WARNING: A closed, two-sided cutting
wheel guard is re quired when using
cutting wheels. These accessories are
available at extra cost from your local
dealer or authorised service centre.

the tool is off.
MOUNTING CLOSED (TYPE 1) GUARD (FIG. 5)
1. Open the guard latch (k), and align the lugs (l)
on the guard with the slots on the gear case
(m). 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 (n) with the clamp lever 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 (n) with clamp lever in
open position. Undetectable damage to
guard or mounting hub may result.

raised centre on the backing flange will be
against the wheel when the wheel is installed.
2. Place the wheel on the backing flange,
centreing 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
clamp nut with a wrench.
5. To remove the wheel, depress the spindle lock
button and loosen the threaded clamp nut with
a wrench.
