Fluid Packing Rod Removal and Repair
NOTE: The fluid packing rod can be replaced as indi-
vidual parts or as an assembly.
If the assembly is pur-
chased, it is pre-adjusted at the factory.
1. Prepare the gun for service as instructed on
page 29.
2. Remove the air cap assembly and the gun shroud.
3. Remove the jam nut (46) and actuator arm (19).
See Fig. 25 on page 33.
NOTE: The fluid nozzle must be in place when remov-
ing or installing the jam nut and actuator arm.
4. Remove the fluid nozzle, resistor stud, and elec-
trode needle as instructed on page 30.
5. Remove the fluid packing rod assembly (28) with
the 9 mm hex nut driver (79). See Fig. 23.
6. Clean all the parts, and check them for wear or
damage. Replace the parts if necessary.
Before installing the fluid packing rod assembly
(28), clean the internal surfaces of the barrel with a
soft brush or cloth. Check the inside of the barrel
for marks from high voltage arcing. If the marks
are present, replace the barrel.
CAUTION
Clean all the parts in non-conductive solvent com-
patible with the fluid being used, such as xylol or
mineral spirits. Use of conductive solvents can
cause the gun to malfunction.
