Permobil M1
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.
NOTICE
Risk of damage if tires are overfilled
Do not overfill the tires. Overfilling may result in damage to the wheel assembly.
NOTICE
Risk of reduced performance when tire pressure is
insufficient
Insufficient tire pressure may result in abnormal wear and a shorter driving
range.
CAUTION!
Maintenance by a qualified service technician
Only qualified service technicians should perform the maintenance and repair
specified in this manual. Read all instructions carefully before proceeding. If
any questions arise, contact Permobil for assistance.
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. Refit the plastic valve cap.
