Why the chain on a chainsaw slackens

Why chains for chain saws pull quickly?

A quick check of chain tension is very simple: you have to grab the prong and pull it up. If the chain is tightened properly, the tail of the chain will be pushed 1/3 of the way into the bar groove. A higher value indicates excessive tensioning, and a lower value indicates weak tensioning.

The chain should normally run smoothly along the guide bar and not exert excessive force. If the movement of the element is difficult. this is a sign of its excessive tension.

If the chainsaw’s cutting element is under too much tension, the bar begins to heat up and wear down, increasing the load on the engine and it quickly wears out. Do not operate the machine if the chain is loose, because when you are sawing it can get caught and break, endangering the machine operator. The chain can come off the bar and injure your limbs, and it often damages itself and the bar. Also, working with a loose chain element leads to one-sided wear of the bar, after which the unit ceases to make a straight cut, and the saw is pulled to the side.

Partner chain saws. Troubleshooting

Like other engine-equipped appliances, Partner brand chain saws need to be repaired from time to time. This can be due to improper use of the saw, or with the banal wear and tear of parts. No matter what it is, a chainsaw needs to be repaired, and it can be done with your own hands.

How to fill a Partner chain saw?

As the manual indicates, to fuel your Partner chain saw, you must use gasoline of at least the AI-92 grade. It must be mixed with oil designed for 2-stroke engines.

The optimum ratio of gasoline to oil for the Partner chainsaw is 50:1, which means that 1 liter of gasoline should be diluted with 20 ml of engine oil.

How to set the ignition on your Partner chain saw?

If you can’t figure out why your Partner chain saw won’t start, start by checking the ignition system on your tool. Checking and adjusting the gap looks like this:

  • First remove the cover that holds the starter motor. To do this, we recommend using the T27 hexagonal bit, tools from the chainsaw kit and additional attachments;
  • Carefully inspect the ignition coil, flywheel with magnets, and especially the clearance between these parts. To do this, use a specially designed gasket;
  • Setting the ignition on your Partner chain saw is accomplished by turning the screws, which brings the coil and flywheel closer together.

How to remove the clutch on a Partner chainsaw?

Repairing the clutch is often necessary if your Partner chain saw starts and stops when you accelerate. However, not all novice gardeners know how to remove the drive sprocket from a Partner chainsaw. Do this in this order:

  • First turn the lever and remove the saw chain brake cover;
  • Use the wrench provided with your Partner chain saw to loosen the clutch system nuts;
  • Remove the clutch from the chainsaw and completely disassemble it. If necessary, replace worn parts and clean the walls of the standard clutch elements.

How to Change the Oil Pump on a Partner Chain Saw?

If you find that the chain on your Partner chain saw does not turn, then the cause of the problem is likely to be a worn or broken separate pump designed for pumping lubricant into the chain. The oil pump consists of 2 elements. the storage chamber and the working part. Repair the pump is done with disassembly of the mechanism, but it is not recommended to take any action with the working part of it. The next steps are as follows:

  • Carefully inspect the inlet and outlet tubes through which the lubricant flows. as a rule, all pump failures are related to them;
  • If the channels are clogged, all debris must be removed. blowing them out with compressed air at the same time;
  • If there are cracks in the channels, they must be replaced;

If after reassembling your Partner chain saw the lubricant fails to flow to the saw chain again, then the pump will need to be completely replaced.

How to Adjust the Carburetor on a Partner Chainsaw?

The carburetor adjustment procedure for Partner chain saws is a little different from that for other brands. The differences are in the markings and values of the adjusting screws. Your Partner chain saw is equipped with three screws for adjustmentthe left fuel quantity screw, the right fuel quality screw, and the “T” idle speed adjustment screw. All of these screws are located on the left side under the top cover of the chain saw. Adjusting the carburetor on a Partner chainsaw is as follows:

  • Remove the cover and clean the parts underneath;
  • Turn both screws clockwise all the way out and then turn them 1/5 of a turn in the opposite direction;
  • Start turning the clutch pedal slowly until you feel that the engine is running at the maximum rpm possible. Immediately afterwards, turn this screw ¼ turn the other way. As a result, your Partner chainsaw should hold steady at idle speed;
  • Then, by means of the quality screw, set the maximum revolutions for the Partner chainsaw.

The tensioner structure and principle of operation

To tighten the chain on a chainsaw, there is a special device. The complexity of the construction of the mechanism is due to the cost of the tool and its budget category. On inexpensive models, the chain tensioner for the chainsaw is a bolt with a regulator on the side.

You can make adjustments with a screwdriver or special tool. The tensioning key is included in the kit for the work. It consists of 2 parts: on one side is a tool to unscrew nuts, on the other side is a slotted screwdriver. The more expensive models have an adjusting tool like a lever or an adjusting wheel.

The chain doesn’t fit the other components

Your chainsaw has a few operating parameters. One of them is the width of the groove for mounting the right chain. This width is available in several sizes: from 1.1 to 1.6mm.

To give you an example: for a 1.3 mm guide bar, we installed a 1.1 mm consumable. At first time and with a strong tension we will not notice the difference, but as soon as the tension loosens, the gap will not allow the chain to move evenly. We get the saw’s convergence to the side and the curvature of the cut.

It’s better to buy a chain if you specify its exact size, brand and model right away. The consultants at the stores know what width and pitch are needed for this machine. Or you can google your chainsaw, that’s all you need to know.

How do you know if the chain teeth are blunt?

You can tell at the beginning of a problem if the teeth are not as sharp as they should be. It is enough to pay attention to several important factors. Among them:

  • Increased physical effort required to perform standard sawing operations.
  • Sagging, chain stretching.
  • You feel a great deal of vibration when you’re sawing, the tool begins to slow down.
  • Sawdust changes its appearance after sawing, becomes finer, the work is no longer accurate. Roughness appears, edges become too sharp.

Experts say that well and timely sharpened teeth are much more important than the power of the tool. Without this, a model with any capacity will not work well.

How to avoid

To avoid saw headset loosening and breaking, use quality metal links. Check the chain for grease before use and systematically retighten the adjusting screw. Read more about how to start your chain saw correctly. During routine maintenance, keep an eye on the condition of the drive sprocket, which sometimes causes breakage.

To shorten or replace a chain link in a chainsaw you can do it at home. It is not a good idea to buy expensive riveting equipment. The procedure can be done with simple locksmith tools. The length of the headset and its tension directly affects the performance of the work, the risk of injury. Before starting the saw, you should check the tension of the blade, if necessary, tighten the adjusting bolt.

chainsaw faults. troubleshooting with your own hands

A chainsaw is a very useful tool at home. After all, with it quickly and relatively easy to solve a lot of tasks home construction, gardening and landscaping. A chainsaw is a rather capricious tool, but if properly handled, it is an indispensable helper.

That has one weak spot: the guide bar. It is the chainsaw that is responsible for most of the operating loads.

This means that knowing why tires are more likely to fail than other chain saw parts and how to properly replace them when necessary will help you save money and time during seasonal or project work with your tool more than once.

The chainsaw would not start

If you have trouble starting your chainsaw, many people immediately blame the carburetor. In fact, there are several variants, and the cause of malfunction can be anything:

  • The air and/or fuel filter is clogged. The problem can be solved by cleaning filters.
  • Lack of fuel in the tank. Yes, it happens and such reason. some owners forget about such insignificant detail, as a filling gasoline saw and think that a couple of liters of gasoline enough for six months. In addition, the fuel in the tank should not be stored for more than 14 days, i.e.к. gasoline evaporates and loses its octane rating.
  • Check the pipe from the fuel tank to the carburetor. it could be clogged or broken, so no gasoline is flowing into the tank.
  • No spark on the spark plug. Why the spark stops. there may be many reasons: no contact, the spark plug must be replaced or the spark plug is clogged. Why does the gasoline spark plug get stuck on the chainsaw? But if it happens, you need to dry and re-install it, and then check for spark. If the spark plug has a heavy deposit on it, it is advised to change it.
  • Check the muffler for carbon deposits. If there is soot. thoroughly clean the muffler, but it is still recommended to take the chainsaw to the service center to check the cylinder and piston there, t.к. Fouling is a sure sign of improper operation of the elements of the cylinder and piston group.
  • The carburetor is clogged. How to properly adjust the chainsaw, so that the carburetor worked well, was considered in a separate article.

If none of the above methods helped, then the cause is more serious. the failure of one of the nodes of the connecting rod and piston group. If it is too badly burned, you should still take your chain saw to a service center.

The engine stalls

The engine starts but stops when idling or under load. In this case, it is often necessary to perform the same actions as described above.

How to adjust the chainsaw depends on when problems occur:

How to determine the size and pitch of the chain

There are three important parameters that are the same for chainsaws and electric chainsaws:

Table 1 shows the distance between the rivets, which will allow the owner to correctly determine the chain pitch. In addition, in the manual to the original electric saw or chain saw will necessarily be specified pitch, length, number of chain links.

The total length of the chain depends on the exact number of teeth on the inside. You need to calculate the number of drive links, this will be the chain length.

Example: For a 40 cm bar you can use chains with different numbers of teeth, e.g. 57, 56 or 55. The number of teeth depends on the model.

It is a mistake to think that all 40 cm long bars can be fitted with the same chains.

It is also important to know the thickness of the shank (drive link). The shank holds the chain on the bar. To understand how to measure the thickness of this part, see Table 2.

Table 2. Shank thickness.

For non-professional chainsaws, the most common chain pitch is 0.325″. These chains are ideally suited for chainsaws up to a power output of 2500 Watts. To select a chain it is better not independently, and with the help of the seller or the expert, which work with accessories to chainsaws and electric saws.

Why does the chain on a chainsaw come loose??

An experienced chain saw operator who knows his trade well checks the tension of the chain and the amount of sharpening of the chain saw teeth before starting work. If you do not pay attention to the condition of the tool, its performance in the course of work is greatly reduced.

Proper chain tensioning will extend the life of the chainsaw and also keep the chain from slipping off the guide bar while you are sawing.

Chain tensioning is very important for chainsaw performance. If it is not properly tensioned, it can easily get damaged or slip off the guide bar while you are sawing. On the contrary, if the chain is tightened too much, there is more pressure on the tool motor. This greatly reduces the life of the chainsaw as it begins to wear out much faster. The chainsaw chain has another important function: it holds back the bar, which moves in different directions when idling.

How the tensioning procedure works?

To check the tension in the chain, pull the chain upward by grasping the bar nose at the middle or end of the bar outside. If the tension is set correctly, the chain saw will have 1/3 of its tail in the guide bar groove. If it is too tight, the chain is too tight and if it is too loose. The free movement of the chain on the bar is important. This is easy to check by trying to turn it by hand.

The tensioning process is not laborious, you just have to understand the order of all the necessary actions and pay enough attention to this procedure.

Before you start, make sure the saw is not running and that it cannot be started accidentally. Wearing protective gloves, twist the chain around the axis of the chain with your hand. If it is too loose, there will be a large amount of slack in the back of the bar. This is the factor to look at when checking if the chainsaw needs adjustment before starting work.

The Hidden Chainsaw Killer : Chain Stretch. Correct Way To Adjust The Chain Tension On Your Chainsaw

The first thing to do is to inspect the tensioning mechanism located on the right side below the side cover that secures the tool’s axle. This mechanism is most often a simple bolt, but in some cases chain saws are equipped with a special tensioning system where no additional devices are needed.

After that, you have to loosen the fasteners on the side of the chain to fix the guide bar. Next, use the adjustment screw to find the right tension by moving the axle forward. To check that the chain runs smoothly, turn the chain more often in the direction in which it is moving during operation.

After adjusting the chain with the tensioner, you need to tighten the bar ties securely. If the adjustment has been made correctly, the chain should move smoothly. It should not jam and should have a certain amount of inertia.

A wrong adjustment will cause the chain to stop suddenly and get stuck at times. Note that this is when the tension is too great. Because it has more of a negative effect on the tool, it is always better to adjust the chain with a little slack.

To extend the life of the chainsaw, it is recommended that this adjustment be made as often as possible.

Remember that it is not permissible to tension while the saw is hot.

The chain compresses after cooling down, so if it is too tight, it can pull on the bar and deform it, causing irreparable damage to the tool. Always allow the chain saw to cool down before continuing with the adjustment.

Diagnosing and Caring Properly for Your Chainsaw

Your chainsaw’s performance depends on a number of factors:

If the degree of tensioning affects the performance of the chainsaw, then the sharpening of its teeth #8211 affects the speed of cutting. This is why it is important to pay special attention to this point. A good tooth sharpening results in a much more efficient, precise and safe sawing process.

There are no specific guidelines on how often a sharpening should be performed, but professional sawyers recommend several times a day. This is because the teeth dull quite quickly when cutting extensively.

Most chain sharpening is measured relative to chainsaw performance. A tool also needs sharpening when the tire starts to run to the side. Another measure of sharpening is the condition of the shavings. as a rule, a properly sharpened tooth will make the chips homogeneous. The sawdust is rectangular or square in shape. In the case of a blunted chain, dust will predominate in the shavings, and the sawdust will resemble the shape of a needle from a simple hacksaw.

If you regularly check the tension in the chain and sharpen it in time, the chain saw will last a long time. Even particularly hard wood is no problem at all when sawing.

In case of insufficient experience, it is recommended to consult a specialist. Professional woodcutters determine the condition of a chainsaw and its components upon first inspection. They will determine how worn the chain is and if the tension is too tight or the sharpness of the teeth.

How to properly tighten a chainsaw chain? The answer is !

Dear customer, due to unfavorable currency exchange rates, please, consult our managers about prices. Thank you for your understanding!

If you look closely at the work of a professional woodsman who spends almost all his time in the woods with a chainsaw, you will see that he will never start the saw until he has checked the chain tension and the sharpness of the teeth. All of these are very important for productive work.

Tension of saw chain is a very important factor. A loose chain will wobble and might slip off the guide bar or even burst. Over tightening is also bad. it causes faster wear and increased stress on the saw’s engine. Also almost all saws are designed so that the chain tension also fixes the guide bar and the guide bar runs free left and right when it is free.

Chain tensioning is easy, you just have to learn the procedure and do it regularly.

For your safety, make sure the saw is off and cannot start accidentally. Turn the chain a little by hand, preferably with special gloves, along its travel. If the chain is stretched, the sag at the bottom of the guide bar is immediately noticeable. It is the bottom hang that determines how much tension the chain is stretched.
