ATING INSTRUCTIONS

 

 

 

 

 

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. 

 

 

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.    

 

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.

exposed to voltage sources or compressed air. Disconnect power source from the compressor and bleed off all 
air pressure.

5.

The compressor is ready for use.

How to shut down
