■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.
Chain type: 21BP
File size: 3/16 in
(
4.76mm
)
Place your file on the cutter and push
straight forward. Keep the file position as
illustrated. (F34)
After every cutter has been set, check the
depth gauge and file it to the proper level as
illustrated. (F35)
Be sure to round off the front edge to
reduce the chance of kickback or tie-strap
breakage.

■GUIDE BAR
·
Reverse the bar occasionally to prevent
partial wear.
·
The bar rail should always be a square.
Check for wear of the bar rail. Apply a ruler
to the bar and the outside 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. (F37)
