Operation (continued)
Note: When not in use, hang the Gravity Feed Spray
Gun as shown in FIGURE 2.
Preparing and Operating the HVLP Gravity Spray Gun
Refer to page 5 and the Assembly Drawing on pages 10 and 11.
Note: We recommend you practice on scrap material to adjust and become
familiar with the Gun.
1. Detach the Plastic Cup (2). Insert a Filter (14) into the bottom of the Plastic Cup (2)
with the stem end pointing into the cup. This will prevent dirt and debris from entering
the HVLP Gravity Feed Gun (1).
2. Mount the Plastic Cup (2) to the HVLP Gravity Feed Gun (1). Make sure that the
Plastic Cup (2) is securely attached. Fill the cup with material that has already been
checked for viscosity (see page 6). Close to Cup (2) tightly to avoid leakage.
3. Connect the air source hose to the Air Inlet (19a). Turn on your air compressor. Do not
exceed the 50 PSI maximum.
4. Pull the Trigger (20a) slowly and move the Spray Gun in parallel strokes to the object
being painted. Keep the distance from the object being painted at 4” to 12”. This may
slightly differ depending on the flow adjustment and the material being sprayed.
5. Release the Trigger (20a) after each forward movement; pull the Trigger (20a) again on
the return movement.
6. When using a vertical pattern, move the Spray Gun in a horizontal motion; with a
horizontal pattern move the Spray Gun in a vertical motion. A round pattern requires a
greater distance from the object being painted.
7. When finished, release the Trigger (20a) and disconnect from the air source. The
Plastic Cup (2) and Spray Gun may still hold air pressure, fire the Spray Gun toward
scrap material until all of the pressure is expended. Open the Cap on the Plastic Cup
(2) before removing the Lid.
Note: Gun adjustments on page 8.
Preparing the area
1. Mask all objects you do not want sprayed.
2. Lay the appropriate size Tack Cloth (16) on the
floor, and attach Tack Cloths (16) to the surrounding
walls.
