Most paints and solvents contain chemicals that are harmful to the environment.
Dispose of paints, solvents and their containers in accordance with local
regulations. Keep paint and solvents away from children.
Never pour any type of paint away down a drain.
(1): The flash point is the temperature at which an ignition source 1 cm from the surface of the liquid will
cause ignition.

6. Preparation
Liquids
Paints usually need to be diluted for use with the spray gun. Before using the spray gun, determine the
viscosity of the liquid. Use the guidelines in the table below to obtain a sprayable solution.
1. Stir the liquid thoroughly before measuring.
2. Make sure the viscosity cup [A] is clean and fill it to the top with liquid.
3. Measure the depletion time of the cup. Refer to the table below for an overview of recommended
depletion times (in seconds) for various types of paint.
Spray liquid Depletion time Spray liquid Depletion time
thinner-soluble primers 25-40 s wood preservatives, strippers, oils use undiluted
thinner-soluble varnishes 15-40 s disinfectants, plant protectors use undiluted
water-soluble primers 25-40 s automobile spray paint 20-35 s
water-soluble varnishes 20-35 s
4. If the measured depletion time is higher than indicated in the table, the paint must be diluted with a
suitable thinner. Mix well and measure the viscosity again. Repeat this step until the depletion time
is within the limits as shown in the table above.
