BAR & CHAIN MAINTENANCE
Be sure to wear safety gloves. See NOTE 1.
It is very important for smooth and safe operation to keep the chain sharp at
all times.
Your cutters need to be sharpened when:
•
Sawdust becomes powder-like.
•
You need extra force to saw.
•
The cut does not go straight.
•
Vibration increases.
•
Fuel consumption increases.
