Flushing the airless paint sprayer
Before using the paint sprayer for the first time or before beginning a new project or changing colors, it is important to thoroughly flush the paint sprayer of any storage fluid, previous cleaning fluid, or material left in the system. Follow instructions for Cleaning the Airless Paint Sprayer before beginning any project.

Selecting a spray tip
See Figure 11.
Spray tips come in a variety of hole sizes and fan widths.
Your unit includes two reversible spray tips with a hole size of .010 in. and .019 in. that will work for a wide variety of applications. The 310 spray tip has a fan width of
HOLE SIZE: Spray tip hole size determines the flow rate, which is the amount of paint that is discharged from sprayer.
A larger hole size is best for thicker materials. A smaller hole size is best for thinner materials.
FAN SIZE: Fan width determines the size of the spray pattern when sprayer is held approximately 12 in. from surface to be painted.
A narrow fan width will provide thicker coverage of material and is better suited for small, tight areas. A wide fan width will give thinner coverage of material and provide better coverage on large, broad areas.
Spray tip NUMBERS: When selecting a spray tip, the last three numbers of the spray tip number contain information on hole size and fan width.
For example, if the spray tip number is 1415, the 4, when doubled is the approximate fan width of paint when applied 12 inches from surface. The last two numbers, 15, refer to the hole size in inches. In this case .015 in.

Spray tip WEAR: It is important to replace spray tips when they become worn. A worn spray tip will cause uneven application and finish of material. Over time the spray tip hole size increases and the width of the fan spray decreases.
When using latex paint, spray tips need to be replaced between 15 and 40 gallons of use. For oil based materials, replace spray tips after 35 to 60 gallons of use.
To increase the life of your spray tips, use the lowest pressure setting needed to apply an even coating of material.
