Important Operating Instructions

6. SAFETY RELIEF VALVE: 

This compressor is equipped with a safety relief valve that is

designed to prevent system failures by relieving pressure from the system when the air pressure
reaches a predetermined level. The safety relief valve is preset by the manufacturer. 

DO NOT

attempt to modify or remove the safety relief valve.

7. AIR TANK DRAIN VALVE: 

Moisture is produced whenever air is compressed. It is critical to

drain water from the air tank on this compressor frequently. If unit is used only occasionally, tank
should be drained after each use and prior to the next use. To drain the tank, slowly open the tank
drain fitting by turning counterclockwise Once all moisture has drained out, close the fitting
securely. 

NOTE: 

Air tank will not pressurize while drain valve is open.

NOTE: 

A dirty air filter will reduce air compressor performance and can lead to product failure.

8. MANUAL THERMAL OVERLOAD SWITCH: 

The electric motor has a manual thermal overload

protector. If the motor overheats for any reason, the thermal overload protector will shut off the
motor. Turn pressure switch to the OFF position and wait for unit to cool before pushing the reset
button and restarting the compressor. 

NOTICE: 

This air compressor is designed for household

use only and is not intended to operate heavy-duty air tools. If your application’s demands exceed
the capacity of this air compressor, a larger air compressor that is matched to your application is
recommended. If the unit shuts down again, please call the customer service center for additional
assistance.

9. AIR INTAKE FILTER: 

This compressor is equipped with an externally accessible air intake

filter that is designed to clean air coming into the pump. The filter

element is easily removed for periodic cleaning. Use compressed air to blow loose dirt and debris
from the paper filter element and reinstall. Replace filter element when necessary.

10. HANDLE: 

Convenient handle for easy transport.

OPERATING

INITIAL SET-UP/BREAK-IN PROCEDURE:

Caution: 

Do not attach air hose, air tools, or other accessories to the air outlet until break-in

procedure has been successfully completed.

1.

 Read and understand the entire instruction manual, including all safety warnings before setting

up air compressor.

2.

 Place air compressor on a flat, level surface.
