Your Speedaire Compressor Head (air pump) is a two-stage,
heavy-duty, industrial unit. Each unit is equipped with a
centrifugal unloader for loadless starting, counter-balanced,
ductile, Iron crankshaft, Timken tapered roller bearings and
Die-cast aluminum cylinders. The Compressor Head also
features Swedish steel disc-type valves, finned intercooler,
splash lubrication system, visual oil-level gauge and balanced,
fan-type flywheel (rotates CCW facing flywheel).
MODEL 3Z182B utilizes pressure switch control for
intermittent duty applications (start-stop operations).
MODEL 3Z183B uses constant speed control for continuous

General Safety Information
Because the Compressor Head (Air Pump) is an integral part
of the air compressor system, the following safety precautions
should be observed at all times:
Read the instruction manuals for each component
carefully before attempting to assemble, disassemble or
operate your particular system.
Do not exceed the pressure rating of any component in
Protect material lines and air lines from damage or
Never point a spray gun at oneself or any other person.
Accidental discharge may result in serious injury.
Check hoses for weak or worn condition before each
use, making certain that all connections are secure.
Release all pressures within the system before
attempting to service any component.
Follow all local electrical and safety codes, as well as
Occupational Safety and Health Act (OSHA).
On engine driven units, check engine oil and fuel levels
before starting. DO NOT ADD GASOLINE TO A HOT
Electric motors must be securely and adequately
grounded. This can be accomplished by wiring with a
grounded, metal-clad raceway system, by using a
separate ground wire connected to the bare metal of the
motor frame, or other suitable means.
Always disconnect power source before working on or
near a motor or its connected load. If the power
disconnect point is out-of-sight, lock it in the open
position and tag to prevent unexpected application of
All moving parts should be guarded.
Be careful when touching the exterior of an operating
motor - it may be hot enough to be painful or cause
injury. With modern motors this condition is normal if
operated at rated load and voltage - modern motors are
built to operate at higher temperatures.
Protect the power cable from coming in contact with
Do not kink power cable and never allow the cable to
come in contact with oil, grease, hot surfaces, or
Make certain that the power source conforms to the
requirements of your equipment.
When cleaning electrical or electronic equipment,
always use an approved cleaning agent such as dry
Wiping or cleaning rags and other, flammable waste
materials must be placed in a tightly closed metal
container and disposed of later in the proper fashion.
