Spraying Techniques

Preventing Excessive Tip Wear

•Spray should be atomized (evenly distributed, no gaps at edges). Start at low pressure set- ting, 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 16.

If tails persist when spraying at the highest pressure, a smaller tip is needed or the

material may need to be thinned.

Getting Started

Unclogging Spray Tip

To avoid fluid splashback:

•Tip must be pushed all the way into guard.

•Never pull gun trigger when arrow-shaped han- dle is between SPRAY and UNCLOG positions.

1.To UNCLOG tip obstruction, engage trigger lock.

3.Aim gun at piece of scrap or cardboard.

4.Unlock trigger lock. Pull trigger to clear clog.
