GETTING TO KNOW YOUR LADDER
The Alta-One is made up of three major components: one inner ladder assembly and
two outer ladder assemblies that telescope over the inner. The inner and outer
assemblies work together with the Triple-Locking hinge and the lock tabs to adjust
the ladder into different lengths and positions, including an A-frame or stepladder, an
extension ladder, a staircase ladder, a 90-degree ladder and trestles for scaffolding.
Each rung has slip-resistant treads, and each leg is equipped with rubber feet for
improved traction.
Inner and Outer Assemblies. When the ladder is in its storage position, the inner
assembly remains inside the outer assembly. To raise the ladder’s height, simply
release the lock tabs and telescope the inner assembly upward and then
lock it in place at the desired height using the lock tabs on each side of
the ladder. To lower the height again, telescope the inner assembly
back into the outer.
Triple-Locking Hinge. The hinges are located at the
top of the ladder on each side when in the storage
position. The hinges unlock so you can adjust
the ladder into different working positions. To
Understand how the hinges work, follow the
instructions on back to adjust the ladder from
its storage position and into a working
position.
Work Platform (optional). The versatile
Work Platform fits on the rungs of any
Little Giant multi-use ladder and is rated
to hold up to 250 lbs. Use it as a tray for
a paint bucket or tools, or use it as a
sturdy, comfortable standing platform.
Now you can stand on your ladder for
extended periods without sore feet and
bruised shins, and you can work with
both hands in any direction. The Work
Platform also serves as a stabilizing
spreader bracket for your Little Giant
Alta-One’s trestle-and-plank scaffolding system.

GENERAL OPERATING SAFETY TIPS
Little Giant Classic Safety Tips
1. Little Giant Ladder Systems assumes no liability for damage or injury that may
result from failing to follow all instructions correctly.
2. The Alta-One has an ANSI duty rating of 250 pounds. For your safety, do not
exceed the weight limit. Follow other safety tips listed on your ladder.
3. Read all labels on the ladder before use.
4. Always hold the ladder with both hands on the vertical upper rails or hinges
while telescoping the inner ladder assembly up or down.
5. Make sure each of the four lock tabs is fully engaged into the rung holes before
climbing on the ladder. Failure to do so may result injury or death.
6. Fully engage each hinge lock before using. Failure to do so may result in injury
or death.
7. Do not open the lock tabs without securing the inner ladder assembly first to
prevent it from sliding down rapidly.
8. Use caution when using the ladder around electricity. Ensure that the ladder
does not come in contact with electrical currents.
9. Keep clothing and body parts out of working, mechanisms, including the hinges
and the lock tabs, to avoid pinching.
10. Do not stand above the third rung from top.
11. Keep all ladder rungs, ladder feet, work platforms, and other standing and
gripping surfaces clean and free from foreign materials.
12. Make certain the Work Platform is secure before standing on it.
13. Do not force the hinges in or out using any tools. You may cause permanent
damage to the hinge mechanism.
14. If there is pressure on the hinge lock pins, they may not open properly. Relieve
the pressure by moving one half of the ladder back and forth until the hinge
locks move with minimal force.
15. Use the proper angle for the extension ladder position. The distance from the
base of the ladder to the bottom of the support wall should be one quarter the
working height of the extension ladder, with a minimum of three horizontal feet.
16. Do not allow the full weight of the ladder to fall on the hinges as the ladder
folds from the extension to the A-frame position.
17. Make sure each of the four lock tabs is fully engaged into the appropriate rung
hole before climbing on the ladder.
18. For your safety, the rungs should always be level from front to back and from
side to side.
19. When using the extension position, always telescope the upper half of the
ladder first, and then extend the bottom if you need additional height (see
Figures 7 and 8).
20. Do not use outer or inner sections of the ladder as separate ladders
21. When the scaffolding plank is above the third rung from the bottom, it may be
used as a work area, but not as a standing platform.
22. The trestle-and-plank scaffolding system is rated to hold up to 250 lbs
General Ladder Safety Tips
23. Select the correct ladder for your job - a ladder that is both rated for your
weight and designed for the appropriate height and type of work you are
doing. For example, if you are cleaning out gutters, you may need a tall ladder
capable of safely supporting you at the required height, not a small stepladder.
24. Do a basic safety check before you get on a ladder. Look it over and make
sure that rivets and welds are tight and in good condition, that the rails are in
place, and that the ladder doesn’t wobble unsafely. Check the feet of the
ladder to make sure there’s no build up of dirt, oil, or other material that
would create an uneven surface.
25. Face forward and climb one rung at a time while going up or down a ladder.
26. Do Not stand on either the top cap or top two rungs of an A-frame stepladder.
27. Do Not stand on either of the top two rungs of an extension ladder.
28. If there are multiple ladders set up against a building, don’t step from one
ladder to the next. Climb down the ladder you’re on and back up the next.
29. When you’re on a ladder, don’t lean or reach far to one side; a good rule of
thumb is to always keep your belt buckle between the side rails. It’s safer to
come down from the ladder and move it closer to your work area than to
reach too far and cause the ladder to fall.
