In the event of a breakdown
Changing a fuse
The three fuseboxes are located on the
dashboard on the left-hand side, in the pillar
on the right-hand side and in the engine
compartment.
The designations provided are only for the fuses
that can be replaced by the user. For any other
work, visit a PEUGEOT dealer or a qualified
workshop.
Professional repairers: for full information
on the fuses and relays, consult the
wiring information and diagrams available
from a PEUGEOT dealer.
Removing and fitting a fuse
Good
Failed
Before changing a fuse, the cause of the fault
must be found and rectified. The numbers of the
fuses are indicated on the fuse box.
Always replace a faulty fuse with a fuse of
the same rating.
PEUGEOT accepts no responsibility for
the cost incurred in repairing your vehicle
or for rectifying malfunctions resulting from
the installation of accessories not supplied or
not recommended by PEUGEOT and not
installed in accordance with its
recommendations, in particular when the
combined power consumption of all of the
additional equipment connected exceeds 10
milliamperes.

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.
