■ SAW CHAIN
It is very important for smooth and safe operation
to keep the cutters always sharp.
The 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.
File size: 5/32 in (4.0 mm)
Place your file on the cutter and push straight forward.
Keep the file position as illustrated. (F11-3)
After every cutter has been set, check the depth gauge
and file it to the proper level as illustrated. (F11-4)
Be sure to round off the front edge to reduce the
chance of kickback or tie-strap breakage.
