MAINTENANCE
WARNING
The saw chain is very sharp, always wear pro-
tective gloves when performing maintenance
to the chain.
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.
Side Plate Angle
See Figure 43.
CORRECT - 80° Produced automatically if cor-
rect diameter file is used in file holder.
HOOK - "Grabs" and dulls quickly. Increases
potential of KICKBACK.
Results from using a file with diameter too small,
or file held too low.
BACKWARD SLOPE - Needs too much feed
pressure, causes excessive wear to bar and
chain.
Results from using a file with diameter too large,
or file held too high.
Depth Gauge Clearance
See Figures 44 - 45.
The depth gauge should be maintained 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. Depth gauge jointers are
available in .020 in. to .035 in. Use a .025 in. 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.
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.

Guide Bar Maintenance
When the guide bar shows signs of wear, reverse
it on the saw to distribute the wear for maximum
bar life. The bar should be cleaned every day of
use and checked for wear and damage.
