Cleaning the guide bar

Chips and sawdust will build up in the guide bar
groove. They may clog the bar groove and impair
the oil flow. Clean out the chips and sawdust
every time when you sharpen or replace the saw
chain.
Cleaning the sprocket cover
Chips and saw dust will accumulate inside of the
sprocket cover. Remove the sprocket cover and
saw chain from the tool then clean the chips and
saw dust.
Cleaning the oil discharge hole
Small dust or particles may be built up in the oil
discharge hole during operation. These dust or
particles may impair the oil to flow and cause an
insufficient lubrication on the whole saw chain.
When a poor chain oil delivery occurs at the
top of guide bar, clean the oil discharge hole as
follows.
1. Remove the sprocket cover and saw chain
