Safety instructions for service and maintenance tasks
WARNING
Exposed pinch points
Pinching, crushing of limbs (e.g. fingers) due to lack of caution in danger areas
While adjusting power seat functions, note that inherent pinch and shear points are located between the seat
frame and the power wheelchair frame.
Ensure that no body parts, such as hands or feet, are in the danger zone while you make adjustments to power
seat functions.
WARNING
Exposed pinch points when seat is folded up
Pinching, crushing of limbs (e.g. fingers), tipping over due to lack of caution when folding the seat up and down
To safely fold the seat up or down, grasp the seat by the seat frame, by the backrest or by the legrest adapter.
Never use the legrests themselves to fold the seat up or down as these do not provide a firm handhold.
After folding up the seat, shake it to verify that it is firmly locked. A seat which is not firmly locked could fall back
to its starting position and result in severe crushing injuries.
Always secure the wheelchair against tipping over with the active support of a helper when the seat is folded
up. Always fold down the seat before jacking the wheelchair up or down.
Move the seat to the lowest seat height before folding it up. If this is not possible (e.g. due to a defect in the
seat height adjustment actuator), then secure the seat during all work with the active support of a helper.
WARNING
Uncontrolled movement of components following loosening of plug and screw connections
Pinching, crushing and shearing of body parts
Ensure that body parts, such as hands and feet, are never in the danger zone.
Ensure that no interfering objects, such as clothing or other obstacles, are in the danger area.
Perform the work with the aid of a helper for support.
CAUTION
Failure to observe installation instructions
Pinching, crushing due to installation errors
Do not reach between force-actuated surfaces during installation work (e.g. when tightening screw connec-
tions).
CAUTION
Short circuit
Burns, injuries; damage to electrical/electronic components due to improper battery handling
Deactivate the main fuse before performing any work on the battery.
Only use insulated tools to perform maintenance work on the batteries.
Never connect the two poles of a battery with metal conductors or tools.
Ensure correct polarity when you connect the battery cables. Please refer to the battery circuit diagram on the
inside of the battery cover and on Page 156.
CAUTION
Re-use of self-locking nuts
Tipping over, falling of the user due to unintended loosening of the screw connections
Always replace self-locking nuts with new self-locking nuts after disassembly.
