To pre-select a
power unit
The preselection is the same for all power units except the telescoping
mechanism.
• Press the corresponding button once, e.g. button (1) for the main hoist.
The lamp in the button illuminates – preselection on.
With the telescoping mechanism, teleautomation with the target 0/0/0/0/0 is
always selected at the same time – fully retract.
The extension function is disabled in emergency mode.
Operating
a power unit
All the safety instructions contained in the sections on the individual power
units also apply to operation with the hand-held control.
• Press the required function buttons one after the other, e.g. for Lift main
hoist
, press button (1) first, and then also button (2).
The further you press button (2), the quicker the movement. The maximum
speed is limited to about 50% for all power units.
The table shows all the button combinations. Engaged buttons are shown
in black.

Danger of overturning when moving into the shutdown ranges
Avoid lowering the boom. If you cannot avoid lowering, try to set down the
load beforehand and ensure that the maximum permissible working radius
is not exceeded for the rigging mode as specified in the
Lifting capacity table.
Before slewing, always check whether this is permissible in the current
rigging mode;
à Notes on slewing in emergency operation, p. 14 - 46.
G
Risk of accidents when operating the slewing gear
Set down in the crane cab to operate the slewing gear. This prevents you
being pushed off the carrier or being crushed by the carrier as a result of
slewing.
Lay the connecting cable of the hand-held control so that it will not catch on
anything.
