MOUNTING AND REMOVING HUBBED WHEELS
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
Hubbed wheels install directly on the 5/8"-11 threaded spindle.
1. Thread the wheel on the spindle by hand.
2. Depress the spindle lock button and use a wrench to tighten the
hub of the wheel.
3. 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
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
Depressed center Type 27 grinding wheels must be used with
included flanges. See 10 and 11 of this manual for more information.
1. Install the unthreaded backing flange (G)
on spindle (D) with the raised section
(pilot) against the 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"
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" 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 but-
ton, tighten the clamp nut with a wrench.
5. To remove the wheel, depress the spin-
dle 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.
SURFACE GRINDING WITH
GRINDING WHEELS
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work surface, allowing the tool
to operate at high speed. Grinding rate is greatest when the tool
G
operates at high speed.
3. Maintain a 20˚ to 30˚ angle between the
tool and work surface.
4. Continuously move the tool in a forward
D and back motion to avoid creating gouges
in the work surface.
5. Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying it down.
