System Component Information
III. How to adjust the air and fluid
regulators (Fig. 8)
1. Always open air and fluid regulators slowly to
prevent surging during startup.
2. The fluid regulator (6) controls fluid from the pump
to the gun. For an accurate setting, adjust the fluid
regulator only when the gun is triggered and fluid is
flowing through the regulator. Be sure the jam nut
(H) under the T–handle does not interfere with
your adjustments. Tighten the jam nut to lock in
the setting, if desired.
3. To open the fluid regulator, which allows fluid to
flow, turn the T-hand IN (clockwise).
4. To close the fluid regulator, which restricts or shuts
off the fluid flow, turn the T-handle OUT (counter-
clockwise).
5. As you look at the system in Fig. 8 the air regulator
(5a) on the left of the pump controls air to the
pump and the regulator (5b) on the right controls
the air to the gun.
6. To open the air regulator, pull out the adjusting
knob. Turn the knob IN (clockwise) to open and
turn the knob fully OUT (counterclockwise) to
close. Push the adjusting knob in to lock the
setting, if desired.
