5. Perform test runs on some test pieces. This way you can determine the optimum amount
of paint and the different paint jet adjustments.
Hints for Operation
▪
Note the parameters given by the manufacturer of the coating materials to be used. Pour
the material to be processed in the paint cup (1b) and carefully close the cup with the lid.
Pay attention that the hole in the lid is free at all times.
Pay attention to the air hose when painting.
Hold the hose firmly with one hand while operating the spray gun with the other hand. The
hose must not be bent. Do not step on it, as this will lead to formation of droplets.
▪
The movement speed of the spray gun depends on the setting of the paint flow regulator
(1c). With little paint, move the spray gun slowly. With plenty of paint move it faster. Do not
spray in an arc on the surface and do not interrupt spraying as this will lead to uneven or
too little paint distribution onto the surface. The general recommended spraying distance is
about 20 cm.
▪
If the finish is too wet, reduce the amount of paint with the paint flow regulator (1c).
▪
Always keep the spray gun in a constant distance to the surface to be sprayed. Move the
spray gun evenly and in parallel lanes from one side to the other.
▪
Start spraying openings and corners of the object. If necessary, take a short break after
each spraying process, so the solvents may start flashing off. Each lane should overlap to
at least 50 %. Move the gun evenly and always horizontal to the object. Always work from
top to bottom. Move the spray gun over the edges of the object so that the edges get enough
paint.
▪
If you do not use the spray gun for a short time, hang it on the suspension eye Turn off the
air supply and release the pressure.
▪
Check the paintwork on all sides, before cleaning the spray gun. After work empty the paint
container into an appropriate bin. Properly dispose of coating material that is no longer
needed.
▪
Recently treated surfaces must not be exposed to direct sunlight, to very high or low
temperatures, wind, dust, water or rain.
Cleaning
When using water-soluble coating material, simply clean all parts of the air spray gun
thoroughly with water.
Intensive Cleaning
▪
Please note that disassembling and intensive cleaning of the
spray gun are inevitable, as otherwise it can lead to debris
and to a bad spray result, if lacquer and priming coats are
used as coating material.
▪
Clean the spray gun and the paint container after each use
with appropriate paint thinners or cleaning agents. Empty the
contents. Fill a little paint thinner into the paint container and
rinse it. Empty the paint container and repeat the process
with clean paint thinner. Spray the clean paint thinner in short
strokes.
▪
During cleaning please always wear a respirator mask and
solvent-resistant gloves! Also wear eye protection, as
splashes of solvents can cause injuries of your eyes.
▪
Never put the paint spray gun into solvents for a longer
period of time or overnight.
▪
Never use hard or sharp objects to remove paint residues. The nozzle must always be kept
clean. Debris of dried paint can distort the paint jet and damage the spray gun.
