the tilt of the reclining surface can
also be adjusted for sizes 3+4.
4.13.6 Safety switch-off
The height and tilt adjustment supported
by a motor (see
Points 3.2 + 3.4
) is equipped
with a safety switch-off (
F
) that prevents "lif-
ting" of the sub-frame. If the footrests are in
contact with the ground, the downward or
upward movement is stopped or blocked.
The height and tilt adjustment rises auto-
matically 10 mm or swivels 10 mm back to
ensure the stability of
till.
. In any case,
till.
can always be raised to re-establish the stability.
Despite the safety switch-off, permanent presence of an accompanying person
is required when adjusting the motors !
4.13.7 Battery pack for motor support
Alternatively to the mains-powered power supply, the motors can also be
operated with a lithium-ion battery pack (
G
).
This battery pack has a low weight and a
high degree of power and safety. The battery
pack is charged automatically via the con-
trol element if it is connected via the mains
cable. The integrated LED (
H
) lights up in
yellow during the charging process. The LED
goes off when the battery pack is charged
completely. The buzzer installed in the con-
trol unit warns with an acoustic signal (beep
signal), if a button is pressed on the manual
controller and if the battery pack should be low. If the LED light flashes,
there has been a fault during the charging process. In this case, kindly con-
tact your specialist dealer (see
Point 8.5
).
Safety instructions:
• Do not open the battery pack housing, since the cells or circuits
probably develop excessive heat.
