Important Safety Instructions
1. For toxic vapors produced by spraying certain materials can create intoxication
and serious damage to health. Always wear safety glasses, gloves and
respirator to prevent the toxic vapor hazard, solvent and pointing paint coming
into contact with your eyes or skin.
2. Never use oxygen, combustible or any other bottle gas as a power source or
would cause explosion and serious personal injury.
3. Fluid and solvent can be highly flammable or combustible. Please Use the tool
only in well-ventilated area, and avoid any ignition sources, such as smoking,
open flames and decrial hazard.
4. Disconnect paint gun from air supply hose before doing tool maintenance and
during non-operation, for emergency stop and prevention of unintended
operation, a ball valve near the gun to air supply is recommend.
5. Use clean, dry and regulate compressed air rated at 3.0~4.0bar, never exceed
maximum permissive operating pressure 8.3 bar(120psi).
6. Never use homogenate hydrocarbon solvent, which can chemically react with
aluminum and zinc parts and chemically compatible with aluminum and zinc
parts.
7. Never point gun at yourself or others at any time.
8. Before operating the paint gun, ensure all the screws & caps are securely tightened to prevent leaking.
9. Before painting, make inspection for free movement of trigger and nozzle to insure tool can operate well.
10. Never modify this paint gun for any applications. Only use parts, nozzles and accessories recommended
by the manufacturer.
Instructions for Operation
Preparation
1. After unpacking the paint gun, inspect carefully for any damage that may have occurred during transit.
Make sure to tighten fittings, bolts, etc., before putting unit into service.
2. Thoroughly mix and thin paint in accordance with the paint manufacturer’s instructions. Most materials
will spray readily if thinned properly.
3. Strain material through filter, cheese cloth or a paint strainer.
4. Fill the canister about ¾ full and start the air compressor.
WARNING Do not exceed Maximum Pressure of Spray Gun or any other parts in the compressor system.
5. After connecting the gun to the air supply, please make sure that the fluid cap, container and air hose
have been connected tightly to the spray gun.
6. Set up a piece of cardboard or other scrap material to use as a target and adjust for best spray pattern.
WARNING Never aim or spray at yourself or anybody else as it could cause serious injury.
7. Test the consistency of the material by making a few strokes on a cardboard target. If material still
appears too thick, add a small amount of thinner. THIN WITH CARE! Do not exceed paint
manufacturer’s thinning recommendations.

Adjustment
The desired pattern, volume of fluid output and fine atomization can easily be obtained by regulating the
Pattern Adjusting Knob, Fluid (PAINT) Adjusting Knob and AirAdjusting Knob.
Adjusting pattern: Turning the Pattern Adjusting Knob to the right until tight will make spray pattern round
and turning it to the left will make spray pattern ellipse.
Adjusting volume of fluid output: Turning the Fluid (PAINT) Adjusting Knob clockwise will reduce the
volume of fluid output and turning it counter-clockwise will increase fluid output.
Adjusting air volume: Turning the Air Adjusting valve clockwise will reduce the air volume and turning it
counter-clockwise will increase the air volume.
Operation
1. Begin spraying. Always keep the gun at right angles to the work.
2. Keep the nozzle about 6 to 12 inches from the work surface. Grip the gun keeping it perpendicular with
spraying area then move it parallel for several times. Stopping gun movement in mid-stroke will cause a
buildup of paint and result in runs. Do not fan the gun from side to side while painting. This will cause a
buildup of paint in the center of the stroke and an insufficient coating at each end.
3. Trigger the gun properly. Start the gun moving at the beginning of the stroke BEFORE SQUEEZING
THE TRIGGER and release the trigger BEFORE STOPPING GUN MOVEMENT at the end of the stroke.
This procedure will blend each stroke with the next without showing overlap or unevenness.
4. The amount of paint being applied can be varied by the speed of the stroke, distance from the surface
and adjustment of the fluid control knob.
5. Overlap strokes just enough to obtain an even coat.
NOTE: Two thin coats of paint will yield better results and have less chance of runs than one heavy layer.
6. Use a piece of cardboard as a shield to catch overspray at the edges of the work to protect other
surfaces.
Maintenance
Incomplete cleaning could cause function failures and a degradation of the fan form.
1. Remove any remaining paint by pouring it into another container.
2. Disassemble the spray gun making sure to remove the needle before disassembling the nozzle to avoid
damage to the housing of the nozzle closure.
3. Clean all the paint passages and the nozzle. Clean the other components using a brush soaked in
solvent.
4. Reassemble the spray gun and spray a small quantity of solvent to eliminate all the residues in the paint
passages. WARNING:
NEVER USE METAL OR OTHER OBJECTS THAT COULD DAMAGE THE HOLES IN THE NOZZLE AND CAP. NEVER
IMMERSE THE SPRAY GUN COMPLETELY IN SOLVENT. NEVER USE COMPONENTS OR PARTS THAT ARE NOT
MANUFACTURER ORIGINALS.

Storing
zWhen not using spray gun, turn the fluid adjustment knob counter-clockwise to open which will reduce
spring tension on needle fluid tip.
zSpray gun MUST BE well cleaned and lightly lubricated.
Troubleshooting
Symptom Problems Solution
Fluttering or
spitting

3. Loose fluid inlet connection.
4. Loose or damaged fluid tip/seat.
5. Dry or loose fluid needle packing nut.
6. Air vent clogged
1. Add material into container.
2. Hold more upright.
3. Tighten.
4. Adjust or replace.
5. Lubricate and or tighten.
6. Clear vent hole.
Pattern is arched.
1. Worn or loose Fluid nozzle.
2. Material buildup on Air cap.
1. Tighten or replace Fluid nozzle.
2. Remove obstructions from holes,
but don’t use metal objects to clean it.
Patternisnot
evenly spread.
1. Material buildup on Air cap.
2. Fluid nozzle dirty or worn.
1. Clean or replaceAir cap.
2. Clean or replace Fluid nozzle.
The center of pattern is
too narrow.

1. Regulate material viscosity.
2. Reduce air pressure.
Pattern width of fan
shape is too narrow
1. Material too thick.
2. Atomization air pressure too low.
1. Regulate material viscosity.
2. Increase air pressure.
Air leaking from air cap
without pulling trigger
