How to Operate the Machine
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 manufac-turer’s
label on all chemicals used to determine
combustibility. Keep the work area well
ventilated.
DANGER: Sanding dust can spontaneously 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.
DANGER: Sanding dust can spontaneously 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

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 should be used. If the surface is severely damaged by deep
scratches, pre-existing 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 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.

Clarke American Sanders American 8 Floor Sander Operator's Manual
Chatter - Wave Prevention
Clarke 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 Clarke American Sanders’s Sander 16.
To minimize chatter when using a belt or drum sander the following steps should be taken:
1) DRUM PAPER...insure the paper is secured in the slot, but not too tight. Paper that
is too tight will force the drum slot wider, leaving a “slot mark chatter” on the floor.
2) DRUM MARKS........are caused by the operator lowering the drum to the floor 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.

Page 27
Chatter Wave Prevention (cont)
3) UNEVEN WALKING PACE..... can leave lengthy “waves”. The machine cuts more material during the slower pace.
Pay particular attention to a steady, even pace.
4) EXCESSIVE LIGHT CUTS.... may reveal high spots on the paper/contact wheel and cause chatter. Take a heavier cut
and increase the pace.
5) 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.
6) SANDER PAPER QUALITY....may vary. Belt seams can be thicker on low quality paper and cause chatter. Use only
Clarke American Sanders specified sandpaper.
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 Clarke American Sanders.
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-of-round.
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 Clarke 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) PULLEYS.....that are damaged or severly worn can induce vibration and cause “chatter”. Contact your Clarke American
Sanders dealer for assistance.
Clarke American Sanders 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.
