Unloader Adjustment Procedures
Remove lock nut (Item 7).
Remove adjustment knob (Item 8).
Loosen the two (2) nuts (Items 25), move them upward on stem (Item 14) until you see 4 or more threads below the nut.
Re-attach adjusting knob (Item 8).
Start machine. Open the trigger of the spray gun. Increase pressure by turning adjustment knob (Item 8) clockwise until
pressure is at the desired operating pressure.
Remove the adjustment knob (Item 8), tighten the lower nut (item 25) tightly against the upper nut (Item 25). Re-attach
adjustment knob (Item 8) and screw down until contact is made with the nuts (Item 25). Screw down lock nut (Item 7)
onto the stem (Item 14) until the threads cut into the nylon insert of the lock nut (Item 7).
*If adjustment knob (Item 8) DOES NOT make contact with upper nut (Item 25), remove adjusting knob (Item 8), re-adjust
(raise) nuts (Items 25) on stem (Item 14) and re-attach adjustment knob (Item 8), then repeat step #6.
**If adjustment knob (Item 8) DOES make contact with upper nut, release the trigger of the spray gun and watch the pressure
gauge for the pressure increase (“spike”). This “spike” SHOULD NOT exceed 500 psi above the operating pressure. If spike
pressure exceeds the 500 psi limit, remove the adjusting knob (Item 8) and re-adjust (lower) the nuts (Items 25) on the stem
(Item 14). Re-attach the adjusting knob (Item 8), then repeat step #6.
