2. Apply minimum pressure to the work surface, allowing the
tool to operate at high speed. Grinding rate is greatest when
the tool operates at high speed.
3. Position yourself so that the open-underside of the wheel is
facing away from you.
4. 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. Edge grinding wheels are not designed to
withstand side pressures caused by bending.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
it down.

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 serious personal injury
may result.
Mounting and 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: Please refer to Precautions To Take When Wire
Brushing Paint.
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.
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.

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.
