Use a suitable silicone carbide stick-type dresser or the
wheel dresser provided with the grinder (Fig. 12). Move
the dresser forward on the tool rest until it touches the
high point on the face of the wheel. Dress the wheel by
moving the dresser back and forth. Repeat this operation
until the face of the grinding wheel is clean and the
corners of the wheels are square.
DRESSING THE GRINDING WHEEL
1. Remove the screws (A) Fig. 11 and the side covers
(B) from the grinding wheel.
2. To prevent shaft rotation, place a wedge between the
grinding wheel (C) and the tool rest (D).
NOTE:
To remove the left grinding wheel, turn the arbor
nut clockwise (toward the front) to loosen. To remove the
right grinding wheel, turn the arbor nut counter-
clockwise (toward the front) to loosen.
3. If the replacement wheel does not require the arbor
bushing, save it for future use.
4. To install a new wheel, reverse the procedure.

Do not overtighten the wheel nuts when installing grinding wheels. Tighten the wheel nuts enough to
drive the wheel and prevent slippage.
