10.0 - MAINTENANCE, INSPECTIONS AND CHECKS, REPAIRS,

When carrying out maintenance operations, inspection and checks, repairs, it is advisable to wear the individual
protection devices listed in this manual.
All maintenance operations, inspections and checks, repairs must be carried out with the greatest attention and
with the Rotary blades vacuum pump off and with the power take-off disconnected.

10.1 - CLEANING

10.1.1 - BODY WASHING

If sewage enters the Rotary blades vacuum pump, the inside of the body must be washed immediately, by making it suck in diesel
or fuel oil through the suction pipe with the Rotary blades vacuum pump in compression phase. After this operation make it suck in
oil. The same operation should be carried out when the Rotary blades vacuum pump has to remain inactive for a long time. In this
case it is necessary to disconnect the suction and delivery tube connected to the valves and seal the manifold lid because the gases
that forms inside the tank, pouring in the Rotary blades vacuum pump, cause rust inside the body, which can cause breakage of the
blades when the machinery is restarted.
In order to avoid rust formation, do not use water.
If the body is washed after it is disassembled, it is advisable to carry out a preliminary wash with detergent (e.g. thinner).

10.1.2 - FLUSHING KIT (KPS)

There is a 1/4Gas hole on the intake manifold (closed by a dowel on the standard version), where it is possible to inject diesel fuel
to clean the pump. An optional kit will be provided with plastic tank and tap to place on the tank for such operation. Lacking the kit,
just remove the 1" 1/2Gas cap on the manifold and input the diesel fuel from the top hole, causing it to fall out from the output curve.

10.1.3 - OIL TANK WASHING

Wash the oil tank at least once a year with appropriate detergent.

10.1.4 - VALVES WASHING AND CLEANING

Wash and clean the valves at least once a month, unscrewing them from the Rotary blades vacuum pump and cleaning them with
water or non-corrosive detergents.

10.2 - VALVES CHECKING

Regularly check that all the valves, for both overflow and pressure/vacuum, are still working efficiently.

10.3 - BLADES GENERALITIES

All the Rotary blades vacuum pumps are fitted with special blades. These blades have optimum mechanical characteristic and
considerable resistance to heat and prolonged use.
A part for normal wear, it may be necessary to replace the blades due to incorrect use of the Rotary blades vacuum pump. The most
frequent causes are heat, lack of lubrication, excessive wear, sewage entrance, high pressure or vacuum, or formation of rust inside
the body due to prolonged inactivity.
Too high heat causes bubbles to form on the surface of the blades, increasing their thickness and preventing them from coming out
freely from the rotor slots; the layer of material of which the blade is made may also come apart. Lack of lubrication means the blades
are completely dry like the inside pump. This increases their fragility and causes them to break lengthways.
The same type of breakage can be caused by entrance of sewage or by a too high working pressure or by an excessive wear. A too
high vacuum causes the blades to beat against the cylinder with consequent damage to the outside of the blades. Moreover, the lining
becomes wavy.
