MAINTENANCE

Guide Bar

1. Clean before using.
2. Clean the groove of the guide
bar (A) with a small
screwdriver.
3. Clean oil holes (B) with a wire.
4. Invert guide bar periodically.
5. Clean the guide bar mount area
before installing the guide bar.

Sprocket

• A damaged sprocket will cause
premature damage or wear of
saw chain.
• When the sprocket has worn 0.5
mm (0.020 in.) or more, replace it.
• Check sprocket when you install
new chain. Replace it if worn.
Some tree sap and resins are corrosive. Thoroughly wash the guide
bar and sprocket areas after each use, then coat metal parts with light
oil.

Cooling System Cleaning

• Check periodically.
• Clogged fins will result in poor
engine cooling.
1. Remove the recoil starter and
the air guide plate.
2. Use compressed air or wooden
tool to remove dirt and dust
from between fins to let cooling
air pass easily.
