4. Take the rim apart.
Assembly
Assemble in the reverse order.
Tighten the six screws using a dynamometric wrench.
Tightening torque: 22 Nm.
The recommended tire pressure for pneumatic tires is 200 kPa (2 bar). Overfilling entails a risk of explosion.
Incorrect tire pressure may result in lower stability and maneuverability. Check regularly that the tires have the correct pressure.

2. Slide the wheel onto the shaft using hand force
only. Ensure that the wheel bottoms on the
shaft.
3. Mount the washer (3) onto the bolt (2) and
secure the wheel. Use a torque wrench to
tighten the bolt to 17.7 ft-Ibs (24Nm).

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 36 psi (250 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.
The recommended air pressure for front/rear tires is 36 psi (250 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.
