DeWalt D28490 Manual De Instrucciones página 35

Wire brushes and wire wheels must be rated above minimum
accessory speed as shown on tool. Use only wire brushes and
wheels provided with a 5/8"–11 or M14 threaded hub. A type 27
guard is required when using wire brushes and wheels.
CAUTION: Wear work gloves when handling wire brushes or
wheels. Wire brushes and wheels can become sharp.
MOUNTING WIRE BRUSHES AND WIRE WHEELS
1. Thread the wheel on the spindle by hand, seating the wheel
against the mount.
2. Depress the spindle lock button and use a wrench on the hub of
the wire brush or wheel to tighten the wheel.
3. To remove the wheel, depress the spindle lock button and use a
wrench on the hub of the wire brush or wheel to loosen it.
NOTE: Failure to properly seat the wheel hub against the mount
before turning the tool on may result in damage to the tool or wheel.
USING WIRE CUP BRUSHES AND WIRE WHEELS
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
1. Allow tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, to allow the tool to
operate at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool and work surface for
wire cup brushes.
4. Maintain contact between the edge of the wheel and the work
surface with wire wheels.
5. Continuously move the tool in a forward and back motion to avoid
creating gouges in the work surface. Allowing the tool to rest on
the work surface without moving, or moving the tool in a circular
motion causes burning and swirling marks on the work surface.
6. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before setting it down.
Mounting and Using Flaring Cup
(Type 11) Wheel
MOUNTING FLARING CUP WHEEL GUARD

(102 mm) flaring cup wheel guard and 6" (152 mm) flaring cup wheel
guard are available as accessories and include proper flange. Failure
to use the proper flange and guard can result in injury resulting from
wheel breakage and wheel contact.
WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off. An
accidental start-up can cause injury.
1. Install the guard as shown.
2. Guard body should be positioned between the spindle and the
operator to provide maximum operator protection.
