Adjusting The Wheelbase Length - Invacare Compass XE Owner's Operator And Maintenance Manual

SECTION 10—WHEELS

Adjusting the Wheelbase Length

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.
RECLINERS ONLY: Before using any recline position of this wheelchair, make sure
the rear wheels are in the most rearward position in the extended multi-position
axle plate to maintain the stability of the wheelchair. DO NOT change the
handling/maneuverability of the wheelchair by moving the rear wheels to any of the
forward positions. Moving the rear wheels to any of the forward positions will
change the center of gravity of the wheelchair, making the wheelchair less stable.
Wheel locks MUST be adjusted BEFORE using the wheelchair.
Anti-tippers, if equipped, MUST be repositioned BEFORE using the wheelchair.
NOTE: For this procedure, refer to FIGURE 10.8 on page 111.
Lengthening the Wheelbase will increase stability and maintain standard
maneuverability of the wheelchair.
Shortening the Wheelbase will increase maneuverability and distribute additional weight
onto the rear wheels.
Centering the Wheelbase gives you maneuverability and stability.
