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

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.

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

Fig.5(a) shows the Air Volume Control Valve which regulates the flow of air to the gun.

When the Valve is fully open you will achieve maximum coverage. To achieve this

rotate ‘fully’ anti-clockwise. This is to be used in conjunction with the Fluid Adjusting

Screw for best results.

The volume of paint sprayed is easily adjustable (Fig.5b). Completely close Fluid

Adjusting Screw (B) 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 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 when the motor is

switched OFF. You can tip the spray gun at more of an angle when

spraying celings and decking etc, providing that the motor is

switched ON.
