figure 22. typical chain saw sharpening specifications.
grinding wheels that break apart during
operation can send high-speed debris at
the operator or bystanders. ALWAyS visu-
ally inspect the grinding wheel and per form
the ring test ( see Wheel Inspection & Ring
Test on the next page for detailed instruc -
tions) before mounting the wheel onto the
sharpener. If there is visual damage or the
wheel does not pass the ring test—DO NOT
use it!
use the chart in figure 22 as a general guide
when selecting the proper grinding wheel for your
chain saw. however, we recommend that you
always refer to the chain manufacturer's specifica-
tions when setting up the sharpener.
