To prevent damage to the surface, make sure the machine is always moving when the contact wheel is in contact with the floor.
3. Work right to left. For each forward pass, move the machine 4” over the pass you have just finished. Retrace your reverse path without overlapping. See figure 6. 4. Feather-cut in by easing the contact wheel down onto the surface with the control lever while the sander is in motion. 5. 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. 6. Move the machine in the direction of the grain in the wood whenever it is possible. Sand the surface at a constant pace. 7. Gradually feather-cut out at the termination point (the end of your pass) by easing the contact wheel up with the control lever. Stagger the termination points for a better blend when edging. 8. Empty dust bag whenever it is 1/3 full. Never leave a dust bag unattended with sanding dust in it.

Clarke American Sanders American 8 Floor Sander Operator's Manual
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.

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.
