Emergency lowering via the operat-
ing panel
In certain circumstances, the truck control unit
prevents further lowering of the cab. (chain
breakage or slack chain situation, or faults
with chain monitoring, faulty height measuring
system, faulty rev sensor on the pump motor).
In these situations, the operator can select the
emergency lowering function
via the operat-
ing panel and the cab will lower to the ground
without further assistance.
– Do not actuate the foot switch.
– Push the operating lever for hydraulics (1)
forwards while touching the right-hand sen-
sor surface (3) (main lift lowering function).
– Wait six seconds. The enable button (2)
then flashes in red.
– Leave the main lift lowering function selec-
ted while pressing the enable button. The
main lift will slowly be lowered.

to shut down when the driver's cab is raised,
or if an operator in the raised cab becomes in-
capable of operating the industrial truck (e.g.
falls unconscious), the driver's cab can be
lowered by a second person on the ground us-
ing the hand-operated emergency lowering
valve.
