MAINTENANCE
Properly tension the chain prior to sharpening.
Refer to Chain Tension section earlier in this
manual. Do all of your filing at the mid-point of
the bar.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth.
Do not let the file dip or rock.
Using light but firm pressure, stroke towards
the front corner of the tooth.
Lift file away from the steel on each return
stroke.
Put a few firm strokes on every tooth. File all left
hand cutters in one direction. Then move to the
other side and file the right hand cutters in the
opposite direction. Occasionally remove filings
from the file with a wire brush.
WARNING
Improper chain sharpening increases the po-
tential of kickback, which can result in serious
personal injury.
WARNING
Failure to replace or repair damaged chain can
cause serious injury.
Top Plate Filing Angle
See Figure 40.
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 41.
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.
