and contact customer support.
Pressure reading on
the outlet pressure
gauge drops when a
tool is used.
It is normal for the gauge to show a minimal pressure
loss during initial use of a tool. First try to adjust the
outlet pressure while the tool is being used, if there is an
excessive amount of pressure drop while the tool is used,
replace the pressure regulator.
Excessive tank
pressure.
Turn power switch to OFF. If the unit does not shut off,
unplug the power cord from receptacle and contact
customer support.
Motor will not start.
Make sure the power cord is plugged in and power switch
is set to ON. Inspect for the proper size circuit breaker in
your electrical panel. If the breaker was tripped, reset, and
restart the unit. If repeated tripping occurs, replace the
check valve, or contact customer support.
Excessive moisture in
the discharge air.
Water condensation occurs normally when compressing
air. Remove water condensation in the tank by draining
after each use. High humidity environments will cause
excessive condensation. Add water lters on your air line
for extra protection from water corrosion.
