TOP PLATE FILING ANGLE
(See Figure 42)
•
CORRECT 30°
–
file holders are marked with guide marks to align file properly to produce correct top plate angle.
•
LESS THAN 30°
–
for cross cutting.
•
MORE THAN 30°
–
feathered edge dulls quickly.

•
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
(See Figure 44-46)
•
Maintain the depth gauge at a clearance of 1/32" (0.6 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 1/3
’’
(0.6mm) depth gauge jointer.
After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining
drive links with the edge of the file.
