4.2. Operation
When the running speed of the generating set has stabilised (approximately 3 minutes):
n
Check that the circuit breaker is connected.
o
Connect the plug(s) to the generating set socket(s).
4.3. Switching off
Warning
When the generating set is turned off, the engine continues to give off heat.
Appropriate ventilation should be provided after the generating set is turned off.
To stop the generating set urgently, place the engine switch on "
OFF".
n
Take the plugs out of the sockets and allow the engine to run without any charge for 1 to 2 minutes.
o
Place the engine switch (no. 2, Diag. D) on "
OFF"
and the set will stop.
p
Close the fuel tap (no. 1, Diag. D).
5. Safety features (if fitted, see specifications table)
5.1. Oil cut-out
This mechanism is designed to prevent any damage to the motor resulting from lack of oil in the motor sump. It automatically cuts out
the motor. If the motor stops and will not restart, check the motor oil level before looking for any other cause of the problem.
5.2. Circuit breaker
The electrical circuit of the set is protected by several magnetothermal, differential or thermal cut-out switches. Any overload and/or
short circuits cause the supply of electrical energy to be cut.
6. Maintenance schedule
6.1. Reminder of use
The maintenance interval frequency and the operations to be carried out are outlined in the maintenance programme.
However, it should be added that it is the environment in which the generating set is operating which determines this programme.
Accordingly, if the set is used in extreme conditions, shorter intervals between maintenance procedures should be adopted.
These maintenance schedules apply only to generating sets running on fuel and oil, that conform to the specifications given in this
booklet.

7. Maintenance procedures
7.1. Cleaning the air filter
Danger
Never use petrol or flammable solvents for cleaning the air filter element as this could result in a fire or
explosion.
n
Remove air filter cover (no. 1, diag H) by undoing screw (no. 2, diag H).
o
Remove pre-filter (no. 3, diag H) and then cartridge (no. 4,diag H)
p
Wash the pre-filter with a solution of domestic detergent and warm water. Leave to dry fully.
q
Gently tap the cartridge several times on a hard surface to remove any excess dirt. Never try to remove dirt using a brush. This
will just push the dirt into the fibres. Replace the paper element if it is too dirty.
r
Refit the air filter elements and cover (no. 1, diag H) in the reverse order of removal, and then tighten mounting bolt (no. 2, diag
H).
