Making-Up a Connection
Place the tool into a suitable vise with the connection as close to the vise as possible. Make
up the tool by hand as tight as possible. Place the tong as close to the connection as possible.
Move the Tong Jack into position and connect the tong to the Tong Jack. Connect the air
supply to the Tong Jack. Lower the arm as far as possible. With the arm fully lowered,
adjust the pressure control to provide the required torque.
WARNING: Under no circumstances should the maximum working load of the
tong or vise be exceeded. The tong jack may be capable of providing more force
than the tong is rated for.
Lift the arm to apply force to the tong. If the tong arm reaches the end of its travel, lower the
arm, insure that the tong is still properly latched, and raise the arm again. Continue raising
the arm until the arm stops moving. The tool will then be full made up. Lower the arm and
unlatch the tong.
Breaking-Out a Connection
Place the tool into a suitable vise with the connection as close to the vise as possible. Place
the tong as close to the connection as possible. Move the Tong Jack into position and
connect the tong to the Tong Jack. Connect the air supply to the Tong Jack. Lower the arm
as far as possible. With the arm fully lowered, adjust the pressure control fully counter-
clockwise to achieve the minimum pressure possible. Raise the tong until the arm stops
moving. Continue lifting on the tong handle while SLOWLY increasing the pressure until
the connection breaks. Do not adjust the pressure higher than the rating of the tong or vise.
If the connection does not break before reaching the rating of the tong, vise, or maximum
pressure of the Tong Jack, stop the operation and use a safe method of producing higher
torque. Should you need assistance, please contact GEARENCH™ for help in selecting
appropriate equipment.
WARNING: Under no circumstances should the maximum working load of the
tong or vise be exceeded. The tong jack may be capable of providing more force
than the tong is rated for.
Lower the arm and unlatch the tong.
