The chainsaw chain should feel snug but still pull freely. Finally, perform a “snap” test to ensure proper saw chain tension. Simply pull the chain on the underside of the guide bar down so one or two drive links are out of the guide bar rails and release it. The chain should snap directly into position.
How tight should a chainsaw chain be?
A properly-tensioned chainsaw chain should still be just a little loose on the chainsaw guide bar, but the chain needs to be tight enough that you can’t pull the drive links out of the bar nose.
Can you over tighten a chainsaw chain?
This simple maintenance task is easy to perform and necessary to keep your chainsaw running safely. There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don’t over-tighten the chain as this could cause it to break.
How much slack should a chainsaw blade have?
It should “give” about a 1/4 inch from the bar without much effort. Finally, while still holding up on the tip of the bar, tighten the bar nuts. Proper chainsaw chain tension is safer, it cuts better and it will extend the life of both your chainsaw and your chain.
Why does my chain keep coming off my chainsaw?
Chainsaw chains come off the bar due to worn-out bars, worn-out sprockets, and wrongly set tension. You should also note that with continued use, chains lose their tension and hence are more likely to come off the bar when you least expect it.
How do I know if my chainsaw chain is tight enough?
The chainsaw chain should feel snug but still pull freely. Finally, perform a “snap” test to ensure proper saw chain tension. Simply pull the chain on the underside of the guide bar down so one or two drive links are out of the guide bar rails and release it. The chain should snap directly into position.
Why won’t my chainsaw chain tighten?
If you can’t tighten the chain, you may not be implementing the proper tightening procedure. To adjust the chain, loosen the nuts that hold the guide bar in place. Attempting to turn the tension screw without loosening the nuts first may be the reason you can’t tighten the chain.
Do chainsaw chains stretch over time?
It’s perfectly normal for a chainsaw chain to stretch after regular use. The friction from cutting through wood makes the chain very hot and the heat causes it to loosen. The heat expands the guide bar and when it cools, the chain has stretched. The chain will also loosen as it wears down from use.
How long do chainsaw chains last?
The lifetime of a chainsaw chain has no fixed limit and depends on usage and maintenance. The chain should last many years; 5-6 years should be no problem. However, if the chainsaw chain is used properly and taken care of, it can last way longer.
How many times can you sharpen a chainsaw chain?
Cutters can be sharpened up to 10 times or more before the chain needs replacing. If your cutters are worn unevenly after a few sharpenings, a professional can regrind them to uniform shape. If you use the same chain for a few years, then buy a new one, the new one won’t mesh smoothly with the sprocket and bar.
Why does chainsaw cut in a curve?
Two main reasons will cause the chain to cut on a curve. The most common reason is from improper hand filing. If one side of the teeth is more heavily damaged, sharpening them down will make them smaller than the other side.
Which direction does a chainsaw chain go?
The direction of the chainsaw blade is always the same regardless of the type or model of chainsaw. So the sharp edges of the blade should always face the clockwise direction. If you check from the top, you will notice that the sharp edges are facing the direction opposite the chainsaw body or motor.
What is the LA screw on a Stihl chainsaw?
The LA setting on Stihl chainsaws is controlled by a screw on the outer housing of the engine that adjusts the flow of fuel and air through the carburetor. This screw is inside the engine housing on the carburetor, but is accessible through a hole or gap in the outer housing of the saw.
Why does my chain keep getting loose?
Your chain might simply be too old or can stretch over time. When this occurs you need to replace it. Consider that your loose chain also may be due to operator error. Exceeding the recommended gear range for the rear derailleur on your bike may lead to a droopy chain when you ride in these gears.
What causes a chain to stretch?
Another highly significant factor in chain stretch is the accumulation of dirt particles between parts of a chain. These particles form a paste with existing petrochemical lubricants, and they will cause pins, rollers, and bushings to lose material rapidly, again resulting in an overall elongation of the whole chain.
How much do chainsaw chains stretch?
one eighth of a millimetre all round) then once you have pulled all of that clearance space to one side, your chain will be 17.5mm longer, that’s around three quarters of an inch.
Do chainsaw chains have a master link?
Locate the master link that most manufacturers install to make removal of the chain a simple process. A visual inspection of the chain will reveal the master link due to its appearance that makes it stand out slightly from the other links.
Why does my chainsaw blade go dull so fast?
With a single contact with the ground while running, a chainsaw can become very dull. This is because the ground contains sand and dust which is abrasive and contains a lot of tiny rocks. To avoid such occurrences, avoid cutting wood placed on the ground.
Is it worth sharpening a chainsaw chain?
