P130WJDU Speed and Pressure Regulator Adjusting Instructions
Normally, speed and pressure regulation requires no adjusting, but if proper adjustment is lost, proceed
as follows. Refer to the General Data table for proper engine speeds.
Before Starting
1.
Remove regulator valve cover (A), (if equipped) on valve (B) to expose adjusting screw (C).
Loosen jam nut (D) on adjusting screw (C) and turn screw counterclockwise until tension is no
longer felt on screw. Now, turn screw clockwise one full turn.
2.
Close service valve(s).
After Starting Unit
3.
Allow unit to warm up at least five minutes, then if equipped, place the Start--Run Valve Switch in
the “AIR” position to obtain full service air pressure.
4.
With Service Air Valve closed, turn the adjusting screw (C) clockwise until the discharge pressure
reaches 120 psi (range =20psi). Tighten jam nut (D).
5.
Replace regulator valve cover (A), if equipped.
6.
To select any pressure range fro 85 to 100 psi, change adjusting screw (C) to obtain a “closed”
service valve pressure that is 20 psi greater than the desired “working” service pressure. Always
lock and protect pressure setting of adjusting screw (C) with jam nut (D) and regulator valve cover
(A).
