curely locked onto the wheelchair frame.

lease caster. If caster fork stem DOES NOT look like

A Note About Quick-release Casters
Quick-release casters are an option that allow for quick and
easy removal of the casters from the wheelchair so the wheel-
chair can be stored and transported conveniently. When us-
ing the quick-release caster option, a spring loaded caster
head tube cap will be used instead of a stem nut to secure the
front caster to the chair frame. Unlike the stem nut, the caster
head tube cap is not adjustable and thus caster flutter will be
more evident with the quick-release caster option than it would
be with the standard caster attaching hardware.
1. Remove the bolt and locknut that secure the front
caster and the two (2) spacers to the fork.
2. Remove the dust cover on the top of the headtube.
3. While holding the fork and using a socket wrench,
remove the locknut that secures the fork, and spacer
in the headtube of the wheelchair.
NOTE: The dust cover and locknut are not used with the
quick release casters. Keep them for future use.
4. Remove the existing fork and install the quick release
caster fork through the headtube of the wheelchair
making sure the fork stem is approximately 1/4-inch
above the caster headtube.
WARNING
Make sure the detent pin of the quick-release
caster headtube cap is fully released BEFORE op-
erating the wheelchair.
5. Depress the detent pin of the quick-release caster
headtube cap and install over the top of the quick-
release caster fork stem.
6. Release the detent pin of the quick-release caster
headtube cap and pull on the fork to make sure the
fork is securely attached to the wheelchair.
7. Reinstall the two (2) spacers and caster onto the quick-
release caster fork.
8. Repeat this procedure for the opposite side.
