Cleaning the oil discharge hole
Small dust or particles may be built up in the oil dis-
charge 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.

3. Insert the battery cartridge into the tool. Pull the
switch trigger to flow built-up dust or particles off the oil
discharge hole by discharging chain oil.
4. Remove the battery cartridge from the tool.
Reinstall the sprocket cover and saw chain on the tool.
