Mounting and Using Cutting (Type 1) 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.
WARNING:
A closed, 2-sided cutting wheel guard is not included with this tool but
is required when using cutting wheels. Failure to use proper flange and guard can
result in injury resulting from wheel breakage and wheel contact. See page 8 for more
information.

and rotates freely in the groove on the gear case
hub.
3. Rotate guard (C) into desired working position.
The guard body should be positioned between
the spindle and the operator to provide maximum
operator protection.
4. Close the guard latch to secure the guard on the
gear case cover. You should be unable to rotate the
guard by hand when the latch is in closed position.

If rotation is possible, tighten the adjusting screw (M)
with clamp lever in the closed position. Do not
operate grinder with a loose guard or clamp lever in
open position.
5. To remove the guard, open the guard latch, rotate the
guard so that the arrows are aligned and pull
up on the guard.
NOTE:
If, after a period of time, the guard becomes loose, tighten the adjusting screw
(M) with the clamp lever in the closed position.
CAUTION:
Do not tighten adjusting screw with clamp lever in open position.
Undetectable damage to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
WARNING:
Turn off and unplug the tool before making any adjustments or
removing or installing attachments or accessories.
Before reconnecting the tool,
turn the switch on and off as previously described to ensure that the tool is off.
CAUTION:
Matching diameter unthreaded 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
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.
