1. Preparation for operation
(1) Fill the paint supply system.
The viscosity of the paint normally used for this equipment ranges in 9 to 30sec/FC #4, but not
limited to viscosity. Consideration must me given to the type of paint and solvent, configuration of
the part to be coated, required film thickness and, other conditions. It is recommended that the
electric resistance value of the paint be measured before filling the supply system.
(2) Start the material delivery system to supply paint to the spray gun.
Be sure the supply pump is operated under low pressure (approx. 0. 1Mpa) using the air
regulator so that the pump will begin to cycle slowly to siphon the material and to prime the
system. Increase pump pressure gradually until the material regulator at pump outlet shows 0.2
to 0. 3 Mpa. If more precise fluid control is necessary or if the fluid flow pulsates, consider adding
a fluid regulator to the system between the material supply system and the electrostatic gun.
Confirm again that the control unit power is off.
(3) Inject the paint from the gun tip.
Turn off atomization air and pull the trigger to start flowing paint from the spray gun. Since there
may be air entrapped in the supply line continue t o flow paint until all remaining air pockets in
paint hose are removed. Paint output can be increased by turning adjuster valve at rear right
side of gun body counter-clockwise and stopped by fully turning it clockwise. When painting is
ceased, turn the valve fully clockwise to stop paint output, or curtail the pump pressure.
(4) Increase atomizing air gradually to observe the degree of atomization.
Adjust atomizing air pressure to 0.2 to 0.3 MPa and pull trigger to observe the degree of
atomization. Please understand that only enough atomization to break up the necessary paint
flow should be used. Excessive pressures will only accomplish increased over-spray and waste.
This atomizing air pressure should be adjusted to suit the nozzle and the requirements of the
process.
In addition, this gun uses inside airtight structure in order to prevent the paint come into gun body.
Small volumes of air always flow out from needle. Therefore it is not malfunction if there is sound
of airflow from needle.
(5) The spray pattern can be widened by turning the pattern width adjusting valve at the left rear of
the gun body counter-clockwise and narrowed by turning it clockwise.
Make sure that air is not leaking when returning the connection of the air hose and the trigger to
the original position. When air is discharged with the power supply on, a high voltage is
generated whether it is operating or not.
