PRINCIPLE OF OPERATION

Incoming air is regulated between 80-100psi. (5.5-6.9 bar) through the air filter / regulator. When the actuator lever assembly is depressed on the

installation tool, pressurized air inside the four-way valve is released allowing a plunger to unseat a valve ball allowing the air to be

redirected to the rear of the booster starting the cycle. As the air piston in the booster begins to move forward the air in the front side is

being exhausted out of the muffler and simultaneously forcing hydraulic oil up and into the front side of the head cylinder assembly,

causing the head piston to move to the rear of the head cylinder assembly. The internal components of the attached nose assembly are

also moving with the head piston to start the fastener installation. When the fastener installation is completed, the actuator lever assembly is

released. Air pressure is then built up inside of the four-way valve re-seating the valve ball that in return directs the air to the front

side of the booster and to the rear of the head cylinder reversing the sequence.
