Mounting and Using Cutting (Type 1)
Wheels
Cutting wheels include diamond wheels and abrasive discs.
Abrasive cutting wheels for metal and concrete use are available.
Diamond blades for concrete cutting can also be used.
WARNING: A closed, cutting wheel guard is not included with this
tool. Cutting wheels require proper flanges and guards. A 7" cutting
guard, D284931, is available as an accessory and includes proper,
matching flanges. Failure to use proper flange and guard can result
in injury resulting from wheel breakage and wheel contact.
MOUNTING CLOSED (TYPE 1) GUARD
Turn off and unplug tool before making any adjustments or
removing or installing accessories. Before reconnecting the
tool, depress and release the trigger switch to ensure that the
tool is off.
1. Open the guard latch (H), and align the lugs with slots on the
gear case cover. Position the guard facing backward, as shown.
2. Push the guard down until the guard lug engages and rotates
freely in the groove on the gear case hub.

3. Rotate guard (Q) into desired working posi-
tion. The guard body should be positioned
between the spindle and the operator to pro-
vide maximum operator protection.
4. Close the guard latch to secure the guard on
the gear case cover. You should be unable to
5˚-10˚
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 posi-
tion.
NOTE: The guard is pre-adjusted to the dia-
meter of the gear case hub at the factory. If,
after a period of time, the guard becomes
loose, tighten the adjusting screw (I) with the
clamp lever in the closed position.
CAUTION: Do not tighten adjusting screw
with clamp lever in open position. Undetectable
damage to guard or mounting hub may result.
