Making A Connection

a) Ensure hydraulic power supply to the tong is energized. The master link on the rigid sling must be used to suspend the tong.
Do not suspend the tong directly from the rigid sling.
b) Ensure the backing pin is in the "make-up" position. From the front of the tong, the backing pin correctly configured for makeup
will be in the 10 o'clock position (see Illustration 2.H.2 next page). If it is not, simply lift up and place in the correct position (see
Illustration 2 next page). The cage plate opening must be aligned with the door opening when setting the backing pin position.
