2. Areas where paint removal is occurring should
be sealed with plastic sheeting of 4 mils
thickness.
3. Wire brushing 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 thoroughly cleaned daily for the
duration of the wire brushing 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 M14
threaded hub. A Type 27 guard is required when
using wire brushes and wheels.
CAUTION: To reduce the risk of
personal injury, wear work gloves
when handling wire brushes and
wheels. They can become sharp.
CAUTION: To reduce the risk of
damage to the tool, wheel or brush
must not touch guard when mounted
or while in use. Undetectable damage
could occur to the accessory, causing
wires to fragment from accessory wheel
or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
WARNING: To reduce the risk of
serious personal injury, turn tool off
and and remove battery pack before
making any adjustments or removing/
installing attachments or accessories.
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.
NOTICE: To reduce the risk of
damage to the tool, properly seat the
wheel hub before turning the tool on.
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 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 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.
CAUTION: Use extra care when
working over an edge, as a sudden
sharp movement of grinder may be
experienced.
Metal Applications
When using the tool in metal applications, make
sure that a residual current device (RCD) has been
inserted to avoid residual risks caused by metal
swarf.
If the power supply is shut off by the RCD, take the
tool to authorised D WALT repair agent.

WARNING: In extreme working
conditions, conductive dust can
accumulate inside the machine housing
when working with metal. This can result
in the protective insulation inthe machine
becoming degraded with a potential risk
of an electrical shock.
To avoid build-up of metal swarf inside the machine,
we recommend to clear the ventilation slots on a
daily basis. Refer to Maintenance.
