01 Opening / extending and deploying the ladder
1.1 Before using the ladder it shall be checked that all locking mechanisms are working properly.
If the mechanism is not working properly, do not use the ladder.
1.2 Stand and support the closed / retracted product vertically and upon a firm / level surface and
then place one foot centrally upon the fixed bottom rung (rung 1) to stabilise the ladder (see
figure 3).
1.3 Note that the ladder must be opened / extended from the lowest extendable section and not
from either a middle or the top section.
1.4 Using both hands, lightly grasp the stile tubes below the blue support rings of rung 3 (the
rung of the first / lowest extendable ladder section) and then pull up and fully extend the
section (see figure 3).
1.5 Repeat step 1.4 and extend each further ladder section (one at a time) until the desired
ladder length is reached (note that it will eventually become necessary to lower the extended
ladder to enable higher ladder sections to be extended).
1.6 Check all ladder lock indicators (immediately below each extended section) are showing 'full
green' (see figure 2).
1.7 Note the slope of the stabiliser bar feet and the location of the safety grip wall bumper square
pads and then correctly deploy and support the extended ladder forwards and at an angle of
75 degrees to the horizontal (see figures 4 and 5).
1.8 Ensure that the deployed ladder is secure by placing the stabiliser bar feet upon a firm and
level surface and both safety grip wall bumper pads against a firm vertical surface (e.g. a
wall). Whenever possible, secure / tie the top of the extended ladder.
02 Closing / retracting the ladder
2.1 Stand and support the open / extended product upright by firmly grasping one of the stile
tubes part way up the ladder with one hand and then using your other hand, fully depress
and then release both ladder lock release buttons (see figure 6) to unlock the lowest
extended ladder section (note that the ladder sections will not descend / self-close when
these buttons are depressed).
2.2 Using both hands, lightly grasp the stile tubes of the ladder and carefully / slowly pull down
all ladder sections (note that the lowest extended section will sequentially fully retract / close
first which will then automatically unlock the next extended section).
2.3 Whenever partly reducing the length of the extended ladder, always follow steps 2.1 and 2.2
first to fully retract / close the ladder and then follow steps 1.1 to 1.6 to re-extend the ladder
to the desired reduced length.
