Operating Instructions SATAgraph 1
4.1 Air pressure
The operating pressure is approx. 1 - 3 bars. The higher the gun inlet pressure, the better the
atomization and the more difficult the handling. When the pressure is too low, no optimum paint
atomization is achieved, depending on the paint material. If the compressor allows adjustment of
the output pressure, different pressures may be tried until the desired results are achieved.
4.2 Paint material
When using solvent-based paints and lacquers it must be ensured to thin them down until they
reach the consistency of milk. Otherwise the paints and lacquers are too thick to be „brushed“,
and it is not possible to achieve a fine atomization with sufficient material flow. Waterborne paints
and lacquers, too, must be thinned sufficiently.
Modern airbrush colors and lacquers are offered ready for spraying. Please respect the material
manufacturers‘ stipulations.
4.3 Correct adjustment of the gun inlet pressure
Adjust required operating pressure (1 - 3 bars) at the pressure regulation unit
of the compressor, as far as available. This unit is integrated directly at the
compressor air outlet, or into an air supply pipe. The pressure regulator can
also be a compressed air filter unit with pressure regulator, e.g. „SATA 0/444“,
connected in between. By pushing down the trigger (1) the compressed air
volume can be adjusted.
4.4 Material volume
By pulling the trigger (1), the material flow can be adjusted.
Adjusting the
needle stroke defined by the user:
Unscrew end piece (10), loosen paint
needle quick tension (9). Adjust trigger (1) bedstop according to requirements
(hold in position), push paint needle under slight pressure towards the front into
the paint nozzle (5) until bedstop and then fix paint needle by means of the
paint needle tension (9). Connect end piece (10).

4.5 Nozzle set replacement (without tool)
The nozzle set consists of air cap (4), paint nozzle with „O“ ring (5) and paint
needle (6). For dismantling the nozzle set the end piece (10) must be unscre-
wed completely from the gun body (2).
4. Putting into Operation
Before putting into operation, and especially after each cleaning and any repair work, check to see
that all screws and nuts are tight. The paint spray gun has been treated with an anticorrosive agent
before leaving the factory and must therefore be flushed out thoroughly with thinner before. For
servicing/repair work of any kind, the system must be devoid of pressure, i.e. disconnected from
the air supply. Failure to respect this safety warning may result in damage and injuries, even death
at worst. SATA does not take any responsibility for possible results of such failure.
