Surface Finishing with Sanding Discs (Fig. H)
• Allow the tool to reach full speed before touching the tool to
the work surface.
• 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.
• Maintain a 5˚ to 10˚ angle between the tool and work surface
as shown in Fig. H.
• Continuously move the tool in a forward and back motion to
avoid creating gouges in the work surface.
• Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying it down.
Using Sanding Backing Pads (Fig. I)
Always 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.
- Coarse = 16–30 grit.
- Medium = 36–80 grit.
- Fine Finishing = 100–120 grit.
- Very Fine Finishing = 150–180 grit.
- Allow the tool to reach full speed before touching tool to the
work surface.
• 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.
• Maintain a 5˚ to 10˚ angle between the tool and work
surface as shown in Fig. I. The sanding disc should contact
approximately 25mm of work surface.
• 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.
• Remove the tool from work surface before turning tool off.
Allow the tool to stop rotating before laying it down.
Precautions to Take when Sanding Paint
• Sanding 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.
• 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:
onto the backing pad.

- No children or pregnant women should enter the work
area where the paint sanding is being done until all clean up
is completed.
- 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 approved mask.
- 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.
- Paint should be removed in such a manner as to minimize the
amount of dust generated.
- Areas where paint removal is occurring should be sealed with
plastic sheeting of 4 mils thickness.
- Sanding should be done in a manner to reduce tracking of
paint dust outside the work area.
- 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.
- 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.
- All toys, washable furniture and utensils used by children
should be washed thoroughly before being used again.
Fitting and Using Wire Brushes and Wire Wheels (Fig. J)
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. A Type C guard is required
when using wire brushes and wheels. Wear work gloves when
handling wire brushes and wheels. They can become sharp.
Wheel or brush must not touch guard when mounted or while
in use. Undetectable damage could occur to the accessory,
causing wires to fragment from accessory wheel or cup.
• Thread the wheel on the spindle by hand.
• Depress spindle lock button and use a wrench on the hub of
the wire wheel or brush to tighten the wheel.
• To remove the wheel, reverse the above procedure.
WARNING! Failure to properly seat the wheel hub before
turning the tool on may result in damage to tool or wheel. 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.
• Allow the tool to reach full speed before touching the tool to
the work surface.
• 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.
• Maintain a 5˚ to 10˚ angle between the tool and work surface
for wire cup brushes as shown in Fig. J.
• Maintain contact between the edge of the wheel and the
work surface with wire wheels.
