuel consumption.

A loose chain may fly off the tire or break. The formation of traumatic moments is partially or completely eliminated by emergency stop systems and catchers, which can more or less unravel the chainsaw chain and determine its suitability for subsequent operation.

Installing a part with damaged or deformed links can lead to uneven wear on the guide groove of the tire and other undesirable consequences.

Tensioning devices

The classic chain saw chain tensioner budget class, as a rule, is a threaded bolt with an adjusting component, standard or side location. The chain tension is adjusted using the included key or a screwdriver.

expensive models are equipped with easy-to-use devices that allow you to tension the chain with one movement of the lever or by turning the adjusting dial.

In the first case, the degree of tension is fixed by a lock nut, in the second case, the tire and chain tensioner are locked in a predetermined position by installing a cover. In both versions, reliable fixation of the chain in a predetermined position, the ability to compensate for its drawing with minimal loss of working time, is guaranteed.

Benefits of developing a chain kit

The chain and the tire are included in the list of interchangeable equipment, so the sawyer, depending on the characteristics of the work, can use several headsets of different lengths and performance. The average service life of wear-resistant branded tires allows you to develop a resource of three saw chains.

The cutting edges of the chain saw links need periodic sharpening. The undeniable advantages of operating a set of several chains are uniform wear of the drive sprocket and good compatibility with the chains included in the optional set.

Features of manual and mechanized sharpening

Blunting the cutting edges of the saw chain is manifested:

  • noticeable decrease in performance;
  • ejection of small chips;
  • the appearance of a characteristic smell of burnt wood.

To restore the cutting properties of the chains, several types of grinding tools are used.

In the simplest version, it is a holder fixed to the bus, complete with, in another, with a power drive. Both technologies have their own advantages and disadvantages.

Low productivity and time consuming contributes to the conservation of its resource. The mechanized method provides good performance, but the lack of an individual approach to each cutting link of the chain negatively affects its durability.

Chain replacement and adjustment sequence

It is technically simple to change the chain of a chainsaw of a household and professional level on its own. The key to the successful implementation of the adjustment work will be the exact observance of the recommendations of the attached instructions.

Due to the thermal expansion of the metal, the installation of the chain on a chainsaw and subsequent adjustment is carried out only on a cold tire.

  • In the classic solution, the technology provides for the inclusion of blocking from accidental starting of the engine, unscrewing the threaded fasteners, dismantling the tire and cleaning the guide groove from sawdust.
  • Next, make sure that the size of the shanks matches the groove width, determine which side to put the chain on the chainsaw, fasten the tire and adjust the chain in the sequence indicated by the instruction.
  • Before you put the chain on the chainsaw, you should make sure that the direction of the chain on the chainsaw meets the stated requirements, and the chain tensioning mechanism has a sufficient clearance.

After adjusting the new chain, it is recommended to run the saw at medium speed for 2-3 minutes, and then check the chain tension again. This point can be combined with visual inspection of the lubrication system.

Methods for checking the degree of tension

To check the degree of tension, it is enough to pull the chain in the middle part of the tire, the output of the link shanks is allowed no more than 2/3.

  • A normally adjusted chain should not jam when moving manually on the bus.
  • Squeaking and other extraneous noises in the area of ​​the leading sprocket are also excluded.
  • After running the chain, it is necessary to check the tightness of the threaded fasteners of the tire and the protective cover.

After prolonged use, the chain does not stretch due to a lack of adjusting stroke of the tensioning mechanism. The design of the circuit allows you to reduce its length by removing several links. On the other hand, such savings result in a loss of smoothness of the chain and forced wear on the groove of the tire and the crown of the drive sprocket.

How to properly tension the chain of electric and chainsaws. How to put a chain on a chainsaw: direction

When considering how to correctly put the chain on a chainsaw, we note the moment that the modern version of the tool has a special mounting wheel. Due to it, the procedure is greatly simplified. Among its features, we note the following points:

  1. Considering how to properly put a chain on a chainsaw, we note that for a start you should prepare a flat surface. Due to this, the probability of damage to the tool can be eliminated. After that, the main part of the tool, the tire and the chain are laid out separately.
  2. The next step is to remove the protection, which is designed to protect the sprocket. In most cases, it is fixed using a conventional wing nut.
  3. On the tire, the tension sprocket turns to the right until it stops. It is in this position that the tool is installed.
  4. Next, the chain is gradually superimposed on the locking element. A fairly common question can be called on which side this element is posed. Installation starts from the top, the chain rotates so that the tire is on top. Such operations should be performed exclusively with thick gloves that can withstand the impact of the cutting edge. The cutter on the end surface should be located forward.
  5. Both elements are worn on an asterisk.
  6. The next step is to re-attach the chain sprocket cover. It is important to ensure that the pins align with the holes. Improper fixation can cause rattling or other problems.
  7. It is necessary to ensure that the guides fall into a special gutter.
  8. The condition of the chain is checked visually after it is fixed.

Why the chain on the chainsaw is released. Classic mistakes when pulling chainsaw chains

The following problem may occur on chain saws. the chain starts to fly off the saw. There are several reasons for this problem, the main of which are the following:

  • The presence of problems with an asterisk;
  • Stretching;
  • Problems with the bus.

One of the most popular mistakes is the use of low-quality components. Each of the chains has its own life, the chain is considered the most worn out element of all parts. The metal is prone to deformation during various loads, which contributes to the fact that the chain becomes longer by about 1 cm, while it is significantly dull. It is strictly forbidden to pull the old chain onto the saw; it is imperative to purchase a new component.

Problems may also occur at the mounting location of the tire. In most cases, the casing is fixed with a bolt; this mount is otherwise called a motor unit. The tire mount and drive sprocket must be closed with special protective covers. In cases of bolt loosening, the degree of vibration in the tire increases, which contributes to its excessive mobility. If the chain stretching is caused precisely by the loose tire, then you need to fix the tire, and then check how the saw functions.

Also, a classic mistake when pulling the chain can be the existing problems with the asterisk, which were not resolved in a timely manner. If the sprocket is of poor quality, the saw chain needs a stretch, since the process of its sagging cannot be avoided. It is necessary to fix the tire sprocket, first remove the protective cover and candles, after which it will be necessary to pull out the air filter. The next step is to install the stopper in place of the spark plug. The main task of the stopper is to fix the piston. Then you need to scroll the clutch disc in the direction of rotation of the clock. A special key can be used for this, or a universal key designed for an angle grinder.

It is necessary to ensure that the piston is installed in the extreme location. When looking at the hole for screwing in the candles, the piston should be located at the bottom. After the piston is locked, it is permitted to start clamping the drive sprocket. The final step will require all the details you need to assemble in the reverse order.
