Operation
Pressure Relief Procedure
With the Evenflo control, its bypass valve, and the
pump Relax-A-Valve properly set, fluid pressure is
relieved from the pump and hose each time you re-
lease the gun trigger. Always engage the gun trigger
safety when you stop spraying. To relieve air pressure,
close the Evenflo regulators and open the bleed-type
master air valve.
WARNING
INJECTION HAZARD
If you suspect that the Evenflo system is
not properly set, or that pressure is not
fully relieved, the system pressure must
be manually relieved to prevent the system from
starting or spraying accidentally. Fluid under high
pressure can be injected through the skin and
cause serious injury. To reduce the risk of an injury
from injection, splashing fluid, or moving parts, fol-
low the Pressure Relief Procedure whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tips.
1. Close the air regulators.
2. Open the bleed-type master air valve.
3. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
4. Lock the gun trigger safety.
5. Carefully loosen a fluid hose fitting and relieve
pressure gradually.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.
Relax-A-Valve Automatic Position
To set the pump Relax-A-Valve (G) in the automatic
position, loosen the locknut (H), turn the T-handle (J)
clockwise as far as possible, and then back-off the
handle four turns and tighten the nut. See Fig. 3.
NOTE: Every time you resume spraying, ensure that
the Relax-A-Valve is in the automatic position.
