Maintenance - DeWalt DC411-XE Instruction Manual

CAUTION: Matching diameter backing flange and threaded clamping 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, depress the spindle lock button and loosen the threaded
clamp nut with a wrench.
USING CUTTING WHEELS
WARNING: Do not use edge 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.
