3. Keeping the guard release lever open, push the guard down until
the guard lugs engage and rotate them in the groove on the gear
case hub. Release the guard release lever.
4. With the spindle facing the operator, rotate the guard clockwise
into the desired working position. The guard body should be
positioned between the spindle and the operator to provide
maximum operator protection.
5. For easy adjustment, the guard can be rotated in the clockwise
direction.
NOTE: The guard release lever should snap into one of the
alignment holes (O) on the guard collar. This insures that the guard
is secure. The guard can be repositioned the opposite direction
by depressing the guard release lever.
6. To remove the guard, follow steps 1–3 of these instructions in
reverse.
MOUNTING TYPE 1 OR TYPE 41 CUTTING WHEELS
WARNING: To reduce the risk of serious personal injury,
turn tool off before making any adjustments or removing/
installing attachments or accessories. An accidental start-up can
cause injury.
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 in the center hole of 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 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.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. An
accidental start-up can cause injury.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air
at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
