Craftsman 919.166442 owner manual How to Stop, Before Starting, Before Each Start-Up

Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.

Check Valve:
When the air
compressor is
operating, the
check valve
is "open",
allowing
compressed
air to enter	Check Valve
the air tank.
When the

air compressor reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain inside the air tank.

How to Use Your Unit

How to Stop:

1.Set the On/Auto/Off lever to "Off".

Before Starting

Break-in instructions

Risk of Unsafe Operation. Serious

damage may result if the following break-in instructions are not closely followed.

This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced.

1.Make sure the On/Auto/Off lever is in the "Off" position.

NOTE: If quick connect is installed, pull coupler back until it clicks to prevent air from escaping through the quick connect.

2.Plug the power cord into the correct branch circuit receptacle. (Refer to "Voltage and Circuit Protection" paragraph in the Installation section of this manual.)

3.Open the drain valve fully (counter-clockwise) to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

4.Move the On/Auto/Off lever to "On/Auto" position. The compressor will start.

5.Run the compressor for 15 minutes. Make sure the drain valve is open and there is minimal air pressure build-up in tank.

6.After 15 minutes, close the drain valve (clockwise). The air receiver will fill to "cut-out" pressure and the motor will stop.

The compressor is now ready for use.

Before Each Start-Up:

1.Place On/Auto/Off lever to "Off".

2.Pull regulator knob out, turn counter-clockwise until it stops. Push knob in to lock in place.

3.Attach hose and accessories. NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect.

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.
