11. MAINTENANCE OF SAW CHAIN AND GUIDE BAR

Saw Chain

It is very important for smooth and safe operation to always 

keep the cutters sharp.

The cutters need to be sharpened when:

•  Sawdust becomes powder-like.
•  You need to apply extra force to the chainsaw.
•  The cut path 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 has stopped.
•  Use a round file of proper size for the chain.
