Check that air is reaching the Torque hydraulic

power unit is shut down. Disconnect the air
supply to the HawkJaw. Disconnect the grey

holding down the collet ring, pull out the grey air hose.
Place your hand over the disconnected Torque air
hose.
Connect the air supply to the

of the hose. If no air comes out of a hose, the air
hoses are improperly connected within the Left
and Right control handles. See Drawings, p. 110, 112.
