2. Functional Description
The SATAjet H paint spray gun is designed for spraying paints
and lacquers as well as other media with a spraying viscosity of
up to 80 sec. in a DIN 4 mm cup. Materials that are abrasive,
acidic or contain benzine must not be used. The compressed air
supply required for the spraying is fed to the air connection that
is 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 flows then unpressurized out
of the paint nozzle due to the suction force and is simultaneously
atomized by the compressed air that flows from the air nozzle.
The lid of the cup is equipped with a drip stop that prevents the
material from escaping the vent hole.
3. Safety Instructions
Warning! Attention!
Please note:
Never point paint guns at yourself, at other persons or ani-
mals. Solvents and diluting agents can cause burns. Only
the respective quantities of solvents and paints required for
work progress may be present in the direct surroundings of
the unit and are to be returned after work to their assigned
storage rooms. Before any repair work may be carried out,
the unit must be disconnected from the compressed air
network and pressure must be released.
Before starting to use the paint gun, particularly after
repairs, ensure that screws and nuts are correctly
tightened, and check that gun and hoses do not leak.
Defect components must be replaced or repaired, use origi-
nal spare parts only.
No sources of ignition (e.g. open flames, burning cigarettes,
lamps without ex-protection etc.) may be present during
painting, as easily flammable mixtures are generated dur-
ing the painting process.
Occupational safety regulations must be applied when
painting (respiratory protection etc.). Appropriate ear pro-
tection muffs are required, as a sound level of 85 dB (A)
can be exceeded when painting under higher pressure
levels.
No vibration is transmitted to the upper parts of the opera-
tor's body during the painting process.
Recoil forces are negligible.
The use of this product in explosion hazard areas Zone 0
is prohibited.
4. Use
4.1. General
Prior to putting the unit/spray gun into operation, read the oper-
ating instructions completely and thoroughly. The stipulations
contained therein are to be respected in any case. After that, the
operating instructions are to be stored in a safe place, accessible
approx. 13.4 cfm
10 bar (145 psi)
50° C
for every user of the equipment. The unit/spray gun may only be
put into operation by persons familiar with its use (professionals).
Inappropriate use of the unit/spray gun, modification of any kind
or combination with inappropriate other parts may cause material
damage, serious hazard to the user's, other person's or animal's
health or even death. SATA shall not take any responsibility for
such damages (e.g. failure to respect the stipulations laid out in
the operating instructions). The applicable safety, workplace and
worker health protection regulations of the respective country or
area/district in which the system/the spray gun is used are to be
respected in any case (e.g. the German Rules for the Prevention
of Accidents BGR 500 (BGV D25) and BGV D24 issued by the
Central Office of the Professional Trade Associations, etc.).
a) Mount the nozzle set tightly (use universal wrench, for the
paint nozzle). Align the air nozzle so that the number stamped
into it can be read from the front the right way round.
b) Blow out the air hose before attaching it to the air connection
(G ¼ ext.). The air hose must be pressure-resistant for min.
10 bars and solvent-resistant. Total electric resistance: < 100
million Ohm, e.g. SATA air hose, Art. No. 53090.
c) The paint spray gun has been treated with an anticorrosive
agent before leaving the factory; therefore we recommend
it to be flushed out thoroughly with thinner or cleaning fluid
before use.
4.2. Setting the Spray Pattern
To adjust fan width, rotate the regulator. The spray pattern can
be altered from flat to round as required.
4.3. Reduction of the Material Volume
Needle stroke and therefore material flow is infinitely reducable
by turning the material flow control screw (unscrew counter nut,
adjust the screw and tighten the nut).
4.4. Adjusting the air volume by means of
the air micrometer
The infinitely variable air micrometer allows the spray air volume
to be adapted to suit the medium being sprayed or misted.
Note:
Maximum atomization = Air micrometer in vertical position (paral-
lel to gun body)
Minimum atomization = Air micrometer in horizontal position
(across gun body)
Attention:
While the spray gun is connected to the air supply, the air
micrometer fixing screw, Art. No. 3624, must not be removed.
When the fixing screw is removed, the spray gun must not be
put into operation.
4.5. Changing the Nozzle Set
When changing to another nozzle size, make sure that the
complete nozzle set is exchanged. These parts (consisting of air
nozzle, paint nozzle and paint needle) are always supplied in one
set. Fix paint nozzle before paint needle.
4.6. Changing the Self-Adjusting Seals
To replace paint needle packing, disassemble air cap and paint
nozzle beforehand.
a) Unscrew the packing screw (Pos. 3582) with attached socket
spanner (Pos. 3756) and take out the needle packing.
b) In order to exchange the air piston packing take off the com-
pressed air micrometer after removing the hollow screw SW2.
Pull out spring and air piston. Unscrew the pressure screw
using hollow key SW4 and replace the packing.
5. Cleaning and Maintenance
a) After use flush the gun thoroughly with thinner or cleaning
fluid.
b) Clean air nozzle with brush provided. Do not immerse the gun
in thinner or cleaning fluid.
c) Blocked orifices should never be cleaned with improper
