Why does my Chainsaw Leak Bar Oil when not in use

If you are a homeowner who owns a chainsaw, then this article is for you. Chainsaws are great for cutting up firewood or for general use around your house like trimming back overgrown tree branches.

Chainsaws can sometimes leak bar oil when not in use. This can be from oil stored inside the chainsaw to ensure that it does not evaporate. If your chainsaw leaks while idle, there may be an issue with the fuel pump seal which will need to be replaced.

The problem with leaving a chainsaw unused for long periods is that oil will leak from the bar and onto anything below it – this means that if you leave your chainsaw out in the open, chances are there’ll be an oily patch on the floor every time you go back to use it again.

If you’ve got a chainsaw that leaks oil, then it’s worth changing the seal on the fuel pump. Take care to make sure any residual gas is drained before opening up your chainsaw and replacing anything. Make sure you know what parts go where beforehand – this may mean doing some research online or asking an expert for help if necessary.

What to do If Your Chainsaw Still Leaks Oil

If the chainsaw you’ve got is still leaking oil while idle, even after changing the seal on the fuel pump, then there may be an issue with another part of your chainsaw.

If this is the case, it’s best to bring it into a servicing shop or hire an expert who can fix it for you.

After you’ve started your chainsaw, the oil will be used up by the chain and there won’t be any more leaks afterward – this is why it’s important to start up your saw every now and again even if they’re not in use for long periods.

If you do choose to leave them idle though, make sure you put an old rag or towel underneath to soak up any oil that does leak.

There are several issues that could be causing your chainsaw to leak, but the easiest way to fix it would depend on what kind of leaks you are having.

So if you are tired of chainsaw leaks, then let’s walk through the process of how to fix a leaking bar oil tank. Chainsaws can be expensive and annoying to maintain, but you’ll be able to save time and money in no time.

Step 1: Check your fuel level so that it doesn’t overflow when adding new fuel.

Step 2: To start fixing the leaky bar oil tank, first loosen the cap on top of the engine block near where it connects with the bar oil tank.

Step 3: If there is still an issue after loosening the cap on top of your engine block then go ahead and remove it entirely by unscrewing one or two screws depending on the model of your chainsaw.

The next thing you need to do is make sure that there isn’t any debris blocking up where oil flows into the tank. If you do notice any debris then it is important that you remove it completely and put everything back together again but in reverse order.

If this doesn’t work, then you might need to check your bar oil tank for any cracks where leaks might be coming from.

How to store a chainsaw without oil leaking

If you are tired of chainsaw oil leaking on the floor when not in use, then follow these simple steps to store your chainsaw without having any issues.

Steps:

  1. First off, let’s start by ensuring that there is no more fuel left in the tank which could cause an overflow if it is full when you do store it.
  2. Before storing your chainsaw, make sure that the saw is clean and dry especially if you are planning on putting them in a garage or shed to avoid moisture from developing which could cause rusting.
  3. If possible, try not to put any additional fuel into the tank to prevent any leaks.
  4. If you are planning on storing your chainsaw for a long time then it is best that you drain all the fuel out of the tank completely. Once finished, make sure to put everything back together again.
  5. Once you are done with this step, it is now time to lubricate your chainsaw. You should do this before storing your chainsaw away for a long period of time. Lubricating your chainsaw is vital because if your chainsaw gets completely dry while not in use then there will be no protection against rust and moisture developing which could cause damage inside the engine.

Steps to lubricate your chainsaw before storage:

  • First off, take the spark plug out of your chainsaw and check that it’s dry. If you notice moisture or rust then replace it with a new one for better protection.
  • Next step is to put some bar oil onto the bar and drive the sprocket on the lower side of your chainsaw. Ensure that you don’t add too much oil because it could cause a mess while storing away your chainsaw.
  • Once this is done, put your plug back in and start up the saw for 15 seconds to allow the lubricant to be properly distributed throughout the engine.
  • Letting your chainsaw idle for about 30 seconds will help to drain out excess oil in case there is any left over. Once this is done, shut down the saw and replace the plug again before storing it away safely.
