Loose tire
When the chain tension is reduced, the problem is often accompanied by a weakening of the tire itself. To check its condition, you need to inspect the place between the top plate on the headset casing and the inner surface on the case. When the locking bolts are loosened, the bar begins to move, which can be seen by the characteristic vibration during sawing. With frequent use, it is recommended to regularly clamp the bolts.
Figure 1. Loose tire
If you decide to tighten the tire yourself, you need to find and lower the chain brake. Return the tensioning screw so that the chain fits snugly into the grooves. After that, pull back the chain in the direction of travel, if it is too tight, loosen the screw.
How to properly put a chain on a chainsaw?
In most chainsaw models, the chain is easy to put on the tire by unscrewing the main screw, then the links must be placed on the drive sprocket. Before starting work, the general condition of all cutting surfaces and the guide groove and setting wheel should be inspected. Often, dirt and small chips accumulate in it, which will subsequently lead to planned repairs, deterioration of sliding. Step-by-step algorithm of work:
- Loosen the screws securing the sprocket protection cover, usually it is tightened with a wing nut.
- Return the tensioning sprocket to the right until it stops.
- Will overlay links to the headset starting at the top. Drink so that they fall into the corresponding grooves.
- Replace the chain sprocket mount, tighten the nut. Guides Must fall into a special chute.
- Release the chain brake, pull the chain along the mowing line to check the tension. Tighten the tensioner lever if necessary. Figure 4. Installing the chain on the chainsaw
The setting wheel should rotate freely after installing the chainsaw chain. At the end of the work, it is imperative to lubricate all moving parts of the tool to avoid rapid wear.
Trouble with a leading star
Sometimes chain slack is due to drive sprocket problems. The most common situation is when it is poorly secured. Step-by-step algorithm to Twist the asterisk:
- Remove the engine cover.
- Remove the air filter and Unscrew the candle, put in its place a special stopper to fix the piston in an immovable position.
- Use the angle grinder wrench to rotate the clutch disc clockwise to the highest position. Check the tightness of the sprocket, adjust its position. Figure 3. Driving star on a chainsaw
After tightening, reassemble the chainsaw, be sure to put on the protective cover. When assembling, check that the chain fits snugly on the bar.
How to put a chain on a chainsaw correctly: instructions, recommendations, basic methods
Chain. An important structural element of the chainsaw. It is she who has the greatest load during work, so high-quality and systemic care is required. When using any model, it is important to know how to put on the chain correctly. Watch its tension. If fastened incorrectly, there is a risk of stretching and exiting the grooves. Reduced saw performance and increased risk of injury at high power.

The chain stretched
Any functional changes in the chain lead to a decrease in the productivity of the tool, injury during operation.
It should be regularly monitored so that there is no deformation of the metal and stretching of more than 1 cm.
If such a problem still occurs, you need to purchase a new circuit or correct the old one.
Disconnect the chain links on the machine or fix it in a vice, file off the rivets and knock them out with a bit (it is not recommended to use an angle grinder).
Remove 1-2 links depending on the chain stretch. After that, put all the elements in place, insert the rivet and beat it off with a hammer, use a special rivet tool. For reliability, it is recommended to use a welding machine. At the end of the work, grinds off excess and burrs with a thin file.
Fitting the tire on Stihl and Husqvarna
Chainsaw models from the manufacturer Stihl may differ during the assembly process. Step by step guide:
- Open the wing nut, remove the chain sprocket cover. Return it on the tire all the way to the right.
- Place the chain on the bar, starting from the top, the cutting tooth on the top side must point straight ahead.
- Attach the assembled tire to the chainsaw, pull the structure over the sprocket. Slide the guide onto the shoulder bolt. Close the cover, hit the pins in the holes provided by the manufacturer.
- Turn wing nut until sprocket cover is in contact with motor housing.
- Clamp bolt back forward, drive links Must fit into bar grooves. Tightens the wing nut completely.
At the end of work, check the tension, if the headset does not move well, adjust the tension with a nut. Apply the chain brake before starting.
The Husqvarna saw chain installation algorithm is almost identical. The main difference. In most models, the tension and adjustment of the position of the headset to the body is controlled by not one, but two wing nuts. A separate adjustment lever is rarely found on the protective housing of the outer sprocket, therefore the tension should be adjusted only with bolts.

Methods for checking the degree of tension
To check the degree of tension, it is enough to pull the chain in the middle of the tire, the exit of the link shanks is allowed no more than 2/3.
- A normally adjusted chain does not have to jam when moving around the tire manually.
- Creak 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 bar and the protective cover.
After long-term operation, the chain is NOT tensioned due to the lack of adjustment travel of the tensioning mechanism. The constructional device of the chain allows its length to be reduced by removing several links. On the other hand, such savings results in a loss of chain smoothness and forced wear of the groove of the tire and the crown of the drive sprocket.
How to install a chain on a chainsaw
The chainsaw chain is the element that is exposed to the greatest stress and overheating. With such influences, it can break, fly off the guide rail, or simply become dull from prolonged use. For timely maintenance or replacement with a new one, you need to know how to independently remove the chain from the chainsaw and install it back. The step-by-step algorithm of THESE operations will be shown below.
Fitting the tire on Stihl and Husqvarna
Chainsaw models from the manufacturer Stihl may differ during the assembly process. Step by step guide:
- Open the wing nut, remove the chain sprocket cover. Return it on the tire all the way to the right.

In most models, the tension and adjustment of the position of the headset to the body is controlled by not one, but two wing nuts. A separate adjustment lever is rarely found on the protective housing of the outer sprocket, therefore the tension should be adjusted only with bolts.
Important! Before using the chainsaw, you should carefully read the owner’s manual. It describes in detail all the stages of setting up and assembling the instrument.
Tensioners
The classic budget-class chainsaw chain tensioner is usually a threaded bolt with an adjusting component, standard or side-mounted. The chain tension is adjusted with the included wrench or screwdriver.
expensive models are equipped with easy-to-use devices that allow you to tension the chain with one movement of the lever or turn of the adjusting disc.
In the first case, the degree of tension is fixed with a lock nut, in the second. The bar and chain tensioner are locked in position by installing the cover. In both versions, reliable fixation of the chain in a given position is guaranteed, the possibility of compensating for its extension with minimal loss of working time.
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 prerequisite 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 an incorrect position of the sprocket on the axis of rotation or a loose fixed saw bar on the chainsaw.
Why does the chain fly. Find out the reasons
When considering how to install a chain on a chainsaw, you should also pay attention to what reasons lead to its East. There are three main reasons:
- Incorrect bus operation.
- Malfunction of the main elements.
- Weak retention driven sprocket.
- Strong chain elongation.
Each reason becomes a prerequisite for which quite a lot of difficulties arise with the use of a chainsaw.
Chainsaw functions and device
In order to understand the features of the procedure under consideration, the chainsaw device should also be considered in detail. Among the features, the following points can be noted:
- The main part is represented by the engine. In most cases, a single cylinder structure is installed, since this is quite enough for cutting.
- The piston system is two-stroke, and the cooling is air. During operation, a small amount of thermal energy is released, so there is enough airflow to remove heat.
- As in many other designs, this one requires oil, which ensures the smooth running of the moving element. The oil is added directly to the fuel. Depending on the design, oil and fuel are mixed in the range of 1:20 or 1:50.
- The air filter can also be called an important structural element. Fuel is mixed with air to form a specific mixture, which is fed into the combustion chamber. If it does not constantly clean the filter element, then there is a possibility that debris will get into the cylinder block. This will cause rapid wear or even jamming of the device.
- A special design is presented as a starter, which is driven by a rope with a handle. If the rope is pulled strongly, then the flywheel is set in motion.
- The main operating mechanism is a splint with a buckle. It is designed to guide the chain and secure it.
- The classic chain consists of three teeth: leading, cutting, connecting. The fastening of the cutting edge is carried out using rivets.
A fairly common situation is the case when you have to pull the handle for a long time. It is due to the fact that the carburetor does not mix fuel with air correctly. In most cases, it is sufficient to configure the device in accordance with the operating characteristics. The chainsaw will last a long time if not properly maintained.
How to properly put the chain and tire on the chainsaw: assembly
The procedure under consideration is quite simple. It is characterized by the following features:
- First, the chain brake is released.
- The tensioning screw is in close proximity to the tire.
- The next step is to pull the cutter clockwise.
- If it becomes difficult to move the chain, then it is necessary to loosen the fixing screw.
Modern designs of chainsaws greatly simplify the conduct of such work. Therefore, you can do it yourself, even in the absence of Special tools.
Bus problems
Today, the problem associated with an unreliable fixation of the tire is often encountered. It is characterized by the following features:
- The body with the guide element is fixed with a bolt.
- The connection is provided by two plates, one of which is located on the body, the second on that, which is designed to guide the chain at the time of operation.
- The drive sprocket and the tire support are protected by a special casing, which eliminates the possibility of damage to the main elements.
- When the locking bolts are loosened, the structural element in question begins to move and vibrate at the time of operation. This problem can be solved by tightening the fasteners.
Other defects simply cannot be solved. In most cases, defects become a prerequisite for purchasing a tire and replacing it.
Circuit voltage
Stretching can be done using two methods: fast and frontal. If stretch is used, then the installation of the chain on the chainsaw is carried out as follows:
- The nuts are unscrewed.
- The tire is held and lifted from the edge.
- There is a special bolt, which is used to tension the chain.
- The tire is lifted to eliminate the possibility of sagging of the web.
It is quite simple to do this work, it requires a small set of tools.
The clockwise chain tension is carried out in the case when there is not a lot of free time. The chain screw is securely fixed to eliminate the possibility of rattling at the time of operation.
How to put the chain on a chainsaw correctly
To perform a sufficiently large number of works, a chainsaw can be used. The main cutting element of such a tool is represented by a chain with different blades. Modern versions are characterized by the fact that they can be serviced independently. When cutting for a long time or if basic recommendations are not followed, the cutting edge wears out quickly. That is why it is necessary to remove and sharpen the chain, and then install it. This procedure is characterized by a fairly large number of features, in which we will talk in more detail below.
