How to Adjust a Bar Oiler on a Husqvarna Chainsaw

Updated February 21, 2017

The bar oiler on a Husqvarna chainsaw lets you manually adjust the output volume of bar oil. While the bar oil flows automatically via a pump, you can increase or decrease the desired amount of lubrication. Each cutting job may require a different oil setting and, as the Husqvarna ages, you may need to increase the oil output to keep the chain properly lubricated. While over-lubricating may only waste oil, under-lubricating can cause serious damage to the clutch and crankshaft.

Turn off the engine on your Husqvarna. Lay the chainsaw onto a flat work area. Turn the Husqvarna upside down.

Locate the bar oiler adjustment screw on the bottom of the engine; this screw will be marked with an oiler and a drop of oil. Turn the screw with the screwdriver towards the "plus" symbol, or counterclockwise, to increase the oil; turn the screw to the "minus" symbol, or clockwise, to decrease the oil.

Turn the chainsaw on. Throttle the trigger. Hold the tip of the bar 1 inch away from a piece of wood; when oil is properly set, a light splattering of oil will hit the piece of wood. Continue monitoring oil output volume while cutting and make any adjustments as necessary.


You should perform the oil check after each refuelling.
