9.1.3 INSPECTION BEFORE STARTING ENGINE (RADIO CONTROL)
Check the following in this section before starting the work every day.
Omitting these inspections may cause serious bodily accidents.
See “OPERATION 2.1.2 CHECKING BEFORE STARTING ENGINE” to inspect the main
body of the machine also.
If there is any abnormality, be sure to fix it or contact us or our sales service agency.
[1] CHECKING PRIOR TO TURNING ON THE TRANSMITTER
When checking before turning ON the transmitter, ensure that the engine starter switch
is in the “OFF” position.
Otherwise, the engine may unexpectedly start during inspection of the transmitter and
cause serious bodily injury.
Perform the following inspections while the transmitter power is “OFF”:
• Check the control levers, operation switches and exterior for oily dirt or other contaminants.
Scrub away any dirt with a clean cloth.
• Also check for small particles such as stones, grit or sand that may have been caught in small
gaps near the control levers and/or operation switches.
If found, remove such particles completely. In the event where offending particles are caught in
the small openings near the control levers and/or operation switches, they may disturb correct
operations, causing unexpected movement of the Crane and resulting in a serious accident.
• Check for any cracks and/or damage to the transmitter enclosure, or impairment to the rubber
cover of the control levers and operation switches.
If cracks or damage is found, repair immediately.
Cracks or damage to the transmitter may allow water to enter inside, causing a malfunction and
creating a serious hazard.
• Make sure the control levers and operation switches all operate smoothly and properly, and
return to the original position (neutral position) automatically when you release your finger.
If the control levers or operation switches show any sign of a fault or malfunction, repair
immediately.
Failure to repair faults may cause unexpected movement of the Crane which result in a serious
hazard.
• Open the battery cover and check that the battery is installed in the correct direction.
If the battery is not installed correctly, install it again. If it is not installed correctly, internal
devices of the transmitter may malfunction, causing the Crane to perform unexpected
operation and resulting in a serious accident.
• Check if there is any foreign matter such as a metal or paper in the electrode of the battery.
If found, remove such particles completely. Otherwise, an electric shock or fire may be caused.
