connect fitting on the main compressor outlet or after the
user installed regulator.
CAUTION: Air tools hazard
Do not attach air tools to open end of the hose until
start-up is completed and the unit checks out OK.
Quick Connect Procedure:

Keep finger off tool or activation switch until ready
to use.

Pull quick connect collar back (Figure 14a).

Push hose or attachment firmly against stop.

Let go of collar (Figure 14a).

Pull and rotate slightly (hose or attachment) to
assure a tight connection.
WARNING: Projectile hazard
Air tool or attachment can become a projectile and
cause serious personal injury or damage if not securely
attached to the air hose.

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.
Shutdown
Procedure
When you are finished using the compressor:
1. Move the pressure switch to the OFF position.
2. Close the ball valve to stop airflow.
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 is discharges, disconnect
hoses and open the ball valve.
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.
