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 build up in the oil discharge hole during operation. The dust particles may
impair the oil to flow and cause 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.
