■ 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 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: 25AP
File size: 5/32 in (4.0 mm)
Place the file on the cutter and push straight forward.
Keep the file position as illustrated.
After each cutter has been filed, check the depth gauge
and file it to the proper level as illustrated.

Depth gauge standard
.025 (0.64 mm)
Be sure to round off the front edge to reduce the
chance of kickback or tie-strap breakage.
Make sure every cutter has the same length and edge
angles as illustrated.
■ GUIDE BAR
• Reverse the bar occasionally to prevent partial wear.
• The bar rail should always be square. Check for wear
of the bar rail. Apply a ruler to the bar and the out-
side of a cutter. If a gap is observed between them,
the rail is normal. Otherwise, the bar rail is worn.
Such a bar needs to be corrected or replaced.
