Check and top up the fluid level regularly.
Replace the fluid annually. Replace the fluid if it
contains water.
Check the condition of the hydraulic hose and
the sealing of the hydraulic system regularly.
Pump and motor
Requires no ser vicing; the ball bearings are
lubricated for life and the pump bearings by the
pumped fluid.
Lubrication
The tipper body and ram pivots do not have
grease nipples. Lubricate the hinges and
retainers for the tipper body sides regularly,
as well as the catches for the rear tipper body
side.
Sub-chassis and tipper body
For maximum life, we recommend that you
clean your tipper body by washing it down
regularly with a hose.
Touch up paint chips quickly to avoid rust
spreading.After 8
months of use, check the
tightening torque of the fixings of the
underbody to the chassis (following the
recommendations of the body converter).

6The system is protected in such a
way that
it will only operate in your vehicle.
For safety reasons, the vehicle must
always be stationary for the driver to
perform operations that require close
attention.
When the engine is switched off and to
prevent discharging of the battery, the
system switches off after activation of
energy economy mode.
First steps
Use the buttons arranged below the touch
screen for access to the main menus, then
press the virtual buttons in the touch screen.
The screen is of the "resistive" type, it is
necessary to press firmly, particularly for
"flick" gestures (scrolling through a
list,
moving the map, etc.). A simple wipe will
not be enough. Pressing with more than
one finger is not recognised.
The screen can be used with gloves. This
technology allows use at all temperatures.
To clean the screen, use a
soft non-
abrasive cloth (e.g. spectacles cloth)
without any additional product.
Do not use sharp objects on the screen.
Do not touch the screen with wet hands.
In very hot conditions, the volume may be
limited to protect the system. This returns
to normal when the temperature in the
passenger compartment drops.
The system may also go into standby
(screen and sound completely off) for
a
minimum period of 5 minutes.

Digital Radio
Digital radio provides higher quality
reception and also the graphical display
of current information on the radio station
being listened to.
The different "multiplex/ensembles" offer
a
choice of radio stations in alphabetical
o r d e r.
Press repeatedly on " RADIO" to
display the "DAB Radio".
Select the " Navigate" tab.
Select a
list from the filters
proposed: " All", "Genres ",
" Ensembles " and then select
a


radio station.
Press the " Update" button to update
the list of "DAB Radio" stations
received.
DAB/FM tracking
"DAB" does not cover 100% of the
te r r i to r y.
When the digital radio signal is weak,
the " AF" (alternative frequencies) option
allows you to continue listening to the
same station, by automatically switching to
the corresponding "FM" analogue station
(if there is one).
When the system switches to analogue
radio, there is a
difference of a few
seconds with sometimes a
change in
volume.
When the digital signal is restored, the
system automatically changes back to
" DA B ".
If the "DAB" station being listened to is
not available, the sound will cut out while
the digital signal is too weak and the
alternative "AF" frequency will be greyed
out.

USB port
Insert a USB memory stick or connect
a peripheral device to the USB port in
the central storage space , provided for
transferring data to the system, using a
suitable
cable (not supplied).
To protect the system, do not use a
USB
hub.
The system builds playlists (in temporary
memory), an operation which can take from
a
few seconds to several minutes at the first
connection.
Reduce the number of non-music files and the
number of folders to reduce the waiting time.
The playlists are updated every time the
ignition is switched off or a
USB memory stick
is connected. The lists are stored: if they are
not modified, the subsequent loading time will
b e s h o r t e r.
