use proper flange and guard can result in injury resulting from
wheel breakage and wheel contact. See pages 10 and 11 for more
information.
MOUNTING CLOSED (TYPE 1) GUARD
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
1. Open the guard latch (J), and align the
arrow on the guard (K) with the arrow on
the hub (L). This will align the 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 (I) into desired working posi-
tion. 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
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: The guard is pre-adjusted to the diameter of the gear case
hub at the factory. If, after a period of time, the guard becomes
loose, tighten the adjusting screw (M) with the clamp lever in the
closed position with guard installed on the tool.
CAUTION: Do not tighten adjusting screw with clamp lever in
open position. Undetectable damage to guard or mounting hub
may result.
MOUNTING CUTTING WHEELS
CAUTION: Turn off tool and remove battery before making
any adjustments or removing or installing attachments or
accessories.
J
CAUTION: Matching diameter threaded 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
L
the backing flange will be against the wheel when the wheel
is installed.
K
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.
I
5. To remove the wheel, grasp and turn while depressing the spin-
dle lock button.
USING CUTTING WHEELS
WARNING: Do not use edge grinding/cutting wheels for surface
grinding applications because these wheels are not designed for
M
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 oper-
ate at high speed. Cutting rate is greatest when the tool oper-
ates at high speed.
