ENGLISH
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.
Using Cutting (Type 1) Wheels
WARNING: Do not use edge grinding/
cutting wheels for surface grinding
applications because these wheels
are not designed for side pressures
encountered with surface grinding.
Wheel breakage and injury may result.
1. Allow tool to reach full speed before touching
tool to work surface.
2. Apply minimum pressure to work surface,
allowing tool to operate at high speed. Cutting
rate is greatest when the tool operates at high
speed.
3. Once a cut is begun and a notch is established
in the workpiece, do not change the angle
of the cut. Changing the angle will cause the
wheel to bend and may cause wheel breakage.
4. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating
before setting it down.
Precautions To Take When Wire
Brushing Paint
1. Wire brushing of lead based paint is NOT
RECOMMENDED due to the difficulty of
controlling the contaminated dust. The greatest
danger of lead poisoning is to children and
pregnant women.
2. Since it is difficult to identify whether or not a
paint contains lead without a chemical analysis,
we recommend the following precautions when
wire brushing any paint:

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.
