located on the backside of the motor (the
white switch with the dash mark pushed
down) (see Figure 15).
7. Lower the grind head/wheel into the grind
position and grind the chain cutter (see

first. Example - If the first cutter to be
ground is a right hand cutter, then grind all
right hand cutters before changing the
grind setting to the left hand grind position
or vice versa.
10. Once all cutters of the same side (left or
right) have been ground, repeat steps 2 - 9
in section D, on opposite side cutters.

To dress the wheel for depth gauges, place
dressing brick level on top of chain vise, then
