Operating Instructions
Preparation
To obtain the best results, it is important that you prepare the surface to be sprayed and thin the paint to the cor-
rect viscosity before you start work. Always ensure that the surface to be sprayed is free from dust, dirt, grease
and other foreign bodies. Always mask the areas around the areas to be sprayed using good quality masking
tape. The paint to be sprayed should be suited to the task and compatible with your spraygun. There should be
no lumps or other particles. Make sure that you have a properly working strainer. Many substances can be
sprayed with this gun but it is important that you check with your paint supplier before purchasing your paint. It is
very important that you check the panel for signs of silicone contamination befo e starting work.
Thinning
Most paints are supplied ready for the type of application and applying technique but may have to be thinned for
use with your spraygun. Always follow the paint manufactures advice on thinning paint. The viscosity cup sup-
plied will help you determine the correct viscosity of the paint to be used. To measure the viscosity if the paint fill
the cup to the brim and measure the length of time it take to empty. The table below shows the recommended
times for different materials. Please note that this is intended as a guide only and you should advice from your
paint supplier.
Plastic & atex 24-28secs Water based Paint 20-25secs
Primers 24-28secs Varnishes 20-25secs
Oil based paints 18-22secs Enamel paints 18-22secs
Aluminium paints 22-25secs Car underseal 25-35secs
Wood sealers 28-35secs Wood preservatives Not required
Wood stains Not required
If the paint takes longer than the recommended time to empty, further thinning is required. Mix a small quantity of
the appropriate thinner and use the viscosity cup again until the required figure is achieved. Some paints contain
lumps and particles and these should be strained before use.
Spraying
Fill the paint cup with the appropriately thinned paint and screw onto the gun. Connect the air hose and then plug
in the mains supply and switch on. It is recommended that you use a test card or scrap panel to make sure that

the paint is correct. This also aids comparison with existing paint work.
Applying pressure to the trigger will start the spraying. To obtain a greater flow of paint, turn the fluid output con-
trol anti-clockwise. Turning it clockwise will reduce the paint flow. Be aware that adjusting this control also
altered the spray pattern. A poor pattern will concentrate the spray towards the centre of the pattern, giving a
lumpy blotchy finish. A good pattern will evenly distribute the paint throughout the pattern.
To get best results, keep your spraygun level and at 90oto the surface at all times (see Fig.1). Keep the nozzle
200-300mm from the surface and spray evenly from side to side or up and down. Spraying at an angle will lead
to paint runs. Use smooth, even strokes. When spraygun large areas, use a criss-cross pattern as shown in Fig.
2.
Never start or stop the gun whilst it is aimed at the workpiece. Too slow a pass will give a thin and patchy coat
whilst too slow a pass will result in a heavy coat. Apply one coat at a time and observe manufacturers drying
times before applying the next coat or finishing/polishing. Do not tip the gun more that 45o.
