Troubleshooting
System OFF, Power ON
Message/Problem
Possible Cause
Corrective Action
HYD OIL TOO COLD
The hydraulic oil
temperature is below
+5F(–15 C).
Pre-heat the hydraulic oil before
running the system.
No power to display box
Fuse popped or bad
connection
Check components, replace fuse
inside Predatair.
ON button pressed/Initial startup
Message/Problem
Possible Cause
Corrective Action
SOFT START XXXPSI
The system has started,
but the compressor oil
temperature is still cool.
The system is in “Unload” Mode,
until the compressor has come up
to temperature +122F(50C).
HYD OIL TOO COLD
The hydraulic oil is below
-13F (-25C).
The system is cautioning the
operator to preheat the hydraulic oil
before starting the PTO system.
The Cold Climate Kit (A700146)
can be installed to speed warm-up
once the hydraulic oil temperature
has reached
–13F(-25C).
HYD OIL WARMING, HYD
XXXF/XXXC
The hydraulic oil is
between
-13F(-25C) and +5F(-15C).
Keep circulating hydraulic fluid until
the system warms sufficiently to
start. If installed, the Cold Climate
Kit (A700146) will speed warm-up.
The Predatair won’t start until the
hydraulic oil has warmed to +5F(-
15C).
PREDATAIR does not
start when the ON button
is pressed.
Inappropriate conditions
for start-up.
Check display box for messages.
Hydraulic solenoid failure.
Check solenoid and connections.
Hydraulic motor or
compressor seized.
Check motor and compressor will
roll-over.
Running
Message/Problem
Possible Cause
Corrective Action
STANDBY XXXPSI
The air pressure stayed
above the restart pressure
for the duration of the
standby delay time.
The hydraulic solenoid is off, and
the system is monitoring air
pressure and compressor and
hydraulic oil temperatures. If the
air pressure drops below the restart
pressure, or the compressor oil
temperature drops below its
minimum, it will restart and rebuild
air.
Air pressure won’t build
past approx. 40psi.
The system is in SOFT
START.
Wait for the compressor to warm
up.
Unload solenoid on inlet
valve has failed or problem
with wiring connections
Check solenoid and wiring.
