WARNING
On the TR Series 3, the fork stem is permanently installed in the “Bullet” Caster Housing. Do not attempt to unscrew
the fork stem or the set screw. If it should become necessary to replace the fork stem on these chairs, this repair
can only be performed by TiLite at our factory.
If you ignore this Warning, you may fall, tip over or lose control of the

Note:
TiLite designs its rigid wheelchairs to be flexible for improved maneuverability and increased ride comfort.
However, this flexibility requires that your chair be set up properly. The following procedure will enable you to set up
your TiLite rigid wheelchair so it will perform to its potential.
1. Place the wheelchair on a smooth, level surface.
2. Make sure that all tires are properly inflated, that the camber tube is properly centered on the frame side to side,
that the camber tube is straight relative to the rear of the frame, that the toe-in/toe-out is correctly set up, and the
angle adjustable casters are square to level surface.
3. Loosen, but do not remove, the Allen screws in the camber tube clamps as shown in Figure 11-6.
Note:
Figure 11-6 depicts the camber tube clamps on the TR and YR Series 2. If you have a TR Series 3, locate
the corresponding Allen screws that secure the camber tube clamp to the frame and the camber tube to the
camber tube clamp.
