Compatibility of fuels
Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only Diesel fuel additives authorised for use are those that meet the B715000
standard.

Fuel
The capacity of the tank is about 90 litres.
Fuel tanks of different capacities may be fitted,
60 and 120 litres, depending on the engine.
Low fuel level
When the low fuel tank level E (Empty) is
reached, this warning lamp comes on.
At this moment, you have approximately 10 or
12 litres left in the reserve, depending on the
capacity of your tank and the engine.
You must refuel as soon as possible to avoid
running out of fuel.
Refuelling
The fuel tank must be filled with the engine off.
► Open the fuel filler flap.
► Hold the black filler cap with one hand.
► With the other hand, insert the key and turn it
anti-clockwise.


► Remove the black filler cap and hang it on
the hook located on the inside of the filler flap.
A label inside the fuel filler flap indicates the type
of fuel to use.
Do not continue past the 3
rd cut-off of the nozzle.
This may cause malfunctions.
► After filling the fuel tank, lock the black filler
cap and close the filler flap.
With the Stop & Start system, never
refuel with the engine in STOP mode;
you must switch off the ignition using the key.
Fuel system cut off
In the event of an impact, a device automatically
cuts off the fuel supply to the engine and the
vehicle's power supply.
It triggers the hazard warning lamps and the
courtesy lamps, as well as the unlocking of the
doors.
After the impact and before restoring these power supplies, check that there
are no fuel leaks or sparks to avoid any risk of
fire.


► To restore the fuel supply, press the first
button, located on the front right-hand side.


► To then restore the power supply, press
the second button, located in the battery

Special features

– Never work under a tipper body that is not
supported,
– Switch off the power supply to the electro-
hydraulic unit using the circuit breaker,
– Vehicle stationary, engine off.
For safety reasons, we very strongly
advise against doing anything under the
tipper body while it is being operated or while
it is being serviced.
Maintenance
Reservoir
Regularly check and top up the engine oil level.
Change the oil once a year. If the oil contains
water, change it.
Regularly check the condition of the hose and
ensure the hydraulic system is properly sealed.
Pump and motor
No servicing required. The rolling elements are
permanently lubricated and the bearings are
lubricated by the pumped oil.
Lubrication
The pins of the tipper truck and the ram do not
contain lubricant. Regularly lubricate the hinges
and the grab handles of the side boards as well
as the retaining hooks of the rear board.
Sub-frame and tipper truck
For maximum service life, you are advised to
maintain your tipper truck by regularly washing it
using a power washer.
Carry out any required paint touch-ups quickly to
prevent the spread of rust.
After 8 months of use, check the tightening torque of the connection
between the chassis and the underbody (in
accordance with the manufacturer's
bodybuilding recommendations).
Cleaning the slide valve
► Loosen cap 244A, taking care with the ball
and retrieving it.
► Using a wide screwdriver, unscrew the banjo
bolt/piston assembly.
► Check that the piston slides freely and
remove any foreign bodies. Use a magnet to
remove any metal filings.
► Refit the assembly and make sure that the
piston slides freely. Retain the ball with a little
grease on the cap for refitting.
► Bleed the hydraulic unit.
Bleeding the hydraulic unit
► Unscrew hexagonal cap 257.
► Loosen internal screw 587 by half a turn,
using a 6 mm hex key.
► Operate the unit for a few seconds by
pressing the raise button.
The tipper truck does not rise or rises very
slowly. When the oil exits through this opening,
the unit is bled.
► Retighten screw 587 and replace cap 257.
Check that the tipper truck lowers correctly.
