3. While depressing the spindle lock button, thread the
clamp nut (G) on spindle. If the wheel you are
installing is more than 3.18 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 3.18 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.
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.

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 9 for more
information. Type 1 guards are available at extra cost
from your local dealer or authorized service center.

applications because these wheels are not designed for side pressures encountered
with surface grinding. Wheel breakage and injury may result.

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.
3. Position yourself so that the open-underside of the wheel is facing away from
you.
4. Once a cut is begun and a notch is established in the workpiece, do not change
the angle of the cut. Changing the angle will cause the wheel to bend and may
cause wheel breakage. Edge grinding wheels are not designed to withstand side
pressures caused by bending.
5. Remove the tool from the work surface before turning the tool off. Allow the tool
to stop rotating before laying it down.
WARNING: Do not use edge grinding/cutting wheels for surface grinding
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.
