Preparing and Operating Touch-up Gun
Refer to page 5 and the Assembly Drawing on pages 10 and 12.
Note: We recommend you practice on scrap material to adjust and become
familiar with the Gun.
1. Detach the Plastic Cup (6). Fill the cup with material that has already been checked for
viscosity (see page 6). Close the Plastic Cup (6) tightly to avoid leakage.
2. Mount the Plastic Cup (6) to the Touch-up Gun (5). Make sure that the Plastic Cup (6)
is securely attached.
3. Connect the air source hose to the Air Inlet (14b). Turn on your air compressor. Do not
exceed the 50 PSI maximum.
4. Press the Trigger (5b) 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 (5b) after each forward movement; press the Trigger (5b) again on
the return movement.
6. When using a vertical pattern, move the Spray Gun in a horizontal motion; with a hori-
zontal 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 (5b) and disconnect from the air source. As the
Plastic Cup (6) and Spray Gun may still hold air pressure, fire the Spray Gun toward
scrap material until all of the pressure is expended.
