4. Functional Description
The SATAjet 20 B spray gun is designed for the application of paints and other
sprayable media with viscosities up to 30 seconds, measured in a 4 mm vis-
cosity cup. Abrasive or acid materials as well as materials containing benzine
are not suitable for being applied with this spray gun. The atomisation air re-
quired for spraying is fed through the air inlet located on the bottom of the gun
body. When pulling the trigger until the resistance point has been reached, the
air valve is opened (pre-air control). Once the trigger is pulled completely, the
paint needle will be fully removed from the fluid tip releasing the spray material
which will be atomised by the compressed air available at the air cap.
5. Safety Instructions
Warning! Attention!
Prior to putting the spray gun into operation, read the operating instructions
which must be strictly followed completely and carefully. Afterwards, the op-
erating instructions must be kept in a safe place, accessible to every user
of the equipment.
The spray gun can only be put into operation by a trained person (profes-
sional operator). Inappropriate use, modification of any any kind of techni -
cal modification or combination with non-original parts may lead to material
damage, serious health hazards for the user, third persons or animals or
even death.
SATA cannot be held responsible for damages caused by disregarding the
operating instructions.
The applicable safety, workplace and worker health protection regulations
of the respective country must be respected by all means (e.g. the German
Rules for the Prevention of Accidents BGR 500 issued by the Central Office
of the Professional Trade Associations, etc.).
Please note:
Never point the spray gun at yourself, at other persons or animals. Solvents
and thinners can cause chemical burns. When working with the spray gun,
always limit solvents, paints or other coating media to the quantities which
are required for the job! Excessive material must be returned to the desig-
nated storage area afterwards! Prior to any repair, disconnect the spray gun
from the compressed air circuit.
Before using the spray gun, especially after it has been repaired, en-
sure that all screws and nuts are fully tightened and that neither the
gun nor the air hose are leaking.
Defective components must be either repaired or replaced, using original
spare parts only.
Always keep the spray gun away from ignition sources, such as open fire,
burning cigarettes or non-explosion-proof electronic devices, as easily flam -
mable gas mixtures are generated during the painting process.
Occupational safety regulations must be observed (e.g. wearing of PPE
etc.). Appropriate ear protection is required, as the sound level can exceed
85 dB (A) when painting with higher pressure settings.
No vibration is transmitted to the upper parts of the operator’s body during
the painting process.
Recoil forces are negligible.
The use of this product in explosion hazard areas Zone 0 is prohibited.
6. Use
6.1. General
Before putting into operation, and especially after each cleaning and any
repair work, check if all screws and nuts are tight. This applies in particular
for the material flow control screw (counter nut), the round/flat spray control
as well as the hexagonal screw on the air micrometer. For service and main-
tenance, the spray gun must be completely depressurised, i.e. disconnected
from the air supply. Failure to respect this safety instruction can lead to dam-
age and severe injuries, even death.
a) Mount the nozzle set tightly (use universal wrench for the fluid tip). Align
the air cap ensuring that the number stamped on one of the atomisation
horns is legible when looking at the spray gun from the front.
b) Blow out the air hose before attaching it to the air connection (G ¼ ext.).
The air hose must be pressure-resistant up to min. 10 bars as well as
solvent-resistant. Total electrical resistance: < 100 million Ohm.
6.2. Reduction of the Material Flow
The needle stroke controlling the material flow can be infinitely regulated with
the material flow control knob. Low needle stroke and excessive material
pressure lead to premature wear of the paint needle. In case of need, select
a smaller nozzle size.
6.3. Changing the Air Connection
The spray gun has two connection options for the air hose:
a) on the gun handle (bottom)
b) on the gun body (on the top)
If necessary, the air connection 5 has to be exchanged with the closing screw
2. The air connection and the closing screw must be tightened by hand,
without using tools.
7. Cleaning and Maintenance
a) Thoroughly rinse the material passages of the spray gun with thinner or
cleaning agent.
b) Clean the air cap with a soft brush. Do not soak the spray gun in thinner
or cleaning agent.
c) Under no circumstances try to clean clogged orifices using an unsuitable
tool, since the slightest amount of damage adversely affects the spray
pattern. Use nozzle cleaning needles.
d) 'Slightly grease moving parts with high performance grease (Art No.
48173).
Note!
Spray gun should be cleaned with solvent or cleaning agents manually or in
a conventional gun washing machine.
The procedures mentioned below will damage the spray gun and may
lead to expiry of the explosion proofness certificate as well as total
loss of any waranty:
• Immersing the paint spray gun in solvent or cleaning agents, or for a
period longer than required for the cleaning process as such
• Failure to remove the paint spray gun from the gun washing machine
after finishing the cleaning process
• Cleaning the paint spray gun by means of ultrasound cleaning sys-
tems
Warning! Attention!
When using solvents and cleaning agents based on halogenated hydrocar-
bons e.g. 1.1.1-trichlorethylene and methylene chloride, chemical reactions
can occur on the aluminium cup, gun and on galvanized components
(small quantities of water added to 1.1.1-trichlorethyelene produce hy-
drochloric acid). This can cause oxidation of the components; in extreme
cases, the reaction can be explosive.
Therefore only use solvents andcleaning agents for your paint gun which
do not contain the substances named above. You must never use acid,
alkaline solutions / Iye or stripping agents for cleaning.
7.1. Changing the Nozzle Set
When changing the nozzle size, always replace entire nozzle set (air cap,
paint nozzle and needle). Mount paint nozzle before paint needle.
7.2. Replacing the self-adjusting needle
packing
Loosen and remove material flow regulation screw and pull out paint needle.
Remove safety washer (26583) from the trigger pin (# 44677), and take out
trigger pin. Instead of paint needle, insert cylindrical end of hollow key size
3 from behind into the paint spray gun and unscrew the compression screw
