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.

3. Screw tip and guard assembly on gun. Tighten retaining nut.

ti9713a

4. Ensure spray tip arrow is pointed forward to spray position.

NOTE: If tails persist when spraying at the highest pressure, a smaller tip is needed or the material may need to be thinned.

Adjust Spray Pressure

This sprayer is set up for most airless spraying applications.

NOTE: Motor only runs when gun is triggered. Sprayer is designed to stop pumping when gun trigger is released.

• Turning knob to right (clockwise), increases pressure at gun.
