Conversion and repair

If a jet contour other than those already described is desired, the spray gun has to
be re-tooled. Air cap, material nozzle and needle packing together form a unit - the
nozzle insert assembly. Always change the complete insert assembly to maintain the
desired spray finish quality.
Warning
Prior to any repairs/replacements: Make sure that the spray gun is in unpressurized
condition, i.e. air must be shut off - if not, imminent Risk of Injury.
Note
In order to perform the following procedures, please refer to the exploded diagram at
the beginning of these operating instructions.

1. Unscrew the air cap nut (N° 1).
2. Remove the air cap (N° 2).
