• Carry out the preliminary checks recommended by the Manufacturer of the machine with the pump.

• Check all the delivery hoses are closed or are connected to a closed application (such as a closed tap or a

spray gun in the closed position).

• Do not exceed the maximum inflation pressure for the accumulator (when applicable) indicated in the table

below.

a) When the pump is at a standstill, check the oil level is not above the notch on the case and is no more

than 2-3 mm below it (see Fig. 4).

Always check the oil when the pump is at a standstill and has cooled down completely.

Refer to the list of lubricants in the section on

oil.

not have a volumetric compensator.

b) Check the pressure accumulator is inflated correctly using a standard compressed air gun fitted with a

pressure gauge, such as those used to check tyre pressure (20/20 and 25 only).

The inflation depends on the pump's operating pressure range, as shown the table below:

cauTion

• In applications where the pump is driven by a cardan shaft, avoid thrust against the pump shaft caused

by incorrect cardan operation (poor greasing of sliding parts, incompatible rotating angles with the type of

cardan).

• Make sure ice does not form inside the pump when working at very low temperatures.

• Complete all routine maintenance, especially with regard to the oil.

WarninG

• Do not connect to the mains water supply.

• All hoses must be secured to their couplings with clamps.

Refer to Fig. 3 for a general layout of a typical machine with the pump and to the following table for the

hydraulic connections for the suction, delivery and by-pass lines:

1. Tank

2. Suction filter

3. Suction circuit

4. Pump

a) For use with a spray gun:

- Completely unwind the high-pressure hose;

- Connect the high-pressure hose to the delivery coupling using a clamp;

- Connect the gun to the high-pressure hose and make sure the lever is shut.
