►
Never point the spray gun at persons or animals - risk of injury.
►
Follow the processing and safety notes of the spraying material and cleaning
agent manufacturers. In particular, aggressive and caustic materials can cause
damage to health.
►
Particle-carrying discharged air must be kept away from the working area and
operating personnel. However, respiratory protection and work clothing should
always be worn in accordance with regulations when processing materials with
the spray gun. Airborne particles can damage your health.
►
Wear eye protection during painting and cleaning.
►
Wear hearing protection in the working area of the spray gun. The noise level
generated by the spray gun is approx. 83 dB (A).
►
Always make sure that all nuts and bolts have been tightened when starting the
unit, especially after assembly and maintenance work.
►
Use only original spare parts, since only then SIMALFA can guarantee the safe
and fault-free functioning of these parts.
►
Always depressurize the spray gun after work is completed.
►
The maximum pressure values from the technical data must be observed.
Please contact ALFA Klebstoffe AG, for further information regarding the safe use of
the spray gun and the materials used in them.

Note
Please refer to the explosion drawing (page 2) in these operating instructions to
perform the work steps listed.
4.1
Spray Pattern Test
A spray pattern test should always be generated when:
•
the spray gun is used for the first time
•
the spray material has been replaced
•
the gun has been disassembled for maintenance or repair
The spray pattern can be applied to a sample work piece, sheet metal, cardboard or
paper.
1. Start operation of the spray gun to generate a spray pattern test (see
4
Connecting supply lines and
Operation
.
2. Check the spraying pattern trial and change the settings on the spray gun, as
necessary (see
4.2 Changing the spray pattern
).
4.2
Changing the spray pattern
You can change the spray pattern on the G9 2K by making the following settings:

Converting / repairing the spray gun
The air cap / material nozzle / needle combination matching the spraying material
represents an interactively tuned unit - the nozzle set. Always replace the entire
nozzle insert to maintain the desired spray pattern quality.
Note
All movable and sliding parts must be greased with gun grease before installation
in the gun body

The gun is now ready to be operated.
4. To allow the air in the material
hose to escape, operate the trigger
until a uniform material jet (compo-
nent A) and activator (component
B) exit from the nozzle.
3. Set the desired material pressure
and air pressure on your supply
unit.
2. Connect the material supply hoses
to the material connections (com-
ponent A/ component B) of the
spray gun.
1. Connect the compressed air hose
to the air connection of the spray
gun.
Adjusting the material flow volume
The material volume can be regulated by turning the adjusting
screw (item 9) in or out. The material volume is increased by
turning it to the left (unscrewing) and reduced by turning it to the
right (screwing down).
Regulating the material pressure
You can adjust the material pressure only on the pump or the
pressure tank. Please follow the directions and safety instructions
of the manufacturer.
