Operation
22 309298J
Spraying
1. Apply a minimum of 50 psi (3.5 bar, 0.35 MPa) air
pressure to the cylinder air fitting (CYL) to activate
the on/off sequence of atomization air (A2) and fluid
(P1). See F
IG . 12..
2. Turn the gun functions off and on by using the air
solenoid valves on the cylinder (CYL) and turbine
(TA) air supply lines.
3. To change to a lower voltage setting, activate the
solenoids controlling the KV1 and KV2 ports. See
Changing the kV Setting on page 7.
Triggering the Fluid Alone
1. Shut off and relieve the air pressure to the atomiza-
tion (A2) air line, using the bleed-type air shutoff
valve.
2. Apply 50 psi (3.5 bar, 0.35 MPa) air pressure to the
cylinder air fitting (CYL) to trigger the fluid.
Shutdown
1. Relieve the pressure.
2. Flush and clean the equipment. See Maintenance
on page 23.
WARNING
Electric Shock Hazard
To reduce the risk of electric shock, do not
touch the gun electrode or come within 4 in.
(10 cm) of the nozzle during gun operation.
WARNING
Fire and Explosion Hazard
If any fluid leakage from the gun is
detected, stop spraying immediately. Fluid
leakage into the gun shroud could cause
fire or explosion and result in serious injury
and property damage. See Check for Fluid
Leakage on page 28.
WARNING
Skin Injection Hazard
To reduce the risk of a fluid injection injury,
always follow the Pressure Relief Proce-
dure on page 18 when you stop spraying
and whenever you are instructed to relieve
the pressure.
