System Component Information
II. How to adjust the air regulators.
See Fig. 4.
1. Always open air regulators slowly to prevent
surging during startup.
2. As you look at the system, the regulator (36) on
the right controls air to the gun and the regulator
(33) on the left controls air to the pressure pot.
3. Model 237409 has two T-handle air regulators (33
and 36). Model 237413 (shown in Fig. 4) has one
T-handle air regulator (36) and one air regulator
with an adjustment knob (33).
T-Handle Air Regulator
Turn the T-handle (36 and 33–Model 237409 only) in
(clockwise) to open the air regulator and turn the
T-handle fully out (counterclockwise) to close it. Be
sure the jam nut under the T-handle does not interfere
with your adjustments. Tighten the jam nut to lock in
the setting, if desired.
Air Regulator with Adjustment Knob
Model 237413 only
Pull out the adjustment knob (33), and turn the knob in
(clockwise) to open the air regulator; turn the knob fully
out (counterclockwise) to close it. Push the adjusting
knob in to lock the setting if desired.

III. Safety relief valve
See Fig. 4.
The safety relief valve (4) automatically relieves the
pressure pot pressure when the air pressure exceeds
approximately 100 psi (0.7 MPa, 7.0 bar). It resets
automatically when the pressure is relieved. Refer to
the test procedure in manual 308369.
