2. Functional Description

2.1 General Points

The SATAjet 3000 B HVLP paint spray gun is designed for spraying paints and laquers as well as
other media (Nozzle size depends on spray viscosity). Materials that are abrasive, acidic or contain
benzine must not be used. The compressed air supply required for spraying is fed to the air connec-
tion screwed into the gun grip. Squeezing the trigger as far as the first pressure point opens the air
valve (pre-air control). When the trigger is squeezed further, the paint needle is pulled out of the paint
nozzle. The spraying medium then flows unpressurized out of the paint nozzle due to gravity and is
simultaneously atomized by the compressed air that flows the air nozzle.
The cup lid is equipped with a drip stop that prevents the material from escaping from the vent hole.
2.2 Electronic pressure indication
The electronic pressure indication, integrated into the spray gun handle, indicates after operation of
the trigger and from 0.2 bar (3 psi) on, the spray gun inside pressure regulated onto the air com-
pressed micrometer with a precision of ± 0.05 bar (± 1 psi). Maximum indication value is 99 psi or
9.9 bars. When the gun inlet is not pressurized, the measuring device remains shut off in order to
prolong battery life. Battery life time is 1-3 years, depending on time of use. The measuring device is
hermetically protected against all external influences (maximum temperature 60° C/140° F). If there
is no indication visible above 0.2 bar (3 psi), unscrew the lid of the battery compartment by using a
coin (It is only allowed to open the battery compartment in non-hazardous areas) and replace the
battery, including battery compartment cover with sealing (Order No. 133884). Open the battery
case for changing of battery only! Everytime you open the battery case, the sealing cap must
be replaced by the new battery case sealing cap included in set 133884. The use of already
used battery case sealing caps leads to loss of warranty! After that, close the compartment and
make sure it is tight (the battery compartment seal must not be damaged and must be inserted cor-
rectly into the groove of the closing screw). (Battery manufactured by M/S Renata, type CR 1632).
Always replace battery including complete battery compartment cover with seal. Work process must
be stopped immediately if the pressure measuring device, the screen, the glass pane etc. suffer
damage. Exclusively SATA technicians are authorized to effect repairs with the pressure measuring
device. Any intervention with the measuring chamber, by removing the front plate, is dangerous, will
subsequently imply loss of the certificate of explosion-proofness, of the warranty and will destroy the
pressure measuring device.
2.3 ATEX, FM Global, CSA (explosion safety)
The digital pressure measuring device have been submitted to a design examination and is develo-
ped, constructed and manufactured in accordance with the EC guideline 94/9 EG.
It were classified according to
and may beused in the explosion hazard zones 1 and 2 up to 60° C .
