• Always lower the platform to the travel position (boom
fully retracted and lowered) before moving the crane.
NOTE: Make sure that required restraining items, such as
railings, chains, cables, body belts with lanyards,
etc. are in place and are properly used. Never use
railings, planks, ladders, etc. on the platform for the
purpose of achieving additional reach or height.
See ASME B30.5 (Latest Edition) for additional
precautions and operating instructions for lifting
personnel using a crane.
Capacity Limitations
The combined weight of the platform and personnel shall
not exceed one-third the capacity of the operating radius
indicated on the capacity chart, located on the right side wall
of the operator’s cab. See Capacity Chart, page 4-1.
Turning Clearances
The front end of the boom extends beyond the end of the
frame. The operator must be aware of the maximum sweep
of the boom when turning and allow for adequate clearance
between boom and other objects.
Crane Shutdown
1. Park the crane on level ground.
2. Place the travel select lever in Neutral (N) and engage
the parking brake.
3. Lower any load to the ground and fully retract and lower
the boom.
4. Turn the ignition switch to the OFF position and remove
the key.
Battery Disconnect
The battery disconnect switch is located in the battery box at
the front of the crane. To disconnect the batteries, turn the
battery disconnect switch to OFF. Turn the switch to ON to
connect the batteries.
Unattended Crane
The configuration in which the crane should be left while
unattended shall be determined by a qualified, designated
individual familiar with the job site, configuration, conditions,
and limitations
Towing a Disabled Crane
If the crane becomes disabled and can not be moved under
engine power, the crane may be towed for a distance of
1.5 km (one mile) by another piece of equipment, which is
designed for towing. Always use a rigid tow bar and ensure
that the travel select lever and the transmission are in
Neutral (N). Restrict the travel to 25 kmph (15 mph).
If it is necessary to tow the crane for a distance in excess of
1.5 km (one mile), the drive shafts must be disconnected to
prevent damage to the transmission system.
CAUTION
To avoid damage to the parking brake and crane, do not
apply the parking brake while traveling.
Disengage the parking brake before driving. Damage to
the crane can occur.
WARNING
Tipping Hazard!
Changing weather conditions including but not limited to:
wind, ice accumulation, precipitation, flooding, lightning,
etc. should be considered when determining the location
and configuration of a crane when it is to be left
unattended.
Failure to comply with these instructions may cause death
or serious injury.
