DeWalt DW400 Mounting and Using Wire Brushes and Wire Wheels, Environmental Safety

ENVIRONMENTAL SAFETY

1.Paint should be removed in such a manner as to minimize the amount of dust generated.

2.Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils thickness.

3.Sanding should be done in a manner to reduce tracking of paint dust outside the work area.

CLEANING AND DISPOSAL

1.All surfaces in the work area should be vacuumed and thor- oughly cleaned daily for the duration of the sanding project. Vacuum filter bags should be changed frequently.

2.Plastic drop cloths should be gathered up and disposed of along with any dust chips or other removal debris. They should be placed in sealed refuse receptacles and disposed of through regular trash pick-up procedures.

During clean up, children and pregnant women should be kept away from the immediate work area.

3.All toys, washable furniture and utensils used by children should be washed thoroughly before being used again.

Mounting and Using Wire Brushes and Wire Wheels

Wire cup brushes or wire wheels screw directly on the grinder spindle without the use of flanges. Use only wire brushes or wheels provided with a 5/8" – 11 threaded hub. A Type 27 guard is required when using wire brushes and wheels.

CAUTION: Wear work gloves when handling wire brushes. Wire brushes can become sharp.

MOUNTING WIRE BRUSHES AND WIRE WHEELS

CAUTION: Turn off and unplug the tool before making any adjustments or removing or installing attachments or acces-

sories. Before reconnecting the tool, actuate and release switch to ensure that the tool is off.

1.Thread the wheel on the spindle by hand.

2.Depress spindle lock button and use a wrench on the hub of the wire wheel or brush to tighten the wheel.

3.To remove the wheel, reverse the above procedure.

CAUTION: Failure to properly seat the wheel hub before turning the tool on may result in damage to tool or wheel.

USING WIRE BRUSHES AND WIRE WHEELS

Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.

NOTE: The same precautions should be taken when wire brushng paint as when sanding paint (see page 10).

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to work surface, allowing the tool to operate at high speed. Material removal rate is greatest when the tool operates 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	5˚-10˚
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.
