OPERATION

WARNING:

This is a high pressure device. To reduce the risk of injury, user must read and understand operator’s manual. To reduce the risk of injection do not point sprayer at any part of the body, persons, or unit itself. In case of skin injection, seek medical attention immediately. Failure to heed this may cause serious personal injury.

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.

•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® Revolutionary White Formula Paint Thinner (for oil-based paints or varnish).
