CAUTION: Matching diameter threaded backing flange and clamp
nut (included with tool) must be used for cutting wheels.
1. Place the unthreaded backing flange on spindle with the raised
section (pilot) facing up. The raised section (pilot) on the backing
flange will be against the wheel when the wheel is installed.
2. Place the wheel on the backing flange, centering the wheel on the
raised section (pilot).
3. Install the threaded clamp nut with the raised section (pilot)
facing away from the wheel.
4. Depress the spindle lock button and tighten clamp nut with a
wrench.
5. To remove the wheel, grasp and turn while depressing the
spindle lock button.
USING CUTTING WHEELS (FIG. 18)
WARNING: Do not use
grinding/cutting wheels for surface grinding
applications because these wheels are not
designed for side pressures encountered
with surface grinding. Wheel breakage and
injury may result.
1. Allow tool to reach full speed before
touching tool to work surface.
2. Apply minimum pressure to work
surface, allowing tool to operate at
high speed. Cutting rate is greatest
when the tool operates at high speed.
3. 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.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.

WARNING: To reduce the risk of injury, turn unit off and
disconnect tool from power source before installing and
