AIR COMPRESSOR
Dust or dust-like particulates caused by
power-sanding, sawing, grinding, drilling or any
other construction-like activities can contain
contaminants that are harmful to breathe.
Always use your air compressor in a well-ventilated
and clean area.
Never breathe the air that comes directly out of the
air compressor or air hose. This air is not suitable for
breathing.
Always wear approved safety equipment. hen
performing dust-creating activities, securely wear
properly-fit face masks or respirators.
If you feel ill from breathing while operating your air
compressor, stop and seek medical attention
immediately.
WARNING
RISK TO BREATHING
Air compressor surfaces become hot during
operation.
DO NOT touch hot surfaces, because they can cause
severe burns.
Do not touch the air compressor’s cylinder head.
During operation, the cooling fins of the cylinder
head and delivery pipe become hot.
Allow the air compressor to cool before touching it.
DO NOT place a storage cover on the unit during
operation. Only place a cover on the air compressor
after it has thoroughly cooled down.
F RE
HOT SURFACE
WARNING
Flying objects can cause injury to the eyes, head and
other parts of the body.
Air-powered equipment and power tools are capable
of propelling items (metal chips, fasteners and
particulates) at high speed into the air and could
result in injury.
Always wear approved head and eye protection.
ever point the air stream at any part of your body,
or at another person or animal.
When operating the air compressor, make sure all
other people and animals maintain a safe distance.
Do not move the air compressor when the air tank is
under pressure.
ever use the air hoses to pull or move the air
compressor.
Keep the air compressor on a flat surface.
WARNING
FLYI G OBJECTS
Exercise caution when using pressurized air.
To prevent injury and for your general safety, only
use high-pressure hoses, fittings and couplings
designed for use with air compressors.
Inspect all hoses, fittings and couplings for leaks
and wear. hen leaks and wear are detected, stop
use and replace those items immediately. Do not
repair.
Never leave pressurized air in the air tank when
performing maintenance.
Never leave the air compressor unattended with the
power supply in use and the air hose connected.
WARNING
EXPLOSION

AIR COMPRESSOR
Improper care could lead to the air tank bursting or
exploding.
Drain air tank daily or after each use to prevent
moisture buildup in the air tank.
Rust can weaken the air tank and cause leaks or
bursting. If rust is detected, replace tank
immediately. Do not try to repair the air tank by
welding, drilling or modifying it in any other way.
These modifications can weaken the air tank and
cause a hazardous condition.
If air tank develops a leak, replace the air tank
immediately. ever repair, weld or make
modifications to the air tank or its attachments.
ever make adjustments to the factory-set
pressures.
ever exceed manufacturer's maximum-allowable
pressure rating attachments.
Because of extreme heat, do not use plastic pipe or
lead tin solder joints for a discharge line.
WARNING
EXPLOSIO
Use caution to minimize risk of fire or explosion.
It is normal for the air compressor motor and
pressure switch to produce sparks while operating. If
sparks come in contact with vapors from gasoline or
solvents, they may ignite and cause a fire or
explosion.
Abrasive tools such as grinders, drills and other
tools are capable of making sparks that can ignite
flammable materials.
Always operate the air compressor a safe distance
away from flammable items. Use in well-ventilated
areas.
ever exceed the maximum rated pressure.
FIRE
WARNING
EXPLOSIO
Use caution when using extension cords.
Use an extension cord which is no more than
25 feet long and at least 14 gauge.
Using an excessively long or thin-wired extension
cord will cause severe damage to the motor.
Use only a 3-wire extension cord that has a 3-blade
grounding plug.

Inspect for Damage
Before using the air compressor, make sure the air tank is not
damaged, inspect all parts for damage, and check that all pipes
are firmly connected.
Do not use the air compressor if any damage is found. If
damaged, have an authorized service center inspect and test the
air compressor to ensure that is working properly.
Save Packaging
IMPORTA T: Save all outside packaging in case you ever need
to return the product for service or repair.
Compressor Location
Use on Flat Surface
For proper operation, the air compressor must be placed on a flat
surface with an incline no greater than 15 degrees.
Maintain a Clear Area
It is very important that the air compressor is positioned so that
there is adequate airflow around the machine. There must be at
least 2 feet of obstaclefree space surrounding and above the air
compressor.
Use in Areas with Clean Air
For proper operation and to maximize the longevity of the air
compressor, it is very important that the air drawn into the air
compressor is clean. The air compressor should not be used in
areas where dust or particulates are in the air. This will damage
the motor and impair proper operation.
IMPO TANT: Always use the air filter, properly installed.
Use caution to minimize risk of fire or explosion.

Electrical Power
Electrical Power equirements
Before using the air compressor, refer to the serial label for
voltage and amperage requirements. Make sure you have a
sufficient electrical supply for supporting the motor's
requirements.
Use a dedicated circuit for the best results.
Low voltage and/or an overload circuit can cause the motor's
overload protection system circuit breaker to trip.
Electrical Extension Cords
Inspect all electrical extension cords to ensure that they are
free of damage.
When using an extension cord, use a heavyduty cord that is
no more than 25 feet long and at least 14 gauge.
Use only a 3wire extension cord that has a 3blade grounding
plug.
OPERATI G THE AIR
COMPRESSOR
Save this manual for future reference.
Introduction
This air compressor features a compact structure, stable
performance, a high airflow rate, and easy operation and
maintenance. Because the air compressor produces no oil in
the airflow, it can be used as an independent air supply
machine for situations in which oil in the airflow is an issue.
The motor directly drives the eccentric wheelconnecting bar
system, making the piston move reciprocally. The piston is
made from a hightemperatureresistant and abrasionresistant
nonmetallic material, and is able to function without lubrication
for a long time.
Assembly
1. Connect your air supply hose to the quickconnect coupling.
2. Make sure the drainage valve is off and that the pressure
switch is in the OFF position.
3. Ensure that the power supply you are going to use is operating
normally.
4. Insert the power supply cord into the power supply socket.
DANGER
There is a danger of electric shock.
Use only undamaged electrical cords.
DO NOT touch bare wires or receptacles.
DO NOT operate air compressor in wet weather or in
wet conditions.
DO NOT touch air compressor or cords if hands or
feet are wet.
Ensure that all cords are free of damage before
connecting to the power supply.
Ensure that you have a sufficient electrical supply for
supporting the requirements of the motor.
HOCK
Use caution when using extension cords.
Use an extension cord which is no more than
25 feet long and at least 14 gauge.
Using an excessively long or thin-wired extension
cord will cause severe damage to the motor.
Use only a 3-wire extension cord that has a 3-blade
grounding plug.
