SPRAY PATTERNS

The spray applicator has 3 different spray patterns – Horizontal, Vertical and Round (Fig.4)

The horizontal and vertical are recommended for large surfaces. Vertical JetHorizontal JetRound Jet The round spray is used for small objects or for areas - such as

corners – that are difficult to reach.

To adjust the spray pattern, loosen the Air Cap Ring (1), adjust the position of the Air Cap (2) to obtain either a vertical, horizontal or round pattern then re-tighten the aircap ring.

PAINT VOLUME

The volume of paint sprayed is easily adjustable. (Fig.5(a))

Completely close Fluid Adjusting Screw (8) by turning this clockwise as far as it will go. Whilst pulling the trigger, begin turning the adjustment screw counter-clockwise until the volume of paint you require is obtained.

If the paint spray is too wide or contains too much paint turn the Fluid Adjusting Screw clockwise again. Once the correct spray pattern & paint volume is obtained, you are

ready to begin spraying.

SPRAYING

SPRAYING TECHNIQUE

1.To obtain the best results always keep your spray applicator level and spray equally from side to side

or up or down 10”-12” (25-30cm) from the surface. Avoid spraying at an angle as this will lead to runs on the surface (Fig.6a).

2.Let your arm control the left to right movement rather than your wrist as this will aid even paint distribution over the whole area (Fig.6b).

3.Do not tip the sprayer to more than 45˚angle (Fig.6c).

HELPFUL HINTS

1.Evenly control the speed of movement of the spray applicator. A fast speed will give a thin coat and a slow speed will give a thick coat.

2.Only apply one coat at a time. If a further coat is required follow the paint manufacturer’s instructions for drying times.

3.If spraying small areas or objects keep the output setting low as this will avoid excessive use of paints and will minimise overspray.

4.When spraying large areas or objects, it is best to use a criss-cross pattern, either from left to right then up or down or vice-versa. This will ensure maximum coverage (Fig.7).

5.Avoid stopping and starting when spraying as this can lead to too much or not enough material on a surface.

6.To ensure edges are covered, commence spraying just to the side of area being sprayed.

7.CLEAN SPRAYER AFTER EVERY USE (SEE CLEANING INSTRUCTIONS)

Let go of the trigger at the end of each spray movement to avoid excessive paint and drips
