10. HANDLING RADIO CONTROL
7.
Keep the engine starting switch on the transmitter
pressed for at least 2 seconds. The engine will start.
NOTICE
Do not run the starting motor continuously for more than
20 seconds.
If the engine does not start, wait for at least 2 minutes,
then try again.
REMARK
If the battery is low, the engine may not start even if the
starting motor turns. In this case, charge or replace the
battery.
8.
Turn the transmitter key switch to the START position.
(Hold for approx. 1 sec)
It becomes possible to operate the radio control and the
radio control operation display lamp (yellow rotating
lamp) lights up.
Between positions 1 and START, the switch is a momen-
tary switch, so it will return to position 1 when released.
If this operation is not carried out, it will be impossible to
remove the machine.
REMARK
It is possible to operate the horn and lights even before this operation.
9.
During radio control operation.
If any of the following conditions appear during radio con-
trol operation, follow the instructions.
Reception error: Move to a position where reception is possible.
REMARK
Depending on the jobsite, the antenna may be behind the work equipment. This will obstruct the radio
waves and cause poor reception.
If this happens, the yellow rotating lamp goes out and the red rotating lamp lights up.
Red emergency warning lamp lights up: Stop operations, check the appropriate location on the base machine
monitor, then carry out inspection and maintenance.
If this problem occurs, check the situation and turn the transmitter key switch OFF or press the emergency stop
switch to stop the engine completely before approaching the base machine.
(Do this because there is a serious danger of the machine moving unexpectedly.)
If there is a failure in the engine stop relay circuit or other related location, it may be impossible to stop the engine
with the radio control.
In this case, check carefully that the situation is safe, then mount the machine and turn the key switch OFF to stop
the engine.
