Weather conditions may affect elas-
tomers. Invacare recommends that elas-
tomers be replaced once a year, other-
wise 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 se-
cures the elastomers to the suspension tube with a sili-
cone based lubricant.
