CAUTION
Weather conditions may affect elastomers.
Invacare recommends that elastomers be re-
placed once a year, otherwise the perfor-
mance of the wheelchair may be affected.

fected if elastomers ARE NOT the same on BOTH
SIDES of the wheelchair.
NOTE: If elastomers squeak, lubricate the ends of
the elastomers with a silicone based lubricant.

WARNING
Ensure the detent ball protrudes past the fork BE-
FORE use. Otherwise, injury or damage may occur.
1. Remove the bolt and locknut securing the fork to
the fork stem.
2. Remove the EXISTING elastomer from the fork.
3. Position one end of the NEW elastomer into the
fork stem recess and the other end into the fork
recess (DETAIL “A”).
NOTE: Ensure the ends of the elastomer sit flush in
the fork and fork stem recesses.
4. Hold and squeeze the fork and fork stem together
(DETAIL “B”).
5. Insert the bolt through the mounting holes in the
fork to secure the elastomer to the fork.
NOTE: The bolt should be inserted from the OUT-
SIDE of the wheelchair, so the locknut will be on the
INSIDE of the wheelchair.
6. Install the locknut onto the bolt and securely
tighten.
