10. To remove hose from the hose bracket, simply press down on the hose clamp release 
tab to release bracket clamp.

11. Tie compressor’s positive lead wires together and connect to pressure switch lead.

12. Make sure that your compressor setup is properly fused. Dual 325C compressors 
pull approximately 40 maximum amps of power.

13. Always locate fuse as close as possible to power source.

14. Before connecting to power source, check to make sure that all connections are 
made properly.

15. Connect and test compressor system by running the compressor for a short time to 
build up pressure in your air tank.

16. Once air pressure reaches preset cut out pressure of your pressure switch, the 
compressor will shut off. Inspect all air line connections for leaks with soap and 
water solution. If a leak is detected, the air line may not be cut squarely or pushed all 
the way in. Tighten connections if needed.

COMPRESSOR OPERATING INSTRUCTIONS

IMPORTANT: The compressors have a maximum working pressure of 150 PSI. Always 
operate the compressor at or below the MAXIMUM PRESSURE RATING of the 
compressor. Operation exceeding maximum pressure ratings and or duty cycle will 
result in damage to air compressor.

1. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR. 
This feature is designed to protect the air compressor from overheating and causing 
permanent damage to your air compressor. The thermal overload protector will 
automatically cut off power to your air compressor should the internal operating 
temperature of the air compressor rise above safe levels during excessive use.

2. Should at any time during use, your air compressor automatically shuts of – do not 
attempt to restart the air compressor. Turn power switch to the air compressor to the 
OFF position. The automatic thermal overload protector will automatically reset when 
internal temperature of the air compressor drops below safe level. After allowing air 
compressor to cool off for about 30 minutes, you can safely resume use of the air 
compressor by turning on the air compressor.

3. To prevent discharge of your vehicle’s battery and to provide peak performance, we 
strongly recommend that you keep the vehicle’s engine running while using the air 
compressor.

4. ONLY OPERATE AIR COMPRESSORS IN WELL VENTILATED AREAS.
