• Do not point the jet towards oneself or other people in order to clean off clothing or
footwear.
• Do not point the high-pressure jet towards materials, which contain asbestos or other harmful
substances.
• Make sure that the pump's moving parts are adequately protected and that they are not
accessible to unauthorised personnel.
• Do not come within reach of the pump's moving parts, even if they are adequately protected.
• Do not remove the protective devices of the pump's moving parts.
• Do not carry out any maintenance on the pump if it is in use.
• Follow the instructions in the "Designated Uses" section.
• Do not modify the conditions of the installation of the pump, especially its attachment and its
hydraulic connections.
• Do not operate any taps installed on the pump if they are not connected to an application that
prevents the accidental leakage of the liquid being pumped.
• Do not tamper with controls and safety devices.
• The connection of the machine that incorporates the pump to the mains electric supply must
be carried out by a Qualified Electrician according to the current regulations in the country
where it is to be used.
• If the machine that incorporates the pump operates with a combustion engine, it must not be
used in enclosed spaces.
5.1 PRELIMINARY PROCEDURES
fi«
CAUTION
• Complete the Manufacturer's recommended preliminary procedures for the machine that
incorporates the pump.
• Check that all the delivery parts are closed or connected to applications, which are closed
(for example, closed tap or closed sprinkler lance).
• Do not exceed the maximum level of accumulator inflation pressure (when present), indicated
in the following table, at any time.
• A Skilled Technician must complete the special maintenance procedures.
a) When the pump is not in use, check that the oil level either corresponds to the reference notch
on the volumetric compensator (4) or is visible from the level cap (also see fig. 6), according to
the type of pump.
Remember that the level of the oil must always be checked when the pump is not in use and has
cooled down completely.
Refer to the types of lubricants listed in the "FEATURES AND TECHNICAL SPECIFICATIONS"
section if it is necessary to top up the oil. Use SAE 30 non-detergent oil type.
fi«
CAUTION
• Pumps BP 40/15, BP 60, P48 and P48 AP do not have a volumetric compensator therefore,
contact a Skilled Technician if a top up is necessary
b) Check that the inflation of the pressure accumulator, if present, is correct using a common
compressed air gun with a pressure gauge, i.e. the type used to check the pressure of motor vehicle
tyres.
Inflation depends on the range of pressure that the pump must operate in, according to the following
