Using Compressor for Spraying

Flammable Materials

Always follow precautions on container labels or MSDS
before spraying flammable materials, such as paint.

Moisture in Compressed Air

Moisture in supply air when compressed will form into
droplets as it leaves air compressor pump and enters
receiver tank. When humidity is high or when a
compressor is in continuous use for an extended period
of time, a significant amount of moisture will collect in
the tank. Part of the moisture will be discharged in the
outlet air.
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.

Procedure

When you are finished using the compressor:
1. Move the pressure switch to the OFF position.
2. Turn regulator counter clockwise to close.
3. Unplug the power cord.
4. Operate tools briefly to release live pressure
5. Disconnect all tools.
6. Drain air receiver tank by pulling safety relief
valve.
7. After all storage air discharges, disconnect hoses.
8. Once the tank pressure gauge registers under 10
PSI, open the drain valve on the bottom of the
tank to drain condensation moisture.
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 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.
