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 Ameri- can 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.
