Troubleshooting
In all cases of malfunction, please first check whether there is sufficient com-
pressed air available, whether the spray material can still be processed,
whether the expiry date has passed or whether the material has dried out.
•
Gun sprays messy
Possible cause: Working pressure too low, nozzles are dirty.
Solution: Increase working pressure, clean nozzles.
•
Gun does not spray any material
Possible cause: The riser pipe and/or nozzles are blocked.
Solution: Clean clogged parts.
•
Air escapes from the spray nozzle
even though the trigger is in its initial
position
Possible cause: Valve bolt is jammed.
Solution: Pour oil onto the valve bolt and/or into the compressed air intake.
Operate the trigger several times.
•
Material exits the spray nozzle
even though the trigger is in its initial
position.
Possible cause: The nozzle needle is jammed or dirty.
Solution: Clean the nozzle needle, apply oil to the nozzle needle and/or
slightly reduce the pressure on the nozzle needle seal using a 9mm wrench.
In order to ensure error-free use, a clamping effect on the nozzle needle seal
must remain. Press the trigger several times.
