Operation Precautions
Pre-Start Inspection
Before operation, perform the pre-start inspection
as specified for this machine. Serious injury or
death can occur if these inspections are neglected.
Any failure detected during inspection must be
corrected immediately.
Engine Starting
Ensure the area is clear of people and obstacles
before starting the engine.
Sound the horn as a warning before turning the
ignition key.
Before Turning On Transmitter
Check for dirt, cracks in the enclosure and
damaged display, control levers or operation
switches. WARNING! Unsafe Operation Hazard.
Do not use the transmitter if the enclosure is
cracked or the display, control levers or operation
buttons are damaged. The transmitter must be
clean and in good operating condition while
operating the machine.
Ensure that the transmitter’s control levers and
operation switches move smoothly and properly.
After Turning On Transmitter
Ensure the display of the transmitter displays the
correct indications.
Switch to each operation mode (CRANE and
OUTRIGGER), then check the display for the
proper indications when each lever and button is
manipulated. In addition, verify each applicable
load value on the transmitter is identical to that on
the moment limiter display.
After Starting Engine
Function Check OUTRIGGER Mode Using
Transmitter
• Switch the transmitter mode selector switch to
“OUTRIGGER.” Confirm that the display also
switches to the outrigger display.
• Operate the levers and check the outrigger
extend and stow operations.
• Operate the levers gradually. Abrupt movement
of the levers may cause the crane to overturn.
Ensure the position pins of the outriggers and
retainers are securely fixed.
Function Check CRANE Mode Using
Transmitter
Before switching operation mode to CRANE,
extend all the outriggers and ensure they are
securely positioned on the ground.
• Switch the transmitter mode selector switch to
“CRANE.” Confirm that the display also switches
to the crane display.
• Check to confirm that the Emergency Engine
Stop Switch (EMO) functions before starting.
The Emergency Engine Stop Switch (EMO)
shuts down the engine for the main unit and
shuts off power to the transmitter unit.
If you press the switch and the machine does
not stop, stop use immediately. Contact us or
our sales service agency.
Activate levers for crane operation and ensure
crane functions correctly.
See “RATED TOTAL LOAD CHARTS” on page
3-13 for proper loading of crane.
• Always operate the levers on the transmitter
slowly when hoisting a load.
• Do not perform multiple operations
simultaneously using the radio control, as only
one side may operate, which is extremely
dangerous.
• Never let go of the transmitter when the power is
turned on. Always power off the transmitter
before moving, carrying operations not using the
radio control, taking breaks, and when work is
complete.
• In emergencies or if even a minor problem
arises within the machine operating area, press
the Emergency Engine Stop Switch (EMO)
immediately to shut down the transmitter.
