OPERATION
Fill the paint container with the material to be sprayed. DO NOT OVERFILL above MAX level indicator. Push
the fluid tube firmly into the base of the spray gun body. Screw the container onto the gun body tightly.
Place the motor unit onto a clean surface, free from any loose debris or liquids. Connect the hose to the back
of the spray gun. Uncoil the mains cable and plug in.
ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO
PREVENT PAINT CONTAMINATING THE MOTOR.
MASK ANY AREA YOU DO NOT WISH TO SPRAY.
Once you have set up ready to spray, switch on the unit. No paint will be sprayed until the trigger on the spray
gun is gently pulled. Before starting any work on spraying actual objects we suggest you spend some time
practicing on cardboard or newspaper until you have got used to how the spray gun works.
SPRAY PATTERNS
The spray gun has 3 different spray patterns – Horizontal, Vertical and Round (Fig.3)
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
The volume of paint sprayed is easily adjustable. (Fig.4)
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 anti-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 is obtained you are able to
commence spraying.
SPRAYING TECHNIQUE
1. To obtain the best results always keep your spray gun level and spray equally from side to side or up or
down 25-30cm (10”-12”) from the surface. Avoid spraying at an angle as this will lead to runs on the surface
(Fig.5a).
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.5c).
3. Do not tip the sprayer to more than 45˚angle (Fig.5c).
