FAQs

 How does chain stretch happen?

Because the chain’s pitch lengthens as it ages, chain wear is also known as “chain stretch.” The rise in this sort of chain wear, which is the most significant, results from the bushings wearing alongside the chain pins. These bushings’ inner diameter grows over time, and the pins develop outward grooves.

 What occurs if the chain of a chainsaw is too slack?

Chainsaw kickback and chainsaw chain being thrown off the guide bar are both more likely to occur when the chainsaw chain is loose. Too-tight saw chains can prohibit the chainsaw from turning or result in the chainsaw heating.

 Why is a stretched chain undesirable?

The cassette’s teeth may become harmed when the stretched chain deteriorates. It is useless to replace the chain at this point. Both the old worn-out cassette and the chain will need to be replaced because they will not mesh smoothly.

 Why is the chain on my chainsaw not holding tight?

Make sure the bar is not worn down and look for any debris in the area. The shallow rails will be obvious if it is. If so, a replacement will be necessary. Additionally, you should check to see whether your chain oiler is functioning properly and if the chain itself has any teeth that are damaged.

 What is the lifespan of chainsaw chains?

The average chainsaw chain will last 1 to 5 years. The chain won’t last more than a year if you use your chainsaw frequently and on challenging assignments. The chain, however, may survive longer than five years if you only use it occasionally and practice good maintenance.
