Press down hard so that the Shoe (28) is firmly contacting the floor, and then strike the Hammer Face (10) with the Hammer (49) to drive out a staple. Lift the tool off of the floor.

4.Repeat the process until you are finished. Then, disconnect the Floor Stapler from the air source.

Warning! After disconnecting the Stapler from the air compressor, there could still be enough air pressure to fire the Stapler. After the air compressor hose is disconnected, always fire the Stapler repeatedly to make sure all of the air is expended
