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.
MOUNTING CUTTING WHEELS (FIG. 1, 4)
CAUTION: Matching diameter backing
flange and clamp nut (included with

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.

Prior to Operation
• Install the guard and appropriate disc or wheel.
Do not use excessively worn discs or wheels.
• Be sure the inner and outer flange are mounted
correctly. Follow the instructions given in the
Grinding and Cutting Accessory Chart.
• Make sure the disc or wheel rotates in the
direction of the arrows on the accessory and
the tool.
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad
for cracks, tear or excess wear, wire brush
for loose or cracked wires. If power tool or
accessory is dropped, inspect for damage
or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool
at maximum no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
