Unloader Adjustment Procedures

1. Remove lock nut (Item 19).

2. Remove adjustment knob (Item 18).

3. Loosen the two (2) nuts (Item 15), move them upward on stem (Item 8) until you see 4 or more threads below
the nut.

4. Re-attach adjusting knob (Item 18).

5. Start machine. Open the trigger of the spray gun. Increase pressure by turning adjustment knob (Item 18)
clockwise until pressure is at the desired operating pressure.

6. Remove the adjustment knob (Item 18), tighten the lower nut (Item 15) tightly against the upper nut (Item 15).
Re-attach adjustment knob (Item 18) and screw down until contact is made with the nuts (Items 15). Screw
down lock nut (Item 19) onto the stem (Item 8) until the threads cut into the nylon insert of the lock nut 
(Item19).

*

If adjustment knob (Item 18) 

DOES NOT 

make contact with upper nut (Items 15), remove adjusting knob (Item

18), re-adjust (raise) nuts (Items 15) on stem (Item 8) and re-attach adjustment knob (Item 18), then repeat
step #6.

**

If adjustment knob (Item 18) 

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
18) and re-adjust (lower) the nuts (Items 15) on the stem (Item 8). Re-attach the adjusting knob (Item 18), then
repeat step #6.
