Determine which hydraulic valve to replace. Make
sure the air hoses are connected to the hydraulic
valves V1 and V2. Place your fingers over the
small vent where the valve body joins with the
aluminum end cap on one end of the hydraulic
valves V1 and V2 at Port A. Push in Grip, and
press Torque. Your finger should feel a blast of air
at each vent. If no air comes out of the air vent on
the hydraulic valve V1 and/or V2, replace the
hydraulic valve. See Drawings, p. 114, 128.

Adjust the wrenches and the pipe stop index to the
OD tool joint size. See Operate, p. 18, 24.

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.
z
The dies are worn out. Replace the dies. See
Maintenance & Repair, p. 37-43.

There is a Grip cylinder piston leak. See Trouble
Shooting, p. 89.

The Grip button is being released before the
Torque button is released. Release both the Torque
and Grip button at the same time. See Operate, p. 23.
z
Release both the Torque and Grip button at the
same time. If there is a delay in releasing the Grip
button, the Torque cylinder will retract while the dies
are still gripped on the pipe.

Turn the Selector switch to Make for make up or
Break for break out. See Operation, p. 28, 23.
