When the actuator assembly (1) (510127) is depressed, the pressurized air inside the tool is directed to the front side of the piston
(3) (510101) thus moving it to the rear of the cylinder assembly (2) (500119), forcing the air from the back side of the piston (3)
(510101) to be exhausted from the standard exhaust port on side of tool (see page 5). The internal components of the attached nose
assembly are simultaneously moving with the piston (3) (510101) to start the fastener installation. When complete, the actuator
assembly (1) (510127) is released directing the air to the back side of the piston (3) (510101) reversing the sequence.
