Lifting
Hydraulic blocking function
The hydraulic blocking function ensures that
all hydraulic functions are disabled whenever
the seat switch in the driver's seat is unloaded.
This is when the driver stands up from the
driver's seat or exits the truck. All hydraulic
functions are disabled in this case:
• Lifting the load
• Lowering the load
• Tilting the lift mast
• Auxiliary hydraulic functions
As soon as the driver sits down again, all
hydraulic functions are available again.
Emergency lowering of the load after the
hydraulics blocking function has been
triggered
If the truck's hydraulics are disabled by the
exhaust valve of the hydraulic blocking func-
tion, either permanently or due to a technical
fault, it is possible to lower a raised load with
emergency lowering at the valve block, see
⇒ Chapter "Emergency lowering", P. 4-288.
Lifting system operating devices
The method of operating the lifting system
depends on the operating devices included in
the truck's equipment.
Possible equipment variants include:
• Double mini-lever
• Triple mini-lever
• Quadruple mini-lever
• Joystick 4Plus
• Fingertip switch
– The following information must be observed
regardless of the equipment variant:
