Operation
The operating controls of the PETOL™ Tong Jack are shown in the figure below. The
pressure gauge is used to monitor and adjust the operating pressure. The pressure to force
conversion chart is used to determine the actual force in pounds being applied to the tong.
The air connection supplies the compressed air to the unit. The pressure control regulates the
output pressure and adjusts the force produced. Turning the knob clockwise increases the
pressure. Turning the knob counter-clockwise reduces the pressure. The direction control
causes the arm to raise or lower. Lift the control to raise the arm, lower the control to lower
the arm. The tong connection pin connects to the tong handle. If the tong has a clevis on the
handle, use the “y” shaped link shown in the diagram. If the tong has a single handle loop,
use two flat plate links in place of the “y” link.
