MAINTENANCE
TOP PLATE FILING 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.
