HPP ELR 164/90 (1330 об/мин) [29/168] Behavioural norms for using the jet pipes

malfunctions of a high pressure system.

Before starting the system it is advisable to check the following:

• Level of the system’s liquids (pump and motor oil, coolant)

• Cleanliness of the pump’s suction lters

• That it is fed correctly

• The good condition of pipes and connections – there must be no signs of wear

• That the electrical parts are in good condition and protected to standards

• That all the protections envisaged are active.

Except for pressure regulation, no other work must be done while the system is operating (e.g.

checking that the ttings are watertight, checking the high pressure pipes, etc.)

Any malfunction found before or during work must be reported immediately and veried by

competent personnel.

Pressure must be zeroed and the pump switched o before any such operations are carried out.

BEHAVIOURAL NORMS FOR USING THE JET PIPES

The operator should behave according to good sense and responsibility, placing his safety, and that of

others, before everything else.

The operator must have personal protective gear, such as a hard hat with protective eyeshade, rubber

boots and waterproof clothes.

Appropriate clothes will protect eectively against sprays of water but not against the direct impact of

a jet of water which is why we recommend following these few simple rules:

• Organise yourselves in teams of two to provide reciprocal and immediate assistance in the case of

need and so you can take it in turns when work is long and arduous.

• No objects must be left in the working area that come within the range of the high pressure jet

because dangerous situations could be created if such objects are accidentally hit by it.

• Always aim the jet of water in the direction of the working area, also during tests and checks.

• The operator must pay attention to the trajectory of removed waste and set up adequate barriers to

protect whoever or whatever may be exposed to such a jet.

• When the operator is working he must not be disturbed for any reason. Whoever has to enter the

working area and who has authorisation to do so, must wait until the operator nishes what he is

doing and only then may he make his presence known.

• The high pressure system must not be started or pressurised unless all the workers have been

notied.

MAINTENANCE AND SAFETY

The high pressure system must be serviced by qualied personnel, following the procedures and at

the times indicated by the Manufacturer.

Use suitable and specic tools to assemble and remove the various components.

Use always and only original spare parts to guarantee total reliability and safety.
