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
WARNING: Turn off and unplug the tool before making
any adjustments or removing or installing attachments or
accessories. Before reconnecting the tool, turn the switch
on and off as previously described to ensure that the tool is
off.
Depressed center Type 27 grinding wheels must be used
with included flanges. See page 8 of this manual for more
information.
1. Install the unthreaded backing flange (G) on spindle
(D) 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 3.2 mm (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 3.2 mm (1/8") thick or less, place the
threaded clamp nut on the spindle so that the raised section (pilot) is not against
the wheel.

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
G
the wheel, it will spin because the height of the pilot prevents the clamp nut from
holding the wheel.

may break 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, limit the use of these wheels with a
standard Type 27 guard to shallow cutting and notching
[less than 13 mm (1/2") in depth]. The open side of the
guard must be positioned away from the operator. For
deeper cutting with a Type 1 cut-off wheel, use a closed,
Type 1 guard. See the chart on page 8 for more

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.
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. 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.
CAUTION: Wheels used for cutting and edge grinding
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.
