• Pulling the trigger many times during operation, may cause carpel tunnel syndrome. Always rest, in case of tiredness.

IMPROPER USE

• Never point gun towards people or animals.
• Never exceed maximum working pressure or maximum operating temperature.
• Always release air and fluid pressure before cleaning, disassembling or servicing. Otherwise, remaining pressure can cause bodily injury due to improper operation or scattering of cleaning liquid.
• Tip of fluid needle set has a sharp point.Do not touch the tip during maintenance to avoid Paint cup
• Never use this gun to spray foods or chemicals. Otherwise.foreign substance, could cause corrosion of fluid passages which could adverssely affect health.
• Never alter this spray gun, to avoid insufficient performance and damage.
• If something goes wrong, immediately stop operation and find the cause.Do not use again, until you have solved the problem.
• Do not enter working areas, where robots, reciprocators, etc. are used,until they have been turned off. Otherwise, they could cause injury.

KNOW YOUR SPRAY GUN

NOZZLE SIZE RECOMMENDATION

Please refer to Paint Manufacturer’s recommendations.

NOZZLE SET REPLACEMENT

Disassembly of nozzle set

• Turn the Fluid Adjustment Knob(D) counter­clockwise to remove Fluid Needle and Needle Spring.
• Remove the Air Cap Set(A).
• Reverse for assembly and remember to tighten the Fluid Nozzle to prevent fluid leak.
  NOTE:
  Replace the whole set of Air Cap, Nozzle, Fluid Needle at the same time.
  Unscrew the Fluid Nozzle with the Adjustment Wrench .

ASSEMBLY

• Install the Filter.
• Screw the Paint Cup(B) clockwise.
  NOTE: I f you are using other paint cups, please choose a compatible adapter. The paint cup inlet thread size is M16Xl.5.(An adapter for 3M PPS Series 2.0 is included.)

Optional

• Connect the Air Pressure Regulator to the Inlet Connector(G) and then the Oil-Water Separator.
• Use a 1/4″ air hose to connect with the Oil-Water Separator or connect directly to the Inlet Connector(G).

STARTUP

• Turn the Air Pressure Regulator Knob clockwise to make sure the air inlet is closed.
• Turn the Fluid Adjustment Knob(D) clock­wise to the minimum to prevent the needle from moving.
• Turn the Pattern Adjustment Knob(C) coun­terclockwise to fully open the fan.
• Turn the Air Adjustment Knob(F) counter­clockwise to fully open it.
• Hold the Gun Trigger(E).Then turn the Air Pressure Regulator Knob counterclockwise to raise the air pressure up to 3.0bar.
• Turn the Fluid Adjustment Knob(D) to gauge #2.
• Change the spray pattern at vertical or horizontal by rotating the Air Cap at 90°.
• Mix coating material by Manufacturers’ instructions and pour into the Paint Cup.

TEST SPRAY

1. Test the static and dynamic spraying effect on the test paper.

2. . Adjust knobs to get the right coating result and pattern.

   • a. If the finish is too dry, turn the Air Adjustment Knob(F) clockwise to reduce the inlet air pressure.
   • b. If the finish is too wet, turn the Fluid Adjustment Knob(D) clockwise to reduce the fluid flow.
   • c. If the atomized particles are too coarse, turn the Air Adjustment Knob(F) counterclock­wise to increase the inlet air pressure.
   • d. If the atomized particles are too fine, turn the Air Adjustment Knob(F) clockwise to reduce the inlet air pressure.
   • e. If the spray pattern is too large, turn the Pattern Adjustment Knob(C) clockwise to reduce the size.
     NOTE:
     Refer to the Trouble Shooting for more information.

3. Record relevant data on the test card for next use (optional).

SPRAY

1. Maintain a distance of 6-8 inch between the spray gun and the object surface. Keep the spray gun perpendicular to the surface during movement. Bending or tilting the spray gun will cause uneven spraying.
2. Slightly press the trigger to start stroke, then press hard, to get a smooth gun activation and save paint. (Practice makes perfect!)
3. To stop spraying, slightly release the trigger to end stroke, then release the trigger completely.
4. The speed of moving the spray gun is recommended to be about 12-15 inch per second.
5. When spraying large areas, it is recommended to use a reciprocating method. The overlap area of the spray width is about 50%.
6. After using the spray gun, be sure to turn off the air source. Then hold the trigger to release the air pressure.

CLEAN UP

1. Recycle the remaining paint into the paint container.

2. Pour in neutral cleaning solution (pH 6 to 8), shake lightly and spray it out. Repeat multiple times until the mist coming out is clean.
   NOTE: Do not immerse the spray gun completely in any solvent or cleaning solution, as this will damage the spray gun lubricant and shorten its lifespan.

3. Disconnect the air hose, disassemble the Paint Cup(B), Air Cap Set(A) and Fluid Adjustment Knob(D). Use cleaning kit and accessories to com­pletely clean the gun.

   • a. Clean the air cap, nozzle and fluid needle by brushing the outer surface.
   • b. Clean the air cap hole with a toothpick. (if necessary) NOTE: If using metal wire or hard tools, be careful not to scratch the air cap hole to become fuzzy, resulting in deformation of the spray pattern.
   • c. Clean the Paint Cup and Gun Body by wiping the surface with a damp cloth.

4. After cleaning, reconnect to the air hose, turn up inlet air pressure and hold the Gun Trigger(E) to dry the inside of the spray gun.

ACCESSORIES INSTRUCTIONS

Air Pressure Regulator

Set Up

Connect the air outlet end (upper side) to the gun and tighten the joint with a wrench.

Adjustment

Turn the Air Pressure Regulator Knob clockwise to reduce the air inlet or counterclockwise to raise the air pressure.

CAUTION:

The air source should not exceed the pressure gauge range to prevent damage to the pressure gauge, which may cause the pointer to deviate and not return to zero.

Oil-Water Separator
Set Up

Connect the air outlet end (upper side) to the Air Pressure Regulator.

WARNING:

This product can expose you to chemicals including Di (2-ethylhexyl) phthalate, lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to
