Section 3 - Operation
Crushing Hazard - Personnel on ground
must stay clear of pothole protection
Do not drive elevated in areas where
electrical cords or debris are in the path
Maintenance of the Pothole
Protection Device
As with all safety devices, periodic inspection
and maintenance is required to ensure the
proper operation of the pothole protection
device. This mechanism is designed to reduce
ground clearance and assist in the stability of an
elevated aerial platform in the event the aerial
platform encounters a "drop-off" or "pothole."
The nature of this safety feature relies on
maintaining a consistent ground clearance,
therefore, if the aerial platform ever does come
to rest on the pothole device, the platform
should be immediately lowered and "locked
out" to prevent further use until a complete
inspection of the mechanism is performed by
a qualified technician.

1. Maintenance Support - The maintenance support
is a safety mechanism designed to support the
scissor assembly. When properly positioned it
can support the scissor assembly and empty
platform. The maintenance support must be used
when inspection and/or maintenance is to be
performed within the lifting mechanism. Refer to
Section 3.12 for procedure on how use and store
the maintenance support.
The maintenance support must be used
when inspection and/or maintenance or
repairs are to be performed within the
lifting mechanism. Failure to use this
safety mechanism could result in death
or serious injury.
Do not reach through the scissor
assembly when the platform is raised
without the maintenance support properly
positioned. Failure to avoid this hazard
could result in death or serious injury.
