CARE AND MAINTENANCE
Top plate ling angle
• CORRECT 30° – le holders are marked with guide
marks to align le properly to produce correct top
plate angle.
• LESS THAN 30° – for cross cutting.
• MORE THAN 30° – feathered edge dulls quickly.
Side plate angle
• Correct 80° – Produced automatically if you use the
correct diameter le in the le holder.
• Hook – “Grabs” and dulls quickly; increases the
potential of kickback. Results from using a le with a
diameter too small or a le held too low.
• Backward Slope – Needs too much feed pressure;
causes excessive wear to the bar and chain. Results
from using a le with a diameter too large or le held
too high.
Side plate angle
• Maintain the depth gauge at a clearance of 1/32 in.
(0.6 mm). Use a depth gauge tool for checking the
depth gauge clearances.
• Every time the chain is led, check the depth gauge
clearance.
