MotorThis is the prime mover for operation by motor. In this machine, crane can be operated by

motor.

Motor coverThis is the cover to protect the motor.

ReceptacleThis is the receptacle for insertion of the cable like a cabtyre cord, etc. that transmit the

motive power.

Cabtyre cord OptionThis is the cord to connect the electric power supply that becomes the motive power with

the electric motor.

Motor control panelThis is the equipment to control the motor.

Starter switchThis is the switch to enable operation by motor.

Stop switchThis is the switch to disable operation by motor.

3-phase power supply lamp/ Control panel power supply lampThe lamps light up when the plug is inserted in the receptacle. If the lamps do not light up,

check to see whether or not the breaker is ON. If the lamps still do not light up, the controlpanel may be in trouble. If that is the case, please ask our company or its distributor for rem-edy.

Breaker

This the device to protect electric wiring and human body by shutting off electricity in caseof overcurrent or shortcircuit.

Emergency stop switch This switch is used when you want to stop the engine or motor urgently due to emergent situa-

tion when the engine or motor is in operation.

1. If you press the emergency stop switch during operation of the engine or the electric motor, the engine or the electricmotor is stopped and all the operations are stopped.

2. To reset the emergency stop status, turn the emergency stop switch clockwise while it is pressed.Then, the engine or the electric motor returns to the status ready for operation.

3. If the emergency stop switch is kept pressed with the plug being not inserted in the receptacle, the battery run-out will

be caused.

Travel operation by motor is impossible.

WARNING

Start the traveling operation after confirming the safety to see if there is anyone or anyobstacle around the machine or on the traveling road.Check particularly to see if there is any projection or groove in the course of reverse travel, and carry out ground levelingif necessary.

When starting the traveling operation, set the engine rotation to low speed and operate themachine slowly.This machine is designed in Earth-moving system that moves also the operator simultaneously with starting. Do notstart the traveling operation abruptly particularly in reverse travel. Otherwise, a serious accident may be caused.

If the safety can not be confirmed because of a blind corner in forward direction, stop travel-ing and confirm the safety.Take measures such as posting a guide, etc. according to the circumstances.

Do not travel the machine by motor.Travel the machine by engine. If you travel the machine by motor, the cabtyre cable entwines to cause falling down or unexpected accident.
