Simply attach its supplied heavy duty battery clamp power leads to the battery, and attach the lever style air chuck to a tire valve stem and turn the unit on, it can inflate up to 37 inch tires. Air pressure can be monitored using the 5-in-1 inline inflator/deflator hose and gauge included. Always turn off the unit to take an accurate pressure reading since air flow into the tire will show an inaccurate pressure reading while the unit is running.

About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.
