wheelchairs).

Adjusting Front Seat Height
Note: Depending on the fork that came with your
chair, you may be able to adjust the front seat height
of your chair up or down without changing the front
casters to a larger or smaller size. Follow the
procedures under “Replacing Front Casters” on pages
76 or 77 (depending on your TiLite model) to mount
the front casters in the alternative axle holes in the
fork. The full range of adjustability will not be available
with 5” or 6” front casters. Additional adjustability may
be achieved with different forks or casters or with fork
stem extensions. Contact TiLite Customer Service at
1-800-545-2266 for assistance.
Caster Pin Locks
(TR Series, YG Series, YR Series, and Evo)
WARNING
ALWAYS be sure to disengage both caster pin locks
before attempting to propel your chair. If you ignore
this Warning, you may fall, tip over or lose control of
the wheelchair and seriously injure yourself or others
or damage the wheelchair.
To engage the caster pin lock:
1. Rotate the front caster until either notch on the lock
ring is directly beneath the pin lock. See Figure 109.
2. Rotate the L-Handle towards the front of the chair
until the pin lock snaps down into the locked
position.
To disengage the center pin lock:
Lift the L-Handle so the pin lock disengages from the
notch in the lock ring and rotate the L-Handle towards
rear of the chair.
