For Malfunction During Operation - NorthStar M4592900A.4 Owner's Manual

When using a paint spray or sandblast gun, this water
will be carried from the tank through the hose, and out of
the gun as droplets mixed with the spray material. If this
is not acceptable for your application, an external air
dryer must be added to the system.
WARNING: Risk of bursting
Drain air receiver tank daily or after each use to prevent
moisture buildup in the air tank. Serious injury or death
may occur from a tank explosion caused by moisture
induced tank corrosion.

For Malfunction During Operation

Immediately turn off the compressor pump if any of the
following conditions arise during operation:
Excessive change in motor speed, slow or fast

Overheating

Excessive vibration

Unusual noise

Flame or smoke

Air leakage

Pull ring on safety valve to immediately relieve pressure.
WARNING: Shutdown hazards
Do not leave an operating machine unattended. Always
shut the machine OFF and relieve the pressure before
leaving the machine. NEVER disconnect the high-
pressure outlet hose from the unit while the tank and air
line are pressurized. A hazardous high pressure air
stream will result as receiver tank is quickly emptied.
