How to Operate the Machine
DA N G E R: Sanding/finishing wood floors
can create an environment
that can be explosive. Cigarette lighters, pilot lights and
any other source of ignition
can create an explosion when
active during a sanding session. All sources of ignition
should be extinguished or
removed entirely if possible
from the work area.
DANGER: Work areas that are poorly
ventilated can create an
explosive environment when
certain combustible materials
are in the atmosphere, i.e.,
solvents, thinners, alcohol,
fuels, certain finishes, wood
dust and other combustible
materials. Floor sanding
machines can cause flammable material and vapors to
ignite. Read the manufacturer's label on all chemicals
used to determine combustibility. Keep the work area well
ventilated.
DAN G ER : Sanding dust can spontane-
ously ignite and cause an
injury or damage. Sanding
dust should be disposed of
properly. Always empty the
sanding dust into a metal
container. Remove the contents of the dust bag when the
bag is 1/3 full.
DAN G ER : Sanding dust can spontane-
ously ignite and cause an
injury or damage. Remove the
contents of the dust bag each
time you finish using the
machine. Always dispose of
the dust in a metal container
located outside of the building.
Never leave a dust bag unattended with sanding dust in it.
Do not empty the contents of
the dust bag into a fire.
DANGER: Hitting a nail while sanding
can cause sparks and create
an explosion or fire. Always
use a hammer and punch to
countersink all nails before
sanding floors.
To operate the machine follow this procedure:
1. Before sanding, decide on best approach for
sanding desired area. If the floor is uneven, it
may be necessary to sand diagonally to the
direction that the floor is laid. This will help
"pull" or stretch low and high spots in the floor
over a greater area, producing a flatter surface.
When sanding the area, work in a way so that
you are moving away from where the cord set
enters the room. This will help to avoid entanglement with the cord set and eliminate the need to
move the cord set out of the way so frequently.
Work the area in a way that avoids interruption or
termination points ( an end of pass.) Make long
continuous passes.
2. Swing cable arm to side of machine opposite the
direction you intend to work. Rotate elbow on
dust pipe until dust bag rest on motor. This will
maintain balance and sanding pressure as the
dust bag fills. The machine should be operated
with the dust bag in this position whenever
possible.
3. Install the operating belt as follows:
a. Position the operating belt around waist.
b. Cross the straps at the waist. See figure #9.
c. Slide the belt loop end over the handle on the
control lever side. Adjust the length as
needed.
d. Wrap the remaining strap around the oppo-
site side of the handle and hold it in place
with your hand.
WARNING: Serious operator injury could
occur if the operator has tied or
strapped the loose end of the
operator's belt strap to the machine. Always wrap the strap so
that you can let go and get away
quickly in case of bag fire or
explosion.
4. Turn the control switch to the "On" position.
CAUTION: To prevent damage to the floor,
make sure the machine is in
motion when the contact wheel
is engaged with the floor.
5. Feather-cut in by easing the contact wheel down
onto the surface with the control lever while the
sander is in motion.
Page 10 AMERICAN SANDERS TECHNOLOGY Apollo 8 Operator's Manual
6. When contact wheel is fully engaged with the
surface, gradually adjust your pace for adequate
finish removal. Keep sander in motion while the
contact wheel is engaged with the surface or
dwell marks will occur.
7. Move the machine in the direction of the grain in
the wood whenever it is possible. Sand the
surface at a constant pace.
8. Gradually feather-cut out at the termination point
by easing the contact wheel up with the control
lever.
9. Repeat technique described in steps 5, 6, 7, and
8 and sand back down pass just made. When
completed, begin a new pass by overlapping
previous pass half the width of the abrasive.
Stagger termination points to prevent a distinct
ridge and a better blend when edging.
10.Empty contents of the dust bag into a metal
container located outside the building. Dust bag
should be emptied whenever full, as indicated on
bag.
WARNING: Do not overfill dust bag or seri-
ous fire may result. Never leave
a dust bag containing dust unattended. Sanding dust can spontaneously ignite and cause a fire
or explosion. Use only genuine
American Sanders Technology
replacement bags.
Figure 9
CAUTION: An overfilled dust bag may ef-
fect machine balance and performance. Do not handle or
disturb dust bag and elbow while
sanding or damage to the floor
may occur.

Sanding Cuts and Sandpaper
Initial Cut
The purpose of the initial cut is to remove old finish
and gross imperfections on the floor surface. The
sanding equipment should be adjusted to heavy
sanding pressure setting and a coarse abrasive
belt should be used. If the surface is severely
damaged by deep scratches, preexisting dwell
marks, uneven planks, etc., it may be necessary
to sand across or diagonally to the grain to restore
evenness to the surface. If these conditions are
not present, the initial cut should be done in the
direction of the grain.
If glazing, loading, or burning takes place immediately into an initial cut, select a coarser abrasive.
If this should occur during an initial cut, the
abrasive has dulled and must be replaced.
Abrasive Belts
Note: All part numbers listed are for a carton of 10 belts
Final Cuts
The purpose of a finishing cut is to remove the
scratches produced during the initial cut. Use a
fine (60 - 80 grit) grain abrasive and a reduced
sanding pressure setting.
If the surface remains rough after a finishing cut, it
may be necessary to use an even finer grain of
abrasive (80 - 100 grit). Care should be taken in
selecting the grit size of the abrasive. A very fine
grain will close the pores on a wood floor making
admission of a stain difficult.
If glazing or burning should occur immediately into
a finishing cut, reduce the sanding pressure. If it
should occur during a finishing cut, the abrasive
has dulled and must be replaced.

Chatter Wave Prevention
American Sanders are designed and manufactured to the
most rigid tolerances. However, after a finishing cut it is
possible to see “chatter” or “waves”.
The best guarantee to remove the chatter is to finish the floor
with a rotating horizontal sander, such as American Sanders
Technology’s Sander 16.
To minimize chatter when using a belt or drum sander the
following steps should be taken:
DRUM MARKS...are caused by the operator lowering the
1.
drum to the floor without forward traverse. These marks
should be removed by
mark. Cutting at the mark while maintaining the same
path will only increase the mark depth and width.
See figure #10.
2. UNEVEN WALKING SPACE...can leave lengthy “waves”.
The machine cuts more material during the slower pace.
Pay particular attention to a steady, even pace.
3. EXCESSIVE LIGHT CUTS...may reveal high spots on the
paper/contact wheel and cause chatter. Take a heavier
cut and increase the pace.
cutting at a 45 degree angle to the
Figure 10
4. DEBRIS...lodged between the paper and the drum will
leave chatter. On a belt sander, debris may be adhered
to the drum. Insure the drum is clean and free of debris
before placing the paper on.
5. ABRASIVE QUALITY...may vary. Belt seams can be
thicker on low quality paper and cause chatter. Use only
American Sanders Technology specified sandpaper.
Store abrasive according to manufacturers recommendation.
PROPER CARE OF YOUR MACHINE CAN MINIMIZE
CHATTER AND WAVES.
1. V-BELTS...can cause vibration and chatter if they are of
low quality. Use only belts specified by American
Sanders Technology.
2. TRUCK AND CASTER WHEELS...with flat spots, out-of-
roundness, or debris adhered to their surface can cause
“waves” or a “chatter effect”. Always clean and inspect
all wheels before starting to sand, and before the finish
cut. Replace or true the wheels if found to be out-ofround. Never allow the sander to stand on hard
surfaces for lengthy periods of time.
3. DUST PICK-UP SHOES...may need adjusted differently
for different materials that are to be sanded. An improperly adjusted shoe will leave trailing debris that will be
run over by the wheels and cause “random waves”.
4. CONTACT WHEELS (DRUMS)...may be out-of-round and
cause “chatter”. Contact your American Sanders
Technology dealer for assistance to true or replace the
drum.
AMERICAN SANDERS TECHNOLOGY Apollo 8 Operator's Manual
5. BEARINGS...in the motor, drum, or fan system
may become worn and induce vibration which
could cause “chatter”.
6. PULLEYS...that are damaged or severly worn can
induce vibration and cause “chatter”. Contact your
American Sanders Technology dealer for assistance.
7. SANDPAPER TENSION...should always be
released when the machine is shut off for 10
minutes or longer to avoid compression of the
drum.
NOTE: American Sanders Technology is not
responsibile for rework of floors that are
unacceptable to the customer. It is your
responsibility to insure your equipment is in
proper operating order, and that you use the
right machine for the job.
