3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particular function.
Function
Grinding
Sanding with Flap Disc
Sanding with Backing Pad
Wire Brushing
4. Maintain contact between the edge of the wheel and the
work surface.
If grinding, sanding with flap discs or wire brushing
-
move the tool continuously in a forward and back
motion to avoid creating gouges in the work surface.
-
If sanding with a backing pad, move the tool
constantly in a straight line to prevent burning and
swirling of work surface.
NoTE: Allowing the tool to rest on the work surface without
moving will damage the work piece.
5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying it down.
CAUTION: Use extra care when working over an
edge, as a sudden sharp movement of grinder may
be experienced.
Precautions To Take When Working on a
Painted Workpiece
1. Sanding or 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 sanding
any paint:
personal safety
1. No children or pregnant women should enter the work
area where the paint sanding or wire brushing 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 N.I.O.S.H. approved mask.
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.
Angle
20˚-30˚
5˚-10˚
5˚-15˚
5˚-10˚
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 thoroughly 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.
Edge Grinding and Cutting
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.
CAUTION: Wheels used for edge grinding and
cutting may break or kick back if they bend or twist
while the tool is being used. In all edge grinding/
cutting operations, the open side of the guard must be
positioned away from the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel
must be limited to shallow cutting and notching—less
than 13 mm in depth when the wheel is new. Reduce
the depth of cutting/notching equal to the reduction
of the wheel radius as it wears down. Refer to the
Grinding and Cutting accessory Chart for more
information. Edge grinding/cutting with a Type 41
wheel requires usage of a Type 1 guard.
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting 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.
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.
