Changing The Grinding Wheels - pro.point 8656852 User Manual

8656852
Truing or dressing the wheel is best done using a star-wheel
dresser, a silicon carbide stick type dresser or a diamond faced
dressing tool.
Dress the wheel by moving the dresser forward on the tool rest
until it just touches the highpoint on the face of the wheel, then
dress the wheel by moving the dresser back and forth across
the wheel face.
Repeat this procedure until the face of the grinding wheel is
clean and the corners of the wheels are square.

CHANGING THE GRINDING WHEELS

WARNING! Use only grinding wheels rated for 1,725 RPM or higher
with a 1 in. arbor hole and the appropriate sized bushing. Never
use a grinding wheel rated lower than 1,725 RPM or attempt to
machine an undersized wheel to fit the arbor. The grinding wheel
may fragment during grinding and cause an injury.
1. Prevent the shaft from rotating by placing a wedge
between the wheel and the tool rest.
2. Remove the five screws (#1) attaching the protective side
cover to the grinder. Remove the side cover.
3. Loosen the hex nut. The left nut (#6) has a left-hand
thread. The right nut (#25) has a right-hand thread.
4. Remove the hex nut, the flange (#5) and the old wheel.
5. Install the replacement wheel and outer flange on the shaft.
Make sure the wheel is a tight fit on the shaft.
6. Replace the arbor nut and tighten enough to drive the
wheel and prevent slippage. Excessive tightening can cause
the wheel to crack prior to or during operation.
7. Replace the side cover. Reinsert the five screws and tighten
the side cover in place.
8. Adjust the tool rest and spark shield guard distance from
the grinding wheel. Maintain a separation of 1/8 in. or less
as the wheel diameter decreases from use.
