surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting it down.

WARNING: Before connecting the tool to a power
supply, be sure the slider switch is in the off position
by pressing the rear part of the switch and releasing.
Ensure the slider switch is in the off position as
described above after any interruption in power
supply to the tool, such as the activation of a ground
fault interrupter, throwing of a circuit breaker,
accidental unplugging, or power failure. If the slider
switch is locked on when the power is connected, the
tool will start unexpectedly.
To start the tool, slide the ON/OFF slider switch
the front of the tool. To stop the tool, release the ON/OFF
slider switch.
For continuous operation, slide the switch toward the front
of the tool and press the forward part of the switch inward.
To stop the tool while operating in continuous mode, press
the rear part of the slider switch and release.
Spindle Lock (Fig. A)
The spindle lock is provided to prevent the spindle from
2
rotating when installing or removing wheels. Operate the
spindle lock only when the tool is turned off, unplugged
from the power supply, 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. I)

CAUTION: Always use the correct guard per the
instructions in this manual.

WARNING: Metal dust build-up. Extensive use
of flap discs in metal applications can result in the
increased potential for electric shock. To reduce
this risk, insert an RCD before use and clean the
ventilation slots daily by blowing dry compressed air
into the ventilation slots inaccordance with the below
maintenance instructions.
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.

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.
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.
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:
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.
1. Paint should be removed in such a manner as to
minimize the amount of dust generated.
