Low Torque Warning Test

Operation30

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.
