CAUTION!
Crushing hazard!
When extending or retracting the
ladder, you can catch or jam your
fingers if you proceed without
caution.
− Take care when extending or
retracting the ladder.
− When retracting the ladder
ensure that your fingers, hands
and arms are at the height of the
actuated unlock keys.
Locking device
With the aid of the locking devices
on the rungs
5
, the individual lad-
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
1
of a rung
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
1
of a rung is
visible
(see
fig.
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.
Extending the ladder
Extending the ladder by a few
rungs
If you do not extend the
ladder to its full length, the
blocks of the remaining
rungs that are not extended must
be located at the top end of the
ladder.
1. Set up the ladder on a solid and
level ground.
2. Stabilise the ladder by placing a
foot on the bottom rung
2
.
3. Extend the ladder from the bot-
tom up, rung by rung until the
desired length is reached (see
fig. D
).
With the aid of the locking
device, each section is automati-
cally locked as soon as the cor-
responding rung
5
has extended
to its maximum.
4. Make sure that each and every
ladder section is locked before
you climb onto the ladder (see
section “Locking device”).
