First change to the manual operation. Then, after the operation lever that
corresponds to the error number is manually returned to the neutral position,
change to the radio-control mode and check that the error number disappears.
When the mode indicator lamp displays the normal number and when the error
number does not reappear after operation is made, the operation can be
continued. If the operation lever cannot be moved or if the error number does
not disappear, then radio-control operation is impossible. Change to the manual
operation and then operate the crane.
“60”: Extension operation

70-89 The radio-control operation is impossible. Change to the manual operation and
then operate the crane.
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.

Measures for Emergency Case 22 Measures for Emergency Case
2. If the Radio-control is not Possible
1. The unloading solenoid of the radio-control
valve should be fastened so that the crane
can be manually stowed.
(1) Remove the cap nut.
(2) Loosen the lock nut and lightly tighten the
screw inside until it cannot be turned any
longer.
Fastening the screw too tight may cause
operation failures. Make sure to lightly
tighten the screw.
2. After manually stowing the crane, have the
crane and radio-control system
inspected/repaired at the nearest TADANO
distributor or dealer.
This is a measure to stow the crane in an emergency case. Do not
make any crane operation.

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 Appropriate measure
Distance between the transmitter and
reception unit is too far.
・ 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.
Operation is made near the noise-generating
source.
M00247
・ 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.
Operation is made in a place with an
intensive radio wave interference causing
noise to the radios and to television screens.
・ Approach the transmitter to the reception
unit and operate the transmitter.
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.
M22678
?
・ 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 25 Daily Inspection
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 transmitter or control
unit damaged? Do switches or rubber
parts of the transmitter have any 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.
