Puma Compressor

[NE1]

Can anybody tell me what the little Red lever does or doesn't do on my Compressor .

Should it be in the up position as shown or down .

[Will B Good]

Unloader bypass maybe.....??

[fredwiggy]

For auto mode or pressure switch perhaps?

It's a shut off switch.....  start it and then flip the lever. The compressor should stop.

Pressure Switch Function:

The pressure switch monitors the air pressure within the compressor's tank. It's designed to maintain a consistent pressure range by automatically starting the compressor when the pressure drops below a certain point and stopping it when the pressure reaches a preset maximum. 

Manual On/Off:

The red lever usually has an "ON/OFF" or "AUTO" setting. In the "ON" position, it allows the compressor to run automatically based on the pressure switch. In the "OFF" position, it stops the compressor from running, even if the pressure drops. 

Manual Cut-Off:

The lever also provides a manual way to shut off the compressor, which is useful for maintenance, or when the compressor is not in use. 

Auto-Off Disconnect:

Some pressure switches with a red lever also include an auto-off feature that disconnects the compressor from the power source when the lever is in the "OFF" position, providing an extra layer of safety.
