WORKING PRINCIPLE
The LARIUS DALÍ unit is dened as an “electric diaphragm pump”.
An electric diaphragm pump is used for high pressure paint
spraying without air (known as “airless”).
The pump is powered by an electric (internal combustion) motor
coupled with a cam shaft. The shaft acts on the hydraulic piston
as it pumps oil from the hydraulic case and sends the suction
diaphragm into brillation. When the diaphragm moves, it cre-
ates a vacuum. The product is sucked up, pushed towards the
pump outlet and sent to the guns through the exible hose . A
hydraulic valve on the hydraulic case head allows setting and
checking the pressure of the paint product at the pump outlet.
A second hydraulic safety valve to avoid over-pressure, ensures
total equipment reliability.

SETTING-UP
COLLEGAMENTI DI TUBO FLESSIBILE E PISTOLA
• Connect the high pressure flexible hose to the pump and
to the gun, ensuring to tighten the fittings (the use of two
wrenches is suggested).
• It is recommended to use the hose provided with the standard
kit (ref. 35017).
COLLEGAMENTO DELL'ALIMENTAZIONE ELETTRICA
• Check the plant is earthed.
NEVER use sealants on fittings’ threads.
NEVERusea damagedor a repairedflexible hose.
• The supply cable (H2) is provided without 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.
• Check the mains voltage corresponds to the equipment’s
rating (H1).
Should anyone use an extension cable between
the tooling and the socket, it must have the same
characteristics as the cable supplied (minimum

Therefore, wash with diluent before sucking the product.
• Lift the suction pipe and dip it into the solvent tank (H5).
• Ensure the gun (H6) is without nozzle.
• Open the re-circulation tap (H7). Turn the unit ON-OFF switch
(H8) on the "ON"position.
• Rotate the pressure setting knob (H4) slightly clockwise so
that the machine operates at minimum power.
• Point the gun at a container keeping the trigger pressed (so
as to drain the oil inside) till a clean solvent comes out. Now,
release the trigger.
• Remove the suction pipe and take away the solvent tank.
• Point the gun at the solvent tank and press the trigger so as
to recover the residual solvent.
• As the pump idles, press the ON/OFF switch (H3) on the
position "OFF" to stop the tooling.
Absolutely avoid to spray solvents indoors. In
addition, it is recommended to keep away from
the pump in order to avoid the contact between
the solvent fumes and the electric motor.
• Now the machine is ready. Should you use water paints,
besides the solvent wash, a wash with soapy and then clean
water is suggested.
• Insert the gun trigger lock and assemble the nozzle.
PREPARATION OF THE PAINT
• Make sure the product is suitable to be used with a spray
gun.
• Mix and lter the product before using it. For ltration, use
CLOSE-MESH (ref.214) and LARGE-MESH (ref.215) LA-
RIUS METEX braids.
Make sure the product to be used is compatible
with the materials employed for manufacturing
the equipment (stainless steel and aluminium).
Because of that, please contact the supplier of
the product.

WORKING
START OF THE PAINTING OPERATIONS
• Use the tooling after performing all the SETTING UP ope-
rations above described.
• Dip the suction pipe (I1) into the product tank.
• Open the re-circulation valve (I2).
• Press the ON/OFF switch of the equipment and turn a little
the pressure control knob (I3), so as the machine works at
the idle speed.
• Make sure the product recycles from the return tube (I4).
• Close the re-circulation valve.
• At this point the machine will continue to suck the paint
product until the delivery hose is completely full. Afterwards,
the product will re-circulate automatically.
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.
NEVER point the spray gun at yourselves or at
other people. The contact with the casting can
use serious injuries. In case of injuries caused by
the gun casting, seek immediate medical advice
specifying the type of the product injected.
