Flexzilla Electric Operated, Oil-Free Portable Air Compressors
5. TROUBLESHOOTING
Problem Possible Cause Repair
Pressure drop in the tank. Air leaks at connecons. Let the compressor build pressure in the tank, to the
maximum pressure if possible. Brush soapy water on air
connecons and look carefully for air bubbles. Tighten
leaky connecons. If the problem persists, contact
Customer Support for further advice.
The unloader valve leaks when
the compressor is idle.
Unloader valve seal is defecve. Let the air in the air tank ow out unl all the pressure is
released. Then remove the unloader valve plug and clean
the valve seal. If necessary, replace the seal and then
reinstall all components.
The compressor stopped and
does not start.
The thermal protecon turned
on because the motor is
overheang.
Check that the main voltage corresponds to the air
compressor specicaons. An extension cord that is too
thin or too long can cause a voltage drop and cause the
motor to overheat.
Excessive use (over 1 hour connuous use) can cause the
motor to overheat.
Allow the motor to cool down.
Motor windings are burned out. Contact Customer Support.
The motor does not start and
makes a humming noise.
Capacitor is burned out. Contact Customer Support.
The motor does not start or
starts slowly.
Low voltage supply to the motor. Check that the main voltage corresponds to the air
compressor specicaons.
An extension cord that is too thin or too long can cause a
voltage drop. Use heavy duty extension cords.
Ensure that the air compressor is plugged into a fully
funconal power outlet.
The compressor is noisy with
metallic clangs.
Compressor head gasket or reed
valve is damaged.
Stop the compressor and contact Customer Support.
The compressor does not reach
the maximum pressure.
Compressor head gasket or reed
valve is damaged.
Stop the compressor and contact Customer Support.
The compressor doesn’t seem
to provide as much air as it
did when new and/or the
compressor cuts o within a
much shorter me period.
The pressure switch needs
adjusng.
Stop the compressor and contact Customer Support.
The tank is full of water due to
condensaon.
Open the drain valve and release the water from the tank.
The motor pump unit does not
stop when the tank pressure
reaches its maximum working
pressure.
Pressure switch is defecve or
needs adjusng.
Stop the compressor immediately and contact Customer
Support.
