Principle Of Operation - Gage Bilt GB713SR-5 Original Instructions Manual

Table of Contents

When the lever assembly is depressed, the pressurized air inside of the tool is released allowing spring pressure to move the valve

spool assembly causing the air to be redirected. The air is directed to the top of the air piston assembly, moving it in a downward

direction. The air below the air piston assembly is then directed through the valve sleeve and exhausted out of the bottom of the tool.

Simultaneously, the piston rod assembly connected to the air piston assembly is also moving down, forcing hydraulic oil up and into

the front side of the head cylinder, causing the piston to move to the rear of the head cylinder. The internal components of the attached

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

assembly is released. Air pressure is then built up inside of the handle assembly causing the valve spool assembly to return to its

original position and reversing the sequence, allowing air to return to the rear of the piston, moving the piston to the forward position.
