Replacing The Tyre And Air Chamber; Replacing The Castors And Bearings - Decathlon BW500 Modo De Empleo

Each week :
Check the tyre pressures. On the side of each wheel cover, you'll find the recommended tyre pressure.
●
A deflated tyre compromises the efficiency of the brakes and the fluidity of the wheelchair's
movements.
Check the efficiency of the quick removal devices [paragraph 6.3], clean them, and if necessary, oil the
●
axles and dowels with a li le grease to ensure that the wheels can be simply removed and replaced.
Each quarter:
Check for wear on the front wheels, which may alter the rear seat of the wheelchair if significantly
●
worn. In this case, proceed with replacing the wheels [par. 6.2].
Check the bearings on the front and rear wheels, and on the fork rota on. In this case, replace the
●
bearings [par. 6.2].
Grease the mobile parts, such as the quick removal axles of the wheels and the guides for the wheels.
●
We recommend using silicon oil as a grease, as it's effec ve and non-staining.
