1. Place one foot on the bottom rung and
extend the ladder starting from the top.
à
Each rung should lock into place with
an audible "click".
2. Continue extending each section until the
ladder is fully extended.
3. When the last rung is fully extended:
à
Both rung release switches at the bot-
tom of the ladder must lock
à
The spring loaded stabilizer bar
should automatically extend to in-
crease the width of the base.
4. If any of the rungs are not locked, retract
the ladder completely and then re-ex-
tend. See section:
Retract the ladder
[} 6].
1.
Engage the unlock switches at the
base of the ladder to release all the
rungs.
2.
The ladder will retract when both locks
have been released. Air trapped in the
tube will help slow down the rate of re-
traction.
3.
When the ladder is completely retrac-
ted, secure it using the stowage strap.
See section:
Storage and Transport
[} 6].
4.
Retract the stabilizer bar.
To retract the stabilizer bar ends:
1. Fully retract the ladder and attach the
stowage strap.
2. Push both ends all the way in until they
lock into place.
