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 speci

fi

 ed 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 speci

fi

 ed by Clarke American Sand-

ers.

 2) 

TRUCK AND CASTER WHEELS

....with 

fl

 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 

fi

 nish 

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.
