Using the Milwaukee M12 2475 - 21XC Compact Inflator is a breeze. First, make sure the 48 - 11 - 2440 M12 XC REDLITHIUM 4.0 Battery Pack is fully charged with the 48 - 59 - 2401 M12 Lithium - ion Battery Charger. Then, connect the appropriate chuck (Schrader or Presta) to the tire valve. Set your desired pressure on the illuminated digital gauge. Start the inflator, and the TrueFill™ Auto shut - off technology will stop it once the target pressure is reached. When inflating balls, use the ball inflation needle. Remember to place the inflator on a flat surface, as the anti - vibration feet work best this way. Keep it in a dry place to avoid weather - related damage. Check the battery regularly and charge it when it's low. Also, inspect the hose and chucks for any signs of wear or damage. If you have any issues, the 3 - year limited warranty has you covered.
