6.3 Changing the grinding wheel and
fitting the grinding wheel guard
WARNING Before a chain is sharpened, make
sure that the grinding wheel is not cracked, does
not vibrate or wobble. There is a simple test (called
the "ring test") that you can do to check for damage
(see step 1 of section 5.2.1, "Preparing the grinding
wheel").
IF THE GRINDING WHEEL IS DAMAGED IT
MUST BE REPLACED IMMEDIATELY. If abnormal
vibrations occur during operation, stop the machine
immediately and check the condition of the grinding
wheel.
The machine comes with 3 grinding wheels of
different sizes. To order more grinding wheels, see
section 8, "Accessories and Spare Parts".
