How to tighten a chain on a chainsaw: instructions and recommendations
Professionals know quite well thatthe very power of the chainsaw makes it a good tool, but how correctly it is used. With proper care, any chainsaw can last a long time, while demonstrating excellent performance. If on the contrary - not to look after the tool properly and not adhere to the rules of safe operation, it will significantly shorten its service life and lead to early failure.
One of the most important moments of correctTechnical maintenance is the care of chainsaw chain. You need to know how to tighten the chain on the chainsaw, how to properly grind it and lubricate it. It is also very important to have a good idea of its characteristics. This knowledge can be very useful if you have to choose a new chain.
Chain function and its correct tension
Correct position and tension of chain chainsawsIt is very important not only for its normal operation, but also for the safety of the person who works with it, as well as those around it. If the chain has an incorrect tension, then during operation it can accidentally fly off, which, most likely, will cause breakage not only of the chain itself, but of the entire chainsaw. However, it is undesirable even when the chain is stretched too tightly. This can also have negative consequences in the form of increasing the load on the motor, which in the future will lead to its rapid failure and reduction of the overall service life of the chainsaw. The chain has one very important property: it fixes the tire, which prevents its arbitrary movement. Therefore, care for the chain should be given special attention.
Correctly choose a chain
The failure of the circuit is a frequent occurrence, thereforeBefore you ask yourself how to tighten the chain on the chainsaw correctly, you need to know which chain is right for the given chainsaw model. The main criterion in choosing is its step. Step is the distance between its teeth. The distance it is selected between its nearest teeth and is measured in inches. The most common are 0.325, 0.375, and 0.404 inches. The step information can be found in the operating instructions for the particular chain saw model, and it depends primarily on the purpose of the tool.
Each saw has its own specific step,exceptions are only professional tools that are universal. The pitch of the chain also depends on the engine power. The more powerful the chainsaw, the greater its pitch and the more difficult it is to hold it when working. For example, the compact low-power chainsaw "Patriot" has a pitch of 0.325. However, there are more powerful models. One of them is the German STHIL in increments of 0.404. That, as we see, more than the chainsaw "Patriot".
Step - one of the most important characteristics of the parameterschain. This means that you should not choose a chain with a large pitch for a low-power chainsaw. It can not only not come up, but also put the tool out of action.
The Importance of Proper Chain Configuration
Normal operation of the chainsaw causes vibration,which can greatly weaken the tension of the chain with blades or nuts, intended for its fastening. The chain stretches during intensive use and is poorly fixed on the chainsaw teeth, which can create unsafe conditions for the operator. The proper operation of the tool involves checking all nuts and bolts before and during use to ensure safety. If the chain nuts are too loose on the saw teeth, you will most likely need to pull the chain correctly and then tighten the blade itself.
Before starting work, always rememberown safety and use protective leather gloves and goggles. Chainsaw should be placed on a flat surface, for example, on a workbench or table. The engine must be allowed to cool completely if it has been used before. Next, to prevent accidental starting of the saw, remove the wire from the plug of the spark plugs. Now you can start adjusting the chain.
How to pull the chain on the chain saw by own strength
It is not difficult to do this, the main thing is to rememberown security. So, how to put the chain on the chainsaw correctly? Stand in front of the chainsaw, facing you with a blade. Grasp the tip of the saw blade with one hand and lift it slightly. Firmly insert a flat head screwdriver into the adjusting screw that is to the right of the blade when you look at the saw blade. Turn the screw in the clockwise direction to increase the chain tension, or counterclockwise, to reduce it accordingly. Take the chain in one hand and pull it around the blade. The tension is correct when it is slightly loosened by pulling in the direction of the blade, and at the same time snugly adjacent to it.
If this is the case, then further adjustment of the circuit toA chainsaw may not be required. If not, then you need to adjust it. Loosen or tighten the adjusting screw to get the correct fit. Hold the tip of the chainsaw blade with one hand. Tighten both blade retaining nuts on the left side using the saw repair kit or the adjustable wrench. Place the spark plug wire back in place and press it firmly.
Required Tools
When buying chainsaws are often bundled with itthere is a tool for its maintenance. It is necessary to adjust the circuit. It has the following appearance: at one end there is a screwdriver with a flat head, and on the other end there is a screwdriver that comes to the blade nuts. To understand how to tighten the chain on a chain saw, refer to the operating instructions for this saw model.
Safety precautions
When using chainsaws, personal protective equipment should be used, including eye and hearing protection, leather gloves and hard hat.
For safety when working with a chainsaw, it is desirable to have another person close by, who will be able to help in case it is needed.
Chain sharpening
Everyone knows that from time to time we need Chainsaw Chain sharpening. However, not everyone knows how to do it right. A sure sign that the saw needs sharpening is the shape of the sawdust. If they look like fine dust, it means that the chainsaw blades have become blunt and need to be sharpened. When the chain is heavily worn, when it is no longer possible to sharpen it, it must be changed to a new one.
Chain sharpening methods
There are many ways to do this. As examples we give the most common:
- Sharpening using a file. Its convenience consists in its simplicity, because there is no need to use complex equipment and machines. In addition, this sharpening can be done directly on the job site, which saves time.
- Sharpening the machine. Most often it is used in equipped service centers or workshops, but it also takes place in a personal farm.
- Sharpening using a Bulgarian. One of the most difficult ways of sharpening, since it requires special skills. Because of this, this method is not widely used.
How to shorten the chain on the chainsaw
Chainsaw chains should always be in good conditiontechnical condition. All defects and malfunctions must be given the necessary attention. Follow the general safety instructions and recommendations in the operating instructions. Only in this way can you avoid injuries and other undesirable consequences when working with a chainsaw and extend its service life.
Sometimes due to wear, deformation or otherreasons to replace the chain or shorten it. It should be noted that the sagging of the chain does not mean that it needs to be replaced. You need to change it if it is not completely adjustable.
Sometimes in the process of intensive use the chaincan sag. This is due to a strong overheating of the metal, its expansion and, as a result, lengthening. An exit from this situation can be a periodic stop to allow the chain to cool. However, this is not always possible. Another situation can arise when, say, you need to install a chain, the length of which is somewhat large.
Tension adjustment
The tension of the chain must be adjusted using a tensioning bolt of the chainsaw, which is located in the place where the toothed stops are.
It is important to understand how the chain should be stretchedchainsaw. You do not need to pull it all the way, because soon it can stretch again. The chain should have a small supply, slightly sag. It's not hard to check by hand. It should be able to be pulled away by a millimeter from the tire.
It is best when the chain has a sufficient length andyou can delete several of its links. In this way, we can use the original links for chainsaw chain. They can be unfastened by a hacksaw for metal, but it will be much more convenient to do this with a sandpaper. To do this, it is necessary to unfold the link, piling it, and then cut off the part that is superfluous. Further we beat out rivets from those links which are not necessary, we delete them and we connect a chain independently. For this you can use special rivets, but if they are not available, you can use ordinary steel wire. We lay the chain on a solid base and begin to rivet on both sides.
