5 2 1 Preparing the grinding wheel

WARNING Before a chain is sharpened,
make sure that the grinding wheel is not
cracked, does not vibrate, or wobble. Perform
a "ring test"; see section 4.7, "Installing the
grinding wheel." If the grinding wheel is
damaged, it must be replaced immediately; see
section 6.3, "Change the grinding wheel and fit
the grinding wheel guard."
If abnormal vibrations occur during operation,
immediately stop the machine and check the
condition of the grinding wheel. Make sure all
the switches are turned off before turning the
power back on.
Note: Before each chain is sharpened, make
sure the grinding wheel edges match the shape
of the chain type.
The condition, type and profile of the grinding
wheel is essential for the machine's accurate
operation. The instructions that follow contain
information on how to make sure that the
grinding wheel is in good condition and has the
correct profile.
