Mounting Guard
MOUNTING AND REMOVING GUARD (FIG. 4, 5)
CAUTION: Guards must be used with all grinding wheels,
sanding flap discs, wire brushes, and wire wheels. The tool may
be used without a guard only when sanding with conventional
sanding discs. Some D WALT models are provided with a guard
E
intended for use with depressed center wheels (Type 27) and hubbed
grinding wheels (Type 27). The same guard is designed for use with
sanding flap discs (Type 27 and 29) and wire brushes. Grinding and
cutting with wheels other than Type 27 and 29 require different
accessory guards not included with tool. Mounting instructions for
these accessory guards are included in the accessory package.
1. Open the guard latch (M). Align the lugs (N) on the guard with the
slots (O) on the gear case.

2. Push the guard down until the guard lugs engage and rotate freely
in the groove on the gear case hub.
3. With the guard latch open, rotate the guard (I) into the 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. You
should not be able to rotate the guard by hand when the latch
is closed. Do not operate the grinder with a loose guard or the
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
diameter of the gear case hub at the factory.
If, after a period of time, the guard becomes
loose, tighten the adjusting screw (P) with
clamp lever in the closed position.
CAUTION: Do not tighten the adjusting screw with the clamp lever
in open position. Undetectable damage to the guard or the mounting
hub may result.
CAUTION: If guard cannot be tightened by adjusting clamp, do
not use tool and take the tool and guard to a service center to repair
or replace the guard.
OPERATION
WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. Before
I
reconnecting the tool, depress and release the trigger switch
to ensure that the tool is off. An accidental start-up can cause
injury.
Guards and Flanges
It is important to choose the correct guards and flanges to use with
the grinder accessories. See pages 9–10 and this page for the correct
accessories.
NOTE: Edge grinding and cutting can be performed with Type 27
wheels designed and specified for this purpose.
