INSTALLATION
A, Hanging: Connect lift with tong hanging rod and hang the tong on the derrick of workover rig, the hanging point is 15 m above ground and the hanging should be in free condition. The distance between the tong center and the center of the well is recommended to be 0.5m. The hanging height is proper when the backup tong could rightly grip the tubing collar.
B, Level: Adjust the screw (Z6-58)on the tong hanger to level the tong and backup, this should be done to ensure proper gripping of the jaws.
C, Back guy: Tie one end of back guy on derrick and the other end on back guide seat of power tong, back guy should be capable of bearing a load of 20 KN, when power tong is in make up position, the back guy should be at right angle to the tong and on the opposite side of operator who operates the control handles, this insures a safe operation.
D, Pressure hoses: Connect hoses from the hydraulic power source to the control valve bank of the power tong. The inlet and the outlet hoses can't be misconnected.
