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
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.
