Installing grinding Wheel
To install the grinding wheel:
1. disConnECt maChinE From poWEr!
2. select the correct grinding wheel for your
chain (refer to grinding Wheel Selection on
Page 20 for detailed information).
3. perform the Wheel Inspection & Ring Test
procedure as instructed on Page 21. if the
wheel does not pass visual inspection or the
ring test—do not use it!
4. if necessary, dress the wheel (refer to
Dressing grinding Wheel on Page 29 for
detailed information).
5. if installed, remove the arbor and wheel
safety guards, as shown in figure 12, by
unthreading the two hex bolts that secure
them.
6. remove the arbor cap screw and outer
flange, then place the grinding wheel on the
inner flange.
7. replace the outer flange and arbor cap
screw, then tighten the cap screw to approxi-
mately 60 inch pounds.
Over-tightening the arbor cap screw could
cause the grinding wheel to crack and break
apart during operation, which would send
flying debris at the op erator. DO NOT over-
tighten the arbor cap screw. If possible, use
a torque wrench to ensure that the cap screw
is not tightened more than 6 0 inch pounds.
8. replace the wheel and arbor safety guards
(see figure 13).
figure 13. grinding wheel and safety guards

During operatio n, sparks and debris are
thrown from the wheel and chain. To reduce
the risk of operator injury from this mate-
rial, ALWAyS make sure the wheel and arbor
safety guards are correctly installed before
connecting the sharpener to power!
