If your chainsaw blade will not rotate, the chain may be tensioned too tight. The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. 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.
why is my chainsaw blade not spinning Related Question:
Why does my chainsaw blade not turn?
If the chain is too tight, the blade may not spin when the throttle is engaged, which can cause damage to the clutch or other associated parts. Keep in mind that the tension of the chain will change with heat. As the chainsaw is used and the chain heats up, it will become loose.
How do you know if your chainsaw clutch is bad?
Does the engine loose revs, or the engine keep revving and just the chain stops? If the engine is still running at normal revs, and the chain slows down, then it’s a problem with the clutch. Worn out, gummed up, jammed springs etc. If the engine looses revs under load then it’s more likely a fuel or carb problem.
What does the clutch do on a chainsaw?
The clutch allows the engine to turn freely at low rpm [rpm=revolutions (turns) per minute] without moving the chain. They are separate. Unlike a four wheeler or truck, the chainsaw operator doesn’t have to engage the clutch or put the chainsaw in gear.
Why is my chainsaw jamming?
Here are our explanations! Indeed, whether it is a chainsaw electric ou thermal, it is the teeth of its links that come into direct contact with the wood and the materials to be cut. As a result, dirt, wear on the guide or links and even the motor can be the cause of jamming.
How do I stop my chainsaw from pinching?
Avoid standing directly behind the chainsaw to avoid injury from kickback. To prevent the trunk from splitting it is advised to make a cut a third of the trunk’s diameter. This cut should be made on the side of the trunk that is going to be exposed to the most compression.
Can a chainsaw without a chain hurt you?
Can You Run a Chainsaw without the Chain? You can run a chainsaw without a chain but try to do that just for a few minutes. I wouldn’t advise you to run a chainsaw without a chain for more than a few minutes. If you are not careful, you can overheat the engine and increase the wear and tear.
How can you tell if a centrifugal clutch is bad?
When heat damage occurs, the clutch will never disengage and the machine will start taking off by itself as soon as you start the engine. You can see heat damage inside the clutch drum, the metal turns from black to a blue color. The clutch must be replaced if it has heat damage and won’t disengage.
How do you know if your chainsaw sprocket is worn out?
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on.
Can you run a chainsaw without a clutch?
A clutch is an absolute necessity on a chainsaw. Without one, the chain sprocket would be connected directly to the motor, and the chain would turn even when the engine is idling.
What does a clutch drum do?
An outer drum that turns freely – This drum includes a sprocket that engages the chain. When the drum turns, the chain turns. A center shaft attached directly to the engine’s crankshaft – If the engine is turning, so is the shaft.
Can you over tighten a chainsaw chain?
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 many times can a chainsaw chain be sharpened?
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.
Do you start a chainsaw with the brake on or off?
Check the Chain Brake When engaged, the chain brake stops the chain from rotating around the saw’s guide bar. When using a chainsaw, you should always start it with the chain brake engaged so the chain does not move.
What does a spark arrestor do on a chainsaw?
The spark arrestor on your chainsaw prevents dangerous hot sparks from igniting fires while you’re working. If the arrestor is clogged or dirty, however, it will also prevent exhaust from leaving the motor, which can prevent it from running.
