WARNING: A closed, two-sided cutting wheel guard is included with this tool and
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. See pages 12 and
13 for more information.
MOUNTING CLOSED (TYPE 1) GUARD (FIG. 17)
WARNING: To reduce the risk of serious personal injury, turn tool off and
remove the battery pack before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.
1. Open the guard latch (V), and align the lugs (T)
on the guard with the slots on the hub (U).
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 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 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 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 (W) with the clamp lever in the
closed position with guard installed on the tool
(Fig. 18).
NOTICE: To reduce the risk of damage to the tool, do not tighten adjusting screw
with clamp lever in open position. Undetectable damage to guard or mounting hub
may result.
MOUNTING CUTTING WHEELS
WARNING: To reduce the risk of serious personal injury, turn tool off and
remove the battery pack before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.
CAUTION: Matching diameter threaded backing flange and clamp nut (included
with tool) must be used for cutting wheels.
FIG. 17
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
U
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, depress the spindle lock button and loosen the threaded
clamp nut with a wrench.
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.
I
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.
FIG. 18
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
W
rotating before setting it down.
