MAINTENANCE - CLEANING THE INLET VALVE

Cleaning or servicing the inlet valve may be required if the unit has priming problems.
i
Priming problems may be prevented by properly cleaning the sprayer and following the
long-term storage steps.
YOU WILL NEED
8 mm (5/16") hex wrench
Needle nose pliers
Warm, soapy water if using latex material
Mineral spirits for oil based material
Household oil (such as 10W30 motor oil or vegetable oil for example)
1.
Perform the Pressure Relief Procedure, found in the main instruction
manual, to ensure the pump is shut off and depressurized. Remove
the tank lid.
Remove the inlet filter (1).
Using the lid as a tray for the parts, insert an 8 mm (5/16") hex wrench
into the hex opening (2) and unscrew the inlet valve fitting (2) from
the sprayer.
You may need to use a ball point pen, tweezers, screwdriver, O-ring
pick, and/or needle nose pliers to remove the inlet valve seat (3),
inlet valve ball (4), spring (5), and O-ring (6). A spare spring (5) is
included with your sprayer.
Suggestion for removal of the inlet valve assembly
i
After removing the inlet filter (1) insert an 8 mm (5/16")
hex wrench into the hex opening (2) and unscrew the inlet
valve fitting (2) from the sprayer.
Snap the lid back onto the sprayer, turn it upside down,
and tap the bottom of the sprayer a few times to loosen
the inlet seat (3), ball (4), and spring (5).
With the sprayer still upside down carefully remove the
lid. Be careful not to lose any of the removed parts unless
you plan to replace them instead of clean them.
Flip the sprayer right-side up again and remove the O-ring
(6) with an O-ring pick or tweezers.
Inspect and clean the inlet valve housing area where the inlet valve
assembly was removed with the appropriate cleaning solution.
2.
Lubricate the O-ring (7) with household oil and install onto the inlet
fitting (8). Lubricate the O-ring (7) once more after it is installed on
the inlet fitting.
3.
Replace all parts back into the inlet valve housing in the reverse order
of how they were removed.
Note the correct orientation of the inlet valve seat (3). The taper
should be facing downward upon reinstallation.
Replace inlet valve fitting (2) by screwing it into the sprayer. Tighten
securely with a 8mm (5/16") hex wrench. Torque to 50-57 in. lbs (5.5
- 6.5 N.m). Do not overtighten the inlet valve fitting.
