● Ensure that there is no person or obstacle nearby (below or
above) when unloading.
●

Never leave the tipper body raised when not in use.
●


Always discharge the load with the top part of the rear body si
de
secured.
●

Observe the maximum payload on the weights plate on the

vehicle.
●

Check regularly that the suspension is in good condition and

that the tyres are inflated to the recommended pressures.
●

Distribute the load uniformly in the tipper body
.
●

T
ransport similar products that discharge easily.
SAFEtY A d VI c E
Discharge onto a flat and hard surface: a sloping
or loose surface may cause a change in the centre
of gravity, with an adverse affect on the stability of
the vehicle.
●

Never drive, even slowly
, with the tipper body raised.

For more information, refer to your registration certificate.
In each country, it is imperative that the towed loads authorised by
local legislation are complied with. To find out your vehicle's towing
capacities and its gross train weight, consult a franchised dealer.
The maximum authorised speed is reduced when towing (comply
with the legislation in force in your country).
With load transfer, the braked trailer weight can be increased,
on condition that the equivalent of this load is removed from the
vehicle so that the GTW is not exceeded. Warning: towing with a
lightly loaded towing vehicle may have an adverse effect on its road
holding.
The GTW and towed load values indicated are valid up to a
maximum altitude of 1000 metres; the towed load mentioned must
be reduced by 10 % for each additional 1000 metres.
High ambient temperatures may result in a reduction in the
performance of the vehicle in order to protect the engine; when the
ambient temperature is higher than 37 °C, limit the towed weight.
The kerb weight is equal to the weight without load + driver (75
kg) +
fuel tank filled to 90%. Before towing a trailer, check
that:
-

the nose weight on the

towbar ball does not exceed
the value (S) indicated on
the trailer's weights plate,
-

the maximum trailer weight

is less than the value
indicated on the trailer's
weights plate and the Gross
Vehicle Weight (GVW)
does not exceed the value
indicated on the vehicle's
weights plate.
-

in the case of a self-
supporting trailer

, the Gross
Train Weight must not
exceed the value indicated
on the vehicle's weights
plate.

these precautions are mandatory for any work on the hydraulic
system.
●

When carrying out maintenance work under the tipper body
,
place the tipper body in the safety position secured with its stay
(position indicated by a red arrow under the back of the tipper
body),
●

Never work under a tipper body that is not supported,
●

As a safety measure we strongly advise against doing anything
under the tipper body while it is being operated or while it is
being serviced.

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 servicing, the ball bearings are lubricated for life and
the plain bearings by the pumped fluid.
Lubrication
The tipper body and ram pivots do not have grease nipples.
Lubricate regularly the hinges and retainers for the tipper body sides
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 hose.
Touch-in the paint chips quickly to avoid the spread of rust.
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).
cleaning the valve slider
● Remove the plug 244A taking care to recover the ball.
●
Using a wide screwdriver
, remove the bore / piston bolt
assembly.
●

Check that the piston slides smoothly and remove any

impurities. Pass a magnet over if there is any swarf present.
●

Refit the assembly and ensure that the piston slides smoothly
.
Retain the ball with some grease on the plug for reassembly.
●

Bleed the hydraulic system.
Bleed the electro-hydraulic unit
● Remove the hexagonal plug 257.
●
Slacken by a half turn the bolt
587 located inside, using a
hexagonal 6 mm spanner.
●

Operate the electro-hydraulic unit for a few moments by

pressing the raise button.
●

The tipper body does not rise, or very slowly
. When fluid flows
from the orifice, the system is bled.
●

Retighten bolt
587 and refit the plug 257, check that the tipper
body lowers correctly.
