Using this Topeak floor pump is a piece of cake. First, choose the right valve head (Presta, Schrader, or Dunlop) on the TwinHead® DX. Attach it firmly to your tire valve. Then, hold the padded handle and start pumping. The ergonomic handle makes it comfortable to use. Keep an eye on the 3 - inch gauge to reach the desired pressure. When you're done, carefully remove the pump head from the valve. As for maintenance, keep the pump clean after use. Wipe off any dirt or debris from the barrel, base, and handle. If the hose gets dirty, you can wash it gently with mild soap and water. Store the pump in a dry place to prevent rusting. Also, check the ball / bladder heads regularly to make sure they're in good condition for inflating balls or bladders.
