Spraying

Start

Notice:

Spray performance will depend upon a number of factors:

material thickness, spray pattern selected, material volume,

and air pressure. With any type of air-assisted spraying,

desired spray results will be achieved through some trial and

error while adjusting some or all of these variables.

Review these pages to learn about the spray controls and how

they can be used to acheive the desired spray results.

Controls

Air Pressure Control Dial

The air pressure control dial adjusts the level of air pressure

produced by the turbine. The air pressure control dial is factory-

set at maximum out of the box.

• A high air pressure level will result in a smoother nish.

• Lowering the air pressure will result in larger drops of

material being sprayed from the gun, and will create a

slightly rougher nish.

Tip: The thicker the material you are spraying, the higher the

turbine pressure you will need.

Tip: For ne-nish work with thinner materials, you may want

to decrease the air pressure. Spraying a thinner material at high

air pressure will result in more overspray. Overspray is sprayed

material that does not stick to the spray surface and bounces

back.

Material Flow Adjustment

The material ow adjustment controls the amount of spray

material that is sprayed from the spray gun.

• For thicker materials, it is recommended that you

start with the highest material ow setting and then

gradually decrease the ow to suit your particular

spraying needs.

• For thinner materials, it is recommended that you start

with a low material ow setting, and then gradually

increase the ow to suit your particular spraying

needs.

• The higher the ow setting, the quicker you will have

to work in order to avoid drips and sags in your spray

pattern.

Set the material volume by turning the knob on the trigger

of the spray gun.

Tip: Spraying with the knob set too high will result in a

spray pattern that runs and sags (too much material).

Tip: Spraying with the regulator set too low will result in a

spray pattern that does not cover (not enough material).

Adjust Spray Width - white gun only

The adjustment ring on the white spray gun determines the

width of the spray pattern.

Adjustment ring

Wide

pattern



For coating large surfaces



Use higher air pressure



Use higher material volume

Narrow

(round)

pattern



For coating smaller areas,

corners and edges



Use lower air pressure



Use lower material volume

Adjust Spray Shape - both guns

The spray pattern shape is adjusted by turning the

ears of the air cap to either the vertical, horizontal, or

diagonal positions. The positions of the air cap and the

corresponding spray pattern shapes are illustrated below.

Test each pattern and use whichever pattern is suitable for

your application.

NEVER trigger the gun while adjusting the

ears on the air cap. NEVER point the spray gun

at any part of the body.

*Note: The air cap can be set diagonally on the yellow spray

gun only. To achieve a round pattern with the white spray

gun, see “Adjusting the Spray Width”, previous column.

Horizontal

pattern



Use ‘up and down’ spraying

motion

Vertical

pattern



Use ‘side to side’ spraying

motion

Round

pattern



Use ‘up and down’ or ‘side to

side’ spraying motion



Use lower air pressure /

material volume



For coating smaller areas,

corners and edges
