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 clean up, 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.
Edge Grinding
Edge grinding must not be done with this tool.
Using Sanding Backing Pads
Choose the proper grit sanding discs for your application.
Sanding discs are available in various grits. Coarse grits yield
faster material removal rates and a rougher finish. Finer grits
yield slower material removal and a smoother finish.
Begin with coarse grit discs for fast, rough material removal.
Move to a medium grit paper and finish with a fine grit disc
for optimal finish.

1. Allow the tool to reach full speed before touching tool
to the work surface.
2. Apply minimum pressure to work surface, allowing the
tool to operate at high speed. Sanding rate is greatest
when the tool operates at high speed.
3. Figure M - Maintain a 5˚ to 15˚ angle between the
tool and work surface. The san ding disc should contact
approximately 1" (25mm) of work surface.
4. Move the tool constantly in a straight line to prevent
burning and swirling of work surface. Allowing the tool
to rest on the work surface without moving, or moving
the tool in a circular motion causes burning and swirling
marks on the work surface.

5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying it down.
Using Wire Cup Brushes and Wire Wheels
Wire wheels and brushes can be used for removing rust,
scale and paint, and for smoothing irregular surfaces.
nOTE: The same precautions should be taken when wire
brushing paint as when sanding paint.
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to work surface, allowing the
tool to operate at high speed. Material removal rate is
greatest when the tool operates at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool and work
surface for wire cup brushes.
4. Maintain contact between the edge of the wheel and
the work surface with wire wheels.
5. Continuously move the tool in a forward and back
motion to avoid creating gouges in the work surface.
Allowing the tool to rest on the work surface without
moving, or moving the tool in a circular motion causes
burning and swirling marks on the work surface.
6. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before
setting it down.
7. Use extra care when working over an edge, as a sudden
sharp movement of grinder may be experienced.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can cause injury.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of
the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid
get inside the tool; never immerse any part of the tool
into a liquid.
Blowing dust and grit out of the motor housing using
compressed air is a necessary maintenance procedure. Dust
and grit from metal grinding often accumulate on interior
surfaces and could create an electrical shock hazard if not
cleaned out.
