IS 9000 - 9500

3 USE OF THE GENERATOR

3.1 Preliminary checks

When first starting up the group, or after performing any
type of maintenance operation, it is good practice to
ensure:
- That the oil level is correct, using the dipstick provided

[fig. 3, ref. 1]. See the list of recommended oil types on
page 2.

- That all the group’s anchor points are properly locked.
- That all electronic users have been disconnected, to

avoid starting up the group under load.

- That the water and fuel lines are properly connected.
- That all electrical connections have been correctly

carried out, and that none of the connectors are in a
poor state of repair.

- That the water tap [fig. 4, ref. 2] is open.
- That the section of the water circuit leading from the

pump to the valve has been filled manually if there is
a non-return valve on the outboard water intake (as
recommended) [fig. 4, ref. 1].

3.2 Removing air from the system

The presence of air bubbles in the supply system is due
to incorrect operation of the motor or its inability to reach
the rated number of revs. Air can also penetrate into the
system through a joint that has not been properly sealed
(pipes, filters, tank) or when the fuel in the tank is at the
minimum level. To eliminate the air bubbles in the supply
circuit you must first of all remove the cause of the
infiltration and carry out the following operations:

1 - Loosen the bleeder screws on the fuel filter and on

the injection pump (see motor use and maintenance
manual).

2 - Manually adjust the AC fuel pump lever [fig. 5, ref. 3]

until all the air in the supply system has been expelled
through the bleeder screws.

3 - Tighten the bleeder screws again and start the motor.
4 - Repeat the above operations if the motor is still not

operating properly.

3.3 Start-up

Before starting the group, ensure that the preliminary
checks listed above under paragraph 3.1 have been
carried out.
Proceed to start up by pressing the “ON” button on the
control panel [fig. 2, ref. 4]. All the indicator lights will light
up in a self-test for approximately 5 seconds. After this
the panel on indicator [fig. 2, ref. 5] will remain lighted,
along with the “GLOW PLUG” indicator, signalling the
start of operations for pre-heating of the glow plugs,
which last about 10 seconds.

The group cannot be started during pre-heating of

the glow plugs

After this, start the group by pressing the “START”
button [fig. 2, ref. 3], which must be held down and only
released when the motor has started, taking care not to
hold the button down for more than 10 seconds at a time.
If the group is operating correctly this will be indicated by
light-up of the generator on indicator [fig. 2, ref. 6]. When
the above operations are performed, the group protec-
tion devices are automatically activated (see Chapter 4).

Repeated unsuccessful attempts to start the group
may cause an excessive build-up of water in the
drainage system, which may have a serious nega-
tive effect on the motor.
Should there be any difficulty in starting the motor
it is essential that the tap on the outboard water
intake be closed before making repeated and lengthy
attempts to start the motor.

3.4 Stopping the group

The group is stopped by pressing the “OFF” button on
the control panel [fig. 2, ref. 2].

Before stopping the generator group it is recom-
mended that you operate it for a few minutes without
taking off any power, so that the motor and the
alternator have time to cool down.

4 PROTECTION DEVICES

IS 9000 - 9500 is fitted with a series of protection devices
to safeguard against incorrect use or problems during
operation.
When the group stops because an alarm has been
triggered, details of the running hours will be displayed
on the control panel, along with a code indicating the
reason for stoppage of the generator group.
The following table contains a list of these codes and
their meanings:
