Cautions and warning statements

Safety information

• Safety information is indicated with the warning symbol. Wherever possible, safety information is provided in the relevant chapter.

Functionality

• After repairing, reprogramming or replacing parts, always check the functionality of the entire wheelchair. Pay special attention to safety features such as slowdown driving or drive inhibits when seat lift and tilt are both used.

Temperature

• Avoid physical contact with the wheelchair's motors at all times. Physical contact can cause burns. Motors are continuously in motion during use and can reach high temperatures. After use, the motors cool down slowly.

• If the wheelchair is not in use, make sure that it is not exposed to direct sunlight for lengthy periods of time. Some parts of wheelchair, such as the seat, the back and the armrest can become hot if they have been exposed to full sunlight for too long. This may cause burns or allergic reactions to the skin.

Programming

• Programming should only be conducted by healthcare professionals with in-depth knowledge of wheelchair control systems. Incorrect programming could result in an unsafe set-up of the wheelchair for a user. Handicare BV accepts no responsibility for losses of any kind if the programming of the control system is altered without authorization of Handicare BV.

Seat adjustment factory settings

Handicare BV will deliver a wheelchair with default factory settings. These settings depend on the options ordered with the wheelchair. When a configuration is ordered that causes interference, Handicare BV applies modified settings.

Moving parts

• Contact with moving parts of the wheelchair should be avoided. Contact with moving parts can result in serious physical injury or damage to the wheelchair. Pay attention to the following parts:

• Wheels (drive and castor)

• Electric tilt in space adjustment

• Electric high/low option

• Electric back adjustment

• Electric legrest
