PREPARATION OF THE PAINT
• Make sure the product is suitable to be used with a spray
gun.
• Mix and filter the product before using it.
Make sure the product to be used is compatible
with the materials employed for manufacturing
the equipment (stainless steel, aluminium and
carbon steel ). Because of that, please contact
the supplier of the product.
Never use products containing halogen hydrocarbons (as
methylene chloride). If these products come into contact with
aluminium parts of the equipment, can provoke dangerous
chemical reactions with risk of explosion.
• 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.
• Point the gun at the solvent tank and press the trigger so as
to recover the residual solvent.
• Close the pressure setting knob (F3).
Do not set the pump to work without product,
because this could spoil its gaskets.
Absolutely avoid to spray solvents indoors. In
addition, it is recommended to keep away from
the pump in order to avoid the contact with the
solvent fumes.
• Now the machine is ready. Should you use water paints,
besides the solvent wash, a wash with soapy and then clean
water is suggested.
WASHING OF THE NEW EQUIPMENT
• The equipment has already been adjusted at our factory with
light mineral oil left inside the pumping group as protection. As
soon as the connections have been carried out, before putting
the product in the tank, it is necessary to rinse the pump by
means of the circulation of solvent (thinner for paints).
• Clean hoses (F1) and (F2) by blowing compressed air before
connecting them.
• Make sure that the atomising air supply is shut off.
• Rotate the pressure setting knob (F3) slightly clockwise so
that the machine operates at minimum power.

SPRAY ADJUSTMENT
• Slowly turn the knob on the flow regulator clockwise, until
a pressure is obtained that guarantees good atomisation 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.
HCLEANING AFTER THE
SPRAY PAINTING OR IN
CASE OF PRODUCT CHANGE
• Reduce product pressure to the minimum (0,5-1 bar) by
means of knob (H1).
• Use knob (H2) to set the air atomisation knob to zero.
• Disconnect the return hose (H4) from tank (H3) and introduce
it into an empty can for recuperating the product.
• Open the recycling tap (H5) and let the pump work until the
tank and the pump itself have been emptied.
• Close the recycling tap (H5).
• Put back the recycling hose (H4) into the tank (H3).
• Pour some solvent in the tank (H3).
• Open the recycling tap (H5), set the product pressure at the
minimum value by means of the knob (H1).
• The pump will be set to work. Let the solvent recycle for a
short time and then close the recycling tap (H5).
• Unscrew the atomizing head (H6) and rinse it with the solvent,
put it back and by means of the spray gun discharge in a tank
the product left until the solvent comes out.
• 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 perpendicular
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.
