elastomers be replaced once a year, otherwise the performance of the
wheelchair may be affected.
NOTE: The performance of the wheelchair will be affected if elastomers ARE NOT the same on
BOTH SIDES of the wheelchair.
NOTE: If elastomers squeak, lubricate the ends of the elastomers and the shaft of the mounting
bolt that secures the elastomers to the suspension tube with a silicone based lubricant.
