 Apply the handbrake.
 Make sure the lorry and trailer are in line and on a flat and stable surface.
 If the trailer is fitted with landing legs at the back these must be lowered. See § 8.6.
 If the trailer is fitted with a hinged rear under-run bar, this may be hinged. See § 8.4.
 Open the roof sheet. For the specific procedure for the opening of the specific type of roof sheet
see § 7.2, § 7.3 or § 7.4.
 Connect the hydraulic circuit of the lorry to the cylinder.
One hydraulic hose is connected with a single hydraulic circuit. A double hydraulic circuit has a
second hose (from the pressure relief valve) that is connected back to the hydraulic tank.

Make sure there is no one in the danger zone (X = length of the body).
Figure 2.3.2.b. – Danger zone when tipping
 Unlock the doors. For the specific procedure see the system description in § D.6. For use of the
grain hatch see §D.8.2.
 Tipping and lowering again takes place by operation in the lorry. See the hydraulic system manual
on the lorry for correct operation.
For information an example is given here of a control panel and operating
procedure for this type of PTO.
Figure 2.3.2.c. – PTO operating panel
 Start engine, check if there is sufficient air pressure.
 Press pedal and wait 4 seconds.
 Press blocking and switch PTO to “in”.
 Allow pedal to rise.
 Move tipping handle to “raise” and secure.
 Gradually raise body by changing the engine speed (number of revolutions never higher than 1500
rpm)
 Prevent the tipped material accumulating and moving against the tailboard by driving forward
EXTREMELY SLOWLY AND NEVER MORE THAN A METRE AT A TIME.
 When the tipping body has reached the required tipping angle release the lever and allow to return
to “hold”.
 Allow the tipping body to lower by GRADUALLY moving the tipping lever from “hold” to “lower".
With types without automatic PTO switching off the PTO must first be switched off.
 Control the lowering speed of th e body by moving the lever to “hold” to slow the body down or to
“lower” to increase the lowering speed.
 Bring the lever back to “hold” as soon as the tipping body is fully resting on the chassis.
 Disconnect the hydraulic connections.
 Lock the doors. For the specific procedure see the system description in § D.6.
 Close roof sheet. For the specific procedure for the closing of the specific type of roof sheet see
§ D.7.2, § D.7.3 or § D.7.4.
 If the trailer is fitted with landing legs at the back these must be raised. See § D.8.6.
 Before driving away check that the tipping has not caused any damage (e.g. to the signs, mud
flaps, mudguards, rear under-run bars, etc.).
When coupling and uncoupling the hydraulic connections, a small quantity of oil
may leak out of the coupling(s).
The use of antistatic oil-absorbing cloths is recommended.
These cloths are hydrophobe : they reject water and absorb only oil and liquids on
oil base (not supplied by STAS).
Additional documentation about these cloths – see for example www.seton.be
