In case of leaks
▶
Gas leaks are an EXPLOSION HAZARD so it is essential, as well as observing all legal regula-
tions and rules of competent authorities, to observe the following safety regulations.
●
Close the cylinder cocks and the cocks on the filling station risers and tanks.
●
Disengage the main switch of the electrical system of the plant or the refuelling area.
●
Block access to danger areas and move unauthorised persons away from the danger area.
●
Immediately notify the competent authorities and request restoration action.
●
Ventilate the surrounding area.
In the event of fire
●
Do not put out the emerging flame; Cool down the burning object if necessary.
●
Close the gas cylinder cocks and the cocks on the filling risers and tanks.
BURNING GAS = CONTROLLED GAS
●
If the flames spread to the surroundings, use the fire extinguishers as customary in order to put out the fire. Immediately evac-
uate any nearby vehicle from the danger area.
●
In case of fire, while continuing the fire fighting efforts, immediately inform the local FIRE BRIGADE.
●
Provide immediate aid to injured persons. First aid takes priority over the fire-fighting operations.

B.3 SYSTEM INTERVENTIONS
General warnings
Note Any change to vehicle layout absolutely requires repeating vehicle type approval.
Take into consideration the following warnings before performing interventions on the engine concerning or involving components
of the fuel supply system.
●
Before performing any work, you must shut off the cocks of the solenoid valves of each gas cylinder, after which the engine
must be started and let to run idle until it uses up the gas in the pipes and the engine cuts out. For the versions with an addi-
tional petrol tank, let the engine run until the "Recovery Mode" activates, i.e. until the engine moves over to petrol.
●
The parts must be cleaned with maximum care, while making sure that handling and assembly have not facilitated the entry of
sludge or foreign bodies. To this end, the protective caps of the components and sensors must be removed immediately prior
to placement.
●
Pay particular attention to the direction of installation of electrical connections.
●
All threaded connections must be tightened to the prescribed torque (see the Paragraph "Tightening torques (
➠
Page 7)").
▶
The components of the fuel system cannot be overhauled but have to be replaced when they are
inefficient. Washers, conical washers, self-locking nuts and gaskets contribute to the tightening
efficiency via a deformation and furthermore, are of a special type. They must therefore be re-
placed at every disassembly operation. After replacing them, the components must be system-
atically restored in the same points of origin and according to the original assembly sequence.
▶
After replacing the valves, or after any intervention on the high-pressure system, a HYDRAULIC
PRESSURE TEST (300 bar) must be carried out by IVECO CUSTOMER SERVICE, who will issue
a test certificate following a positive result.
