General Power Tool Safety Warnings
Save all warnings and instructions for future use.
The term "power tool" in the warnings refers to your main-operated (corded) power tool or battery operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Clutter or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of ammable liquids, gases, or dust.
Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodied plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from
heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of cord suitable for outdoor
use reduces the risk of electric shock.

5
EN
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) or ground fault circuit
interrupter (GFCI ) protected supply. Use of a RCD or GFCI reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool
while you are tired or under the inuence of drugs, alcohol, or medication. A moment of inattention while operating
power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injury.
c) Prevent unintentional starting. Ensure switch is in off-position before connecting to power source and/or battery
pack, picking up, or carrying the tool. Carrying power tools with your nger on the switch or energizing power tools that
have the switch on invites accidents.
d) Remove any adjustment wrench or key before turning the power tool on. A wrench or key left attached to a rotating part
of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in
unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and
properly used. Use of dust collection can reduce dust related hazards. It is recommendation that the tool always be supplied
via a residual current device with a rated residual current of 30mA or less.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better
and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any
adjustments, changing accessories or storing power tools. Such preventative safety measures reduce the risk of starting
the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these
instructions to operate the power tools. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition
that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and
are easier to control.
g) Use the power tool, accessories and tool bits ect. in accordance with these instructions, taking into account the
working conditions and the work to be performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
5) Service
a) Have the power tool serviced by a qualied repair person using only identical replacement parts. This will ensure that
the safety of the power tool is maintained. If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualied persons in order to avoid a hazard.
Safety Warnings For Sanding Operations
1. This power tool is intended to function as a sander. Read all safety warnings, instructions and specications provided with
this power tool. Failure to follow all instructions listed below may result in electric shock, re, or personal injury.
2. Operations such as grinding, wire brushing, polishing or cutting-off, are not recommended to be performed with this power tool.
Operations for which the tool was not designed may create a hazard and cause personal injury.
3. Do not use accessories which are not specically designed and recommended by the tool manufacturer. Just because the
accessory can be attached to your power tool, it does not assure safe operation.
4. The rated speed of the accessory must be at least equal to the maximum speed marked on the power tool. Accessories
running faster than their rated speed can break and y apart.
5. The outside diameter and thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized
accessories cannot be adequately guard or controlled.
6. The arbor size of wheels, anges, backing pads or any other accessory must t the spindle of the power tool. Accessories
with arbor holes that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively and
may cause loss of control.
7. Do not use damaged accessory. Before each use inspect the accessory such as abrasive wheel for chips or cracks, backing
pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect
for damage or install an undamaged accessory. After inspecting or installing an accessory, position yourself or bystanders
away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged
accessories will normally break apart during this time.

EN
8. Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As
appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping ying debris generated by
various operations. The eye protection must be capable of stopping ying debris generated by various operations. The dust
mask or respirator must be capable of ltering particles generated by your operations. Prolonged exposure to high intensity
noise may cause hearing loss.
9. Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective
equipment. Fragments of work piece or a broken accessory mayy away and cause injury beyond immediate area of
operation.
10. Hold power tool by gripping insulated surfaces (handle) only, when performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power
tool "live" and shock the operator.
11. Position the cord clear of the spinning accessory. If you loose control, the cord may be cut or snagged and your arm or hand
may be pulled into the spinning accessory.
12. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grab the
surface and pull the power tool out of your control.
13. Do not run the power tool while carrying it at your side. Accidental contact with the spinning accessory could snag your
clothing, pulling the accessory into your body.
14. Regularly clean the power tools air vents. The motor's fan will draw the dust inside the housing and excessive accumulation
may cause electrical hazards.
15. Do not operate the power tool near ammable materials. Sparks could ignite these materials.
16. Do not use excessively oversized sanding disc paper. Follow manufacturer's recommendations when selecting sanding paper.
Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the
disc or kickback.
17. Risk of explosion. Floor sanding can result in an explosive mixture of ne dust and air. Use oor sanding machine only in a
well-ventilated area free from any ame or match.
Additional Rules For Safe Operation
1. Empty the dust bag or dust collection receiver frequently. Do not leave residue in dust bag or dust collection receiver
unattended. Always empty in a non-combustible metal container. Sanding wood or varnish produces dust that can self ignite
and cause injury or damage. Follow this precaution for storage.
2. Set all exposed nails. Sweep loose abrasive away from work area. Do not strike metal pipes, ect., with sanding paper.
Striking metal or abrasive particles with sanding paper produces sparks that could ignite the sanding dust which can cause
injury or damage.
3. Do not operate a partially assembled power tool. Keep all adjustments within manufacturer's specications. Keep all fasteners
tight. Operating a partially assembled power tool could result in injury to the operator or bystander and could cause damage to
the equipment or surroundings.
4. Do not attempt to change the sanding paper while the power tool is running. The sanding drum can snag clothing and cause
injury to limbs, and moving sanding paper can cause abrasions.
5. The power tool should only be used on an electrical system (mains) that is rated for the electrical requirements of the power
tool as shown on the nameplate. Use only on an earthing (grounded) system. Do not service the power tool if it is energized
or connected to an electrical circuit. Improper use could cause re or electric shock.

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.
CAUTION: Machine will pull itself forward. Make sure to have
firm control of the operator's handle when lowering the
drum to the floor.
CAUTION: Keep people out from in front of machine while in use.
Serious injury could occur.
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 in such 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 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. Figure 22

Operating Instructions
EN
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 gure 23)
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.
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 re or explosion.
4. Activate the control switch.
CAUTION: To prevent damage to the oor, make sure the
machine is in motion when the sanding drum is engaged with the oor.
5. Feather-cut in by easing the sanding drum down onto the surface
with the control lever while the sander is in motion.
6. When sanding drum is fully engaged with the surface, gradually
adjust your pace for adequate finish removal. Keep sander in motion
while the sanding drum is engaged with the surface or drum 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
sanding drum up with the feathering handle. (See figure 24)
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

Sanding Cuts & Sandpaper
Chatter Wave Prevention
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.
American Sanders oor sanders are designed and manufactured to the most rigid
tolerances. However, after a nishing cut it is possible to see “chatter” or “waves”.
For attest results, 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 35)
2. UNEVEN WALKING PACE...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 drum and cause
chatter. Take a heavier cut and increase the pace. Figure 35
PROPER CARE OF YOUR MACHINE CAN MINIMIZE CHATTER AND WAVES.
1. POLY 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 to be adjusted 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.
5. Bearings...in the motor, drum, or fan system may become worn and induce vibration which could cause “chatter”.
6. Upper roller...If worn or damaged, can cause chatter marks. Check upper roller before each job.
7. Worn or dull abrasive...Can cause chatter marks. Change abrasive belt regularly.
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.
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.
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.

Cómo evitar marcas de
vibraciones y ondulaciones
Las máquinas de Clarke Sanders están diseñadas y fabricadas con las
tolerancias más estrictas. Sin embargo, después de un corte de acabado, es
posible ver marcas de vibraciones y ondulaciones.
La forma más segura para eliminar las marcas de vibraciones es realizar el
acabado del piso con una lijadora giratoria horizontal, tal como la lijadora 16
de Clarke.
Para minimizar las marcas de vibraciones cuando se utiliza una lijadora de
correa o tambor, deberá seguir los siguientes pasos:
1. MARCAS DE TAMBOR...se producen cuando el operador baja el
tambor al piso sin desplazarse hacia delante. Estas marcas deben
eliminarse cortando en un ángulo de 45 grados respecto a la marca.
Cortar en el lugar de la marca mientras se mantiene el mismo recor-
rido solamente incrementará la profundidad y la anchura de la marca.
(Consulte la gura 14)
2. ESPACIO DE RECORRIDO IRREGULAR...puede dejar “ondulaciones”
prolongadas. La máquina corta más material durante el ritmo más
lento. Preste especial atención para mantener un ritmo constante y
uniforme.
3. CORTES LIGEROS EXCESIVOS...pueden revelar grandes manchas
en la rueda de papel/contacto y causar marcas de vibraciones. Tome
un corte más pesado e incremente el ritmo.
4. LOS RESIDUOS...alojados entre el papel y el tambor dejarán marcas
de vibraciones. En una lijadora de correa, los residuos pueden
adherirse al tambor. Asegúrese de que el tambor esté limpio y libre de
residuos antes de colocar el papel.
5. LA CALIDAD DEL ABRASIVO...puede variar. Las costuras de la
correa pueden ser más gruesas en papel de poca calidad y causar
marcas de vibraciones. Utilice únicamente papel de lija especicado
por Clarke. Almacene el abrasivo de acuerdo con las recomenda-
ciones del fabricante.
EL CUIDADO ADECUADO DE SU MÁQUINA PUEDE MINIMIZAR MARCAS
DE VIBRACIONES Y ONDULACIONES.
1. LAS CORREAS EN V...pueden causar marcas de vibraciones si son
de poca calidad. Utilice únicamente correas especicadas por Clarke.
2. LAS RUEDAS DE CAMIÓN Y ROLDANAS PIVOTANTES...con
partes planas, sin redondez o con residuos adheridos a su supercie
pueden causar efectos vibratorios o ondulatorios. Limpie e inspec-
cione siempre todas las ruedas antes de comenzar a lijar y antes del
corte de acabado. Reemplace o corrija las ruedas en caso de que
no presenten redondez. Nunca permita que la lijadora repose sobre
supercies duras durante períodos de tiempo prolongados.
3. LAS ZAPATAS DE RECOLECCIÓN DE POLVO...pueden necesitar un
ajuste especial de acuerdo con los diferentes materiales que se van a
lijar. Una zapata que no esté correctamente ajustada dejará residuos
en su camino sobre los que pasarán las ruedas, pudiendo provocar
“ondas aleatorias”.
4. LAS RUEDAS DE CONTACTO (TAMBORES)...pueden
no presentar redondez y causar marcas de vibraciones.
Póngase en contacto con su distribuidor de Clarke para
solicitar asistencia a la hora de corregir o cambiar el
tambor.
5. LOS COJINETES...en el motor, el tambor o el sistema
de ventilación pueden desgastarse y producir marcas de
vibraciones.
6. LAS POLEAS...que estén dañadas o desgastadas en
exceso pueden producir marcas de vibraciones. Póngase
en contacto con un distribuidor de Clarke para obtener
asistencia.
7. La TENSIÓN DEL PAPEL DE LIJA...debe liberarse siem-
pre cuando la máquina permanezca apagada durante
10 minutos o un período más prolongado para evitar la
compresión del tambor.
NOTA: Clarke no es responsable del trabajo de
reparación de los pisos que sean inaceptables al
cliente. Es su responsabilidad asegurarse de que su
equipo esté en buenas condiciones operativas y de
que usted utiliza la máquina adecuada para realizar
el trabajo.

Sander Adjustment Procedures
DANGER: Electrocution could occur if maintenance and
repairs are performed on a unit that is not properly dis
connected 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 chassis.
3. Adjust the dust shoe down to reduce clearance.
4. Adjust the dust shoe up the increase clearance.
5. Align the dust shoe to the chassis and tighten screws.
(See figure 36)
Laser Adjustment
1. Plug machine into power cord.
2. Remove protective cap from end of laser.
Note: Ensure the circuit breaker is in the ON position.
CAUTION: Laser Radiation- Do Not Stare into Beam.
Class 2 laser product.
3. Loosen the set screw on the side of the laser holder.
(See figure 37A)

Leveling the Drum
CAUTION: The belt tracking maybe adversely effected if
machine is operated unleveled.
The machine is leveled at the factory set 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 39).
If it is necessary to reset level after replacing wheels follow this
procedure:
1. Lower the drum to the floor.
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 machine
adjustments are made while the motor is running. Do not
attempt to make any adjustments while the machine is
plugged in or running.
To adjust the belt tracking follow this procedure:
1. Locate the belt tracking adjuster screw. (See figure 40A)
2. Hold the belt tracking adjuster screw and loosen the locknut.
(See figure 40B).
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.

Routine Maintenance
Bearings
Periodically check the bearings for wear or damage according to the
following schedule:
Guide rollers after 1st 200 hrs.
Idler pulley after 1st 200 hrs.
Rollers
Periodically check the guide rollers and the tension roller for wear.
EN
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.
Upper Roller
Remove the upper roller and blow dust and debris out of upper roller assembly regularly. If dust and debris get compacted in assembly, paper
tracking issues will occur.
Dust Bag
Remove the dust bag from the machine, unzip, empty and shake thoroughly to remove sanding dust from the bag. Turn the dust bag inside
out and hand wash in cold water and let air dry to prevent pore blockage and loss of dust recovery.
Drive Belt
To increase belt tension, open belt guard door and release tension using quick release lever. (See gure 8) Turn the adjustment screw “OUT”
(See gure 45) 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”.
Handle Height Adjustment
1. Remove power.
2. Lower the control lever.
3. Depress the button on the link rod. Twist outer tube to disengage.
(See gure 42)
4. Loosen the handle lever on the front of the handle tube. (See gure 43)
5. Pull the pin on the side of the handle tube and position operator
handle as desired. (See gure 44)
Note: The handle has 4 height positions. The pull pin should fall into
one of those positions.
