6.11 Wheel Lock and Wheel Lock Release
WARNING
Danger to life due to wheel lock malfunction. Incorrect wheel lock settings can lead to a loss of
brake functionality and therefore to serious bodily injuries and even death. Repairs and adjustments to
the wheel lock may only be carried out by authorised personnel.
WARNING
Risk of accidents and injury due to lack of brake functionality. When the wheel lock is deactivated
(push mode), no brake functionality is available. When moving the power wheelchair on an incline, the
person pushing must provide the appropriate brake force.
NOTICE
Risk of damage when parking the wheelchair with the wheel lock deactivated. Deactivating the
wheel lock may result in uncontrolled rolling of the power wheelchair. Therefore, ensure that the wheel
lock is engaged when parking the power wheelchair.
Both drive motors of the C2000 power wheelchair are braked simultaneously by the control unit
via a motor brake. In case of braking unit defects, the motor brake can only be replaced as a
unit with the drive motor.
In case of control unit failure or insufficient battery capacity, the power wheelchair can be pushed.
To do so, the wheel lock is unlocked with the mechanical wheel lock release. The wheel lock re-
lease is located on the opposite side of the fuse / charging receptacle on the side of the frame.
