Why does my chainsaw chain keep coming loose?

Why does the chain keep coming off the chain on my chainsaw? The main reason for chain breakage is wear on your chainsaw chain bar. If you notice that many of the cogs are bent, it’s time to buy new cogs. The next most common cause of chain slack is poor chain adjustment or improper chain tension on the sprockets.

It’s important to keep the chain in proper condition, because over time, chains wear out and lose some of their optimal performance.

A loose chain is a problem that can be solved in a few minutes, but it is not a long-term solution.

It may take time to properly diagnose the chainsaw before recommending a solution. Problems can be more problematic than repeatedly loosening the chain. It may take the help of an expert to figure out why these chains keep tearing before figuring out how to fix them completely.

A chainsaw is one of the most powerful tools in a woodworker’s arsenal. It has many uses, but this article focuses on how to prevent chain breaks when working with it.

Another reason chainsaws chains fall off the bar is due to improper installation. Every time a chain tensioning procedure is performed, a final adjustment must be made to ensure that the chain tension does not change.

5 Reasons chainsaws always fall off the bar

One of the most common causes of chain slack is improper chain adjustment.
When adjusting the chain tension, you need to adjust it so that the tension does not change while the saw is running.
Some chainsaws have an automatic tension adjustment button, usually with one or two bolts.
These bolts are used to attach the rod to the inner sprocket.
If the sleeve nut caps are not tightened properly, the bar can become misaligned and the chain tension can be compromised.
If you store your chainsaw chain in a cool place before you use it, you may find that the chain needs some time.
Unless you live in a very hot or very cold place, you may not realize that your chain is the cause.
Temperature fluctuations here can have a significant effect on the tendency of your chain.
This is one of the most dangerous reasons why your chain can come loose.
On the other hand, chains have teeth on the drive rods that help the chain run straight.
To check the chain or rods for damage, remove the chain, rods and chain guard.
Check for any residue around the bars to make sure they are not worn. If so, you will notice that the screwdriver has become shallow.

When lengthening the chainsaw chain, pay attention to the drive links. If the drive link is intact, everything should be fine. However, if you notice a small gap between the links when extending the chain, it means that the chainsaw is set to full tension. Dry or dirty chainsaw chains can be a dangerous problem for homeowners. Chainsaws are great tools for pruning trees, but they can be difficult to maintain. So if your chainsaw is very dirty from prolonged use or you notice the chain getting dirty more than once a day, it may be time to replace it.

How do you tighten a loose chainsaw blade?

But before we get to that, let’s say that when you use a chainsaw, the chain inevitably stretches and therefore loosens after a while. We’re willing to bet that you don’t want to see a loosened chain blade. This is because it is often dangerous for carpenters. So in many cases, you need to check the chain stretch to determine if it needs to be repaired or not.

Most importantly, keep in mind that you can’t make repairs if you don’t know anything about proper tensioning. Lack of knowledge about this important aspect of the machine means you’ll end up with either a very tight chain or too loose to do anything about it. At this point, give us a quick overview of what chain stretching and proper tensioning looks like.

Poor/wrong tension.

You can check to see if the chain is loose by pulling on a screwdriver rod. Chains that come off the rod easily should be tightened immediately. You should also check the drive links. If they are loose, it’s time to adjust the chain tension.

Repairing constantly loosening chainsaw blades: basic steps to follow

First step:

First, the chain and drive link must be loosened before adjusting the heat. If the chainsaw brake is attached to two pieces of the side frame, begin removing the brake before removing the side frame.

Step 2:

Now it is time to adjust the tensioning screw on the drive rod side. Tightening the screw increases chain tension. Loosening the screw, on the other hand, loosens the tension and the chain.

The chainsaw chain is part of the blade that cuts the wood. Over time, the chain can stretch slightly during use. This reduces the performance of the saw, slows down the cutting process, and requires the user to put more pressure on the saw. If the chain stretches too much, it may even separate from the rod.

Why chainsaws chains are always separated?

To paraphrase and use a technical term, the question is, “Why is my chain separating from the drive rod?

If your chainsaw chain is coming off the drive rod, it could be because the chain drive pinion is worn. Its function is to provide driving force for the chain and hence wear and tear.

Over time, a wheel with tired teeth will not be able to maintain the desired chain breaking force and will not be able to hold the chain in the ideal position. If this applies to chain saws, you should expect the blade to continually knock the chain out of its groove when used for sawing wood.

Improper chain positioning

Although some chainsaw models are equipped with an automatic tensioning button, in most typical models one or two bolts are sufficient to do the job. The action of these bolts is to attach the rod to the inner gear wheel.

This ensures that the tension functions evenly. If the coupling cover nut is not tight against the screw, the bar position will shift, damaging the chain tension.

When the chain tension is adjusted correctly, many positive things happen with the SAW. Performance is improved, and the life of the motor, chain and rod is increased.

A properly tensioned chain on a chainsaw should still be slightly loose on the chainsaw drive rod, but the chain should be taut enough not to pull the pivot out of the nose of the rod.

Tension the chain before using the chainsaw

For a chainsaw to work properly, you need to recheck the chain every time before using the machine. But how do you know when to tighten the chain and when to loosen it? Understanding this requires a basic knowledge of different chain positions and situations. Basically, there are three situations in which a chain can It’s three chainsaw chains!

It is not tensioned enough;
The chain is not tensioned enough;
The chain is not tensioned enough.

To determine if the chain is properly tensioned, tension the chain and check how well it is attached to the base. If the chain looks loose and comes off without effort, it is not tight enough. A stretched chain will not be sufficiently tensioned during operation. In addition, the chain may break at any time during operation, causing serious injury to the operator or others.

Excessive tensioning

If the chain tension is ineffective and the chain sits tightly on the rod, this is bad because the chain is over-tensioned. An over-tensioned chain will not function properly because it is very tight against the tire. This can have a negative effect on the steering wheel, making it difficult to steer the chainsaw.

Overstretched chains sometimes stick. The situation becomes even more uncontrollable when the machine is running at high speeds. The chainsaw can even stop abruptly in the middle of work and get stuck at a certain point. This can cause serious damage to the chainsaw’s mechanical parts and even an unexpected explosion.

Tightening the chainsaw chain is not difficult, but doing it every time is not the most pleasant thing to do. If your chainsaw chain is hardened, it can be another problem.

What to do if the chainsaw chain is too tight?

Most chainsaw users are more concerned about whether the chain is very weak than very tight. And frankly, I understand the logic. It’s much scarier to think that your chainsaw might break than it is to think that your chainsaw chain is very tight (because of very little tension).

But in fact, a more common problem is that chainsaws are very tight, as opposed to very relaxed. It’s easy to lean conservatively, especially if you’re relatively inexperienced with chainsaws, which often leads to excessive chain tension.

This section provides a quick guide to controlling chain tendencies and ensuring that you are in the “golden ratio zone” (i. E. Not too tight and not too relaxed, but just right).

How to use voltage testing to monitor chain tension

To make sure the chain is tensioned properly, you can do a tension test after the tensioning is complete. All you have to do is gently pull the chain away from the chainsaw rod.

Pull the chain without losing the handle with your fingers (be careful not to cut it!). If the chain is fully stretched, it will partially detach from the rod, but the drive hinge will not detach completely from the rod.

On the other hand, if the chain cannot be lifted off the bar at all, the chain is definitely very tight. On the other hand, if the drive is completely detached from the chainsaw rod, it is very loose.

A loosened chainsaw chain will constantly tear, that’s a fact, and the question arises, “How do you tighten a loosened chainsaw chain?”. Raises the question. As mentioned above, the DIEM method is the best way to tighten chainsaw chains.

Precautions to take if your chainsaw chain is constantly loosening

The first and most important consideration for any carpenter using a chainsaw with a potentially falling blade should be its safety. There is always the constant risk of tearing the chain or snapping. There is the risk of losing an arm or a leg. So if you are aware of this problem, you make it easier to step up and find a long-term solution.

There are a few rules to follow when working with this powerful equipment. These rules remain relevant regardless of whether you are using an electric or gas chainsaw. Always remember the following:

Hold it steady: When using a chainsaw, always keep both hands on the chainsaw and your eyes on the rod of the chainsaw.
Drawing kerf: It is recommended that you draw the kerf so that the screwdriver does not protrude from the end point. If the screwdriver slips out of the end point, there is a serious risk of cutting your leg or foot.
Protective equipment: every inch of your body must be covered when using these devices. Therefore, always wear gloves, a hat, goggles, headphones, and boots. If the blade falls all the time, the situation can get worse.
Reducing impact: pay attention to the impact area to prevent the chainsaw rod from popping out. To reduce the risk of injury to the novice carpenter, you should choose a chainsaw with a reduced kick zone. You may have to endure its slow kickback, but better safe than sorry.
Reduced performance: Always be aware of how you are sawing with the chainsaw, especially when you are sawing from above or below. It is advisable to be even more attentive to the pull action when you are looking at the wood below. Similarly, always pay attention to the pull action when looking down from above, which ensures safe operation.
Correct posture: The safer right-handed position for right-handed people is to stand with the left foot in front, usually at a 45° angle, and the right foot behind. Keep your feet shoulder-width apart and bend your knees slightly.

Use a screwdriver on the end of the wrench to turn the tensioning pin

Loosen the screw on the side of the chainsaw to tighten the chain. Insert the wrench and the end of the screwdriver into the flat-head tensioning pin (chain tensioner) and tighten the chain clockwise. The chain cannot be tensioned otherwise. Turning the tensioning pin slightly pushes the chainsaw rod out and eliminates chain looseness.

Standard daily sawing for two to four hours may require re-setting the chain two or three times. However, this happens quickly and easily. This is because there is no need to disassemble the saw. Keep a wrench close by for tightening.

Fixing a chainsaw chain that keeps coming off is not difficult, but the problem may be more serious. This means looking deeper, diagnosing more than just a worn tire heel. So, another question that comes to mind at this point is what to do if, despite fixing the lost blade/chain, nothing happens.

Tighten the side panel of the screwdriver

It is very important to lift the nose of the chainsaw while tightening the nuts securing the side panels and screwdriver rod (see image below).

This is much easier if you know how to do it – just tighten the screwdriver rod and side panels! The chainsaw chain is now fully tensioned.

Keep your chainsaw and chain in top condition. Our parts service and information on power tools and equipment will help you get the most out of your equipment investment.

If your chainsaw is constantly running on the throttle and the chain is turning at high speed, the drive rod is strained to the limit. In this case, there is a good chance that it will accidentally shift in an unwanted direction and hit the ground, damaging it.

Frequent Questions

You can check by pulling on the chain to see if any part of it has come out of the slot of the screwdriver. You can also tell if the chainsaw is loose if you have to push the chain loudly before you start cutting.

This depends on how often the chainsaw is used. For example, in four hours of continuous use, the chain should be tightened up to three times.

Smoky chainsaws can be the result of extra pressure being applied to the drive rod for cutting. A loose chainsaw chain can cause the drive rod to apply more pressure and the chain will begin to smoke.

Remember that a loose chainsaw chain is a common problem that can be fixed in seconds. However, a loose chainsaw chain can lead to serious injuries that can be avoided. Understand the cause of the problem and find the right solution.
