Emergency operation in the event of
malfunctions
In the event of a malfunction in the height
measurement system, the truck switches to
emergency operation.
In emergency operation, the assistance sys-
tems listed below that are dependent on the
lift height are not available:
●
Lift height display
●
Fork wear protection
●
Lift mast transition damping
Due to the lack of a measured value, the as-
sistance systems that are dependent on the
lift height will instead use calculated values for
the lift height.
For safety reasons, the calculated value is al-
ways below the actual lift height value.
The following assistance systems can contin-
ue to be operated, but with the restrictions of
emergency operation:
●
Intermediate lift cut-out
–
Release the lifting operating device so that
it can return to the zero position.
The fork carriage can then continue lifting at a
reduced speed.
●
Lift mast end-stop damping
–
Release the lifting operating device so that
it can return to the zero position.
WARNING
Risk of collision with the hall ceiling.
The fork carriage can now be lifted to the maximum
lift height without limitation.
–
Take note of the height of the ceiling.
●
Speed reduction when the fork carriage is
raised
The speed reduction activates at a lower lift
height than in normal operation.
