DeWalt DWE4011 Guide D'utilisation page 11

Threaded accessories must have a 5/8"–11 hub. Every unthreaded
accessory must have a 7/8" arbor hole. If it does not, it may have
been designed for a circular saw and should not be used. Use only
the accessories shown in the Accessories Chart of this manual.
Accessory ratings must be above listed minimum wheel speed as
shown on tool nameplate.
WARNING: Handle and store all abrasive wheels carefully to
prevent damage from thermal shock, heat, mechanical damage,
etc. Store in a dry protected area free from high humidity, freezing
temperatures or extreme temperature changes.
Mounting Guard
CAUTION: Guards must be used with all grinding wheels,
cutting wheels, sanding flap discs, wire brushes, and wire
wheels. The tool may be used without a guard only when sanding
with conventional sanding discs. A Type 1 guard (intended for use with
Type 1 cutting wheels and Type 27 wheels marked for cutting only)
is available at extra cost from your local dealer or authorized service
center. Grinding with wheels other than Type 27 and Type 29 require
different accessory guards not included with the tool. A type 27 guard
is provided for use with a 1/4" (6.35 mm) thick Type 27 wheel.
MOUNTING AND REMOVING (TYPE 27)
ONE-TOUCH™ GUARD (FIG. 4, 5)
NOTE: If your grinder is supplied with a
keyless ONE TOUCH™ guard, ensure the
screw, lever, and spring are fitted correctly
before mounting the guard.
1. Press and hold the guard release lever (H).
2. Align the lugs (I) on the guard with the slots
on the gear case (J).
3. Push the guard down until engage the lugs and rotate them into
the groove on the gear case hub. Release the guard release lever.
4. With the spindle facing the operator, rotate
the guard clockwise into the desired
working position. The guard body should
be positioned between the spindle and the
operator to provide maximum operator
protection.
5. For easy adjustment, the guard can
be rotated in the clockwise direction.
NOTE: The guard release lever should
snap into one of the alignment holes (K)
on the guard collar. This insures that the guard is secure. The
guard can be repositioned the opposite direction by depressing
the guard release lever.
6. To remove the guard, follow steps 1–3 of these instructions in
reverse.
NOTE: Edge grinding and cutting can be performed with
Type 27 wheels designed and specified for this purpose; 1/4"
(6.35 mm) thick wheels are designed for surface grinding while 1/8"
(3.17 mm) wheels are designed for edge grinding. Cutting can also be
performed by using a Type 1 wheel and a Type 1 guard.
NOTE: See the Accessories Chart to select the proper guard /
