CHAPTER 11: CASTERS, FORKS AND CASTER PIN LOCKS
Adjusting the 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 casters to a larger or smaller size. Follow the procedures under “Replacing Casters” on page
11-1 to 11-2 (dependent on your TiLite model) to mount the casters in the alternative axle holes in the fork. The full range
of adjustability may not be available with 5”, 6” or 8” casters. Additional adjustability may be achieved with different forks or
casters or with fork stem extensions. Contact TiLite Customer Service for assistance.
Caster pin Locks
I
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 caster until either notch on the lock ring is directly beneath the T-Handle. See Figure 11-3.
2. Lift, rotate and lower the T-Handle into the engaged position on the caster pin lock. See Figure 11-3.
3. Make sure the pin lock is fully engaged in one of the notches in the lock ring.
To disengage the caster pin lock, lift, rotate and lower the T-Handle into the disengaged position on the caster pin lock. See
Figure 11-4.

Adjustable Angle Fork
Tools Needed:
• 7/16” Open End Wrench
• 5/32” Allen Wrench
1. Place the chair on a level surface.
2. Loosen the locknut while keeping the Allen screw from rotating.
Note
: It is only necessary to loosen (not remove) the locknut to allow the Allen screw to be easily turned with an Allen
wrench. See Figure 11-5.
3. Turn the Allen screw to adjust the angle of the fork.
4. Use a drafting triangle or similar 90º angle tool as shown in Figure 11-5, to adjust the fork to be perpendicular to the
level surface. To do this, first rotate the fork toward the rear wheel past the perpendicular position. Then slowly turn the
Allen screw to bring the fork forward to a perpendicular position.
5. Using the Allen wrench to prevent the Allen screw from turning (and the angle of the fork from changing), use the open
end wrench to securely tighten the locknut.
6. After tightening the locknut, recheck the fork to be certain it is still perpendicular to the ground before riding.
