3. OPERATION BY REMOTE CONTROL
• Never attempt to dismantle or modify the Transmitter and Receiver. Otherwise, an
electric shock or fire may be caused.
• Avoid dropping or hitting the Transmitter. A damaged part of the enclosure allows
water to enter inside that can cause trouble or failures and may result in a serious
hazard, such as a malfunction or electrical shock.
In the event of dropping and damage, contact us or our sales service agency for repair.
• Never wash the Transmitter and Receiver with water. That allows water to enter inside
and can cause trouble or failures and may result in a serious hazard, such as a
malfunction or electrical shock.
• Simultaneous remote control operation and manual operation of the crane are
allowed.
To ensure safety, all manual operations are disabled while the machine is operated by
the remote controller; however, the risk of serious accidents still exists due to
unexpected crane movements. The Crane must be operated by one method only.
• Before starting operation by using the remote controller, be sure to perform
inspections on the transmitter and the receiver in accordance with “INSPECTION AND
MAINTENANCE 9.1 PRE-OPERATION INSPECTION”.
3.1 CAUTIONS BEFORE OPERATION
1. To prevent the Transmitter from being accidentally
dropped, wear the waist belt (1) around your waist and
attach the Transmitter to the waist belt (1).
2. Be sure to perform inspections on the transmitter and
the receiver in accordance with “INSPECTION AND
MAINTENANCE 9.1 PRE-OPERATION INSPECTION”.
3. After powering on the transmitter, before operating the
crane, be sure to give an alarm sound (horn) to alert
people at the work site.
NOTES
• When the transmitter battery status bar has started illuminating in red, followed by an alarm
sound, immediately replace the battery with a fully charged battery.
• In the case of the remote control system, radio waves may not be received even at close
range due to jamming or depending on reflection conditions in the vicinity.
Operate as close to the Receiver antenna as possible.
• In crane operation, when the transmitter has not been operated for a certain period of time
after the last operation, it will be automatically turned “OFF”. To resume operating the
transmitter, press the start button on the transmitter twice to power “ON”.
