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.
If surface finishing, constantly move the tool

to achieve the proper finish and to prevent
overheating of the 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

Angle
1. Paint should be removed in such a manner as to
20˚-30˚
2. Areas where paint removal is occurring should be sealed

They should be placed in sealed refuse receptacles and

During clean up, children and pregnant women should

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 Accessories Chart for more information. Edge

Changing the angle will cause the wheel to bend and

by bending.
