1. Check the contact between the stone and
chain before advancing the Power Sharp _
Knob. If stone is contacting the chain, the
chain can be sharpened without advancing
the knob.
2. Do not advance the Power Sharp® Knob
more than one or two clicks at any one
sharpening.
Otherwise, excessive wear to
the chain and sharpening stone can occur.
3. Note
the
flow
of
sparks visible during
automatic sharpening:
_A
light flow
of sparks
indicates
proper
sharpening.
--A
heavy flow Of sparks
or no sparks in-
dicates improper sharpening.
4. Keep all cutters the same length. The side
plates shou}d always bekept
approximately
1132 of an inch longer than the top plate.
Figure 21.
5. Preserve the original cutter angles carefully
and uniformly.
6. Avoid hand filing into the bottom of the top
plates. Keep guide lines on file guide aligned
with the chain and guide bar.
