Spindle Lock Button (Fig. K)
The spindle lock button is provided to prevent the
3
spindle from rotating when installing or removing wheels.
Operate the spindle lock only when the tool is turned off,
when the battery has been removed, and has come to a
complete stop.
NOTICE: To reduce the risk of damage to the tool, do
not engage the spindle lock while the tool is operating.
Damage to the tool will result and attached accessory
may spin off possibly resulting in injury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate the
spindle further.

Surface Grinding, Sanding and Wire
Brushing (Fig. L)

CAUTION: Always use the correct guard per the
instructions in this manual.
To perform work on the surface of a workpiece:
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. Material removal rate
is greatest when the tool operates at high speed.

3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particular function.

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 NIOSH-
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.
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.
