SAFETY PRECAUTIONS
AIR COMPRESSOR HAZARDS
• It is normal to have some sparks within the motor and pressure switch.
• Do not let the compressor come into contact with flammable vapors, as the sparks from
the motor and pressure switch may ignite the flammables and cause an explosion.
Always operate the compressor in a well-ventilated place free of flammable vapors.
• Do not restrict any of the air compressors ventilation openings; as this will cause
overheating and cause potential fires.
• Do not allow the compressor to operate unattended. Unattended operation of this product
could result in accidents.
• Drain the tank daily after operation to prevent rusting and thinning of the steel tank.
• Never modify or repair the air tank. Doing so will weaken the structural integrity of the
air tank and lead to danger.
• The tank is designed to withstand specific operating pressures. Therefore, do not modify
or alter the unloader valve or any other components of the tank.
• Excessive vibrations can weaken the air tank and cause rupture or explosion.
• When operating the air compressor, always wear safety glasses with side shields.
• Always turn the compressor off and bleed the pressure from the air hose and tank before
beginning maintenance, or attaching tools or accessories.
ELECTRICAL SAFETY
• Your air compressor is powered by electricity, therefore, do not operate the compressor
outdoors when it is raining or in wet conditions.
• Any electrical repairs should be performed by an authorized service center professional.
Repairs attempted by unqualified personnel can result in serious injury or death by
electrocution.
• Always make sure the air compressor is properly grounded.
VENTILATION
• Do not inhale the air from the air tank as this air may contain carbon monoxide, toxic
vapors, or solid particles from the tank. These contaminants can cause serious injury or
death.
• Always work in an area with good ventilation. Sprayed materials such as paint, paint
solvents, paint remover, insecticides, weed killers, may contain harmful vapors and
poisons.
• Always wear proper safety masks and wear safety equipment when working with sprayed
chemicals and particles.
RISK FROM INJURY
• Do not touch any exposed metal parts on the compressor, as it remains hot for several
minutes after operation.
• Never operate the compressor with the guards or covers removed. Moving parts such as
a pulley or flywheel can cause serious injury if they come into contact with you or your
clothing.

5
• Authorized service center personnel should perform repairs.
• Portable compressors can fall from tables or rooftops causing serious injuries or death to
the operator. Always operate the compressor in a stable secure position to prevent
accidental movement of the unit. Do not operate the compressor on a roof or other
elevated positions. Use more air hose to reach high locations.
• When transporting the compressor, always use a protective mat as fluids from the
compressor may leak or spill. Leaks can damage carpet, paint or other surfaces in
vehicles or trailers.
• Please read and follow the instructions outlined in this manual before operating your
compressor. Unsafe operation of your air compressor could lead to serious injury or
death to you or others.
ASSEMBLY
CAUTION
DO NOT OPERATE THIS AIR COMPRESSOR WITHOUT FIRST ADDING OIL TO
THE CRANKCASE. Major damage will result from even limited operation unless filled
with oil and broken in properly. Be sure to follow all initial start up procedures.
CAUTION
COMPRESSORS ARE SHIPPED WITHOUT OIL AND MAY HAVE A SLIGHT
AMOUNT OF OIL IN THEM FROM TESTING AT THE FACTORY. Be sure to fill oil to
proper level before operation.
CAUTION
Use only SAE30 (API CG/CD heavy duty motor oil). Make sure unit is on a level surface
before adding oil. Also, use the oil viewing glass to see the oil level. When adding oil, be
careful not to fill the oil too fast as it may overfill suddenly.

INSTALLATION
INSTRUCTIONS ON SETTING UP YOUR UNIT
To begin setting up your compressor
• Begin setting up the air compressor in clean, dry, and well-ventilated area.
• Keep the compressor at least 1 foot away from the wall or other objects that may interfere
with the flow of air.
• Keep the air filter clear of obstructions, as this will reduce the airflow into the
compressor.
• Do not allow the compressor to get wet, as this will cause electrical shock. The air
compressor requires a fresh airflow for proper air-cooling.
GROUNDING INSTRUCTIONS
WARNING
Grounding provides an escape wire for the electric current resulting from a short circuit. In order
to ensure your safety, this air compressor must be properly grounded. The air compressor comes
equipped with a cord having a grounding wire and a grounding plug.
• The cord and plug should be plugged into a grounded outlet.
CAUTION: The outlet begin used must be installed and grounded in accordance with all local
codes and ordinances.
• Verify that the outlet being used has the same configuration as the grounded plug. DO
NOT USE AN ADAPTER. See illustration.
• Always inspect the cord for damage before using the compressor.
• If these grounding instructions are not fully understood, or doubts are present, please
contact your local qualified technician for assistance.
WARNING
IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.
Do not modify the plug provided. If the plug does not fit the outlet, a qualified electrician should
install a correct outlet. A qualified electrician must make repairs to the cord set or plug.

7
EXTENSION CORDS
It is recommended that more air hose be used instead of an extension cord. Using more
extension cord will cause a voltage drop resulting in power loss to the motor.
If an extension cord must be used, verify that it is:
• A 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that
will accept the plug on the product.
• Extension cord is in good condition
• Length cannot exceed 50 feet.
• Larger than 12 gauge (American wire gauge (AWG)). As the number gets smaller, the
wire gauge gets larger, as the number gets larger, the wire gauge gets smaller.
OPERATION
KNOWING YOUR AIR COMPRESSOR
Read this manual and safety rules before operating the unit. Know all the functions of the air
compressor in case of an emergency.

Gauge
On/Auto/Off Switch: Put this switch in the “ON” position to provide automatic power to the
pressure switch and “OFF” to remove power at the end of each use.
Pressure Switch: The pressure switch automatically starts and stops the air compressor based
on the tank pressure. If the pressure is low, the pressure switch will cut-in and turn the
compressor on. If the pressure in the tank is high, the pressure switch will cutout and turn the
compressor off.

8
Safety Valve: If the pressure switch is malfunctioning and does not turn the compressor off
after the pressure in the tank is too high, there is a safety valve that will protect against high
pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch
“cut-out setting”).
Safety Valve
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 than or
equal to the tank pressure.
Tank Pressure Gauge: The tank pressure gauge indicates the pressure inside the tank.
Regulator: The pressure regulator controls the air pressure shown on the outlet pressure gauge.
To increase the pressure pull the knob out and turn clockwise. To decrease the pressure, pull the
knob out and turn counterclockwise. When the desired pressure is established, push the knob
back into place.
Universal Quick-Connect Body (Not shown): The universal quick-connect body accepts the
three most popular styles of quick-connect plugs- Industrial, automotive, and ARO. One hand
push-to-connect operation makes these connections possible.
Drain Valve: The drain valve is located at the bottom of the tank and is used to drain the
condensation in the tank at the end of each use.
Drain Valve
Cooling System: The compressor is equipped with an air-cooled cooling system. It is normal
for air to be blowing over the pump head, cylinder sleeve, and crankcase. You know the cooling
system is working when air is being expelled.
Air Compressor Pump: Compresses air into the air tank. Working air is not available until the
compressor has raised the pressure in the air tank above that required at the air outlet.
Oil viewing glass: The oil-viewing glass indicates the oil level in the air compressor pump.
Check Valve
Oil Drain
Plug Oil viewing glass
Air Intake Filter

9
Air Intake Filter: This filter cleans the air that comes into the air compressor pump. This filter
should always be clean and free from debris.
Check Valve: The check valve permits air to enter the tank when the air compressor pump is
pumping air. When the air compressor cuts-out, the valve closes and traps the air from leaving
the tank.
HOW TO USE YOUR UNIT
Stopping your unit:
• Set the On/Auto/Off switch to the “OFF” position.
Break in procedure
Break in is required before the air compressor is put into service and when the check valve or air
compressor pump is replaced.
• Verify that the switch is in the “OFF” position.
• Check the oil level in the air compressor pump.
• Make sure there is no air leaking from the quick coupler by pulling the coupler back.
• Plug the power cord into a standard properly grounded wall receptacle.
• Fully open the drain valve to prevent pressure buildup during the break-in period.
• Run the compressor for 20 minutes verifying that there is minimal pressure buildup.
• After 20 minutes, close the drain valve. The air receiver (air tank) will fill to “cut-out”
pressure and the motor will stop.
How to Start:
• Turn the On/Auto/Off switch to the “Auto” position and allow tank pressure to build.
When the tank pressure reaches the “cut-out” pressure, the motor will automatically stop.
• To adjust the output pressure, pull the pressure regulator knob out and adjust the pressure.
Counterclockwise decreases the pressure and clockwise raises the pressure.
NOTE: Always operate the air compressor in a well-ventilated area free of flammable or
combustible vapors. Do not place air compressor near the spraying area.

CAUTION
Before performing any type of servicing, please be sure to disconnect the power source from the
compressor and drain all air from the air compressor. Failing to do so will lead to serious
injuries as compressed air and moving parts can injure you.
To ensure better operation and longer life of the air compressor, a routine maintenance schedule
should be setup and followed. The maintenance schedule above is based upon a normal working
environment and on a daily basis. If the environment conditions or operating times change to
more extreme conditions, then modifications should be made to the maintenance schedule. The
modifications made should depend on the number of hours involved in operating the compressor
as well as the environment involved. Compressors operating in extremely dirty and or hostile
environments require a more frequent maintenance schedule.
NOTES: See “Operation” section for location of controls.
CHECKING THE SAFETY VALVE
WARNING
The safety valve is a critical component in ensuring your safety. If the safety valve does not
work properly, over-pressurization may occur, causing air tank rupture or an explosion.
• Before starting the air compressor, test the safety valve by first pulling on the valve to see
that it moves freely. If the valve is stuck or does not operate smoothly, it must be
replaced with the same type of valve.

11
DRAINING THE AIR TANK
• Put the On/Auto/Off switch to the “Off” position.
• Pull the regulator knob out and turn the knob until the outlet pressure reads zero.
• Remove all the air tools and accessories connected to the air compressor.
• Pull the ring on the safety valve and drain the air from the tank until the tank pressure
reads 20 psi, then release the safety valve ring.
• Drain the condensed water from the air tank by opening the drain valve (counter-
clockwise) on the bottom of the tank. NOTE: Tilt the tank forward to drain the tank
completely.
CAUTION
The tank should be drained daily. Water condenses in the air tank, if the tank is not drained
daily, the condensed water will cause corrosion to the air tank thereby weakening the air tank
and causing a risk of air tank rupture.
• After draining the water from the tank, close the drain valve (clockwise). The air
compressor can now be stored.
OIL
• Drain the air tank to relieve the air pressure before removing the oil fill or oil drain plug.
• Do not touch the compressor head or cylinder sleeve, as they are very hot parts.
CHECKING
• To check the oil level in the air compressor head, first set the On/Auto/Off switch to the
“OFF” position.
• Remove the filler plug to see that the oil level is full.
Oil viewing glass
• If the oil is not sufficient, add oil until the level is sufficient.
• Put the oil plug back in place.
CHANGING THE OIL
• Put the On/Auto/Off switch to the “OFF” position.
• Remove the oil filler plug.
• Remove the oil drain plug and drain the oil into a container.
• Install the oil drain plug and tighten slightly. Be careful not to over-tighten the bolt.
• Fill the compressor head with SAE30 oil until the level is showing full on the oil viewing
glass.

12
AIR FILTER-INSPECTION AND REPLACEMENT
Before servicing your compressor, please let the compressor cool down. When removing parts
from the compressor, there are hot surfaces that can cause severe burns.
WARNING
Dirty air filters will bring down the compressors operating performance. Keep the air filter clean
at all times.
• Remove the air filter cover.
• Remove the air filter from the filter cover.
NOTE: Never operate the compressor without an air filter.
• Place a new air filter into the filter cover. Refer to the “Repair Parts” for the correct part
numbers.
• Replace the air filter cover and lock it into place.
MOTOR
The motor has an automatic overload protector. If the motor overheats, the overload protector
will turn the motor off. In order to restart the compressor, the motor must be allowed to cool
down first. The compressor will automatically restart after the motor cools.
If frequent shutdowns are occurring, verify that the correct voltage is supplied. Low voltage can
be suspected when:
• The motor does not get up to full power or speed.
• Fuses blow out when starting the motor: lights dim and remain dim when motor is
started and is running.
STORAGE
Before storing your air compressor, make sure you do the following:
• Review the “Maintenance” section from the previous sections of this manual and perform
the scheduled maintenance as necessary.
• Set the On/Auto/Off switch to the “OFF” position.
• Adjust the regulator knob until the outlet pressure is zero.
• Remove all air tools and accessories.
• Pull the ring on the safety valve to allow air to bleed from the tank until the tank pressure
is approximately 20 psi. Release the safety valve ring.
• Drain the water from the air tank by opening the drain valve on the bottom of the tank.
NOTE: Water will condense in the air tank. If not drained, water will corrode and
weaken the air tank causing a risk of air tank rupture.
• After the water has drained, close the drain valve.
• Always protect the electrical cord and air hose from damage (such as being stepped on or
run over). Wind them loosely around the compressor handle. (If so equipped)
• Store the air compressor in a clean and dry location.

About Your Product Warranty
Eastern Tools & Equipment, Inc. welcomes warranty repair and apologizes to you for being inconvenienced. Any Authorized
Service Dealer may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes warranty service may
be inappropriate. For example, warranty would not apply if an engine were damaged because of misuse, lack of routine
maintenance, shipping, handling, warehousing, and improper installation. Similarly, warranty is void if the serial number on the
engine has been removed or if the engine has been altered or modified. If a customer differs with the decision of the Service
Dealer, an investigation will be made to determine whether the warranty applies. Ask the Service Dealer to submit all supporting
facts to his Distributor or the factory for review. If the distributor or the factory decides that the claim is justified, the customer
will be fully reimbursed for those items that are defective. To avoid misunderstanding, which might occur between the customer
and the dealer, listed below are some of the causes of engine failure that the warranty does not cover.

20
Normal wears:
Engines and generators, like all mechanical devices, need periodic parts service and replacement to perform well. Warranty will
not cover repair when normal use has exhausted the life of a part of an engine.
Improper maintenance:
The life of an engine or your equipment depends upon the conditions under which it operates, and the care it receives. Some
applications, such as tillers, pumps, and rotary movers, are very often used in dusty or dirty conditions, which can cause what
appears to be premature, wear. Such wear, when caused by dirt, dust, spark pug cleaning grit, or other abrasive material that has
entered the engine because of improper maintenance is not covered by warranty.
