Ryobi CCW180LBC - Cutter Filing Angles; Depth Gauge Clearance

23
Putafewrmstrokesoneverytooth.Fileallleft
hand cutters in one direction. Then move to the
othersideandletherighthandcuttersinthe
oppositedirection.Occasionallyremovelings
fromthelewithawirebrush.
WARNING:
Improper chain sharpening increases the
potential of kickback.
WARNING:
Failure to replace or repair damaged chain can
cause serious injury.
WARNING:
The saw chain is very sharp, always wear
protective gloves when performing maintenance
to the chain.
TOP PLATE FILING ANGLE
See Figure 34.
 CORRECT 30° - File 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
See Figure 35.
 CORRECT - 80° Produced automatically if
correctdiameterleisusedinleholder.
 HOOK - “Grabs” and dulls quickly. Increases
potential of KICKBACK.
 Resultsfromusingalewithdiametertoosmall,
orleheldtoolow.
 BACKWARD SLOPE - Needs too much feed
pressure, causes excessive wear to bar and
chain.
 Resultsfromusingalewithdiametertoolarge,
orleheldtoohigh.

DEPTH GAUGE CLEARANCE
See Figure 36 - 38.
 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led, checkthe depth
gauge clearance.
Useaatle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.
