2. Functional Description

2.1 General Points

The SATAjet RP 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 con-
tain benzine must not be used. The compressed air supply required for spraying is fed to the
air connection 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 compressed micrometer with a precision of ± 0.2 bar (2 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. 14985).
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 14985. 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 correctly into the groove of the closing screw).
(Battery manufactured by M/S Renata, type 357). Always replace battery including complete
battery compartment cover. Work process must be stopped immediately if the pressure
measuring device, the screen, the glass pane etc. suffer damage. Exclusively SATA techni-
cians are authorized to effect repairs with the pressure measuring device.
Any intervention with the measuring chamber, by removing the front plate, is dan-
gerous, will subsequently imply loss of the certificate of explosion-proofness, of the
warranty and will destroy the pressure measuring device.
