Why Does My Husqvarna Chainsaw Leak Bar Oil
The most likely reason your Husqvarna chainsaw is leaking bar oil is that the oil reservoir cap is not fully tightened, or the O-ring on the cap is damaged. If the problem persists after checking and correcting these issues, then it is possible that the oil pump diaphragm has ruptured.
If your Husqvarna chainsaw is leaking bar oil, there are a few possible causes. First, check to see if the oil reservoir is overfilled. If so, simply drain some of the oil out until it reaches the fill line.
Another possibility is that the O-ring on the bar oiler tube is damaged or missing. Replacing the O-ring should fix the problem. Finally, it’s possible that the bar oil pump itself is defective.
If this is the case, you’ll need to replace the pump.

Why Does My Chainsaw Leak Bar Oil When Not in Use?
It’s normal for chainsaw bar oil to leak a little when the saw is stored. The oil keeps the bar and chain lubricated and cooled, so it needs to be in contact with them. Some of the oil will seep past the seals and gaskets in the saw, especially if it’s left lying on its side.
The good news is that this leaking won’t damage your saw or affect its performance. You can reduce the amount of leakage by wiping down the bar and chain before storing the saw, and by making sure that the tank is filled to the correct level (just below the max line). If you notice that your chainsaw is leaking a lot of oil, or if it starts to smoke or make strange noises, then take it to a qualified technician for servicing.
Where Does the Bar Oil Come Out on a Husqvarna Chainsaw?
The bar oil on a Husqvarna chainsaw comes out of the top of the saw near the front. It is released through a small hole in the side of the bar when the trigger is squeezed. The amount of oil that comes out can be adjusted by turning a knob on the side of the saw.
Why Would Oil Come Out of Exhaust on Chainsaw?
If you notice oil coming out of your chainsaw’s exhaust, it’s most likely due to a problem with the saw’s piston or cylinder. When these parts are damaged or worn, they can allow oil to leak into the combustion chamber and be burned along with the fuel. This will cause a blue-ish smoke to come out of the exhaust as well as decreased performance from the saw.
If you’re seeing this issue, it’s best to take your chainsaw to a qualified repair shop for diagnosis and repairs.
Can You Put Too Much Bar Oil in a Chainsaw?
It is important to use the correct amount of bar and chain oil when operating a chainsaw. Too much oil can cause the saw to produce more smoke, run less efficiently, and create more sludge inside the engine. Excess oil can also build up on the guide bar and chain, making them more likely to slip.
