1.2 Short description
The spray gun is intended for surface
coating without compressed air. It is suitable
for Airless Applications in the high pressure
area. The material to be atomized is fed
through high pressure lines and atomized
with a pressure of up to 300 bar. The spray
gun is hand-held.
Use a nozzle with a suitable diameter,
depending on the requirement. If there is a
blockage, you can rotate and flush the
nozzle through without disassembly.
The following factors influence the spray jet
and therefore the result
Material pressure
The higher the material pressure, the
higher the material flow and thus the finer
the atomization. The lower the material
pressure, the higher is the efficiency and
the smaller is the overspray generated.
Nozzle
The larger the nozzle, the more material
comes out. The greater the angle, the
wider is the spray pattern.

6 Operation
6.1 Safety recommendations
WARNING!
Danger of explosion due to chemical
reactions
Material, halogenated hydrocarbon-based
rinsing agent or cleaning agent can chemi-
cally react with aluminum components of
the product. Chemical reactions can
cause explosions. Serious injuries and
death can be the consequence.
– Only use rinsing agents and cleaning
agents that do not contain any halo-
genated hydrocarbons.
Operation
05/2018 EcoGun AL MAN 300 - MSG00016EN 9/44

WARNING!
Danger of fire and explosion due to
explosive gas-air mixture
If you spray in a closed container during a
purging sequence, an explosive gas-air
mixture can form inside the container.
Serious injuries and death can be the con-
sequence.
– Do not spray into a closed container.
WARNING!
Danger of fire and explosion
Flammable coating materials and their
detergents and cleaning agents can cause
a fire or an explosion.
– Ensure that the flashpoint of the fluid is
at least 15 K above the ambient tem-
perature.
– Note explosion group of the fluid.
–Follow safety data sheets.
– Ensure that forced ventilation and fire
protection equipment are in operation.
– Do not use sources of ignition and
open light.
– Do not smoke.
WARNING!
Danger to health from harmful or irri-
tant substances
Contact with hazardous liquids or vapors,
can result in serious injury or death.
– Ensure that the forced ventilation is
operational.
– Follow safety data sheets.
–Wear specified protective clothing.
WARNING!
Material Escaping Under Pressure
If material escapes with high pressure, it
can penetrate the body. Even if the injury
looks like a harmless cut wound, the pen-
etrating material leads to amputation,
serious injuries can cause death.
– Use hoses that can withstand at least 4
times the operating pressure.
– Do not try to seal leakages using body
parts, gloves or towels.
–If there are injuries, seek medical
attention immediately.
Before working on the product:
– Disconnect the system, in which the
product is installed, from material
supply system.
– Secure the system against reconnec-
tion.
– Respect the maximum allowable oper-
ating pressure of the product.
– Relieve the lines.
NOTICE!
Material damage due to dried material
residues
If material residues dry in the product, that
can harm components.
– Rinse product immediately after each
use.
6.2 Checks
Material hose is in order.
Material connection is in order.

6.4 Painting
NOTICE!
Paint damages due to wrong guiding of
the spray gun
If you guide the spray gun at an angle or
in an arc, the spray jet meets the surface
to be painted unevenly. Different dis-
tances arise in the spray jet between the
spray gun and surfaces to paint. This
results in uneven material coat thickness
and painting defects.
If the distance to the surface to be painted
is too short, too much material reaches
the surface. Drops and runs arise on the
surface.
If the distance to the surface to be painted
is too much, too little material reaches the
surface. Spray mist is produced. Dry
atomization gives rise to a raw and matter
material layer.
– Guide the spray gun in a straight line at
a 90° angle at a constant distance of
25 to max. 30 cm from the surface to
be painted.
– Guide spray gun with a constant
speed.
–Ensure that correct material pressure
according to the material consistency
is selected.
– Ensure that correct nozzle according to
the material consistency is selected.

wise to increase the covering
capacity and coat thickness.
Switching between horizontal and
vertical spraying stripes (Fig. 8)
yields a uniform and closed spray
pattern.

from left to right.
4. Apply material alternately vertically from
top to bottom.
5. Release trigger (1, Fig. 6) after ending

WARNING!
Risk of injury from unsuitable replace-
ment parts in explosive areas.
Replacement parts not compliant with the
specifications of the ATEX guidelines can
cause explosions in an explosive atmos-
phere. Serious injuries and death can be
the consequence.
– Use exclusively original replacement
parts.
CAUTION!
Risk of injury due to spring tension

spring tension. If you remove the end cap,
the spring tension could cause the end
cap to jump out unexpectedly and cause
light injuries.
– Removing and installing end cap
NOTICE!
Property damage due to improper
replacement of needle and nozzle seal
seat
If you only replace the needle or only the
nozzle seal seat, it could damage spray
gun components. This can compromise
the tightness of the spray gun. The spray
pattern deteriorates.
– Always replace nozzle seal seat and
needle at the same time.
