Permobil C400 Corpus 3G Lowrider Repairs

Filling with air

Figure 16. Filling Valve on Pivot Wheel.

Check at regular intervals that the wheelchair’s tires have the prescribed tire pressure. An incorrect tire pressure can cause deterioration in stability and manoeuvrability, 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.

Figure 17. Filling Valve on Drive Wheel.

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 manoeuvrability, 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.
