ATTENTION
1 . By start-up of the generator the welding circuit is
immediately operative, i.e. under voltage. Make
sure that there are no unwished electrical
contacts between the components of the outside
welding circuit (electrode, electrode holder gun,
workpiece, etc…).
2. Check that at the start-up the a.c. auxiliary
generation sockets do not feed any load.
Open the electric protection interrupter
of the generator or disconnect the plugs
of the loads from the sockets.
3. START-UP
Starting is actuated using the key which is an integral
part of the EP7 post on the front panel.
A) - Turn the key in a clockwise direction until all the
LED lights are illuminated.
B) - Wait until the “OIL PRESSURE” and “BATTERY
VOLTAGE” LEDs remain illuminated. If the ti-
mer lamp is used, the yellow “PREHEAT” LED
comes on for the set time of the imposed
settings.
C) - As soon as the green “ENGINE RUNNING”
LED starts to flash, actuate the key switch in a
clockwise direction (momentarily in the position
then with return to rest) until obtaining starting
of the engine.
If the motor does not start within 15 seconds, the
non starting alert will intervene: the two LEDs
“Engine running” and “glow plug” will flash
alternately (see motor protection description).
D) - At any time it is possible to stop the engine by
turning the key in an anti-clockwise direction
(OFF position).
In case of engine anomaly due to low oil
pressure, high temperature, broken
transmission belt, low fuel level or emergency
the EP7 will automatically stop the engine.

4. the motor starts up at its operating speed, 1500
or 1800 rpm. After start-up, allow the motor to run
for a few minutes before powering on the utilities.
See table;
5. start-up at low temperatures.
The motor will normally start up without problems
down to temperatures of -10° C, -15° C. In case
of starting difficulty, it is possible to repeat the
starting preheating for a max. time of 10 second,
.lightly turning the trimmer situated at the back of
the EP7 in a clockwise direction (see page
M39.13 relating to engine protection “trimmer/
glow plug”). For start-up and use at lower
temperatures please see the engine manual or
turn to our Technical Assistance Center.
In case of unsuccessful start-up, do not
insist for longer than 5 seconds. Wait 10 -
15 seconds before attempting another start-
up.
