Figure 20. Typical chainsaw 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 perform
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
