 Use always accessories in good state and with the characteristics the equipment has, if some accessory presents or displays malfunctions in its operation immediately replace it. Teflon or sealant are always recommended in connections between two elements to avoid air leaks. Do not connect too long of a hose , no longer than 15 ft. is recommended.

 Gas accumulation can cause some type of explosion, work in open and ventilated areas. The use of a mask is recommended to avoid the excessive inhalation of pulverized products.

To perform any maintenance work it is necessary to disconnect the pneumatic line. If for any reason it is required to replace any pieces of gun we suggest you replace it with an original, never use similar parts or other manufacture.

Never operate equipment if you are under the influence of alcohol or any drug. If you show exhaustion suspend the use, it can cause an accident.

ASSEMBLY

Hose connection is 1/4”; a hose of the same size will need to be attached to the Air Inlet Joint.

1. 1. Initially perform the following actions:
      a. Use the spanner wrench to tighten the fluid nozzle.
      b. Install and tighten the paint cup.
      c. Check air lines and fittings to ensure that they are clean and damage free before connecting to gun.
      d. Flush gun thoroughly with cleaning fluid

2. Pattern Adjustment
   Use the pattern (fan) adjustment knob on the left side of the gun to obtain the desired fan pattern.

3. Air Volume Adjustment
   Use the air volume adjustment knob to obtain the desired fluid flow volume.

4. Fluid (paint) adjustment
   Use the fluid control knob to obtain the desired fluid flow volume

Attached Cup by gently screwing on clockwise hand tight.

Before you start work with a spray gun, be sure to have clean air and no moisture particles of water/oil in order to achieve satisfactory results. Addition of a water filter or inline dessicant filter is suggested.

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 Air Adjusting Knob.

AIR Volume ADJUSTMENT: Turning the Air Adjusting valve clockwise will decrease the air volume. And counter-clockwise will increase the air volume.

PATTERN ADJUSTMENT: Turning Pattern Adjusting Knob to the right until tight will make spray pattern round, or turning left make spray pattern ellipse.

Fluid (Paint) ADJUSTMENT: Turn the Paint Adjusting Knob clockwise will decrease the volume of fluid output and conter-clockwise will increase fluid output.

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 perpendicular with spraying area then move it paralel for several times. Stopping gun movement in mid-stroke will cause a build up of paint and result in runs. Do not fan the gun from side to side while painting. This will cauzse a build-up of paint in the center of the stroke and an insufficient coating at each end.

3. Trigger 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 wil 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.

OPERATION

TIP#1:
Always keep gun at right angles of work; always move gun first, then trigger

TIP #2
Accurately adjusting your spray gun inlet pressure using a pressure regulator at the spray gun

1. “open” the air adjustment valve on the gun.
2. With your gun trigger depressed half way (air only) adjust your air inlet pressure regulator to the desired inlet pressure to obtain the desired air cap pressure based on the table to the right.
3. Spray a test pass on a piece of masking paper, cardboard, etc. to check for proper atomization and desired spray ability.
4. Fine tune using the air adjustment valve on on the gun.

MAINTENANCE

Changing of air cap: To ensure proper function and operation always change the fluid nozzle and needle as a matched set.

Changing of needle packing: The needle is sealed using a Teflon packing. To change the packing remove the fluid needle, fluid nozzle and the packing nut.
