Low Torque Warning Test
Operation 30
Test#1: Hawk strongly recom-
mends 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 as shown. 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 page 96.
LOW TORQUE WARNING SYS-
TEM CHECK
Do not make up pipe with the low
torque warning test connector
dis-connected. This may result in
under torqued pipe in the hole.
WARNING
NOTE
For safety, push in the "E"
stop when the HawkJaw is at
rest.
CHECK
If the Torque cylinder strokes out
before the desired torque is reached,
the Torque gauge needle (TN) will
fall off to approximately a 8000 Ft.-
Lb. reading. If this happens, release
Torque (T). Immediately release
Grip (G). Wait for the Torque
cylinder to reset.

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 ap-
proximately an 8000 Ft.- Lb reading.
If this does not occur, see Trouble-
shooting p. 96.
