MOUNTING CLOSED (TYPE 1) GUARD
WARNING: To reduce the risk of serious personal injury, turn
tool off and and remove battery pack before making any adjust-
ments or removing/installing attachments or accessories.
1. Open the guard latch (R), and align
the lugs (S) on the guard with the slots
on the hub (T). 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 fac-
tory. If, after a period of time, the guard
becomes loose, tighten the adjusting
screw (V) with the clamp lever in the
closed position with guard installed on the
tool.
CAUTION: To reduce the risk of damage to the tool, do not tight-
en 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
T
tool off and and remove battery pack before making any adjust-
ments or removing/installing attachments or accessories.
CAUTION: Matching diameter threaded backing flange and
clamp nut (included with tool) must be used for cutting wheels.
S
1. Place the unthreaded backing flange on spindle with the
R
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.
I
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.
1. Allow tool to reach full speed before touching tool to work
surface.
V
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.
