■Saw Chain

It is very important for smooth and safe op- eration to always keep the cutters sharp.

The cutters need to be sharpened when:

•Sawdust becomes powder-like.

•You need extra force to saw in.

•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 is stopped.

•Use a round file of proper size for the chain.

Chain type: 91VG

File size:

5/32 in (4.0 mm)
