Causes of a Chainsaw Chain Falling Off
There are a few different reasons why your chainsaw chain might keep falling off. Here are some of the most common causes:
Improper tensioning:
If the chain is too loose, it will be more likely to fall off. To check the tension, hold the chainsaw with the chain off the ground and pull on the chain with your hand. The chain should have a slight amount of slack, but it should not be able to move freely. If the chain is too loose, tighten it by turning the tensioning screw clockwise.
Damaged or worn chain:
A damaged or worn chain can also cause it to fall off. If the chain is damaged, it will need to be replaced. If the chain is worn, you can try sharpening it. However, if the chain is too worn, it will eventually need to be replaced.
Incorrect sprocket alignment:
The sprockets on your chainsaw are responsible for driving the chain. If the sprockets are not aligned properly, it can cause the chain to fall off. To check the alignment, turn the chainsaw on and let it run for a few seconds. The chain should move smoothly around the sprockets. If the chain is jumping or skipping, the sprockets are not aligned properly. You can adjust the sprocket alignment by loosening the bolts that hold the sprockets in place and then re-aligning them.
Dirty or clogged bar oiler:
The bar oiler on your chainsaw is responsible for lubricating the chain. If the bar oiler is dirty or clogged, it will not be able to lubricate the chain properly. This can cause the chain to wear down faster and eventually fall off. To clean the bar oiler, remove the oiler cap and clean out the inside of the oiler with a rag. You can also try using a small brush to clean out any debris that may be stuck in the oiler.
Incorrect bar size:
The bar on your chainsaw is designed to work with a specific chain size. If you use a chain that is not the correct size for your bar, it can cause the chain to fall off. To check the bar size, look at the bar label. The bar size will be listed in inches.
