How to store a chainsaw so it doesn’t leak oil

Nick Greenway is a chainsaw expert who runs, where he shares his chainsaw knowledge with all. He tells us, “Every chainsaw I've owned has leaked bar oil out of it during storage. So, I always place my chainsaw on a piece of cardboard to soak up any oil that leaks out.”

1. Empty of oil before storing

Consider draining the chainsaw completely before storing it away at the end of the season. If you use your chainsaw seasonally, for instance to cut logs for Winter or tidy a garden but then don’t need to use it over the Winter then drain the remaining fuel and oil from the tank. 

2. Check the oil line

The oil line feeds bar oil from the oil tank to the oil pump. Any ruptures here will cause build-up in the line and possible leaks. Take the bottom cover off the chainsaw and check the line for visible leaking. Replace if necessary. 

3. Don’t overfill your chainsaw’s oil storage tank

During summer, you might be using your chainsaw day to day or week to week and it isn’t practical to empty the tank every time. When storing between uses, make sure your oil storage tank isn’t overfull. As oil expands with temperature changes, a drop or spike in temperatures could see it seeping out of the tank if it’s too full, especially if it’s stored in an uninsulated garage or outhouse. 

To combat this, take note of the capacity in your storage tank and ensure you don’t leave it more than two thirds full.

4. Ensure the oil plug is working

The oil plug will degrade over time. Becoming misshapen or developing small cracks could break the plug’s seal and leave your chainsaw vulnerable to the oil seeping out from the oil tank, especially when stored still over a long period of time. Replacements are usually inexpensive and readily available from the original supplier of your chainsaw. 

5. Protect against leaks

Unfortunately, knowing how to store a chainsaw so it doesn’t leak oil isn’t always enough to prevent it happening. Even the experts have a hard time stopping chainsaw oil from leaking, so do take precautions in how you store it. As Nick Greenaway suggests, place your chainsaw on a piece of cardboard so that it won’t make a mess on your garage floor. This will simplify any clean up.
