NOTE
Do not alter the primary conditions of regulation and do not
touch the sealed parts.
!
The engine is started and stopped by ope-
rating directly on the RGK420SA controller
Consult the controller manual for a complete
understanding of its performance.

STARTING
By start-up of the generator the welding circuit
is immediately operative, i.e. under voltage.
Make sure that there are no unwished electri-
cal contacts between the components of the
outside welding circuit (electrode, electrode
holder gun, workpiece, etc…).
Verify that plugs will be disconnected or that
the main switch will be off in order to assure
the engine start without any electric load on.
To switch on the controller when battery power
is present at the terminals, turn the key switch
STOPPING
For shutdown under normal conditions,
proceed as follows:
Break the welding process in course.
Break the production of a.c. auxiliary
generation dividing the loads or opening
the electrical protection interrupter.
Let the engine run with no load for a few
minutes.
Turn to minimum rpm: AUTOIDLE selector
(I8) to AUTOIDLE position or acceleration
control (16) to minimum position.
to the ON position. The device switches on and performs a
self-test. The model and revision number appear on the display.
With the controller switched on but before the motor is started,
the pressure/temperature/battery charging icons indicate the
state of the corresponding sensors.
To start the engine, press the START button for 1
second. The controller runs the engine start procedure but
makes only one start attempt. If the attempt fails, you must
repeat it, press START again.
Please note that machines with autoidle (where provided), when
the switch is placed on "autoidle", will remain at the minimum
number of revolutions if no load is taken. Drawing power will
automatically raise the number of engine revs to the nominal
value and likewise the tension in the alternator. Instead, by
setting the auto-idle signal to “max”, the engine revs will
immediately rise to the nominal value and likewise the tension
in the alternator.
For the machines with manual accelerator, it is necessary to
accelerate the motor manually inorder to reach the nominal
tension.
We advice to start the machine at the minimum rpm, moving
the acceleration control (16) to the minimum position or the
AUTOIDLE selector (I8) to AUTOIDLE position.
After the starting, keep the engine runs for a few minutes before
the energy withdrawal. Check the tab:
To stop the engine, turn the key switch back to the OFF position.
The controller performs an engine cooling cycle (if required) and
then runs the engine stop procedure. The controller switches
off at the end of the engine stop procedure.
The key can be removed in this position.
EMERGENCY SHUTDOWN
To stop the engine in a dangerous situation,
press the emergency stop button (L5).
To reset the knob, turn it clockwise.
REV.1-05/19
Start-up at low temperatures.
The engine has e good start-up to temperatures of -10°C. For
starting and use at lower temperatures, consult the engine use
and maintenance manual or contact our Technical Assistance
Service.
