Maintenance Support - Skyjack SJIII 3219 Operating Manual

Section 3 - Operation
WARNING
Crushing Hazard - Personnel on ground
must stay clear of pothole protection
device.
WARNING
Do not drive elevated in areas where
electrical cords or debris are in the path
of travel.
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.
