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

time, the guard becomes loose, tighten the adjusting
screw (n) with the clamp lever in the closed position
with guard installed on the tool.

damage to the tool, do not tighten
adjusting screw (n) with clamp lever in
open position. Undetectable damage to
guard or mounting hub may result.

2. Place the wheel on the backing flange,
centering the wheel on the raised centre.
3. Install the threaded clamp nut with the raised
centre away from the wheel.
4. Depress the spindle lock button (c) and tighten
