CONTROL UNIT–
SOLENOID VALVE
CLEANING
The following operations must be
carried out at authorised outfitting
centres by personnel with the
necessary knowledge of the tipper
and the appropriate equipment.
Periodically check the full efficiency of
the solenoid valve fig. 92 located on
the fitting at the bottom of the cylinder.
Clean the solenoid valve, following the
instructions given below:
Raise the unladen flatbed backwards
and engage the safety strut fig. 88 and
fig. 90
Lower the flabed by placing it on the
safety strut and release the pressure
of the hydraulic circuit by pressing and
holding down the lowering button for 5
sec fig. 86
Also use additional safety devices
such as a lifting bridge/crane crane for
securing the lifted flatbed on the strut
Undo the nut fixing the solenoid to
the solenoid valve coil
Remove the coil from the pin or stem
Prepare a container to be placed
underneath the solenoid valve to collect
the oil released from the cylinder
Undo the stem from its position
Clean the perforated section of the
stem with a jet of air
56
Fit the stem and tighten it to a torque
of 40 Nm
Refit the solenoid valve and
reconnect it electrically
Top up the oil previously collected
in the container by inserting it into the
tank of the control unit
Check the oil level on the tank after
topping up, with the body resting on
the safety strut

AFTER USE
49)
Keep the tipper well cleaned and
maintained. It will always give better
results.
IMPORTANT
47) All maintenance work requiring the
raised flatbed must be done with the
flatbed raised backwards, unladen and
with the safety strut engaged. In particular:
do not, for any reason, stand under the
raised flatbed without the strut applied /
operators must avoid leaning under the
flatbed while positioning the safety strut /
the safety strut must be inserted correctly
(see fig. 90), with the flatbed unloaded and
only during the rear tipping phase.
48) With the flatbed raised to the
maximum, approximately one litre of oil
should remain inside the tank.
49) If a long period of inactivity is
expected, it is necessary to lubricate the
various components subject to wear
and store the truck in a sheltered, dry
environment. In this way, when work
is resumed, the truck will be in perfect
operating condition.
