DANGER: 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.
DANGER: Sanding dust can self 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. Empty the contents
frequently. 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.
11
Operating Instructions
EN
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.
Preliminary cuts should be performed at angles
approximately 15° to the direction of the wood grain. Cut
direction should change on successive cuts with the final
cut performed in the direction of the wood grain. This will
minimize the tendency of waves to form and provide the
most even floor surface.
When sanding the area, work 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 rests 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. If the operating belt (American Sanders PN 53560A) is
used, proceed as follows:
a. Position the operating belt around waist.
b. Cross the straps at the waist.
(See Figure 13)
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 opposite side of
the handle, and hold it in place with your hand.

6. When drum is fully engaged with the surface, gradually adjust your pace for adequate finish removal. Keep sander in motion while the drum 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 drum up with the control lever. (See Figure 13)
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 to promote 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: 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. Activate the control switch.
CAUTION: To prevent damage to the floor, make sure the
machine is in motion when the drum is engaged
with the floor.
5. Feather-cut in by easing the drum down onto the surface with the control
lever while the sander is in motion.

Sanding Cuts & Sandpaper
Initial Cut
The purpose of the initial cut is to remove old nish and gross imperfections on the oor 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.
Final Cuts
The purpose of a nishing cut is to remove the scratches produced during the initial cut. Use a ne (60 - 80 grit) grain abrasive and a reduced
sanding pressure setting.
If the surface remains rough after a nishing cut, it may be necessary to use an even ner grain of abrasive (80 - 100 grit). Care should be taken in
selecting the grit size of the abrasive. A very ne grain will close the pores on a wood oor making admission of a stain difcult.
If glazing or burning should occur immediately into a nishing cut, reduce the sanding pressure. If it should occur during a nishing cut, the abrasive
has dulled and must be replaced.
WARNING: Do not overfill dust bag or serious fire may result. Never leave a dust bag containing dust unattended.
Sanding dust can self ignite and cause a fire or explosion. Use only genuine American Sanders replacement bags.
CAUTION: An overfilled dust bag may effect machine balance and performance. Do not handle or disturb dust bag and
elbow while sanding or damage to the floor may occur.

13
Chatter Wave Prevention
American Sanders belt machines are designed and manufactured to the most rigid
tolerances. However, after a nishing cut it is possible to see “chatter” or “waves”.
The best guarantee to remove the chatter is to nish the oor with a rotating
horizontal sander, such as the American Sanders Epoch HD.
To minimize chatter when using a belt or drum sander, the following steps should
be taken:
1. DRUM MARKS...are caused by the operator lowering the drum to the oor
without forward traverse. These marks should be removed by cutting at a 45
degree angle to the mark. Cutting at the mark while maintaining the same
path will only increase the mark depth and width.
(See gure 14)
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.
Figure 14
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 specied by American Sanders.
2. TRUCK AND CASTER WHEELS...with at 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 nish cut. Replace or true the wheels if found to be out-of-round.
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 dealer for assistance to true or
replace the drum.
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
specied sandpaper. Store abrasive according to manufacturer’s recommendation.

Figure 15
Figure 16
Figure 17
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 severely worn can induce vibration and cause “chatter”. Contact your American Sanders 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 is not responsible for rework of oors 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.
Sander Adjustment Procedures
DANGER: Electrocution could occur if maintenance and repairs are
performed on a unit that is not properly disconnected from
the power source. Disconnect the power supply before
attempting any maintenance or service.
DANGER: Moving parts of this machine can cause serious injury and/or
damage. Keep hands, feet and loose clothing away from all
moving parts of the sander.
The following information provides details on how to adjust different features/
controls of the sander.
Dust Shoe
To adjust the dust shoe follow this procedure:
1. Disconnect machine from power supply.
2. Loosen the three screws fastening the dust shoe to the chassis.
3. Adjust the dust shoe down to reduce clearance.
4. Adjust the dust shoe up to increase clearance.
5. Align the dust shoe to the chassis and tighten screws. (See Figure 15)
Sanding Pressure
There are three pressure settings to select from: heavy, medium and light. The
lower the position the heavier the setting. To change settings, raise the lever and
place in desired position. (See Figure 16)
Leveling the Drum
CAUTION: The belt tracking maybe adversely affected if machine is
operated unleveled.
The machine is leveled at the factory and no adjustments should be necessary.
After any maintenance is performed to the carriage system, the pointer on the
leveling bracket must be returned to original mark (See Figure 17).
If it is necessary to reset level after replacing wheels, follow this procedure:
1. Lower the drum to the floor.
EN

2. Drive the adjusting screw in, to sand heavier on the left (the drive belt
side). Back the adjusting screw out, to sand heavier on the right (the
side opposite the drive belts). Test the setting on an even surface.
Make further adjustments if necessary.
3. Mark new pointer location on main frame.
Belt Tracking
NOTE: The sanding belt should run evenly on the face of the drum. For
this, the outer edge of the sanding belt must be .09 inches (2mm) out from
the end of the drum. This provides optimum transition between “passes”.
WARNING: Injury to the operator could occur if any

3. Rotate the tracking adjuster screw counterclockwise to move the belt
in.
4. Rotate the tracking adjuster screw clockwise to move the belt out.
5. Test adjustment and tighten the locknut.
Operating Control
To increase the travel or extend the reach on the grip control, follow this
procedure:
1. Loosen the locknut on the control rod. (See Figure 19A)
2. Screw the control rod adjuster (See Figure 19B) “In” until the desired
reach is found.
3. Tighten the locknut.
To decrease the travel or reduce the reach on the grip control, follow this
procedure:

Routine Maintenance
Turn the adjustment screw “OUT” (See Figure 21) one quarter turn. Restore
tension using quick release lever and check adjustment. Repeat this process
if necessary. To lower tension, the adjustment screw is turned “IN”.
Bearings
Periodically check the bearings for wear or damage according to the
following schedule:
Guide rollers after 1st 650 hrs.
Idler pulley after 1st 1500 hrs.
Fan shaft after 1st 2500 hrs.
Tension roller after 1st 2500 hrs.
Arbor shaft after 1st 5000 hrs.
Motor shaft after 1st 5000 hrs.
Rollers
Periodically check the guide rollers and the tension roller for wear.

The following items need to be periodically inspected and maintained to keep your sander in good working condition.
Sanding Chamber
Periodically blow out the sanding chamber to prevent large accumulations of debris which could interfere with the performance of the tension roller.
NOTE: The tension lever should be in the run/tight abrasive position to blow out.
Wheels
Periodically remove the debris from the truck and caster wheels. Debris can cause waves on a sanded surface.
Dust Bag
Remove the dust bag from the machine and shake it thoroughly to remove the sanding dust from the dust bag. Turn the dust bag inside out and
machine wash in cold water to prevent pore blockage and loss of dust recovery.
Drive Belt
Drive belt tension is factory set and should not require adjustment. Periodically check the drive belt tension. Proper belt tension is achieved when
5 lbs. of force at the mid-span of the belt produces ½ inch of deection.
To increase belt tension, release tension using quick release lever (See Figure 6).
