AIR  COMPRESSOR

Electrical Power

Electrical Power Requirements

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.  

OPERATING 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.

SHOCK

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.

CAUTION
