Setup Install Tip and Guard on Gun Spraying Techniques Preventing Excessive Tip Wear • Spray should be atomized (evenly distributed, no gaps at edges). Start at low pressure setting, increase pressure a little at a time until you see a good spray pattern, without tails. • Spray at lowest pressure that atomizes paint. • If maximum sprayer pressure is not enough for a good spray pattern, tip is too worn. See Reversible Spray Tip Selection Chart, page 15. 1. Engage trigger lock. ti8908a 2.
Setup Unclogging Spray Tip 4. Unlock trigger lock. Pull trigger to clear clog. To avoid fluid splashback: • Never pull gun trigger when arrow-shaped handle is between SPRAY and UNCLOG positions. • Tip must be pushed all the way into guard. 1. To UNCLOG tip obstruction, engage trigger lock. ti8909a 5. When obstruction is cleared, engage trigger lock and rotate arrow-shaped handle back to SPRAY position.
Setup Tip Selection Selecting Tip Hole Size Tips come in a variety of hole sizes for spraying a range of fluids. Your sprayer includes an 0.015 in (0.38 mm) tip for use in most spraying applications. Use the following table to determine the range of recommended tip hole sizes for each fluid type. If you need a tip other than the one supplied, see the Reversible Tip Selection Chart on page 15. • Maximum tip hole sizes supported by the sprayer: – LTS 15: 0.015 in. (0.38 mm) – LTS 17: 0.017 in.
