Edge Grinding and Cutting (Fig. J)

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.
Surface Grinding, Sanding and Wire Brushing

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 in accordance 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.
Angle
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.
Spindle Lock (Fig.I)
The spindle lock
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.
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.
switch is locked on, the tool will start unexpectedly when it
isreconnected.
NOTE: To reduce unexpected tool movement, do not
switch the tool on or off while under load conditions. Allow
the grinder to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting itdown.
1. To turn the tool on, push the lock-off lever
2
toward the
back of the tool, then depress the paddle switch
1
. The tool
will run while the switch isdepressed.
2. Turn the tool off by releasing the paddleswitch.
- 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 cleanup 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.
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.
During cleanup, children and pregnant women should be
kept away from the immediate workarea.
3. All toys, washable furniture and utensils used by children
should be washed thoroughly before being usedagain.
