How to Increase the Oil Pump Flow of a Chainsaw?

[DeAiden]

The oil pump flow of a chainsaw can be increased by inserting a screwdriver into the bottom hole on the clutch side and loosening the inner adjustment. Below are details about the oil pump adjustment: 1. Adjustment Method: Tightening reduces the flow while loosening increases it. Specifically, locate the semi-circular hole at the bottom of the chainsaw—the screw inside can be adjusted. Turning clockwise tightens (reduces flow), and turning counterclockwise loosens (increases flow). 2. Adjustment Steps: First, turn off the engine. Look behind the drive shaft of the chainsaw, slightly loosen the fixed screw of the transmission bearing. There is an adjustment valve between the chain and the bearing, which can be adjusted with a screwdriver. Rotate it slightly by half or a full turn, then manually turn the chain to check the tension. Once properly adjusted, secure the fixed screw and finally reattach the cover.
