of the slots in the upper piston housing is normal. If it
becomes excessive, or if paint pressure drops, the piston
packings need to be replaced.

found in your manual before starting any troubleshooting,
servicing or cleaning.

Removing the piston rod assembly
Refer to the parts listing for the fluid section assembly.
1. Position the inlet valve housing (28) in a vise so that the
fluid section is vertical. Tighten the vise.
2. Position a large adjustable wrench on the wrench flats of
the cylinder (8). Turn the cylinder counterclockwise until
the cylinder is removed from the inlet valve housing.
3. Remove the inlet valve housing from the vise. Remove the
inlet ball stop disk (23) and tap out the inlet ball cage (25).
NOTE: If any parts are difficult to disassemble, soak
them in an appropriate solvent until the paint
softens.
4. Remove the inlet valve carbide seat (26). Inspect the inlet
valve ball and the inlet ball seat for damage. If the seat is
worn or damaged, it can be flipped to the unused side. If
you flip or replace the seat, the ball must be replaced.
NOTE: If the carbide valve seat requires replacement,
use valve kit P/N 0294689.
5. Remove the inlet valve seat O-ring (27) from the inlet
valve housing.
6. Position the wrench flats of the cylinder (8) in a vise and
tighten the vise.

CAUTION
Hold a hand under the piston rod (10). The piston rod
may be damaged if it falls. The lower packings may also
fall out.
