Cutter setting guidance
WARNING!
Be sure to wear safety gloves.
Before filing:
1. Make sure the saw chain is held securely.
2. Make sure the engine is stopped.
3. Use a round file with the proper size for your chain.
NOTE:
Chain type: 91PJ File size: 5/32 in (4mm). Place your file
on the cutter and push straight forward. Position the file as
illustrated.
After each cutter has been set, check the depth gauge and file it
to the proper level as illustrated. Make sure each cutter has the
same length and angle as illustrated.
Chain Bar
1. Reverse the bar occasionally to prevent partial wear.
2. The bar rail should always have parallel internal faces (see
diagram). 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.
