OPERATING INSTRUCTIONS (CONTINUED)
On/Off Cycling of Compressor
damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.
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.
Drain Tank. Disconnect, tag, unplug and lock out
power source; release pressure. Drain moisture from
tank by opening drain valve underneath tank (See
Figure 8).
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.
Risk of Bursting. Drain tank every day to prevent corrosion and possible injury due
to tank damage. Do not operate drain with more than 40 psi in tank or drain valve may be
Unit care and maintenance. Drain liquid from tank daily.
