Operation (Fig. 9)
To operate your sander, grasp it as shown in Figure 9 and turn it on. Move it in long, sweeping
strokes along the surface being sanded, letting it do the work. Pushing down on the tool while
sanding actually slows the removal rate and produces an inferior quality surface. Be sure to check
your work often, this sander is capable of removing material rapidly, especially with coarse paper.
Your sander is designed to sand flush on three sides (four sides without the dust collection bag)
for sanding in corners, and its small size and light weight make it ideal for overhead work.
The orbital action of your sander allows you to sand with the grain or at any angle across it for
most sanding jobs. On the final sanding steps, as discussed below, a better finish will result if
you sand only with the grain.
To produce the best finish possible, start with coarse grit sandpaper and change gradually to
finer and finer paper. A final sanding with a piece of well worn fine sandpaper will produce a real-
ly professional looking finish that in many cases will need no hand sanding at all. The rate at
which the dust collection bag will fill up will vary with the type of material being sanded and the
coarseness of the sandpaper. For best results, empty the bag frequently and check the opening
for clogging.
When sanding painted surfaces, you may find that the sandpaper loads up and clogs with paint.
A heat gun will work much better to remove paint before sanding. FOLLOW ALL SAFETY
INSTRUCTIONS IN HEAT GUN INSTRUCTION MANUAL.
Precautions To Take When Sanding Paint
1. 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.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical analy-
sis, we recommend the following precautions when sanding any paint:
PERSONAL SAFETY
a. No children or pregnant women should enter the work area where the paint sanding is
being done until all clean up is completed.
b. 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 deal-
er for the proper N.I.O.S.H. approved mask.
c. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingest-
ing 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
a. Paint should be removed in such a manner as to minimize the amount of dust generated.
b. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mils
thickness.
c. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
CLEANING AND DISPOSAL
a. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the dura-
tion of the sanding project. Vacuum filter bags should be changed frequently.
b. 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.
c. All toys, washable furniture and utensils used by children should be washed thoroughly
before being used again.
Tool Care
Keep your machine as clean as possible by wiping with a clean cloth and blowing through it with
air after every 5 hours of use.
Don't use harsh chemicals or solvents to clean the tool. These chemicals could seriously dam-
age the plastic.
Avoid overloading your sander. Overloading will result in a considerable reduction in speed and
efficiency and the unit will become hot. In this event, run sander at a "no load" condition for a
minute or two.
Brush Replacement (Fig 10 & 11)
TURN OFF AND UNPLUG THE SANDER
To replace the tool's brushes, remove the three screws located in the top cap, as shown in
Figure 10.
Lift off the top cap. Observe the brush holders, as shown in Figure 11 and the wires leading from
the brushes to the motor field.
Pull the wires from the motor field and then lift and hold out of the way one of the brush springs.
Remove the old brush from the brush holder and discard the brush/wire assembly. Still holding
the brush spring out of the way, insert the new brush, release the spring against the back of the
brush and plug the wire into the motor field. Repeat the procedure for the second brush.
Replace the top cap and tighten the three screws that hold it in place. (Always replace both
brushes.)
