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)
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.
*Gun ‘A’ does not need aircap ring released to turn cap.

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 o 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.

SPRAY PATTERN
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.
