Hawk Industries Hawkjaw Sr. Manual 100K-2GSR Serial Numbers 121 to 140 - Manual (Page 25)

CHECK
If the Torque cylinder strokes out before the
desired torque is reached, the Torque gauge
needle (TN) will fall off to approxi-
mately a 8000 Ft.-Lb. reading. If this happens,
release Torque (T). Immediately release
Grip (G). Wait for the Torque cylinder to
reset.
LOW TORQUE WARNING
SYSTEM CHECK
Test#1: Hawk strongly recommends
testing the Low Torque Warning System
on every trip. If this test procedure is not
performed, the drill string could be over
torqued.Disconnect the Low torque warning
test connector (LTC) located on the main
hanger. Torque the first connection. Note
the torque gage needle position; keep the
Hawkjaw positioned on the same
connection. Now re-connect the Low
Torque Warning Connector. Re-torque the
connection. The torque gage should
indicate the same reading. If it does not, see
Trouble Shooting.
Test#2: Hawk strongly recommends testing
the Low Torque Warning System on every
trip. If this test procedure is not performed,
the drill string could be under torqued.
When breaking the first connection, push
in the Grip Hold (GH) button, hold down
both Torque (T) and Grip (G) until the
Torque Cylinder fully strokes out. When
the Torque Cylinder fully strokes out, the
Torque Gauge Needle will fall off to
approximately an 8000 Ft.-Lb reading. If
this does not occur, see Trouble Shooting.
