GLOSSARY OF TERMS

Air Filter
Porous element contained within a metal or plastic housing
attached to the compressor cylinder head which removes
impurities from the intake air of the compressor.
Air Tank
Cylindrical component which contains the compressed air.
Belt Guard
Protects the operator from coming in contact with the belt
and rotating pulleys.
Cut-In Pressure
The low pressure at which the engine speed will automatically
increase to full speed.
Cut-Off Pressure
The high pressure at which the engine speed will automatically
decrease to idle speed.
NPT (National Pipe Thread)
A seal thread tape must be used to provide a leak-free seal
on pipe threaded connections.
On/Off Switch
Control which turns the air compressor on or off. The
pressure switch will not automatically start and control the
compressor unless the manual on/off switch is in the ON ( l )
position.
Pressure Regulator Knob
Regulates the outgoing pressure from the air outlet to the
tool. It is possible to increase or decrease the pressure at
the outlet by adjusting this control knob.

SPECIAL TERMS

Belt Tensioner Bolt
This bolt moves the engine toward or away from the pump
to allow you to reposition or replace the drive belt.
Compressor Tank
The air compressor and 4 gallon stationary tank.
Quarter Turn Drain Valves
Quarter turn drain valves are located on tanks for easy drain-
ing of condensate to help prevent tank corrosion.
Removable Tank
The 4 gallon tank that is removable.
Unregulated Air Hose
This hose transmits the compressed air from the compressor
tank to the removable tank.
Pressure Unloader
Controls the speed of the compressor's engine. The engine
runs at idle speed when the cut-off pressure in the tank is
reached and switches the engine to full speed once the
pressure drops below the cut-in pressure.
PSI (Pounds Per Square Inch)
Measurement of the pressure exerted by the force of the
air. The actual psi is measured by a pressure gauge on the
compressor.
Pump
Produces the compressed air with a reciprocating piston
contained within the cylinder.
Quick-connect Couplers
The 1/4 in. quick-connect couplers allow the operator to
easily attach air hoses to the compressor.
Outlet Pressure Gauge
Displays the current line pressure. Line pressure is adjusted
by rotating the pressure regulator knob.
Safety Valve
Prevents air pressure in the air tank from rising over a
predetermined limit.
SCFM (Standard Cubic Feet Per Minute) or CFM (Cubic
Feet Per Minute)
A unit of measure of air delivery.
Tank Pressure Gauge
Indicates the pressure in the air tank.
Unregulated Air Quarter Turn Ball Valve Lever
This valve opens to allow compressed air to flow from the
compressor tank to the removable tank and closes to stop
air flow from the compressor tank to the removable tank.
Unregulated Air Intake Coupler
This coupler is an air inlet only for the unregulated air hose
and is located on the removable tank.
Unregulated Air Fitting
This 1/4 in. NPT quick-connect fitting connects the unregu-
lated air hose and is located on the compressor tank.
