Section 11-Wheels; Removing/Installing Rear Wheels; Quick-Release Axles - Invacare ProSPIN X4 Owner's Manual

SECTION 11—WHEELS
The seat height, seat depth, back angle, seating system, size/position of the rear
wheels, size/position of the front casters, as well as the user condition directly relate
to the stability of the wheelchair. Any change to one or any combination of the nine
may cause the wheelchair to decrease in stability. These adjustments MUST be
performed by a qualified technician.
Mounting rear wheels towards the front of the wheelchair will reduce the stability of
the wheelchair. Try various rear wheel positions to find the safest rear wheel
position appropriate for the users particular needs.
Anti-tippers, if equipped, MUST be repositioned before using the wheelchair.
Wheel locks MUST be adjusted before using the wheelchair.
After ANY adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely - otherwise injury or damage may occur.

Removing/Installing Rear Wheels

NOTE: For this procedure, refer to FIGURE 11.1 on page 68.

Quick-Release Axles

1. Push in the tip of the quick‐release axle and pull the axle (with wheel) out of the axle
bushing.
2. Push in the tip of the quick‐release axle again and pull the axle out of the rear wheel.
3. Repeat STEPS 1‐2 for the opposite rear wheel.
4. To reinstall the rear wheel onto the axle mounting plate, reverse STEPS 1‐3.
Make sure the detent pin and locking pins of the quick/quad-release axle are fully
released before operating the wheelchair.
The locking pins MUST be protruding past the inside of the rear wheel axle bushing
for a positive lock.
Keep locking pins clean.
5. If the locking pins are not protruding past the inside of the axle bushing or there is too
much movement of the rear wheel assembly in a back and forth position, refer to
Adjusting Quick‐Release Axles on page 68 or Adjusting Quad‐Release Handles on
page 69.
NOTE: During contact activities, Invacare recommends inserting quick‐release axles with the
head end to the inside of the wheelchair to prevent accidental release.
