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
WARNING: To reduce the risk of serious personal injury, turn
tool off and and remove battery pack before making any
adjustments or removing/installing attachments or accessories.
Depressed center Type 27 grinding wheels must be used with
included flanges. See pages 11 and 12 of this manual for more
information.
1. Install the anti-lockup backing flange (F)
on spindle (P) 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 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 (G) 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.

SURFACE GRINDING WITH
GRINDING WHEELS
1. Allow the tool to reach full speed before
touching the tool to the work surface.
P
2. Apply minimum pressure to the work surface, allowing the tool
to operate at high speed. Grinding rate is greatest when the tool
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
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.
EDGE GRINDING WITH
GRINDING WHEELS
WARNING: Wheels used for cutting and edge grinding may break
or kick back if they bend or twist while the tool is being used to do
cut-off work or deep grinding. To reduce the risk of serious injury,
