SPINDLE LOCK (FIG. 7)
The spindle lock (C) is provided to prevent the
spindle from rotating when installing or removing
wheels. Operate the spindle lock only when the
tool is turned off, unplugged from the power
supply, and has come to a complete stop. Do
not engage the spindle lock while the tool is
operating because damage to the tool will
result. To engage the lock, depress the spindle
lock button and rotate the spindle until you are
unable to rotate the spindle further.
Mounting and Using Depressed Center
Grinding Wheels and Sanding Flap Discs
MOUNTING AND REMOVING HUBBED WHEELS
Hubbed wheels install directly on the 5/8"-11 threaded spindle.
Thread of accessory must match thread of spindle.
1. Backing flange is retained to the grinder by an O-ring on the
spindle. Remove backing flange by pulling and twisting flange
away form the machine.
2. Thread the wheel on the spindle by hand.
3. Depress the spindle lock button and use a wrench to tighten the
hub of the wheel.
4. Reverse the above procedure to remove the wheel.
CAUTION: Failure to properly seat the wheel before turning the
tool on may result in damage to the tool or the wheel.
MOUNTING NON-HUBBED WHEELS (FIG. 8, 9)
Depressed center Type 27 grinding wheels must be used with
included flanges.
NOTE: The 3" (76 mm) diameter stamped steel backing flange (G2)
is ONLY for use with 6" (152 mm) Type 27 grinding wheels. Refer to
FIG. 7
pages 9–11 for more information.
1. Install the 3" (76 mm) diameter stamped
steel backing flange (G2) for 6" (152 mm)
C
Type 27 wheels or the 1-11/16" (43 mm)
diameter quick-change backing flange
(G1) for all other non-hubbed wheels on
spindle (O) with the raised section (pilot)
against the wheel. Be sure the backing
flange recess is seated onto the flats of the
spindle by pushing and twisting the flange
before placing wheel.
2. Place wheel against the backing flange,
centering the wheel on the raised section
(pilot) of the backing flange.
3. While depressing the spindle lock button,
thread the clamp nut (H) on spindle. If
the wheel you are installing is more than
1/8" (3.17 mm) thick, place the threaded
clamp nut on the spindle so that the raised
section (pilot) fits into the center of the
wheel. If the wheel you are installing is 1/8"
(3.17 mm) thick or less, place the threaded clamp nut on the
spindle so that the raised section (pilot) is not against the wheel.
4. While depressing the spindle lock button, tighten the clamp nut
with a wrench.
5. To remove the wheel, depress the spindle lock button and loosen
the threaded clamp nut with a wrench.
NOTE: If the wheel spins after the clamp nut is tightened, check the
orientation of the threaded clamp nut. If a thin wheel is installed with
the pilot on the clamp nut against the wheel, it will spin because the
height of the pilot prevents the clamp nut from holding the wheel.
