Starting cycles generate brief voltage drops. Interference with other equipment/machines may occur in case of unfavourable mains system conditions.
Malfunctions are not to be expected for system impedances below 0.32 ohm.
Connecting to the water supply
(see figure F)
Note: Rated output pressure can only be achieved, if the flow
rate at the water input is sufficient. The flow rate is sufficient
if a 10 litre bucket can be filled in less than 1 minute.
CAUTION: Permanent operation with lack of water at the wa-
ter input can damage the pump.
NOTE: For a sufficient water supply use a short hose with a di-
ameter not thinner than 1/2" (13 mm). Hoses longer than
10 m should have a diameter of 3/4" (19 mm). Open the wa-
ter tap completely. All connections must be tight. Clean the
water filters periodically (see chapter Maintenance).
– It is recommended to use always an external water filter
(accessory). Check water filter for tight assembly.
– If necessary, screw on an hose adapter (not supplied with
the machine).
– Connect a suitable water hose, best with 1/2" (13 mm) or
3/4" (19 mm) diameter.
– Open the water tap completely and check all connections
for tightness.

Connecting to the mains (see figure G)
NOTE: Rated output pressure is only available, if the machine
is connected to a stable mains voltage. Using a long connec-
tion cable with a thin wire cross section, an uncoiled cable
drum, operating other machines concurrently at the same cir-
cuit or voltage fluctuations outside accessible tolerances im-
pede motor starting or result in low output pressure.
Bleeding high-pressure washer and
hoses (see figure G)
NOTE: Bleed the unit each time the water hose is connected
to the water tab according the following procedure:
Leave the main switch at OFF (0) position.
Disconnect the lance from the gun.
– As soon the trigger of the gun is operated, air and water ex-
its noisily. Hold the trigger until water exits steadily from
the gun. Release the trigger.
– Reconnect the lance.
– Switch on the machine for operation.
– Press the safety release and operate the trigger of the gun.
