CARE AND MAINTENANCE
Side plate angle
• Correct 80° – Produced automatically if you use the
correct diameter file in the file holder.
• Hook – “Grabs” and dulls quickly; increases the
potential of kickback. Results from using a file with a
diameter too small or a file held too low.
• Backward Slope – Needs too much feed pressure;
causes excessive wear to the bar and chain. Results
from using a file with a diameter too large or file held
too high.
Side plate angle
• Maintain the depth gauge at a clearance of 1/32 in.
(0,79 mm). Use a depth gauge tool for checking the
depth gauge clearances.
• Every time the chain is filed, check the depth gauge
clearance.

• Use a flat file and a depth gauge jointer to lower all
gauges uniformly. Use a 1/32 in. (0,79 mm) depth
gauge jointer.
