An electric piston pump is used for high pressure painting without
air (from this process derives the term ”airless”).
The pump is controlled by an electric motor coupled with a
reduction gear.

Make sure that the electrical system is earthed
and complies with regulations.
Should anyone use an extension cable between
the unit and the socket, it must have the same
characteristics as the cable supplied (minimum
diameter of the wire 2.5 mm2)with a maximum
length of 50 mt. Higher lengths and lower dia-
meters can cause excessive voltage falls and a
bad operation of the equipment.
•Check the mains voltage corresponds to 230 Vac - 50Hz.
•The supply electric cable (H4) of the equipment is provided
without the plug. Use a plug which guarantees the plant
earthing. Only a technician or a skilled person should perform
the connection of the plug to the electric cable.

Recirculating-safety valve: when working at the
maximum pressure available, releasing the gun
trigger can cause sudden increases of pressure.
In this case, the recirculating-safety valve opens
automatically discharging part of the product from
the recirculating tube.
Then it closes so as to go back to the previous
working conditions.
Never point the spray gun towards yourselves or
other people. The contact with the casting can
cause serious injuries.
In case of injuries caused by the gun casting, seek
immediate medical advice specifying the type of
the product injected.
For all alarms, the machine shuts down and signals
the type of abnormality by means of a series of
flashes.
As for alarm No. 6, light signalling through a se-
ries of uninterrupted flashes is provided without
machine shut-down. The operator must, however,
immediately connect the unit to an adequate
grounding system.
LARIUS assumes no responsibility for failure to
comply with this requirement.

release the valve).

SPRAY ADJUSTMENT
 Slowly turn clockwise the pressure control knob to reach the
pressure value in order to ensure a good atomization of the
product.
 An irregular and marked spray on the sides indicates a low
working pressure. On the contrary, a too high pressure
causes a high fog (“overspray”) and waste of product.
 In order to avoid overthickness of paint, let the gun advance
sideways (right-left) when spraying.
 Always paint with regular parallel bands coats.
 Keep a safety and constant distance between the gun and
the support to be painted and also keep yourselves perpen-
dicular to it.
PROCEDURE TO UNLOCK THE SUCTION GROUP BALL
Should the ball of the suction group be blocked, the unit does
not suck the product anymore.
