DESCRIPTION OF OPERATION

Air  Compressor  Pump: 

 To compress air, the piston

moves up and down in the cylinder. On the downstroke, air

is drawn in through the intake valves.  The exhaust valves

remain  closed.    On  the  upstroke  of  the  piston,  air  is

compressed.  The intake valves close and compressed air

is forced out through the exhaust valves, through the outlet

tube, through the check valve and into the air tank.  Working

air is not available until the compressor has raised the tank

pressure above that required at the air outlet.

Check Valve: 

 When the air compressor is operating, the

check valve is “open”, allowing compressed air to enter the

air  tank.    When  the  air  compressor  reaches  “cut-out”

pressure, the check valve “closes”, allowing air pressure to

remain inside the air tank.

Pressure  Switch: 

  The  pressure  switch  automatically

starts the motor when the tank pressure drops below the

factory set “cut-in” pressure.  It stops the motor when the

air tank pressure reaches the factory set “cut-out” pressure.

Regulator: 

 The air pressure coming from the air tank is

controlled by the regulator.  Turn the regulator knob clock-

wise to increase pressure and counterclockwise to

decrease  pressure.  To  avoid  minor  readjustment  after

making a change in pressure setting, always approach the

desired pressure from a lower pressure.  When reducing

from a higher to a lower setting, first reduce to pressure less

than that desired, then bring it up to the desired pressure.

See front cover.

Extension Cords

Use extra air hose instead of an extension cord to avoid

voltage drop and power loss to the motor.

If an extension cord must be used, be sure it is:

•

a 3-wire extension cord that has a 3-blade ground-

ing plug, and a 3-slot receptacle that will accept the

plug on the compressor.

•

in good condition.

•

no longer than 50 feet.

•

14 gauge (AWG) or larger.  (Wire size increases as

gauge number decreases.)  12 AWG, 10 AWG and

8 AWG may also be used.  DO NOT USE 16 OR 18

AWG.

ation of the Air Compressor

Your compressor comes to you completely assembled

and ready for use.  Operate the air compressor in a dry,

clean, cool and well ventilated area.  The air compressor

pump and case are designed to allow for proper cooling.

Clean  or  blow  off  dust  or  dirt  that  collects  on  the  air

compressor.  A clean air compressor runs cooler and

provides longer service.  The ventilation openings on your

air compressor are necessary to maintain proper operating

temperature.  Do not place rags or other containers on or

near these openings.

Voltage and Circuit Protection

Depending  on  the  air  requirements  of  each  particular

accessory, the outlet regulated air pressure may have to be

adjusted while operating the accessory.

Outlet  Pressure  Gauge: 

  The  outlet  pressure  gauge

indicates the air pressure available at the outlet side of the

regulator.  This pressure is controlled by the regulator and

is always less or equal to the tank pressure. See “Operat-

ing Procedures”.

Tank Pressure Gauge: 

 The tank pressure gauge indi-

cates the reserve air pressure in the tank.

Cooling System:

  This compressor contains an advanced

design cooling system. At the heart of this cooling system

is an engineered fan. It is perfectly normal for this fan to blow

air through the vent holes in large amounts. You know that

the cooling system is working when air is being expelled.

Air Intake Filter: 

 This unit requires no air filter due to the

unique design of the air intake system.

Drain Valve: 

 The drain valve is located at the base of the

air tank and is used to drain condensation at the end of each

use.

On/Auto-Off Switch: 

 Turn this switch ON to provide

automatic power to the pressure switch and OFF to remove

power at the end of each use.
