Locking device
With the aid of the locking devices
on the rungs
6
, 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
8
of the
remaining rungs that are not
extended must be located at the top
end of the ladder with the protec-
tive caps
7
.
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 bottom
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
6
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”).
Extending the ladder to its total
length
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 top
down, rung by rung until the total
length is reached
(see
fig. E
and
F
).
Keep in mind that the locking
devices of the ladder only lock
when you have extended the lad-
der to its total length.
4. Make sure that each and every
ladder section is locked before
you climb onto the ladder (see
section “Locking device”).
