Saw chain
It is very important for smooth and safe operation
to keep the cutters always sharp.
Your cutters need to be sharpened when:
• Sawdust becomes powder-like.
• You need extra force to saw in.
• The cut way does not go straight.
• Vibration increases.
• Fuel consumption increases.
Cutter setting standards:
Be sure to wear safety gloves.
Before filing:
• Make sure the saw chain is held securely.
• Make sure the engine is stopped.
• Use a round file of proper size for your chain.
