MOUNTING A GRINDING WHEEL
To replace the grinding wheel: See FIG. 5.
!
VERIFY THAT THE WHEEL TO BE INSTALLED IS
IN GOOD CONDITION. SEE PAGES 4 AND 5 FOR
SAFETY INFORMATION ON GRINDING WHEELS.
1. First, turn the power off by pushing in the Emergency
Stop button.
2. Use the grinding wheel wrench supplied with the
grinder to unscrew the mounting flange that holds the
grinding wheel,.
!
THE LOCK FLANGE HAS A LEFT HANDED
THREAD, HOLD THE WHEEL AND TURN THE
WRENCH CLOCKWISE WHILE LOOKING AT
THE LOCK FLANGE TO LOOSEN.
3. Remove the old wheel and install the new one.
4. Screw on the flange finger tight, then tighten
approximately 1/8 turn further with the wrench.
The flange will self-tighten when motor is turned on.
IF THE WHEEL FLANGE IS OVERTIGHTENED, THE
GRINDING WHEEL MAY CRACK AND FLY APART.
5. After you install a new or different wheel, it is recommended that you dress it before grinding. (See
next page) Dressing the wheel trues the grinding surface of the wheel and removes the hard glaze
sometime remaining from the manufacturing process. Dressing the wheel properly prepares the wheel
for grinding.
REPLACING THE WHEEL
A new vitrified grinding wheel is 2" [51 mm] deep. Replace the
wheel when it wears down to a depth of 0.75" [19 mm].
