Connect spring hanger (or lifting hydraulic cylinder) with hanging rod of master tong and hoist the
tubing power tong on the derrick of workover rig. The suspension point shall be more than 15m
from the wellhead. The center of tong head should be about 0.7m far away from wellhead under
free suspension state. The suspension height is proper if the back-up tong just can grip tool joint or
the coupling of tubing or casing. Refer to Fig.1.

4.4
Installation of jaw plate
Select proper jaws based on the pipe to handle. During the installation, always make sure the
opening of brake disc and notched gear is consistent. In this way, the pulling rod is at the back side,
which will facilitate the installation of jaws. Pay attention to the right and left direction during the
installation process, refer to Fig.5. Add lubricating grease to jaw pins and fix them with cotter pins.
Refer to Table 1 for jaw specification details.
4.5
Connection of hydraulic pipeline
Prior to starting the hydraulic power station, connect the high pressure hose and oil return hose to
the power tong and hydraulic power unit.
4.6
Additional information
It is necessary to remove front tong feet before operating the tong, and loosen the nuts below the
connection. Refer to Fig.4.
