Air Compressor

BEFORE EACH USE

 

WARNING

•  Risk of unsafe operation. Firmly grasp air hose in hand when installing or disconnecting to prevent hose 

whip.

•  Risk of unsafe operation. Do not use damaged or worn accessories.
• 

Risk of bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s 

maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed 

the maximum pressure rating.

DUTY CYCLE: This air compressor pump is capable of running continuously. To prolong the life of your 

air compressor, it is recommended that a 50%-75% average duty cycle be maintained; that is, the air 

compressor pump should not run more than 30-45 minutes in any given hour.

ACCESSORIES

Accessories for this unit are sold separately.

Attaching an air hose

Your air compressor is supplied with a 1/4" push-connect air coupler (fig.3) . With a factory-installed air 

coupler, your compressor is ready to accept air hoses 

equipped with 1/4" male air connectors (fig 4).

Use only air hoses rated for use with 

150 psi air pressure or higher.

To install any air hose equipped with a 1/4" male 

connector (fig 4)

:

1. 

Simply push the "connector" or "plug" into the 

fitting and it automatically engages.

2.  Verify that air hose is securely connected to air 

coupler by pulling on the air hose.

OPERATING INSTRUCTIONS
