4.2.5.4 Assembling the drive wheel rim
Read all warnings contained in this section before filling the tires.
Failure to do so may result in injury to the user and damage to the
wheelchair and other property and also void any warranty applicable
to the wheelchair.
1. Fit the two rim halves together with tire and if pneumatic tire is
used, it's inner tube. Tighten the six screws using a torque wrench.
Tightening torque: 16 lb·ft.
2. On wheels with pneumatic tires, fill the tire to recommended tire
pressure, 29–36 psi.
3. Fit the wheel on to the wheelchair. See
4.2.5.2 Mounting the drive wheels , Page 53.
4.2.5.5 Inflating tires
Read all warnings contained in this section before filling the tires.
Failure to do so may result in injury to the user and damage to the
wheelchair and other property and also void any warranty applicable
to the wheelchair.
Applies only if the wheelchair is fitted with pneumatic tires.
At regular intervals, check that the wheelchair's tires have the prescribed
pressure between 29–36 psi. Incorrect tire pressure can impair stability
and maneuverability, while extremely low tire pressure can cause
abnormal wear as well as shorter tire life.
1. Unscrew and remove the plastic valve cap on the tire air valve.
2. Connect the compressed air nozzle to the valve and adjust the tire
pressure to the prescribed level.
3. Install the plastic valve cap.
CAUTION!
Risk of injury if tire pressure is incorrect
Before operating the wheelchair for the first time and regularly thereafter,
check that the tire pressure meets the specifications in this manual. Check the
tire pressure when the wheelchair experiences a significant change in
temperature or altitude. Incorrect tire pressure may cause the wheelchair to
be less stable, less maneuverable and cause damage to the wheelchair and/
or bodily injury.
