Mounting Type 1/Type 41
Cutting Wheels (Fig. 13)
CAUTION: The 1-11/16" (43 mm) diameter backing flange and
threaded locking flange (included with tool) must be used for Type 1
and Type 41 cutting wheels.
Cutting wheels include diamond wheels and abrasive discs. Abrasive
cutting wheels for metal and concrete use are available. Diamond
blades for concrete cutting can also be used.
1. Depress wheel change release
button and hinge open the top
half of the guard to the farthest
open position. Refer to figure 3.
2. Press the unthreaded backing
flange (I) onto spindle with raised
section (pilot) facing up until it
seats fully against gear case.
The raised section (pilot) on the
backing flange will fit the center

USING TYPE 1 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.
