PERSONAL SAFETY
1. No children or pregnant women should enter
the work area where the paint removal is being
done until all clean up is completed.
2. A dust mask or respirator should be worn by
all persons entering the work area. The filter
should be replaced daily or whenever the
wearer has difficulty breathing.
NOTE: Only those dust masks suitable for
working with lead paint dust and fumes should
be used. Ordinary painting masks do not offer
this protection. See your local hardware dealer
for the proper respiratory protection.
3. NO EATING, DRINKING or SMOKING should
be done in the work area to prevent ingesting
contaminated paint particles. Workers should
wash and clean up BEFORE eating, drinking
or smoking. Articles of food, drink, or smoking
should not be left in the work area where dust
would settle on them.
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. 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.
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 an 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 in the 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.

Cutting Metal

When cutting, work with moderate feed, adapted to
the material being cut. Do not exert pressure onto
the cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.
The machine must always work in an upgrinding
motion. Otherwise, the danger exists of it being
pushed uncontrolled out of the cut.
When cutting profiles and square bar, it is best to
start at the smallest cross section.
Rough Grinding
Never use a cutting disc for roughing.
Always use the guard type 27.
The best roughing results are achieved when setting
the machine at an angle of 30° to 40°. Move the
machine back and forth with moderate pressure. In
this manner, the workpiece will not become too hot,
does not discolour and no grooves are formed.
Cutting Stone
The machine shall be used only for dry cutting.
For cutting stone, it is best to use a diamond
cutting disc. Operate the machine only with
additional dust protection mask.

Working Advice

Exercise caution when cutting slots in
structural walls. Slots in structural walls are
subject to the country-specific regulations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architect or the
construction supervisor.
Using Flap Discs
WARNING: Metal dust build-up.
Extensive use of flap discs in metal
applications can result in the increased
potential for electric shock. To reduce
this risk, insert an RCD before use and
clean the ventilation slots daily by blowing
