Depending on the failure conditions, changing to the manual operation may not
restore the normal operation.
Check the LED indications of the transmitter or the error number on the mode
indicator lamp of the control unit in order to take the correct measure for the erro
number.
Warning
The radio-control operation is electrically made with the radio-control system. Therefore, a
part or the whole of the radio-control operation becomes impossible when the radio-control
system has a problem.
If a problem of the radio-control operation is recognized, confirm the operation of the four
LEDs of the transmitter and the mode indicator lamp of the control unit.
(1) If the LED of the transmitter flashes
・If the power of the transmitter is turned on
while the motion selection switch is
operated, indications (2) as shown in the
table are displayed.
If the power of the transmitter is turned on
while the speed control lever is operated,
indications (4) as shown in the table are
displayed.
If the power of the transmitter is turned on
while the motion selection switch and
speed control lever are operated,
indications (1) as shown in the table are
displayed.
In either case, once again turn the power
on.
・If the power of the transmitter is turned on
while the push switch (the horn, engine
start and speed mode) is operated,
indications (3) as shown in the table are
displayed.
After confirming the switch, once again turn
the power on.
・If the motion selection switch is kept under
the operation state approximately for five
minutes due to a failure, trapped dirt or the
like, indications (2) as shown in the table
are displayed. After confirming the switch,
once again turn the power on.

The mode indicator lamp of the control unit
displays indications as are shown in the
figure to the right according to the
operational conditions.
If the mode indicator lamp displays the
indications not listed in the figure to the right,
the radio-control system has a problem.
Take an appropriate measure according to
the following table.
If more than two problems occur, each error number flashes in turn.
If the normal operation is not restored even after the measures in the following table are
taken, quickly stow the crane. Then, have the crane and radio-control system

13 After releasing your fingers from the switch of the transmitter and speed control
lever, turn on the power of the transmitter.
If the above does not restore the normal operation, the radio-control operation
is impossible. Change to the manual operation and operate the crane.
30-33 After the operation lever that corresponds to the error number is manually
returned to the neutral position, check if the error number disappears. When the
mode indicator lamp displays “L1” and when the error number does not
reappear after operation is started, the operation can be continued.
If the operation lever cannot be returned to the neutral position or if the error
number does not disappear, the radio-control operation of the part that has a
problem is not possible. Change to the manual operation and then operate the
crane.
Warning
It is dangerous to make other operations when the operation
lever of the part that has a problem cannot be returned to the neutral
position, since this would cause the part that has a problem to move
at the same time. Do not make such operations.

Troubleshooting Guide
M038010E
Radio wave transmission is hindered under the following conditions, which may stop the
crane operation. Take an appropriate measure according to the operational condition.
If the appropriate measure does not improve the situation, use the manual operation.
Operation example
Distance between the transmitter and
reception unit is too far.
Operation is made near the noise-generating
source.
M00247
Operation is made in a place with an
intensive radio wave interference causing
noise to the radios and to television screens.
A large metal cargo is lifted with the crane.
Or, there are obstacles between the
transmitter and reception unit such as wire
netting or metal doors.
Appropriate measure
・
Too large a distance between the
transmitter and reception unit may not
only hinder the radio wave transmission
but also increase noise influences.
Normally, make the operations within the
operating radius of the crane.
・When a noise generating device such as
a revolving light, electric fan or vehicle’s
air conditioner is used nearby, the
radio-control operation is influenced by
the source.
Turn off the noise-generating device
when it is possible to refrain from using it.
Since a motorcycle also generates a
noise, pay attention to motorcycles
passing through.
・Approach the transmitter to the reception
unit and operate the transmitter.
・Metal products between the transmitter
and reception unit hinder the radio wave
transmission. Move yourself to the
location where the reception unit can be
seen and then operate the transmitter.

Daily Inspection
Inspect the radio-control system at the time of the pre-operational inspection of the main
unit of the crane.
(1) Is the case of the transmi tt er or con t rol
unit damaged? Do switches or rubber
parts of the transmitt er have an y crack
or flaw?
Any damage on the case or any crack or
flaw on the rubber parts may allow water
or dust to enter inside, causing electronic
circuit problems or malfunction of the
crane.
(2) Do the motion selection switches and
speed control lever move smoothly?
Adhered dust or dirt may give unfavorable
impact on operations of the motion
selection switches or speed control lever,
causing operation failures or malfunctions
of the crane.
(3) Is the fixing screw of the transmitter’s
battery cover securely tightened?
A loose fixing screw of the transmitter’s
battery cover may allow water or dust to
enter inside, causing electronic circuit
problems or malfunction of the crane.
(4) Is the cable between the control unit
and communication unit loose or
damaged?
Is the antenna of the communication
unit damaged or loose?
If the connector of the cable or antenna is
loose, a radio wave reaching distance
may be reduced or the radio-control
system may be subject to noises.
In addition, if the cable or antenna is
damaged, the radio-control system may
be subject to noises.
