How to tension the chain on a Stihl chainsaw
If a Stihl (Stihl) saw falls into your hands, do not be afraid and nervous, because got one of the most reliable and high-quality options assembled from components created by one manufacturer at its own facilities.
Always wear protective gloves or gloves before tensioning the chain on a Stihl chainsaw or checking the tension. This will not only protect your hands from cuts on sharp teeth, but also keep them clean, since machine oil is difficult to wash and wash.
First of all, the Stihl chain tension is checked. If the chain sags (part of the internal teeth is visible), then tighten it. When relaxed, it will damage the bar and render the saw unusable. If the chain is motionless when the brake is released, then it is overtightened, respectively, it must be loosened.
Stihl offers two possible options for chain tensioning of the chainsaw, quick and frontal. Both are used for improvement in the process of work. It should be noted that it is forbidden to pull on an overheated chain. According to the laws of physics, it will shrink after cooling, and it can burst from overtension or damage the tire.
In the frontal version, it is necessary to unscrew the nuts and lift the edge of the chainsaw bar, on which the chain is installed. 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 must be tightened back.
A quick version of the chain tensioning of the Stihl chainsaw assumes the following: the tension 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 is lowered. This concludes the procedure. Stihl chainsaw models have some differences in chain tensioning rules, it is advisable to find instructions for the tuned model.
How to put the chain on your Husqvarna chainsaw
All safety rules described for the model above are the same for Husqvarna (Husqvarna) saws. Do not tighten the chain with the saw engine running. It is allowed to start work only after a complete stop and cooling.
Before tensioning the chain on a Husqvarna chainsaw, check if additional tension is required. It should be noted that new saw chains require more frequent tensioning. From time to time, it stretches during operation, so this operation must be carried out before each use, if necessary. Otherwise, it will be necessary not only to replace the chain, but also the saw drive mechanisms.
The first step is to loosen the securing nuts located on the clutch cover. The next step is to turn the adjusting screw 45 degrees. If the chain on your Husqvarna chainsaw is overtightened, turn to the left (counterclockwise). In the opposite case, the screw turns to the right. If a single tightening is not enough, the operation must be repeated. At the end of the procedure, tighten the nuts on the protective cap using a combination wrench. They can also check the chain tension of the chainsaw by hooking it on the outer tooth and pulling the chain along the guide in the tire.
How to tension the chain on a Stihl MS 180 chainsaw
The first thing a newly-made owner of a chainsaw has to learn after studying safety precautions for working with a powerful tool for setting it up. The next thing to do after reading the instructions is testing the work, and if the saw does not work correctly, then the likely cause of this is incorrect chain tension. Therefore, the question immediately arises. How to tighten the chain on a chainsaw?
Usually, manufacturers indicate in the instructions for the chainsaw how to do this, but if for some reason it got lost, or the device went without it, for example, by inheritance, then the text below will help you find the right answer.
Stihl’s tip Tighten the chain correctly!
How to properly tension the saw chain?
Most Stihl chainsaws are equipped with a side chain tension bolt that can be used to make instant adjustments. To do this, turn off the engine of the chainsaw, and loosen the screws securing the side cover.
Take a screwdriver and turn the tension screw to tighten the chain, while slightly pulling and pulling the chain along the guide bar; in this case, you need to take precautions so as not to injure your hand on sharp teeth, therefore, this operation is best done with gloves
A properly tensioned chain should not sag at the bottom of the bar, but at the same time you should not use too much force when pulling it.
Some Stihl chain saw models are equipped with a quick tool-free chain tensioner, see fig. 2. In order to tension the chain, it is enough to unscrew the large special thumbscrew by hand, thereby releasing the side cover and turning the black wheel by hand to achieve the correct chain tension. Then you should re-tighten the side cover of the drive sprocket with a special screw by hand and the saw headset will automatically self-align for work.
Before installing a new chain, it is imperative to clean the groove (groove) of the bar from dirt. The accumulation of dirt in the groove interferes with the lubrication process of both the chain and the entire saw set, therefore, an uncleaned bar and chain overheat during operation. The ideal tool for cleaning grooves is an ordinary screwdriver or other suitable tool.
Important! Tighten the chain when it is cold and never adjust a warm or hot chain! Excessive tension, when the chain cools and contracts, can cause serious problems with the guide bar and headset. Therefore, you should even slightly loosen the chain before starting work, for example, during drizzle.
Recommendations for the selection of the cutting part of the tool
Before buying an important element, you need to study the main indicators that characterize it as an integral part of the cutting tool:
- Groove thickness;
- Chain pitch;
- The total number of links.
Several main groups have been formed, combined with each other by parameters related to the chain pitch: 3/8 inch tracks are mounted on low-power saws, the groove thickness is 1.3 mm. The number of links depends on the length of the bus: there are 52 links for a distance of 32 cm, and 56 links for 40 cm. On saw models from 350 to 401 cm, do not put a 645 cm bar.
For the correct choice of a caterpillar for other models, it is necessary to study the parameters of a previously operated chain.
The original models are characterized by the highest performance. They are resistant to friction and operate under adverse climatic conditions. Saw chains for all brands of chainsaws contain 50 drive links, 3/8 pitch, 1.3 mm groove. Sometimes the choice of a chain involves the fulfillment of several conditions:
Chainsaw chain device.
- Accurate familiarization with the instructions for the chain saw;
- Knowledge of the characteristics of the saw chain;
- Counting the number of teeth;
- Study of the step size between several links.
The chain has 52 driving links, 1.3 mm groove for a 35 cm bar.
The 52-link electric saw has a 38 pitch, a 1.3 mm groove for 36 cm bars, and for 10 cm bars, the tool contains 72 links.
There are 3 types of Poulan chainsaw tracks. The 35 cm bar is equipped with a 52 link chain. The other two groups contain 56 and 62 links.
Russian products work with tires of 40 cm (with a step of 38) and 57 main chain links.
For tools operated in extreme conditions, caterpillars made of metal alloys are used, which give them special strength.
Chainsaw equipment with a special caterpillar part
Often, for the safe operation of the saw, you only need to take care of the serviceability of all the components of the mechanism. A correctly mounted track will prevent the possibility of injury, and its installation will not cause any special problems for the master.
When it comes to installing a chain, you should prepare the tool for the job in advance:
- Combination key.
The chain must be well sharpened, then the work will be safe.
Work will be safe if the chain is sharp and tight. However, it is not enough just to correctly install the chain on the chainsaw; you should regularly monitor the working condition of the track.
At the beginning of work, the saw bar is inspected: it is fixed with a cover on the clutch.
When replacing the chain, use a wrench to unscrew the nuts securing the chain sprocket cover. Do not release the tension on the chain brake at the same time.
To dismantle, move the brake stop to the side. Pay attention to the holes through which the chain is tensioned.
Move the guide bar on the left, touching the drive sprocket. The utmost attention is required from the worker: he makes sure that the teeth on the upper part of the chain are turned towards the sprocket. One part of the chain is attached to the driving part, and the shanks are fixed in the grooves of the tires.
The chain is tensioned by adjustment with a screw that is attached to the surface of the clutch mechanism. After mounting the cover, screw the nuts slightly. The guide bar is in the top position, and the nuts are attached completely. Check the free distance of the track on the tire. The drum should turn very easily as the chain slides over the bar.
Planing wood with a chainsaw tooth.
Installing the chain involves checking its tension after each threading session. A loose part slips off the tire surface and injures the worker.
Examine the tension with your hands, protecting them with gloves. In addition, new chains change their length during operation, so checking should be done very often.
Sometimes an important detail arises during operation: it is not possible to install the chain without additional heating and its corresponding deformation from the side of the lower part of the tire.
Why do you need a chainsaw chain?
The assortment of cutting tools is huge, so it is necessary to purchase the best specimens for comfortable work.
The chainsaw is used in construction, when harvesting wood, for the improvement of summer cottages and adjacent territories. It is a versatile chain tool powered by a two-phase motor. Its cutting part is represented by a chain connected to a ring. Often, to create a rounded shape, it is composed of links that have different shapes. The chain is attached to a metal rail. Most models have a sprocket. The chain is part of the accessories for non-professional and special saws.
Professional chainsaws for sawing wood are equipped with 3/8-inch and 0.404-inch chains.
For hobbyist tools, chains with a 0.325 inch pitch are used. The size of the non-professional track reduces vibration, but also reduces the power of the tool.
High quality wood cutters are available with 3/8 ”and 0.404” chains.
Since the caterpillar is the cutting part of the chainsaw, its selection and installation must be approached with all responsibility.
Monitoring the performance of the electric saw track brake
To protect a working person from damage from a chainsaw, a braking device is used. With its help, the work of the tool is stopped until the tire hits the worker’s body.
The device of a typical chainsaw.
Stopping the chain depends on two conditions:
- Braking speed;
- Time of switching on the tool.
The saw is started using 2 methods: contact and inertial. To protect the operator from tossing the chainsaw, the brake is equipped with a shield against which the worker’s hand rests. Some saws have protective strips that mask the cutting edge of the tool.
Track Tension Control on Saw
No working professional will ignore chain tension in a chainsaw. By pulling slightly on the track, it instantly estimates the amount of chain stretching. The sound that appears at the moment of impact can be dull and short.
The tension of the caterpillar is carried out sequentially, performing several simple operations. Inspect the fuel cock. The worker needs to make sure the fuel system is blocked. You can remove the plug wiring or open the decompression valve. The power saw plug is pulled out of the socket. The chain is turned in the direction of its rotation during operation.
The position of the file when sharpening the chainsaw.
Defects in chain tension are visually noticeable: lower sagging of the track is formed. Control is carried out by adjusting the circuit at certain time intervals. There should be a constant headroom at the top of the shank, generated by pulling on the chain. With very strong tension, the track barely turns and quickly stops its movement.
Adjustment of the chain in the working position is not allowed. Such negligence will deform the tire or break the crankshaft.
The track tension during operation is carried out without tools. The maximum cutting depth is 390 mm, the weight of the cutting equipment is 9.4 kg.
To prolong the life of the chain, tension is only made under favorable weather conditions.
With prolonged load on the power saw, use two circuits, alternating their work.
Installing and choosing the right chain for a chainsaw
Modern types of chainsaws allow owners to get the job done without much effort. The work will be done efficiently and in the shortest possible time if the chain is installed on the chainsaw in time and in full.
The chainsaw is used to cut wood.
To check the chain tension, the saw brake must be disengaged. Then manually pull the chain along the bus, if it runs smoothly and does not sag, then everything is fine. If the chain is very tight, then it needs to be slightly loosened, because there is a risk of rupture during operation.
Why the chain flies, find out the reasons
If you wondered why the chain on your chainsaw flies, then there is some kind of malfunction in the mechanism. Exist three main reasons This malfunction: malfunctioning bar, chain stretching and loose sprocket. Let’s take a closer look at each of the possible causes of breakdown.
Chainsaw device features
The main part of the gasoline saw is engine. In most modern devices, the engine is single-cylinder. Air cooling, two-stroke piston system. Oil in these types of engines is added directly to gasoline, and all due to the fact that the fuel constantly flushes the crankcase. The oil-to-gasoline ratio varies from 1:20 to 1:50 depending on the manufacturer of the chainsaw.
The air filter on gasoline saws plays an equally important role. He needs regular cleaning. If the filter is heavily contaminated, dust from it will fall directly into the piston system, leading to engine damage.
If the filter is clogged, the saw will lose speed and the engine will overheat, which can cause the piston rings to burn.
The starter on gasoline saws is a rope with a handle that you pull on to activate the motor. When you pull on the rope, the teeth catch on the ratchet, and the flywheel begins to spin.
Many people complain about the long pulling of the rope to ignite the engine. It depends on whether the carburetor is correctly aligned. If the carburetor produces the correct oil-gasoline mixture, then there should be no problems.
Main working mechanism tire with grip.
The chain consists of three types of teeth: leading, cutting and connecting. They are riveted together. The cutting teeth are located on two sides: right and left.
Chains are divided into two types: high profile and low profile. The first type includes chains, in which the teeth are located with a large gap, to the second with a smaller gap. Chains can also vary in shank thickness and link length. The chainsaw chain is attached to a bar that guides it in the correct direction. The end of the tire has a specific groove that holds the links and allows the chain to rotate. A driven sprocket is located at the front of the tire. The chain together with the bar is called a headset, since they are detachable parts of the chainsaw.
The gasoline saw has an automatic chain lubrication system. The tire supplies oil, which is then absorbed by the sawdust. If the saw is idling, the oil supply stops.
How to tension: installing the chainsaw cutting element
We have analyzed the main reasons for the sagging chain. How to install a chain on a chainsaw is described in the paragraph above. Now you need to properly tighten the chain, and check if it will overtighten.
Poor drive sprocket
One of the possible options for a dangling chain on your device leading sprocket problem. Most often, everything happens due to the fact that the star is poorly fixed. Now we will tell you how to properly fix the star and then put the chain on the chainsaw.
First you need to remove the engine protection cover. Next, remove the protective cover of the spark plug, pull out the air filter. Then you need to unscrew the candle with a special key. A special stopper is placed in its place, which fixes the piston in a certain position. With a special key (you can use a universal wrench for a grinder), turn the clutch disc clockwise until the piston reaches the uppermost position. Looking into the hole of the plug, the piston should remain at the bottom. A thick rope can be used as a stopper; it is better to fold it several times. Once locked, the drive sprocket can be clamped by rotating the clutch disc counterclockwise.
After clamping, you need to do everything in the reverse order, that is, assemble the chainsaw. A chain is put on the tire; it must hit the drive sprocket that holds it. The tire is placed in special mounting holes and bolted. Then the defense is placed.
The chain stretched
If your chain sags on a chainsaw, then this indicates a malfunction of some mechanism, one of the options is the wear of the chain itself.
Over time, the metal deforms and the chains become 0.5-1 cm longer. It is best to fix this problem by purchasing a new circuit, but there is a way to get the old one back. Experts say that this is very difficult and almost impossible, but we will tell you how you can do it at home.
For this we will need:
- Electric welding machine (not needed in all cases);
- A hammer;
A regular chainsaw chain is made of strong steel, so it is difficult to disconnect. You need to disconnect the chain on the inside of the rivet, which serves as a connecting mechanism.
First, the chains need to be fixed in a vice, and then gradually grind off the protruding part. You need to grind with a file or a file. It is not recommended to use a grinder, as there is a risk of damaging the lateral parts of the links. After sewing, the rivets are knocked out with a beard. The knocked-out rivet should not be thrown away. You may not be able to find a replacement. Manufacturers of gasoline saws do not produce individual parts for the chain, as they do not expect consumers to be able to repair the chain themselves. Most likely, you will not be able to make a new rivet yourself, so you will have to install the old one.
In order to shorten the chain, you need to split it in two places. But remember, that the number of guide lugs on the inside of the chain and the distance between them must match the drive sprocket.
After removing one or more of the links (depending on the degree of chain stretch), the chains can be connected. We connect to old rivets, while pressing them tightly on the sides.
Next, we need a welding machine. The rivet must be welded to the lateral parts of the link. After that, we grind off the excess that formed during welding with a file. The chain can be considered healthy again.
