1. Putting into operation
Before putting into operation and especially after any repair work, check to see that all nuts and
bolts are tight. Always disconnect the unit from the air supply before carrying out any repair
work.
a) Mount the nozzle set tightly 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 (1/4"). (Air hose
pressure-resistant up to min.10 bar and solvent-resistant. Total electric resistance: less
than100 million Ohm;)
c) The paint spray gun has been treated with an anticorrosive agent before leaving the factory
and must therefore go flush out thoroughly with thinner before use.
2. Adjusting the volume of air using the compressed-air micrometer
The air supply can be regulated extremely fine to suit all operational conditions. Micrometer in
vertical position (parallel to gun body)=maximum atomization. Micrometer in horizontal position
(across gun body)=minimum atomization(for blending, etc.) During operation, never remove
hollow by using the small hollow key in order to remove the micrometer.
3 Reduction of the material volume
The volume of material flowing from the nozzle and thus the needle stroke can be reduced
steplessly by screwing in the material-volume regulation screw.
4. Changing the nozzle set
Always change the complete nozzle set whenever changing nozzle size. These components,
that consist of air cap, fluid nozzle and paint needle are supplied as a complete set. Insert paint
nozzle before paint needle.
5. Exchanging the air piston and air piston packing
To replace the air piston remove the hollow screw and detach the air micrometer. Pull out
spring and air piston. Exchange the air piston. Unscrew stuffing box screw and remove the old
packing. Now insert new Packing with flat end first and gently tighten stuffing box screw
towards packing.
6. Cleaning and maintenance
a) Flush the material-conveying parts of the gun thoroughly with thinner.
b) Clean the air nozzle with a paint brush or brush. Do not immerse the nozzle in thinner.
c) Under no circumstances try to clean clogged orifices using an unsuitable tool, since the
slightest amount of damage.
