DESCRIPTION OF OPERATION (cont'd)

PreSsureReleaseValve: The pressurereleasevalvelocatedon the side of the pressure switch, is designed to automatically releasecompressed airfrom thecompressor head andtheoutlet tube when the air compressor reaches "cut-out" pressure or is shut off. If the air is not released,the motorwilltryto start, but will

be unable to. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this Valve for a few seconds. No air should be heard leaking when the motor is running, or continuous leaking

after unit reaches cut-out pressure.

Pressure Switch: The pressure switch automaticallystarts the motorwhenthe airtank pressuredrops belowthefactory set"cut- in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-out" pressure.

Safety Valve: If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the safety valve will protect against high pressure by "popping out" at its factory set pressure(slightly higherthanthe pressureswitchcut-outsetting).

Outlet Pressure Gauge: The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled bythe regulatorand is always lessorequal to the tank pressure. See "Operating Procedures".

Tank Pressure Gauge: The tank pressure gauge indicatesthe reserve air pressure in the tank.

Regulator: The air pressure coming from the air tank is con- trolledbythe regulatorknob.Turnthe knobclockwisetoincrease pressure and counterclockwiseto 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 some pressurelessthanthatdesired,then bring uptothedesired

pressure. Depending on the air requirements of each particular accessory, the outlet regulated air pressure may have to be adjusted while you are operating the accessory.

-INSTALLATION AND BREAK-IN PROCEDURES -

location of the Air Compressor

Locate the air compressor in a clean, dry and well ventilated area.The air filter must be kept clear of obstructionswhich could reduce air delivery of the air compressor. The air compressor should be located at least 12" away from the wall or other obstructions that will interfere with the flow of air. The air compressor head and shroud are designed to allow for proper cooling. If humidity is high, an air filter can be installed on the air outlet adapter to remove excessive moisture. Follow the instructions packaged with the air filter for proper installation.

Lubrication and Oil

This unit needs no lubrication or oiling.

Extension Cords

To avoid voltage drop, power loss,and overheating of the

.. .. motor, use an extra air hose instead of an extension cord.

Low voltage can cause damage to the motor.

If an extension cord mustbe used:

use only a 3-wire extension cord that has a 3-blade ground- ing plug and a 3-slot receptaclethat will accept the plug on

the air compressor.

make sure the extensioncord is in good condition.

the extension cord should be no longerthan50feet.

the minimum wire size is 12 gauge (AWG). (Wire size

increasesas gauge number decreases. 10AWG and 8 AWG may also be used. DO NOT USE 14 AWG or 16 AWG.)

Piping (cont'd)

If a pipe line is necessary, use pipe that is the same size as the air tank outlet. Pipingthat is too small will restrictthe flow of air. If piping is over 100 feet long, use the next larger size. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pres;ure before underground lines are covered to make sure all pipe joints are free of leaks.

GROUNDING INSTRUCTION

RISK OF ELECTRICALSHOCK! Inthe event o t a shortcircuit, grounding reducesthe riskof shock by providing an escape wire for the electric current. This air compressor must be properly grounded.

The air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be used with an outletthat hasbeen installed and grounded in accordance with all local codes and ordinances. The outlet must have the sameconfiguration astheplug. Seeillustration.DONOTUSEAN

ADAPTER.

Inspect the plug and cord before each use. Do not use if there are signs of damage.

Piping

Plastic o r PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure, Use only metal pipe for air distribution lines.

IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.

Do not modifytheplug that has been provided. If it does not fit the available outlet,the correct outlet should be installedby a qualifiedelectrician.
