AIR COMPRESSOR 3-GALLON (11.4 L) - 058-8381-8

AIR COMPRESSOR 3-GALLON (11.4 L) - 058-8381-8

Before each start-up

1.

 

Set the power switch (C) to the 

(off)

 

position.

2.

 

Turn the air pressure regulator knob (G) counter-clockwise until it stops.

3.

 

Attach hose and accessories.

 

WARNING!

 

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.

How to start

 

WARNING!

 

If the pump has been transported or turned upside down (even 

partially), allow the pump to sit in a normal, upright position for approximately 10 
minutes before starting.

1.

 

Close the tank drain valve (J).

2.

 

Plug in the power cord (E).

3.

 

Set the power switch (C) to the 

(on) position and allow tank pressure to build. Motor will stop 

when tank pressure reaches “cut-out” pressure.

4.

 

Turn the air pressure regulator knob (G) clockwise until desired pressure is reached.

5.

 

The compressor is ready for use.

 

WARNING!

 

High temperatures are generated by the electric motor and the 

pump. To prevent burns or other injuries, DO NOT touch the air compressor while it is 
running. Allow it to cool before handling or servicing. Keep children away from the air 
compressor at all times.

How to shut down

1.

 

Set the power switch (C) to the 

(off) position.

2.

 

Unplug the power cord (E).

3.

 

Reduce the pressure in the tank through the outlet hose. Pulling the safety valve ring (F) and 
keeping it open will also reduce the pressure in the tank.

 

CAUTION!

 

Escaping air and moisture can propel debris that may cause eye 

injury. Wear safety goggles when opening the drain valve.

 

WARNING!

 To avoid personal injury, always shut off and unplug the unit, and 

relieve all air pressure from the system before performing any service on the air 
compressor.

 

WARNING!

 

Risk of unsafe operation. Unit cycles automatically when power 

is on. When performing maintenance, you may be exposed to voltage sources, 
compressed air or moving parts. Personal injuries can occur. Before performing any 
maintenance or repair, disconnect power source from the compressor and bleed off 
all air pressure.
