5. CUTOUTS
The unit is fitted with a series of cutouts which safeguard
it from incorrect use and faults that could damage it.
These are:
- Low oil pressure cutout
This turns the unit off when the pressure inside the
lubrication circuit is too low. When it triggers, the LED
(fig. 4 ref.1) lights up.
It is normally enough to top up the oil in order to start the
unit again.
WARNING
The low oil pressure cutout does not indicate the
level of the oil. The oil level must be checked regularly
to prevent damaging the motor.
- High water temperature cutout
This turns the unit off when the motor operating tempe-
rature is too high. When it triggers, the LED (fig. 4 ref.1)
lights up.
The unit must only be restarted after having determined
and eliminated the cause of the fault.
- Short-circuit and overload cutouts
To protect it against short-circuits and overloads, the unit
has been fitted with magnetothermal switches and
differential switches which interrupt power whenever
there is an alternator overload or a short-circuit.
Before returning power by turning the magnetothermal
switch to "ON" (fig.4 ref.8-9), eliminate the cause of the
problem.
For this purpose the following are used:
- a main magnetothermal differential switch which
interrupts power to all sockets in the event of a short-
circuit, overload and power earthing leakage.
- two magnetothermal switches to protect the low-power
sockets and interrupt power to the socket.

6. MAINTENANCE
WARNING
Any maintenance to the power unit must be done by
authorised personnel, with the motor off and after
leaving it to cool down.
6.1 Normal motor maintenance
Periodical maintenance operations to the motor are
indicated on the table. For more detailed information,
read the manual supplied by the motor manufacturer
which is attached to each power unit.
INFORMATION
Check the level of the oil by means of the dipstick
The oil level must always be between the MAX and
MIN indicated on the dipstick.
6.2 Motor oil change
The oil sump capacity YANMAR motor is
mod. 3TNE68G2A 3,4 L
mod. 3TNE74G2A 3,4 L
mod. 3TNE78G2A 4,8 L
mod. 4TNE84G2A 8,8 L
Topping and filling up is done through the inlet indicated
in fig.2 ref.1
For more detailed information, consult the motor use and
maintenance manual attached to the machine.
To replace the motor oil, remove the lower door of the
soundproof casing and the cap on the oil sump and let the
oil run out after placing a container under the frame. It is
advisable to run the oil out when this is still warm as it
flows better.
6.3 Deaeration of fuel system
The presence of air bubbles in the fuel system causes
irregular motor operation or prevents the motor reaching
the rated rpm. Air can get into the fuel system through a
badly sealed joint (pipes, filters, tank) or when the fuel in
the tank is at lowest level. To eliminate air bubbles inside
the fuel system, the cause of the infiltration must first of
all be removed before proceeding as follows:
1 - Loosen the bleed screws on the fuel filter and injection
pump (see motor use and maintenance manual).
2 - Manually operate the lever of the fuel pump (SC-suction
compression) until all the air inside the fuel system has
exited through the bleed screws.
3 - Tighten the bleed screws and start the motor.
4 - Repeat the above operations if the motor continues
to run irregularly.
