9.2 Cases of Failure
Drops form on the trigger
The needle gasket (10.1) is either worn or loose and must slightly be retightened. For that purpose remove
needle/valve cartridge (see section 6.4). Then unscrew screw (12.2) and take out needle driver (12.1). Using
a small screw driver turn stuffing box (11.1) gently clockwise and try if needle is sliding smoothly again within
the tightening gasket.
Drops form on the nozzle
Either the needle or the nozzle is worn and should be replaced. Or needle is not closed properly because of
particle residues within nozzle. Clean the needle/valve cartridge with solvent (see section 6.2).
Uneven and not steady spray jet
Make sure that nozzle is screwed in tight. Other reason could also be dirt residue within air cap. Clean air
cap with solvent.
Air is blowing constantly although trigger is released
O-Ring (13.1) and/or washer (14.1) are worn and must be exchanged. Or needle nuts are not counter-
screwed in correct position (see section 6.4).
