Chainsaws are powerful tools used for cutting trees, branches, and other wood-related tasks. They are essential equipment for professional loggers, tree surgeons, and even homeowners who want to maintain their yards.
Why Do Chainsaw Leaking Bar Oil When Sitting
However, chainsaws can sometimes develop problems, such as leaking bar oil when sitting. If you’ve noticed this issue with your chainsaw, don’t panic. It’s a common problem that can be easily fixed.
Â
In this article, we’ll explore the reasons why do chainsaws leaking bar oil when sitting and provide some helpful solutions. We’ll also answer some frequently asked questions about this issue. Let’s get started.
 Â
Worn or Damaged Oil Tank Cap
The oil tank cap is responsible for keeping the oil in the tank when the chainsaw is not in use. If the cap is worn or damaged, it may not be able to seal the oil tank properly, causing oil to leak out.
Â
Cracked or Damaged Oil Tank
If the oil tank itself is cracked or damaged, it may leak oil when the chainsaw is sitting.
Â
Clogged Oil Passages
Sometimes, oil passages in the chainsaw can become clogged with sawdust, dirt, or other debris. This can cause oil to leak out of the chainsaw when it’s not in use.
Â
Incorrect Oil Mix Ratio
If you’re not using the correct oil mix ratio for your chainsaw, it can cause excess oil to build up in the bar and chain area. This can result in the chainsaw leaking bar oil when sitting.
Â
Incorrectly Adjusted Oil Pump
If the oil pump on your chainsaw is not correctly adjusted, it may be pumping too much oil onto the bar and chain, causing excess oil to leak out when the chainsaw is not in use.
