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
from the tool.
2. Remove the small dust or particles using a
slotted screwdriver or the like.
