OPERATIONS
• Make sure that the product and the thinner are suitable to be sprayed. Make sure that the thinner is suitable to be used with
the product to be sprayed. Make sure that the product has been duly filtered and mixed.
• The nozzle and the filter shall be suitable for the gun, according to the product to be sprayed and to the operation to be
carried out (refer to the assembly tables and instructions) .
I.1 PRODUCT PREPARATION
• This table is for indication only. The adapatability of a certain product to a determined nozzle changes according to different
aspects. If previous experiences are lacking, a practical test is always necessary. A nozzle, which has been duly chosen, will
give as result a neat jet without pulsations and gives a perfect praying of the product.
• An inconstant spray, slightly marked on the sides, might indicate a too low pressure. If the maximum pressure has already
been reached, it is then necessary to choose a smaller nozzle. With the exclusion of some products, which can be atomized
at high pressures only, it is advisable not to exceed the value of 140-170 Atm
(high pressure could cause mist).
• Use the provided lubricant ( I1 ) ( rif. 16325 ) in order to make
the sliding of the piston easier inside the sealing pack and
interpose oil to air.
before using the equipment, check all the connection
fittings on the various components
(pump, flexible
hose, gun, etc.)
• Considering an equal speed of application, a nozzle with a spraying angle of 20° lays down a film having a thickness
which is averagely double in respect to the one which can be obtained with the same nozzle with an angle of 60°.
• An excessive diameter of the angle could result in an anomalous pressure drop.
• When ordering a nozzle, choose accurately the reference number on the list of the nozzles.
• Use the equipment only after having completed all the
adjustment operations described in the previous paragraph.
I.2 START SPRAYING OPERATIONS
• When the product has been duly mixed, the product will flow from the recirculation hose ( H2 ).
If the product does not flow, this means it is too thick and it is necessary to dilute it again until a correct flow is achieved.
Let the product flow for a short time. At this point, the machine is ready to work.
