
WARNING: Before connecting the tool to a power supply,
be sure the slider switch is in the off position. Ensure the
slider switch is in the off position 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 slide switch

ALWAYS hold securely in anticipation of a suddenreaction.
Proper hand position requires one hand on the main
handle
24
and the other hand on the auxiliary handle
6
, as
shown in Fig.I.
Variable Speed Dial (Fig.J)

WARNING: Rated speed of accessory must be at least
equal to the maximum speed marked on the power tool.
The variable speed dial
11
offers added tool control and
enables the tool to be used at optimum conditions to suit
the application.
• Turn the variable speed dial
11
to the desired level.
Turn the dial upward for higher speed and downward for
lowerspeed.
Spindle Lock (Fig.K)
The spindle lock button
4
is provided to prevent the
spindle from rotating when installing or removing wheels.
Operate the spindle lock only when the tool is turned off,
the battery is removed and the spindle 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.
Function Angle
Grinding 20˚-30˚
Sanding with Flap Disc 5˚-10˚
Sanding with Backing Pad 5˚-15˚
Wire Brushing 5˚-10˚
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workpiece.
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.
