How do I use the built-in compressor on my Stanley FatMax jump starter?

Ensure the jump-starter is turned off, then connect the compressor hose to the unit's air outlet and attach the Sure Fit® nozzle to the tire or inflatable's valve stem. Turn on the compressor by pressing the compressor power switch and monitor the built-in pressure gauge to reach your desired pressure. Once achieved, turn off the compressor and remove the nozzle.
