10. Fill the tire with air, see below.
Filling with air
Check at regular intervals that the wheelchair's tires
have the prescribed tire pressure. An incorrect tire
pressure can cause deterioration in stability and
manueverability, plus extremely low air pressure can
give rise to abnormal wear as well as shorter driving
distances. So check regularly to see that the tires
are maintained at a pressure of 29 psi (200 kPa).
1. Unscrew the plastic cap on the air valve of
the tire.
2. Connect the compressed air nozzle to the air
valve and adjust the tire pressure to the
prescribed level.

WARNING
The recommended air pressure for front/rear tires is 29 psi
(200 kPa). Overfilling causes a risk of explosion. Incorrect tire
pressure can involve a deterioration of stability and
manueverability, so check regularly that the tire contains the
prescribed air pressure.
If the wheel bolt is removed for tire service, replace it with a
new, unused part from Permobil and tighten the bolt to the
recommended torque. Also, inspect the drive axle and wheel
rim for any damage. Damage to either part can cause the
wheel bolt to loosen or fracture. Permobil recommends that
wheel bolts be used only one time.
