crossbar [C].
2. Close foot pedal and check ladder for secure
footing before using.
7.3 Adjustment and locking mechanism
with locking hooks
The ladder or a ladder element is locked on a lad-
der rung using the pair of locking hooks [E].
The anti-lift security device [E-1] on the locking
hock secures the ladder against unintentional
movement and serves as a transport lock.
1. Pull up on the anti-lift security device [E-1] on
the locking hook [E] and lift the ladder slightly
to unlock it.
The ladder elements can now be moved.
2. Before using the ladder, the locking hooks
must be correctly positioned on the ladder rung
and the anti-lift security device [E-1] must be
automatically engaged.
