INSTALLING QUICK-RELEASE
CASTERS (FIGURE 6)
WARNING
Pull on quick-release casters each time
BEFORE using the wheelchair to make sure
they are securely locked onto the wheel-
chair frame.
There are several configurations of the
quick-release caster. If caster fork stem
DOES NOT look like DETAIL "A" in FIGURE 6
when installed, DO NOT USE. Contact Ac-
count Services, 1-(800)-333-6900.
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 wheelchair can be stored and transported conveniently.
When using 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 ad-
justable 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 caster
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.
