PAINTING TIPS
See Figures 13 - 14.
 Practice spraying on a piece of scrap material to test your
spray pattern before beginning. If you cannot get a good
spray pattern, see Troubleshooting section.
 To create an even coating over the entire surface:
• Keep the pistol-grip sprayer an even distance from the
area being sprayed, about 12 inches from the nozzle
tip guard to the surface being sprayed.
• Operate the pistol-grip sprayer in straight horizontal strokes. Do not hold the sprayer at an angle. This will
result in uneven coverage.
• Depress the trigger to start the spray at the beginning
of the stroke and release the trigger as you end the
stroke. To prevent material build-up, do not keep the
trigger depressed as you proceed to the next stroke.
OPERATION
• Make one pass for each stroke. Overlap strokes in
halves for full coverage.
 When finished, return any unused paint or stain to its
original container and thoroughly clean the sprayer.
WARNING:
To reduce the risk of fire or explosion: Do not use with
flammable liquids (i.e., paint stripper, paint remover,
brush cleaner, mineral spirits, lacquer thinner, turpentine,
acetone, gasoline, kerosene, etc.). Use only water (for
water-based paints) or Klean Strip
Formula Paint Thinner (for oil-based paints or varnish).
