1. Features of KX080-3 system

Basic electrical system structure is same as KX-3 and KX-3S series and some new values are added.
Newly added features of KX080-3 electrical system are as below.
o. Feature points

eli ery Required max. flow of service port varies according to the attach-
ments.
This new S/P flow control enables operators to select optimum flow
amount, thus regulate the attachment speed.
Fuel pump equipped as standard helps operator to supply fuel to
the tank.
Tank full-sensor is equipped to prevent fuel from overflowing.
Four min. timer relay gets the pump function continuously for 4
minutes.
Engine, V3800-DI, has the intake air heater which regulates the
intake air temperature for proper combustion and clean exhaust
gas.
The electrical control system consists of micro-computer unit to
work with.
(Note: Repeated ON-OFF only of the main key is prohibited, may
cause the heater coil damage.)
This system warns the people working around that the machine is
travelling nearby.
This is the safety oriented device.
Conventional machines are equipped with mechanical-link pedal-
control service port.
al e
This one is electrical control device which is easily remote selected
ON or OFF position at hand.
For operator's safety, the pressure switch detects the boom cylin-
sensing
der's internal pressure and alarms the operator.
