How to Keep Chainsaw from Leaking Bar Oil

To keep a chainsaw from leaking bar oil, the most important thing to do is ensure that the chain brake and chain tensioner is in good condition. Check for any worn-out or missing parts, as these can cause leaks. Additionally, make sure that all screws and bolts are tightened properly.

You should also check the oil level regularly and fill it up when needed. If there is an old or damaged gasket or seal around the bar window, replace it with a new one. Finally, use a high-quality lubricant specifically designed for chainsaws to ensure optimal performance of your saw and prevent leakage of bar oil over time.

  • Step 1: Check the bar oil cap for any signs of damage. Make sure it is properly attached and not loose or cracked. If there is a problem, replace the cap with an undamaged one.
  • Step 2: Inspect all other parts of your chainsaw to make sure that they are in good condition. Look for any pieces that may be worn down, cracked, or damaged in some way that could cause a leak.
  • Step 3: Tighten all screws on the chainsaw to ensure that everything is securely held together so there won’t be any gaps where oil can escape from.
  • Step 4: Clean out the sawdust and debris from around the chain and bar to help keep them lubricated and prevent too much leakage when you use it again.
  • Step 5: Replace old or dirty bar oil if needed; this will help reduce friction and heat buildup between your chain and bar, which can lead to leaking problems over time.

Why is My Chainsaw Leaking Bar Oil?

If your chainsaw is leaking bar oil, it could be due to a few different issues. The most common cause of this problem is that the oiler tube or reservoir has become cracked or blocked. This can allow bar oil to leak out when the chainsaw is in use and not properly lubricating the chain.

It’s also possible that there might be a loose connection between the oil tank and hose allowing for an air leak which in turn causes bar oil to escape from its containment. Lastly, an improperly adjusted tension on the saw chain can lead to too much pressure being applied which will force some of the excess bar oil out as well.

To fix these problems you should check all connections and make sure they are secure, clean any buildup that may have formed in the tube or reservoir, ensure proper tension on your saw chain, and consider replacing any damaged parts if necessary.

Is It Normal for Oil to Leak from Chainsaw?

Yes, it is normal for oil to leak from chainsaws. This usually occurs when the bar or chain oil tank has become overfilled, which can happen if too much oil was added during maintenance or refilling. Leaking oil can also occur if the O-ring on the cap of the reservoir becomes worn out and needs replacing, as this will cause an excessive build-up of pressure in the tank and result in a leak.

In order to prevent this from happening it’s important to ensure that you are not overfilling your chainsaw with bar/chain lubricant and regularly checking your O-rings for wear.

Why is My Stihl Chainsaw Leaking Oil from the Bottom?

A Stihl chainsaw that is leaking oil from the bottom could have a few different issues causing this. The first, and most common cause, is that the chain bar needs to be lubricated or replaced. A worn-out or damaged chain will not create enough suction to force the oil up into the bar properly, resulting in it dripping down from underneath.

Another potential issue could be a loose fitting on one of the hoses leading to or from the tank, allowing excess oil to escape and pool at the bottom of your saw. Lastly, if you recently filled up your chainsaw with fresh fuel and/or oil then it’s possible that overfilling has caused some of it to run out through an unsealed part in order for proper levels to balance out again inside your engine.

How Do You Store a Dewalt Chainsaw So It Doesn’t Leak Oil?

When storing a Dewalt chainsaw, it is important to take measures to prevent oil from leaking out. Firstly, ensure that the chainsaw is completely drained of any fuel or oil before storage. To do this, turn off the switch and use a funnel and paper towels to drain out all remaining fluid from the tank and carburetor.

Secondly, check for any loose screws or bolts and tighten them if necessary. Finally, store your chainsaw in an upright position on a flat surface with its chain guard facing up so that no oil can leak through while it’s in storage.

Chainsaw Leaks Bar Oil When Stored

One common issue with chainsaws is that they can leak bar oil when stored for a long period of time. This occurs because the seals around the piston, cylinder, and crankcase deteriorate over time due to heat, vibration, and age. As these seals break down, bar oil can escape from the engine and drip out from underneath your chainsaw.

To prevent this from happening, it’s important to regularly inspect your chainsaw for signs of wear or damage, as well as keep it properly lubricated by changing its bar oil on a regular basis.


By following the steps outlined in this blog post, you should be able to keep your chainsaw from leaking bar oil. Not only will this help maintain a clean workspace, but it will also ensure that your chainsaw is running at optimum performance and won’t cause any damage to yourself or others nearby.

If necessary, take extra measures such as replacing old components or cleaning out debris buildup to keep your chain saw free of bar oil leaks. With proper maintenance and care, you can enjoy safe and efficient use of your chain saw for years to come!
