6. OPERATION
WARNING:
prior to starting the machine, read the “GENERAL WARNINGS” chapter.
After establishing and ensuring the stability of the machine, it may be used.
Steps for start-up:
- start the tractor;
- fill the suction cone with water or sewage using the dedicated inlet (2 fig. 3). Use the
vacuum pump for quicker priming. See the "OPTIONAL EQUIPMENT" chapter.
- activate the tractor power take off;
- increase the tractor revolutions until the pump starts (the priming time varies based on
the depth of the tank and the density of the suctioned material);
- bring the tractor back to the required number of revolutions.
Steps to stop:
- deactivate the tractor power take off by progressively decreasing the speed of the PTO;
- stop the tractor motor;
- disconnect the cardan shaft from both the tractor and the pump;
- remove the suction pipe from the cone to discharge the residual material contained
therein;
- open the valve inside the cone (using a suitable lever), to discharge any residual sewage
from the pump;
For all electric motor versions, after checking the correct direction of rotation, connect to
the power supply.
WARNING: before opening the delivery pipe, ensure that the system is not still un-
der pressure.
WARNING: never run the pump under no-load operating conditions, without filling
the cone (1 fig. 3) using the dedicated filling inlet (2 fig. 3).
If the vertical gap between the surface of the liquid and the suction cone is greater
than 3.5M, then use of the foot-valve is recommended (see "OPTIONAL EQUIP-
MENT" chapter).
