2. Starting operation
(1) Switch on the power to control unit. When trigger is pulled, red lamp is illuminated to indicate
high voltage is applied at the gun head. High voltage is not generated when switch at gun grip is
off.
Before switching on the control unit, confirm again that the unit is securely grounded through
a grounding wire.
Never wear gloves without a hole in the palm to handle the spray gun. Never wear rubber
soled shoes during operation of an electrostatic gun. The gun grip is at zero potential if the
control unit is grounded and there is no danger of electric shock if the gun grip is held by a
bare hand.
(2)
Start the painting operation. Adjust the voltage level on the control unit to suit conditions.
Adjustment range is 20 to 60kV.
Before starting operation, check to see if the grounding resistance of the object to be coated
is under 1M
Ω
.
Do not touch object to be coated with the metal part of the nozzle. Normally potential at the
nozzle is automatically lowered as it approaches any grounded object, but there is a slight
danger of sparking in a case of a rapid approach gun to ground.
Do not touch the nozzle during high voltage is applied.
(3) When not painting, always switch off the power to the control unit.
Never leave the spray gun alone while the power switch on the controller is on.
If paint of low electric resistance (2M
Ω
or lower), is to be used, the paint supply pump should
be installed on an insulated stand. In this case, high voltage is also present at the pump.
Never touch the pump when the high voltage is on. When necessary to service the supply
equipment be sure to switch off the hi voltage by turning off the switch on the controller, then
be sure to ground the system as there is a good possibility that residual high voltage will be
retained.
3. Finishing operation (When re-starting within 24 hours is expected)
(1) Switch off power to control unit by one hand, and holding the spray gun in the other hand. Do
not place the gun on the floor or on a work bench.
(2) Lower the atomizing air pressure to 0Mpa at the regulator.
(3) Lower the air pressure supplying the delivery system to 0MPa.
(4) Pull the spray gun trigger to release remaining fluid pressure.
(5) To discharge remaining voltage, carefully touch the nozzle electrode to ground keeping the
trigger open.
