• We recommend you wear protective clothing. • Stir the paint well using a mixer where possible. • Make sure there are no solid particles in the paint. • Many products can be sprayed without being thinned. However, if the application is not good, thin the product progressively in stages of 5%. • Most paints can be sprayed by being thinned just a little, e.g. by 5% or 10%. • Some thick paints such as outer wall paints and certain undercoats will need to be thinned by 20% or 25%. • Use water to thin a water-based product. • Use appropriate thinner to thin solvent-based products. • Certain manufacturers will indicate on the can whether a specific thinner is to be used. • Certain paint manufacturers have specific paints available for HVLP application. Dip the viscosity cup into the material and fill up. Check the guide below for the viscosity rating for your machines. Time how long it takes for the paint to stop being a continuous flow, from the bottom of the cup (Fig.4). If the paint requires thinning, start with a 5% dilution of the paint. To do this, part fill a container with one litre of paint. The viscosity cup supplied with the unit holds 1/10 of a litre, block the hole in the viscosity cup and fill up with the required thinner. Add the thinner to the paint and stir, measure the viscosity. If the paint requires further thinning, dilute the paint by another 5% (5% will be equal to half a viscosity cup) with the required thinner and measure the viscosity, if the paint is not at its recommended viscosity, repeat the above step. Viscosity Ratings The spray station 2900/3500 has a viscosity rating of 160 seconds. If the paint has emptied the viscosity cup in less than 160 seconds then you will not need to thin your paint or material. If it is above this then thinning will be required. The spray station 3900 has a viscosity rating of 180 seconds. If the paint has emptied the viscosity cup in less than 180 seconds then you will not need to thin your paint or material. If it is above this then thinning will be required. The spray pack has a viscosity rating of 70 seconds. If the paint has emptied the viscosity cup in less than 70 seconds then you will not need to thin your paint or material. If it is above this then thinning will be required. The above ratings are a guide, dependent on paint formulation further dilution may be required in increments of 5%. 12 3 1 2 4 5 6 7 8 9 10 11 DILUTION Fig.4 Type of paint Cleaning Water based paint Clean with water Oiled based paint Clean with appropriate thinner e.g. White Spirit CLEANING INSTRUCTIONS SPRAY GUN HINT: Before removing or re-inserting the Needle and Fluid Tip ensure the Spray Gun has been flushed through with water or the appropriate thinner so the inner tube is clean. HINT: When done immediately the cleaning operation can take you less than 5 minutes. If taking a break, leave the Spray Gun in a closed plastic bag to prevent the paint from drying. • Remove the Paint Container (12). • Pour any leftover paint into its container so that it can be used for the future. Pull the Trigger to allow paint to run out of the Pick-up Tube (11). • Pour a quantity of the respective thinner into container, shake the Spray Gun lightly, reassemble the Spray Gun, then spray this liquid though the Spray Gun. Repeat this until the thinner being sprayed is coming through with no traces of paint. • Clean any traces of paint off the outside of the Spray Gun. • Clean the P aint Container Seal (10). FLUID TIP AND NEEDLE • Unscrew Air Cap Ring (2). • Remove the Air Cap (3). • Remove the Spray Direction Plate (4). • It is recommended that you push the Trigger forward to help release the Fluid Tip (5). • Using the Needle and Fluid Tip Tool - pincer end A (1) remove the Fluid Tip (5). • Insert the Needle and Fluid Tip end B (1) into the inner tube and unscrew the Needle anticlockwise, then pull to release the Needle. • Place all of these items into a container and clean, then using a brush and the respective thinners. • Clean the inside of the body of the Spray Gun. • Thoroughly dry all parts before reassembling. • Reassemble parts in reverse order. • Ensure the Air Cap Ring (2) is fully tightened and the Fluid Tip is pushed into place so that the Spray Gun Needle will shut off. NB: Ensure the Spray Direction Plate is free to move. If necessary loosen the Air Cap Ring (2) slightly. • NEVER DISPOSE OF PAINTS OR SOLVENTS DOWN THE DRAIN. ALWAYS USE YOUR LOCAL WASTE COLLECTION SITE. • The motor unit itself does not require any specific maintenance apart from checking that the filter is not clogged up (the filter can be removed and washed). The filter can be found in the base of the motor unit. Important: Each Fluid Needle is manufactured to fit the size of the corresponding Fluid Tip. Do not try to fit a 2.0 mm Fluid Needle to a 3.0 mm Fluid Tip. 5 Fig.8 Fig.9 HINT: HVLP technology produces warm air through the Air Cap allowing the paint to dry quicker which can enhance the final effect.
