Chainsaw Saws Crooked Reason
Why does the chainsaw go sideways?
It is worth considering the consequences that you have to face if the chainsaw does not cut well. If you, for example, are engaged in the preparation of wood fuel, then the curves of the finished chocks, due to the uneven surface, will complicate the process of breaking them into logs. If you are laying a log house, then curved bars cut with a saw, which go sideways, cannot be used, since the ends will be sloppy during laying.
But these are not the worst consequences, given the fact that the bus offset leads to:
- Imbalance, which means discomfort when using the saw;
- Decreased tool performance;
- Increased fuel consumption.
The tire also deteriorates, which cannot but upset especially those who have a premium expensive saw headset, which will have to fork out to replace.
So why the chainsaw saws crookedly, the reason is one or several?
- The saw teeth are unevenly sharpened;
- An unsuitable bar or chain was used (they work poorly together);
- The saw head is worn out.
If the saw head is incorrectly selected
Often, most sawers simply do not pay attention to the fact that not only the chain has technical characteristics, but also the tire and the drive sprocket with a crown. All these details must correspond to each other in such a technical parameter as a step. Most chainsaws are equipped with a headset with standard pitch parameters equal to 0.325. The tire, chain and drive sprocket, or rather the crown, must have the same pitch. If one of these parts does not meet one standard, then this will lead to accelerated wear of individual parts and the entire tool.
The tire also has such a parameter as the groove width. The value of this value can vary from 1.1 to 1.6 mm, depending on the power of the tool. It is categorically contraindicated to install a tire with a groove width of more than 1.3 mm on a household chainsaw. A standard chain in such a tire will have too much play, which will lead to accelerated wear of both parts.
Never buy an instrument headset if you don’t know or remember the exact measurements. A "like this" chain, bar or sprocket may be far from suitable for your tool, and as a result, you will need to change all consumables. To find out the width of the tire, you will need to use a caliper or look in the technical description for the tool.
Teeth are unevenly sharpened
Let’s consider the first reason. Those powertrain operators who have read the instructions carefully know that the teeth grind at the same distance. And it doesn’t matter which side they are on. Everyone who remembers this rule when sharpening saves himself from problems in the long run, from the problem of uneven cutting of wood material.
As soon as you notice that the saw is being pulled to the side, check the chain teeth. It is highly likely that it is an illiterate sharpening that is the cause of the problem.
Inexperienced chainsaw operators or those who use a file rarely control the length of the teeth. Even the notorious technique of counting movements made when filed a single tooth does not help. Why? Because the chain wears out unevenly, which means that on certain teeth it will take more or less file movements in order for the sharpening to be of the highest quality (all teeth were even).
How do I fix this problem? Learn to sharpen the chain correctly, do it on time. You need to get in the habit of checking the teeth for wear, and if damage is found, it is recommended to resort to using a special sharpener. You can really get this one yourself. It is these machines that are used in workshops, where for a certain fee the teeth of the tools will be made identical, one to one.
Why is this particular method effective? Because all sharpening will be done on the smallest tooth, the one that has been subject to wear. This ensures that each tooth will end up being the same.
If you want to learn how to properly operate a chainsaw chain, contact a professional. Or learn to sharpen the chain correctly on the machine.
There is, of course, one unpleasant nuance. It is necessary to take into account the fact that you grind on this device even those teeth that have not been damaged, and this leads to a decrease in the resource of the saw headset. To minimize the need for low-wear teeth sharpening, ensure that no metal parts such as nails fall under the chain when working with wood (this happens with old boards).
How to fix chainsaw tilt while cutting
To understand why it takes the chainsaw away during sawing, you need to understand a little theory. Knowing the theoretical points will make it possible to fix the problem with minimal cost, since most often the problem can be solved. So why is the chainsaw drift??
What to do if the chainsaw is pulled to the side when cutting
Knowledge of the above theoretical points allows you to determine ways to prevent and eliminate this phenomenon:
- Sharpen the saw regularly. Using a special machine.
- Always check the correct saw chain tension. In this case, it is necessary to follow the above recommendation.
- Straighten the tire in case of deformation of its sides.
The main reasons why the chainsaw is misdirected
If the chainsaw starts to cut crookedly during operation, then besides an uneven cut, we get a number of the following negative consequences:
- The sawman needs to exert physical effort to keep the tool in a straight direction.
- Fuel consumption increases, which is associated with an increase in the trajectory of the tool passing through the material being cut
- Increased load on the drive sprocket, which leads to accelerated wear
- The tire wears out as the load only increases on one side
- Decreases tool performance
- Obtaining a cut curve. If the forest is being prepared for the manufacture of boards, then crooked trunks are equated to marriage. If the tree is cut for firewood, then in the end, the curved-sawn log will not be very convenient to chop
- Discomfort during work. the master gets tired quickly, working with a faulty tool
Why can a chainsaw cut trees crookedly? Many people may think that the reason is a malfunctioning chainsaw tire, but in fact, there are four main reasons:
- Incorrect or uneven sharpening of teeth
- Using a chain, bar or sprocket that does not match in pitch
- Saw head wear. often due to abrasion on one side of the bar
- Untimely tightened chain
If this kind of malfunction occurs, such as an uneven cut in wood, then it is necessary to resort to its elimination as soon as possible. If you continue to operate the tool with such a malfunction, this will lead to engine wear and the need to repair it.
Let’s consider each type of malfunction separately, and find out how to determine what is the reason why the chainsaw is sawing on its side.
The chain is breaking
If the chain broke during the operation of the chainsaw, then this could happen when it hit a hard object, for example, a nail. If the chain is constantly breaking, then the reasons may be as follows.
- Saw chain metal is of poor quality. It is necessary to buy saws for gas cutters from well-known brands.
- Overheating of the chain due to poor lubrication. As a result, the saw overheats, the properties of the metal change, and it breaks under load. It is required to check the entire chain saw lubrication system (discussed above).
Also, you can learn about the reasons for frequent open circuits from this.
Chainsaw engine malfunctions
The engine is the main unit of the chainsaw, and most of the breakdowns that occur in it are associated with the gasoline drive. Correct diagnostics can determine the causes and remedies for malfunctions, even for an untrained user.
The main problems with starting the engine can be as follows:
- The engine will not start;
- It works unstable;
- A start occurs, after which the unit immediately stalls;
- Stalls under load.
Chainsaw chain problems
In addition to problems with the engine, the chainsaw may have operational problems due to a malfunction of the cutting (sawing) unit, consisting of an oil pump, a bar and a saw chain.
The tire is not getting oil
Usually, if oil does not flow to the chainsaw chain, it is required to check the channels through which the oil is supplied to the tire and clean them of contamination. If the previous steps did not find the cause of the problem, then you will have to check the oil pump. For this you need:
- Remove part of the chainsaw cover;
- Remove the clutch;
- After unscrewing 3 screws, remove the cover that hides the pump;
- Reach the worm gear that rotates the pump shaft.
If the thread on it is worn out, then the shaft does not rotate, the pump does not work, the chain is not lubricated. A worn gear must be replaced. You can also pull out the oil pump itself and manually try to pump oil through it. If it does not pump, the pump should be replaced.
Chainsaw oil filter
Also, the lack of lubricant may be due to its leak. It is necessary to check how tightly connected the pipes coming from the oil pump. If the tightness is broken, the tubes are replaced with new ones.
The chain doesn’t stop
If, when working with a chainsaw, you notice that the saw chain does not stop at the right time, then this breakdown may have 2 options.
- The brake band is dirty. When the saw is in operation, dirt, sawdust, dust, etc. Can get under the belt. As a result, the brake mechanism is locked and the chain does not stop when the throttle is released. The problem is eliminated by cleaning this unit.
- The brake band is worn out. It is necessary to replace this element of the brake system.
Why is the chainsaw heated
The new chainsaw is heating up, because all the parts of the piston group have not yet worn down. Therefore, the unit must be run-in, during which the engine must not overheat. If the unit has already been run in, then engine overheating can cause late ignition, of course, provided that the combustible mixture was prepared without disturbing the proportions. To fix the problem, you will need to adjust the ignition system of the device.
