7.11 Power seat functions
7.11.1 Safety instructions
WARNING
Driving with power seat functions
Falling, tipping over due to driving with unallowable seat settings
► Only drive in road traffic and on inclines and downgrades with the seat tilt and seat height adjustments
lowered and with a vertical backrest. Always use a belt system.
► Slightly tilt the seat to the rear when driving down obstacles in a forward direction (e.g.curbs) and reduce the
speed.
► Drive with the seat raised or with the seat tilt/back angle adjustment activated only for short distances at
home. Always use the speed level 1 for this. Note that the field of vision is limited when driving. Always use a
belt system.
► Use the seat height adjustment and the seat tilt only on firm, level ground.
► To avoid uncontrolled driving movements, ensure that the control unit is always in "Power seat functions"
mode before using the power seat functions.
► To avoid hazardous situations, note the correct deflection direction of the joystick (see page79).
WARNING
Overloading
Risk of falling, tipping over due to non-compliance with technical data
► Note that the maximum permitted load of the power wheelchair may be reduced when using power seat func
tions (see the section "Technical data").
WARNING
Lack of maintenance
Severe user injuries, damage to the product due to maintenance errors
► Check the adjustment functions for visible signs of damage at least 1 x per month and ensure all screw con
nections are tight.
WARNING
Exposed pinch points
Pinching, crushing of limbs (e.g.fingers) due to lack of caution in danger areas, damage to the product
► Note that when seat functions are used, inherent pinch and shear points are located between the seat frame
and the power wheelchair frame.
► Ensure that no body parts, suchas hands or feet, are in the danger area while the seat functions are used.
► Ensure that no interfering objects, suchas clothing or other obstacles, are in the danger area while the seat
functions are used.
WARNING
Overloading of the actuators
Risk of falling, tipping, pinching, crushing of limbs due to improper handling
► Avoid overloading the actuators. Overloading may cause components to break, leading to uncontrolled drop
ping of the seat or causing the backrest to flip back.
NOTICE
Improper use of electric seat options
Damage to the product through user error
► When using electric seat options, note that the seat function actuators are not designed for continuous use,
only for short-term use under limited loads (10% load, 90% idle time).
► Observe the following guidelines: at maximum load capacity, 10 seconds of activation time must be followed
by approx. 90 seconds of idle time. The power seat functions are considered independently of the driving
function for this purpose.
► Only activate the power seat functions if no fault or error is present.
