Remedy
•
Replace the hose. See Drawings.

connect the Pressure and Tank lines. See

•
Make sure the hydraulic power unit is shut down.

Adjust the pipe stop index and the wrenches to the
OD tool joint size. See Operation.
•
If the dies still slip on the pipe while torquing, the
throat of the hook could be contacting the body of
the pipe ( this can occur especially running tool joints
larger than 7" ). This problem can be solved by
gripping the Hawkjaw on the pipe and looking to
see if the throat of the hook is contacting the pipe
body. If the hook is contacting the pipe body while
gripping (not torquing), then the wrench adjust nut
needs to be adjusted slightly smaller to get hook
throat stand-off.
•
The dies are worn out. Replace the dies. See
Maintenance & Repair.
•
There is a Grip cylinder piston leak. See Trouble
Shooting.
•
For break out, if the drill pipe connection is not
broken, the spinner is unable to spin the drill pipe.
Break out the connection, and spin again. See
Operation.
