Before Turning On Transmitter
The following checks must be performed before
the transmitter is turned on. Be sure the Starter
Switch is in the OFF position.
WARNING! Sudden Movement Hazard. Verify
that the Starter Switch is in the OFF position
before performing the following inspections.
The Starter Switch must be in the OFF
position to prevent accidental starting of the
machine.
Perform the following inspections while the
transmitter power is off:
• Inspect the operation levers, operation switches,
and exterior to check that they are not covered
in oil or other dirt. Clean with a clean cloth.
• Check for foreign material, such as particles of
small stones or sand, caught in small openings
near the operation levers and/or switches.
WARNING! Sudden Movement Hazard. Do not
operate the machine if foreign material
prohibits movement of operation levers and
the accelerator lever. The operation levers and
the accelerator lever must be free to operate
for proper operation of the machine.
• Check for any damage to the transmitter case or
rubber covers of the operation levers and
operation switches.
WARNING! Electrical Shock Hazard. Do not
operate the transmitter if its case, the rubber
covers, operation levers, or operation
switches are damaged. Damage to these items
may cause internal component damage and/or
electrical failure.
• Check the movement of each operation lever
and operation switch for smooth operation and
free movement and return to the NEUTRAL
position when released. Repair any lever or
switch immediately before returning to
operation.
WARNING! Sudden Movement Hazard. Do not
operate the machine using the transmitter if
the levers do not return to the NEUTRAL
position freely. Levers must return to the
NEUTRAL position freely for proper operation
of the transmitter.
• 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.

Check that the power is turned on and the display
is functioning properly. There is a risk of incorrect
operation or serious accidents occurring if the
display is not displayed.
