Common faults and maintenance methods of wheelchairs

Fault 1: tire puncture

1. Inflate the tire.

2. Feel firm when pinching off the tire. If it feels soft and presses in, it may be a leak or a hole in the inner tube.

Note: When inflating, refer to the recommended tire pressure on the surface of the tire.

Fault 2: Rust

Visually inspect the surface of the wheelchair for brown rust spots, especially the wheels, handwheels, spokes and small wheels. Possible cause:

1. The wheelchair is placed in a damp place.

2. The wheelchair is not regularly maintained and cleaned.

Fault 3: Can't straight line

When the wheelchair slides freely, it does not slide in a straight line. Possible cause:

1. The wheels are loose and the tires are severely worn.

2. Wheel deformation.

3. Tire puncture or air leakage.

4. The wheel bearing is damaged or corroded.
