07.1 CONTROL DEVICES MOUNTED ABOARD

Emergency stop push button (picture 1)
The power generator is equipped with an EMERGENCY
STOP device to stop immediately the generator in case of
danger. The device is actuated by pressing the red
pushbutton (4) located on the front of the generator. The
engine stops. To disengage the emergency stop device, ro-
tate the red pushbutton clockwise until it pops out.
The generator cannot be restarted if the
emergency stop device is activated.
Das, automatic engine shut off
Safety device mounted aboard. It shuts off the engine
automatically to avoid possible damage, in case of one of
the following irregularities: low oil pressure (No. 2 pic.1),
failure of the battery charger (No.3 pic.1).
The lighting of one of the indicator lamps on the control
panel points to the specific failure.
When the engine is off and the start key switch
is in the ON position, the low oil pressure and
battery charger failure lamps will be
illuminated.
This device does not exempt the user from
checking the engine oil level by using the
dipstick located on the left side of the unit.
This check must be made daily.
Arc force control
This device allows the welding generator to supply and
control automatically an additional welding current in a
condition of low voltage of the welding arc, without changing
the welding current value selected. Any electrode sticking
problem is so prevented.
07.2 EARTHING THE MACHINE (picture 2)
Before starting the generator, connect it to earth by using
the earth connection provided (4) and a cable of suitable
size without interposing switches or other devices capable
of breaking the electrical connection to earth. The earth
system must conform to CEI 64-8 regulations.
Do always connect the power generator to
earth. Check that the cables are in perfect
condition.

07.3 STARTING THE ENGINE

After checking and restoring if necessary the engine oil
level, and fuelling the unit, (if this is the first starting, it is
necessary to supply the unit of fuel), proceed as follows:
• Make sure that no load is connected to the unit.
• Turning the key switch (2) in "ON" position; (the lamps 3
and 4 will be lighted).
• Turning the key switch (2) in "ST" position.
If the engine does not start, turn the key
switch (2) to the OFF position (otherwise, the
automatic engine shut off - DAS, will prevent
starting the engine), wait about 10 seconds
and repeat the starting procedure.
• Let the unit run for about 10 minutes without connecting
any load, to allow the regular warm-up. The unit is running
at low rpm.
• Now it is possible to insert the load.
