SIDE PLATE ANGLE
See Figure 48.
 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.
MAINTAINING DEPTH GAUGE
CLEARANCE
See Figure 49 - 51.
 Maintain the depth gauge at a clearance of .025
in. 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 .025 in. depth gauge
tool. After lowering each depth gauge, restore
original shape by rounding the front. Be care-
ful not to damage adjoining drive links with the
edge of the file.
 Depth gauges must be adjusted with the flat file
in the same direction the adjoining cutter was
filed with the round file. Use care not to contact
cutter face with flat file when adjusting depth
gauges.
