Flat tires are a fact of life in bicycling. Spend enough time on the saddle and turning the cranks, and soon enough an inner tube goes flat. This requires a repair and inner tube inflation. Blackburn bicycle pumps fit the bill for inflating bicycle inner tubes. Blackburn pumps have multi-valve nozzles that can be used with both Schrader and Presta inner tube valves.
Push the Blackburn pump head lever up so it is perpendicular to the pump barrel. Unscrew the inner tube's valve cap.
Push the pump head onto the inner tube valve. Turn the selector dial on the pump to either the Schrader or Presta valve setting. Flip the pump lever back down to lock the pump onto the valve.
Pull the pump handle out from the barrel, then pull and push the handle to pump the inner tube full of air. Flip the pump handle lock back up and pull the pump head off the valve.
Turn the dial on the pump head to either the Schrader or Presta valve setting, depending on the valve type of the inner tube being inflated. Unscrew the valve cap from the inner tube on the bicycle wheel.
Flip up the pump head lever and press the pump head onto the inner tube's valve. Flip the lever back down to lock the pump head onto the valve. Pull up on the pump handle and push and pull until the tire is inflated.
Flip the pump head lever back up and pull it off the inner tube valve.
