OPERATING INSTRUCTIONS
Start-up / Break-in Procedure
Do not attach air tools to open end of the hose until start-up is completed and the unit checks
okay.
Never disconnect threaded joints with pressure in tank!
1. Return power to unit from main.
2. Check oil level per the Lubrication Section of this manual.
3. Open the tank drain valve (see Figure 16). Turn outlet valve to open air flow.
4. Move pressure switch to the AUTO position to run the unit (see Figure 17).
5. Run the unit for thirty (30) minutes at zero (0) PSI (under no load) to break in pump parts.
6. Move the pressure switch lever or knob to OFF and turn tank drain valve to shut off air flow. The
compressor is now ready for use.
7. Change oil after first fifty (50) hours of operation. Perform oil changes every three (3) months or two
hundred (200) hours of run time, whichever comes first.
On/Off Cycling of Compressor
Drain tank every day to prevent corrosion and possible injury due to tank damage. For optimal
performance of tank drain, tank pressure should be between 10 PSI - 40 PSI. Do not operate
drain with more than 40 PSI in tank or drain valve may be damaged. Drain tank of moisture daily using the drain valve
in the bottom of the tank.
Drain liquid from tank daily.
In the AUTO position, the compressor pumps air into the tank. When a shut-off (preset “cut-out”) pressure
is reached, the compressor automatically shuts off.
If the compressor is left in the AUTO position and air is depleted from the tank by use of a tire chuck, tool,
etc., the compressor will restart automatically at its preset “cut-in” pressure. When a tool is being used
continuously, the compressor will cycle on and off automatically.
In the OFF position, the compressor will not operate.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor pump. When
humidity is high or when a compressor is in continuous use for an extended period of time, this
moisture will collect in the tank. 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.
IMPORTANT:
This condensation will cause water spots in a paint job, especially when spraying other
than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering
it ineffective. A filter in the air line, located as near to the gun as possible, will help eliminate this
moisture.
