cracks.
3. Visually check all bolts and nuts fastening the platform
and guardrails in place. They must be present and
not show any signs of looseness.

the extension deck to the main platform deck.
Caution
The extension deck is free to move when the snapper
pins are removed, the latch handles are raised and the
locks are disengaged. Personal injury may result from
accidentally extending or retracting the deck. Make
certain both latch handles are fully lowered, the snap-
per pins are in place and the locks are fully engaged
when the deck is extended in the working position
and when it is stowed. Do not attempt to extend or
retract the platform unless the aerial platform is on a
level surface.

1. Inspect the snapper pins and latch handles (refer to
Figure 8.17) on each side of the platform to ensure
they release to extend the platform.

each of the latch handles and raise them to unlock the
extension deck. Push the extension deck forward to
the fully extended position. Fully lower the handles to
lock the platform in position and replace the snapper
pins (refer to Figure 8.17).
3. Inspect the rollers on the platform extension. They
must be in place, in good condition, and free to move
without obstruction.
