Warning
The potential for an accident increases when oper-
ating an aerial platform that is damaged or malfunc-
tioning. Death or serious injury can result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.

Caution
The extension deck is free to move when the exten -
sion handle locks are disengaged. Personal injury
may result from accidentally extending or retracting
the deck. Make certain both extension handle locks
are fully engaged when the deck is extended in the
working position and when it is stowed. Do not at-
tempt to extend or retract the platform unless the
aerial platform is on a level surface.
To inspect the platform extension:
1. Inspect the extension handles and locks (refer to
Figure 7.14) on each side of the platform to ensure
they release to extend the platform.
Figure 7.14 – Platform Extension Handle
2. While facing the front of the platform, release the
platform extension handle locks. Grasp the handles,
raise them and push the extension deck forward to
the desired position. Fully lower the handles and
ensure the lock on each handle is engaged in the
slot on the platform guardrail (refer to Figure 7.14).
3. Inspect the rollers on the platform extension. They
must be in place, in good condition, and free to move
without obstruction.
4. Inspect the weldments for deformation and damage.
Try to move the rails back and forth to make sure the
platform extension deck fully locks in position.
5. Visually check the platform welds for cracks.
6. While facing the front of the platform, release the
platform extension handle locks. Grasp the handles,
raise them and pull the extension deck backward to
retract the deck. Fully lower the handles at the fully
retracted, stowed position. Ensure the lock on each
handle is engaged in the slot on the platform guardrail
(refer to Figure 7.14).
