Front wheel, 210x65, Air

Front wheel, 3.00"-4", Air

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.

VARNING

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.

The four-digit code indicates which protection circuit has been triggered.

Repair of defective units

Apart from specific OEM-approved spare parts (contact Permobil for further information on these), there are no replaceable parts in the Rnet control system. Consequently, defective units must be sent to

Permobil or a Permobil-approved repairer for repair.

NB

If any part is replaced without Permobil’s approval, the wheelchair’s warranty lapses. Permobil cannot be held responsible for losses of any kind arising as a result of a component of the Rnet control system being opened, adjusted or modified without permission.
