WARNING! A Quantum Rehab Provider
should adjust the wheel lock with the
occupant in the wheelchair on the
maximum incline to ensure that the
wheel lock catches properly.
To adjust each scissor-style wheel lock:
1. Disengage the wheel lock. The front of the wheel
lock extrusion that faces the caster wheels should
be exactly 2.1 in. (5.3 cm) from where the wheel
lock blade makes contact with the plane of the
drive wheel. See figure 43. This applies to both
solid and pneumatic tires.
2. Loosen the hardware that fastens the wheel lock to
the frame. See figure 43.
3. Reposition the wheel lock so that the front of the
wheel lock extrusion that faces the caster wheels
is exactly 2.1 in. (5.3 cm) from where the wheel
lock blade makes contact with the plane of the
drive wheel. This applies to both solid and
pneumatic tires.
4. Tighten the hardware that fastens the wheel lock
to the frame.
5. Repeat the procedure for the other side.
Seat Tension
After a period of use, you may find it necessary to
adjust the seat tension.
To adjust the seat tension:
1. Loosen the screws that attach the seat to the side
rail on the left side (side with hook and loop
fastener). See figure 44.
2. Unfasten the hook and loop fastener.
3. Grab the bottom flap and pull the seat tight.
4. Fasten the hook and loop fastener.
5. Tighten the screws.
