Locking device
With the aid of the locking devices
on the rungs , the individual lad-
6
der sections are locked when you
extend the ladder.
– Always check that all sections
are correctly locked before
climbing the ladder:
• The locking device of a section
is locked if the red section next
to both unlock keys
is not visible (see fig. B). If
you apply pressure to the corre-
sponding rung, it cannot be
pushed down.
• The locking device of a section
is not locked if the red section
next to one or both unlock keys
of a rung is visible (see fig.
1
C). If you apply pressure to the
corresponding rung, it can be
pushed down.
– Keep in mind that when you
extend the ladder from the top
down, the individual sections will
only lock when you have extended
the ladder to its full length.
Angle indicator
(See fig. A)
Make sure the ladder is at the cor-
rect angle (between 65°–75°)
before climbing the ladder.
The angle indicator
tional tool to determine the correct
angle and gives a good indication of
18
of a rung
1
is an addi-
8
whether the ladder is positioned at
the correct angle. Always check
whether the angle is actually cor-
rect and do not rely solely on the
angle indicator.
Operation angle indicator.
Set the ladder at the correct angle.
When the angle indicator
completely green, the ladder is at
the correct angle. If red is still visi-
ble at the top or bottom of the angle
indicator, the ladder is not at the
correct angle. Adjust the angle of
the ladder until the angle indicator
fully shows the green mark.
Maintenance angle indicator.
Periodically check the angle indica-
tor by slowly tilting the ladder back
and forth to see if the angle indica-
tor moves freely. Do not use the
angle indicator if it is damaged or
does not move freely.
Extending the ladder
Extending the ladder by a few
rungs
If you do not extend the
ladder to its full length,
the blocks
remaining rungs that are not
extended must be located at the top
end of the ladder with the protec-
tive caps .
