2. WARNING
1)Never point the nozzle of spray gun at human body. (Injection from the gun nozzle
has high paint pressure, which can cause penetration of the skin and seriousinjuries.)

2)

Always shut off pump, release fluid pressure of gun, hose, and pump, and make sure scaleon the pressure gauge is pointing zero before installing and uninstalling paint hose.

3)

Operate spray gun under the proper fluid pressure less than 15Mpa.

4)Spray gun, hose and pump MUST BE GROUNDED before operating the airless spray system
to avoid ignition to solvent due to static electricity originated from high speed spray.

5) Operate spray gun and pump under the lowest pressure when cleaning spray gun,hose and pump with thinner to keep operator safe.(Pump air pressure 0.05Mpa）-1-3. INSTALLATION AND OPERATING
1) Connect paint hose fittings to inlet of paint (25) securely.
Connect air hose fittings to inlet of atomizing air (31) securely.
Control atomizing air with Two Directions Auto Valve.
Use Three Directions Auto Valve or Five Directions Auto Valve to control the air to turn ON/OFFｇｕｎ. (Refer to installation circuit diagram)
2) Install Combi Nozzle packing (5), Air Combi Nozzle (4), Air Orifice (3), and Cap Bushing (2)respectively to spray gun point and tighten Cap Hand E (1) securely.
3)

Set up fluid pressure in the lowest pressure according to each liquid or paint.
The lowest pressure which eliminates paint tail from the nozzle is the best for atomizing air.
(Increase air pressure gradually from 0 PSI with adjusting regulator.)*Consult with a dealer in case that paint tail does not eliminate by using special material.

4)

After use, Remove them up to Combi Nozzle Packing (5) from spray gun when you cleanse
inside of the gun with thinner. Running the pump by low pressure, and circulate thinner into
the spray gun. Especially cleanse Air Combi Nozzle (4) thoroughly.
Clogging might cause improper painting result.
*Refer to instruction for cleansing, Cleansing Validation on page 5.
