Using sanding backing pads (fig. H)
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.
u
Medium = 36 - 80 grit.
u
Fine Finishing = 100 - 120 grit.
u
Very Fine Finishing = 150 - 180 grit.
u
Allow the tool to reach full speed before touching tool to
u
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 figure H. 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:
No children or pregnant women should enter the work
u
area where the paint sanding is being done until all
clean up is completed.
A dust mask or respirator should be worn by all
u
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
u
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
u
minimize the amount of dust generated.
10
Areas where paint removal is occurring should be
u
sealed with plastic sheeting of 4 mils thickness.
Sanding should be done in a manner to reduce tracking
u
of paint dust outside the work area.
All surfaces in the work area should be vacuumed and
u
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
u
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
u
children should be washed thoroughly before being
used again.
Fitting and using wire brushes and wire wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. A Type 27 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 figure I.
● Maintain contact between the edge of the wheel and the
work surface with wire wheels.
● 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.
● Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before setting
it down.
