Weights and towed loads
(kg)
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 kerb weight is equal to the weight without
load + driver (75
kg) + fuel tank filled to 90%.
Hydraulic system
These precautions are mandator y for any
work on the hydraulic system. Before towing a trailer, check that:
-
t
he nose weight on the towbar ball does
not exceed the value (S) indicated on the
trailer's weight plate,
-
t
he maximum trailer weight is less than
the value indicated on the trailer's weight
plate and the Gross Vehicle Weight (GV W)
does not exceed the value indicated on the
vehicle's weight plate.
-
i
n the case of a self-supporting trailer,
the Gross Train Weight (GTW) must not
exceed the value indicated on the vehicle's
weight plate.

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).
