Insert the casters
into the ladder leg bushings, pressing the caster into the bushing
by hand until it is fully seated. Repeat this process for the
second End Frame Access Ladder.
2. Turn the End Frame Access Ladder over so that it rests
on its casters.
Holding an End Frame Access Ladder with one
hand, engage the “U” channel on one truss to the
ladder leg. Note: the locking pin on the truss should be disengaged
and free to be pushed back and forth. Depress the thumb plate
of the truss lock and align the pin to a predetermined hole
in the ladder leg. Release the thumb plate to engage the spring-loaded
Positive Engagement Lock.
3. Hold the second End Frame Access Ladder with one hand.
Repeat Step 2 to attach the other end of the truss to the second
End Frame Access Ladder.
4. Attach the second truss to the partially assembled scaffold.
Make sure both trusses are at the same height and parallel to
the floor. Do not screw the knurled thumb plate onto the threaded
nipple of the Positive Engagement Lock yet. The spring-loaded
pin, when properly positioned in the ladder leg holes, will
hold the truss in place.
5. Complete the assembly by laying the platform in place,
resting it securely within the platform ledges of each truss
No metal platform banding should be visible above the
vertical lip of the truss channel. Make sure the platform ledges
on the truss channel are thoroughly cleaned and free of debris
that would prevent the platform from seating properly into the
6. Adjust Platform Height
To adjust the platform height move to one end of the
scaffold and grasp both Positive Engagement Locks on the trusses.
Depress both thumb plates, pushing the pins out of the holes
in the ladder legs. The trusses are now free to move either
up or down on the ladder frame to the desired platform height.
Make sure pins are engaged.
Following height adjustment, release the thumb plates and allow
the spring-loaded pins to engage the nearest ladder leg hole.
7. Tighten the screws.
Screw the knurled thumbplate onto the threaded nipple
of the Positive Engagement Lock to positively prevent the pin
from backing out of the hole. Repeat Steps 6 - 7 at the opposite
end of the scaffold making sure the trusses are at the same
height and parallel to the floor. Check again to see that the
platform is properly secured within the truss channels.
