MOUNTING CLOSED (TYPE 1) GUARD
1. Open the guard latch (M), and align the
lugs (N) on the guard with the slots on
the hub (O). 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 (F) 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 (P) with
the 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.

USING CUTTING WHEELS
P
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.
