Zra And Aero Z Fork Extensions; Floating Casters (Tr Series, Yr Series, Yg Series, Zr Series, Aero Z, Bb And Evo) - TiLite Rigid TR Series Owner's Manual

Note: If your chair is equipped with Frog Legs
square the receiver to the level surface because the flat
edge of the Frog Legs ® fork (see Figure 117 on page 82)
is not parallel to the receiver.

ZRA and Aero Z Fork Extensions

WARNING
Always use the same number of fork extensions on
both sides of 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.
Fork extensions are available for ZRA and Aero Z
wheelchairs (not ZR wheelchairs). See Figure 113.
Because extensions require a longer fork stem and
because the fork stems are permanently attached to the
receiver, it is necessary to replace both the receiver and
the fork stem if you wish to add extensions to raise the
front seat height.
Tools Needed:
• 5/32" Allen Wrench
1. Follow the procedure under "Replacing Front Forks"
on page 78 to remove the front casters and forks.
2. Completely remove the Allen Screw and locknut that
secure the receiver to the frame. See Figure 113.
3. Slide the receiver (and attached fork stem) out of the
frame and remove the caster mount dowel.
4. Insert the caster mount dowel into the new receiver
(and attached fork stem) and slide it into the frame.
5. Insert the Allen Screw through the frame, making
sure it slides through the notch in the receiver and
threads into the hole in the caster mount dowel.
6. Finger tighten the locknut.
7. Install the fork extension and fork onto the fork stem.
8. Reinstall the front caster. See "Replacing Front
Casters" on page 77.
9. Follow the procedures under "Angle Adjustable
Bearing Fork" on page 79 to square front caster.
Floating Casters
(TR Series, YR Series, YG Series, ZR Series, Aero Z,

Note: TiLite rigid wheelchairs are designed to be flexible
for improved maneuverability and increased ride
comfort. However, this flexibility requires that your chair
be set up properly. By following these instructions you
will be able to properly set up your TiLite rigid wheelchair
so it will perform to its greatest potential.
