4. Continuously move the tool in a forward and back
motion to avoid creating gouges in the work surface.
5. Remove the tool from work surface before turning
tool off. Allow the tool to stop rotating before setting
it down.
Mounting and Using Cutting
(Type 1) Wheels (Fig. S, T)
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, two-sided cutting wheel guard
is re quired when using cutting wheels. Fail ure to use
proper flange and guard can re sult in injury resulting
from wheel breakage and wheel contact. Refer to the
Accessories Chart for more information.
Mounting Closed (Type 1) guard
1. Open the guard latch
guard with the slots on the hub
lugs with slots on the gear case cover. Position the guard
facing backward.

2. Push the guard down until the guard lug engages and
rotates freely in the groove on the gear case hub.
3. Rotate guard

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. Do not
operate grinder with a loose guard or with the guard
latch in open position.
5. To remove the guard, follow the procedure above in
reverse order.
NoTE: The guard is pre-adjusted to the dia met er of the gear
case hub at the factory. If, after a period of time, the guard
becomes loose, tighten the adjusting screw
guard latch in the closed position with guard installed on
the tool.

NOTICE: To reduce the risk of damage to the tool, do
not tighten adjusting screw with guard latch in open
position. Undetectable damage to guard or mounting
hub may result.
Mounting Cutting Wheels (Fig. U)
CAUTION: Matching diameter backing flange and
clamp nut (included with tool) must be used for
cutting wheels.
1. Remove soft mount
2. Install wheel backing flange, aligning flats on spindle

with flats on backing flange
3. Place the wheel on the backing flange, centering the
wheel on the backing flange pilot.
4. Install the clamp nut, ensuring that the wheel remains
centered on the backing flange.
5. Depress the spindle lock button and tighten clamp nut
with wrench.
6. Reverse the above procedure to remove the wheel.

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 wheel to stop rotating before laying the
tool down.
