SAFETY INFORMATION
Special Operating Conditions and
Equipment
Never operate the crane during an electrical thunderstorm.
Working in the vicinity of radio frequency transmission
towers and other transmission sources may cause a crane to
become "electrically charged."
When operating cranes equipped with electromagnets you
must take additional precautions. Permit no one to touch the
magnet or load. Alert personnel by sounding a warning
signal when moving a load. Do not allow the cover of the
electromagnet power supply to be open during operation or
at any time the electrical system is activated. Shut down the
crane completely and open the magnet controls switch prior
to connecting or disconnecting magnet leads. Use only a
non-conductive device when positioning a load. Lower the
magnet to the stowing area and shut off power before
leaving the operator's cab.
Crushing Hazards
Death or serious injury could result from being crushed by
moving machinery.
C l e a r a l l p e r s o n n e l f r o m t h e c o u n t e r w e i g h t a n d
superstructure area before removing the counterweight or
rotating the superstructure.
Barricade the entire area where the crane is working and
keep all unnecessary personnel out of the work area.
Never allow anyone to stand or work on or near the
superstructure while the crane is in operation. Always
barricade the tail-swing of the rotating superstructure.
Before actuating swing or any other crane function, sound
the horn and verify that all personnel are clear of rotating and
moving parts.
Watch the path of the boom and load when swinging. Avoid
lowering or swinging the boom and load into ground
personnel, equipment, or other objects.
Always be aware of your working environment during
operation of the crane. Avoid contacting any part of the crane
with external objects.

You must always be aware of everything around the crane
while lifting or traveling. If you are unable to clearly see in the
direction of motion, you must post a look out or signal person
before moving the crane or making a lift. Sound the horn to
warn personnel.
Clear all personnel from the outrigger area before extending
or retracting the outriggers.
Carefully follow the procedures in this handbook when
extending or retracting the outriggers. Death or serious injury
could result from improper crane set up on outriggers.
Be sure the outriggers are properly extended, set and the
crane is level for operation on outriggers.
All four outrigger beams must be equally extended to the mid
position vertical stripe or fully extended position before
beginning operation.
All four outrigger beam lock pins must be engaged before
operating from the mid-extend position.
The operator must select the proper Load Chart and LMI
program for the outrigger position selected.
Only the crane operator shall occupy the crane when
traveling or in operation.
Death or serious injury could result from being crushed by
revolving tires.
