MOUNTING TYPE 1 OR TYPE 41 CUI-FING WHEELS

_, CAUTION: Matching diameter backing flange and threaded locking
flange (included with tool) must be used for Type 1 and Type 41
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 locking flange with the raised section (pilot)
facing away from the wheel.
4. Depress the spindle lock button and tighten threaded locking
flange with a wrench.
5. To remove the wheel, depress the spindle lock button and loosen
the threaded locking flange with a wrench.
USING TYPE 1 OR TYPE 41 CUl-FING 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.
