Surface Grinding, Sanding and Wire
Brushing (Fig.O)

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.
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.
Spindle Lock (Fig.N)
The spindle lock button
3
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 has come to a completestop.
On/Off Switch (Fig.M)

WARNING: Do not switch the tool off while
underload.

CAUTION: Hold the auxiliary handle and body of the
tool firmly to maintain control of the tool at start up
and during use and until the wheel or accessory stops
rotating. Make sure the wheel has come to a complete
stop be fore laying the tooldown.

CAUTION: Allow the tool to reach full speed before
touching tool to the work surface. Lift the tool from the
work surface before turning the tool off.
