During the operation of the compressor it is mandatory to use ear protectors while standing near the machine
Starting
Starting
Before starting operations, check if the pump has been labelled with serial number and technical data. Check all the
optionals integrity too. Keep package for further transports or stocking.
Hose connection: screw the high pressure hose and the suction hose (if not connected to a water plant) without using
an high torque.
Water plant connection: incoming water must be clean, without corrosives and, if possible, without limestone.
Maximum allowed temperature for incoming water is 60 °C. Connection requires an hose of at least ½” (Ø 13 mm internal)
and 15 bar. Shorten if possible the connection hose and eliminate every bottleneck on the hose. Minimum flow rate is 10
L/min.
Power connection: before connecting, check if the electric plant respects safety requirements and if it is able output
required power. The plant must have safety switch and earth grounding. Before connecting, turn off the pump. Don’t
connect other loads on the same point. Using long power cords, be sure that section of every cable is right for the current
flow, to avoid high temperatures and dissipations.
Air blowing: to avoid pressure oscillation due to air inside plant, it’s good eliminating all air inside plant to allow complete
water plant filling.

Working suggestions
Working suggestions
Pressure regulation device allows working at desired pressure. For pressure adjustment, turn the left handle
(“PRESS”). Minimum pressure may change, depending on incoming plant pressure.
Close “TEST” valve, as the desired pressure has been reached. In this way you’ll cut off from test the pump and all
the input plant, while you can continue checking pressure on gauge.
Don’t leave the pump “ON” with “TEST” valve closed. After a few minutes the bypass water increases temperature
and this can damages gaskets.
Water temperature: Water temperature can change pressure inside plant. Consider this factor while testing big plants
and/or with big temperature differences.
High pressure water jets can cause damages if used improperly. Avoid starting pump without connecting it to the
plant.
Work always in a safe way: respect general safety instructions, don’t let that water flows inside pump, use safety shoes
and glasses.
Respect electrical safety instructions: maintenance and inspections are allowed only with the pump disconnected
from power net. Don’t stress the power cord, change it if damaged. Keep dry every electric part.
Check if high pressure hoses aren’t been damaged. If necessary, change them with original spare parts. Work on
them only with the motor turned off and with pressure discharged.
Ensure always motor ventilation. Verify that motor can have right air flow from the chassis.
Check inlet filter before every test.
Change oil after 50 hours and then after 100 hours. Use MGF
MGF mineral oil (see below). This maintenance timing can
change with harder working conditions.

If you don’t use the pump for a long time, and / or in low temperature countries, pump a little amount of no frost solution
inside the pump. This will ensure long life to gaskets. Before restarting pump, turn the shaft from the hole on the chassis to
unblock, if necessary, valves.
Before starting, keep the key used to turn shaft.
Troubleshooting
Troubleshooting
The pump doesn’t reach the pressure: check in order: inlet filter, air inside pump, valves, inlet connection (part no.
85), gaskets.
Pressure change continuously: check air inside pump or plants. Check for dirty inside pump, valves good condition.
Check filter and gaskets.
Pressure sudden decreases: check for dirty filter and valves. Then check gaskets.
Pump is noisy: check for air suctions. Clean and move valve. Clean filter. Check water temperature. Check mechanical
parts, in particular ball bearings.
Water inside oil: change oil and look for damages on gaskets and rings. High humidity may cause this inconvenience.
Water losses from head: change gaskets and rings.
Oil losses: change oil gaskets.

Switching on, there is “hum”, but the motor doesn’t turn: immediately turn off the motor, and verify if the pump isn’t
locked. Check if voltage in the electric net is corresponding with data on the label. Remember that long power cords may
cause voltage losses. Verify voltage at the pump plug.
The motor stops suddenly: thermal protection has switched off the pump for too high temperature. Check if voltage is
correct, if pump shaft isn’t blocked or hard to turn. Wait ten minutes, then restart pump.
The motor don’t start: check electrical connections, plug and switch. If necessary, wait for thermal switch restarting.
