HINGE LEVERS
HINGE OPERATION
For safety, follow these push knob hinge instructions:
The ladder's inner section allows the ladder to
be folded into 4 set positions; extension ladder,
twin stepladder, leaning, and storage. Each of
these configurations is made possible by using
the hinge levers located under the ladder top.
To adjust the angle of the ladder:
1) With the center hinges in the closed
position (See Figure 1) pinch both levers
together and hold to unlock the hinge.
2) In the unlocked position (See Figure 2)
the ladder angle can be adjusted.
3) When the ladder reaches any of the 3 set
positions the hinge levers will automatically
spring back into the locked position.
4) To close ladder to the folded position repeat
steps 1-3.
Note: Excess pressure on the center hinge will
make the levers difficult to operate. Do Not Use
any tools to pry or manipulate the hinge and/or the
levers. If the levers are difficult to use simply move
one of the leg sections in or out to unbind the lock.
• Serious injury or death could result if supporting hinges
are NOT LOCKED when ladder is in use.
• Make certain supporting hinges are LOCKED before
using ladder EACH TIME.
