more than 1/8 inch (3mm) thick, place
the threaded clamp nut on the spindle so
that the raised section (pilot) fits into the
center of the wheel.

4. While depressing the spindle lock button
(6), tighten the threaded clamp nut with
included wrench.
5. To remove the wheel, depress the
spindle lock button and loosen the
threaded clamp nut with included wrench.
NOTE: If the wheel spins after the threaded
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 operates at high speed.
3. Figure J - 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
Wheels used for edge grinding may break
or kick back if they bend or twist while the
tool is being used to do deep grinding. To
reduce the risk of serious injury, limit the
use of these wheels with a standard Type
27 guard to notching (less than 1/2 inch
(13mm) in depth). The open side of the
guard must be positioned away from the
operator. See page 9 for more information.
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 operates at high speed.
3. Position yourself so that the open-
underside of the wheel is facing away
from you.

4. Remove the tool from the work surface
before turning the tool off. Allow the tool
to stop rotating before laying it down.
Do not use edge grinding wheels for surface
grinding applications because these wheels
are not designed for side pressures
encountered with surface grinding. Wheel
breakage and injury may result.
SURFACE FINISHING WITH SANDING
FLAP DISCS
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to work
surface, allowing the tool to operate at
high speed. Sanding rate is greatest
when the tool operates at high speed.
3. Figure K - Maintain a 5˚ to 10˚ 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.
SANDING
MOUNTING SANDING BACKING PADS
WARNING: To prevent accidental
operation, turn off and unplug tool
before performing the following
operations. Failure to do this could result
in serious personal injury.
NOTE: Guard may be removed when using
sanding backing pads. Proper guard must be
reinstalled for grinding wheel, sanding flap
disc, wheel, wire brush or wire wheel
applications after sanding applications are
complete.
1. Figure L - Place or appropriately thread
backing pad (14) on the spindle.

2. Place the sanding disc (15) on the
backing pad (14).
3. While depressing spindle lock, thread
clamp nut (13) on spindle, piloting the
raised hub on the clamp nut into the
center of san ding disc and backing pad.
4. Tighten the clamp nut by hand, then
depress the spindle lock button while
turning the sanding disc until the
sanding disc and clamp nut are snug.
5. To remove the wheel, grasp and turn the
backing pad and sanding pad while
depressing the spindle lock button.
USING SANDING BACKING PADS
Choose the proper grit sanding discs for
your application. Sanding discs are available
in various grits. Coarse grits yield faster
material removal rates and a rougher finish.
Finer grits yield slower material removal and
a smoother finish.
Begin with coarse grit discs for fast, rough
material removal. Move to a medium grit
paper and finish with a fine grit disc for
optimal finish.
Coarse
16 - 30 grit
Medium
36 - 80 grit
Fine Finishing
100 - 120 grit
Very Fine Finishing 150 - 180 grit
1. Allow the tool to reach full speed before
touching tool to the work surface.
2. Apply minimum pressure to work
surface, allowing the tool to operate at
high speed. Sanding rate is greatest
when the tool operates at high speed.
3. Figure M - Maintain a 5˚ to 15˚ angle
between the tool and work surface. The
san ding disc should contact
approximately one inch (25mm) of work
surface.

4. Move the tool constantly in a straight
line to prevent burning and swirling of
work surface. Allowing the tool to rest on
the work surface without moving, or
moving the tool in a circular motion
causes burning and swirling marks on
the work surface.
5. Remove the tool from work surface
before turning tool off. Allow the tool to
stop rotating before laying it down.
