9 Chatter Wave Prevention American Sanders Technology 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: 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. AMERICAN SANDERS TECHNOLOGY American 8 Floor Sander Operator's Manual Page 27

10 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 American Sanders Technology 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 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-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 American Sanders Technology 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 American Sanders Technology dealer for assistance. 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.
