7. CHECKING BEFORE OPERATION
Precautions shown in this section must be practiced prior to the day’s work, without fail.
Serious injury or death may arise when these checking are neglected.
Further, refer to the section of “OPERATION 2.1 Checking before Operation” for the checking of
the crane structure.
In the event where any failure is revealed in such checking, repair it, or contact us or our agents
for services.
7.1 CHECKING BEFORE STARTING ENGINE
7.1.1 CHECKING BEFORE TURNING ON THE TRANSMITTER
For the Checking before Turning ON the Transmitter, ensure that the engine starter key is in the
OFF position, as well as the Receiver main switch is OFF.
Otherwise, the engine may un-expectedly starts and cause serious injury or death, while
checking the Transmitter.
Perform the following inspections white the Transmitter power is OFF:
• Check the control levers, operation buttons, LCD screen, Accelerator lever and Grip for oily dirt or other
soil.
Scrub away the dirt with a clean cloth or such, when any.
• Check for foreign bodies such as particles of small stone or sand, caught into small openings in the
vicinity of the control levers and/or Accelerator lever.
Remove such particles completely, when any. In the event where such particles are caught in the small
openings in the vicinity of the control levers and/or acceleration lever, they may disturb correct operations
and cause un-expected motion of the Crane which results a serious accident.
• Check for any cracks and/or damage to the Transmitter enclosure, or impairment to the rubber cover of
the operation levers and control buttons.
Repair such cracks or damage immediately, when any.
Such cracks or damage may allow water to enter inside and brings troubles or failures to the Transmitter
and cause a serious hazard.
• Check the smooth and correct actions of each of the operation lever and control button, and the
Accelerator lever, as well as they smoothly return to the each neutral position when the finger is released.
Repair the operation levers, Accelerator lever and/or control button without delay, when any of them
show an incorrect action.
Any failure to the operation levers, Accelerator lever and/or control button brings troubles or failures and
cause a serious hazard.
• Check the connection cable for any cracks, damages and/or bents, or loose connection or damage in the
connector section.
Repair or replace to a new cable, where such cracks, damages, or loose connection is present.
