HYDRAULIC CONNECTIONS
A pair of hydraulic lines - a 1” supply line and a 1-1/4” return line - connect the tong to the power unit (see illustration below). Ancillary
devices (hydraulic motors, hydraulic cylinders, etc.) are connected through the valve block.
Perform any hydraulic connection when the power unit is not running, or when the hydraulic pump is disengaged. The possibility of error
in inter-changing the high pressure supply hose and the low pressure return hose has been eliminated, because the supply side coupling
is smaller than the return side.
