Husqvarna Chainsaw Leaking Bar Oil? [5 Reasons & Solutions]

Owning a Husqvarna chainsaw can be really handy. But it becomes really troublesome if you notice oil leaking from it. We know how worrying it is.

So, what are the reasons for the Husqvarna chainsaw leaking bar oil?

The leakage you see might not be leakage at all. It might be just the residue of oil sprayed on the chain. But if it’s actually the oil leaking, it can be due to an oil system blockage. In that case, try to clean it. If improper viscosity of the oil is the reason, try choosing a good oil. If it’s because of faulty oiler settings, try changing the settings.

That was only the overview of our piece on this topic. If you want to know more read this article.

5 Reasons Why Husqvarna Chainsaw Might Leak Bar Oil

Small droplets stay inside the grooves while operating the chainsaw. Gradually they run down to the surface of the chainsaw. This makes us believe that our chainsaw is leaking. The most usual reason for bar oil leakage is this.

Along with this issue, there are a few specific issues too. But it is really uncommon that this happens due to machine malfunction.

We are listing all the reasons and their solutions below-

Reason 1: Overfilled Oil Level

Oil is a temperature-sensitive liquid. This means it might increase in volume with the rise in temperature.

Overfilling oil is a major reason for oil spills due to temperature variation. Moreover, you must keep the saw on an even surface. Otherwise, the packed oil inside will spill.

Solution

You can use a degreasing agent mixed with warm water to clean leaked oil. 

To prevent this, chainsaws must not be kept with its tank full of oil. Even if you do, try to keep the chainsaw under constant temperature. But we would rather suggest filling the oil tank only prior to use. 

Also, keep the chainsaw on an even surface. 

Reason 2: Deposited Oil in Grooves

The chain goes around the sprocket beneath the clutch clover while revolving. In the meantime, oil is splurged from the revolving chain onto the saw’s body.

The oil might get retained by grooves and recesses. And once you store the chainsaw this oil might run downwards. As a result, you might notice the pool of oil right under your chainsaw.

Solution

This solution is really easy and quite effective. To do this, first, you need to remove the bar and chain. Then soak it with a mix of a degreasing agent with warm water. Finally, take a dry cloth or some dry cotton pads to wipe all the oil residue.

The most amount of residue accumulates on grooves and recesses. Try to clean those places thoroughly till you completely remove all residue oil.

Reason 3: Oil System Blockage

Husqvarna chainsaw has a bar tip sprocket. It generally turns and allows the oil to reach the chain. 

However, sometimes it tends to get stuck or restricted. This causes the hole in the tip to get blocked. As a result, the oil finds it difficult to reach the chain.

Clogged channels around the guide bar can also block the oil flow. This results in the oil running down to the bottom of the chainsaw.

Solution

Cleaning the oil system blockage is very simple.

Check the sprocket, if it’s stuck lubricate till it becomes free. Make sure you don’t feel any resistance while turning it.

Cleaning the sprocket tip is the second step here. This contributes to better oil flow to the chain. You need to check the channel running around the edge of the guide bar too. Ensure that the channel is not clogged. Because if it is, it will block the oil.

Reason 4: Automatic Oiler Settings

Some of the Husqvarna chainsaw models consist of an adjustable screw. It helps to set the level of oil output manually. 

But improper adjustment might be the reason your Husqvarna chainsaw leaking bar oil. Setting it at the lowest point will create problems for the automatic oiler. It will not be able to release enough oil.

On the other hand, if you set the oiler too high, excess oil might be released. This extra amount of oil can’t be contained on the chain. Thus, this extra oil runs out of the bottom.

Solution

It is better to prevent this problem from happening. As it’s tough to clean that excess amount of oil with a degreasing agent.

To prevent this try to keep the setting at an optimum point. Do not let the setting be too low or too high.

Reason 5: Improper Oil Viscosity

Viscosity means a fluid’s resistance to flow. Here, the oil reducing the wear of the chain has a specific viscosity. The oil to be used must not be too thin or too thick.

If not so, the oil will not adhere to the surface of the chain. It will gradually run down from the surface of the chain. Resulting in the leaking of oil from the saw.

Solution

Try cleaning the leaked oil with a degreasing agent soaked cotton pad.

Picking a suitable oil is the only possible solution here. It should have optimum viscosity. It must also adhere to the chain. This way it won’t leak from the bottom of the chainsaw.
