2.1
Tyre pressure
The tyres must always be well inflated to ensure that the wheelchair brakes and rolls properly.
Use your fingers to remove the plastic cap which covers the inflation valve on the rim of the rear wheels.
Use a compressor or pump equipped with a pressure gauge to bring the pressure up to the correct level. Screw the plastic cap back on.
Check for correct tyre pressure on a weekly basis as indicated on the tyre (an intermediate value between min. and max. is recommended).
Proper tyre pressure makes the wheelchair considerably smoother and more controllable to manoeuvre.
Inadequate tyre pressure (especially if lower than prescribed) degrades the effectiveness of the parking brakes (the wheelchair may not remain stationary).
Do not exceed the pressure indicated on the tyre because you may damage the tyre and the inner tube.
Always respect what indicated on the tyre.
The front castors may also be of the "pneumatic" type; in this case, follow the same instructions.
Solid tyres do not require any inflation. This type of tyre requires less maintenance and reduces puncture repair or replacement costs. Compared to tubed or tubular tyres, they are not as smooth during
normal use and absorb less vibration when rolling on uneven ground.
2.2
Brakes
The parking brakes are a safety device and their efficiency must be checked daily.
The pressure brake acts directly on the tyre by means of a lever, which is why braking efficiency depends on correct tyre inflation pressure.
We recommend that you check your tyre pressure regularly to ensure that it is always correct.
The maximum safe gradient for the parking brakes to work properly is 3° (6%).
The parking brake is a safety device, and you must not use it while the wheelchair is moving as this could cause the wheelchair to overturn with possible injury to the occupant.
To check the effectiveness of the brakes, apply them as described below depending on the type of brake, and, with the person sitting in the wheelchair, try to gently push the wheelchair.
If the rear wheels do not turn or if they turn with great difficulty and still prevent unintentional movement of the wheelchair, the parking brakes are acting as required.
Check both brakes. Applying and releasing the parking brake may require more or less force depending on the type of brake chosen.
Occupants with reduced upper limb strength should use the extended lever.
Take care not to pinch/crush your fingers when applying and releasing the brakes, but also in any other situation where your hands come close to the brakes.
