Operating the Torque Machine
1. By pushing down on the remote control button in the advance position, the rear of the tool will be pushed back
until the reaction arm makes contact with its reaction point.
2. Continue to hold down the button as the socket turns until you hear an audible “click” which will signify the
hydraulic cylinder inside the tool is fully extended and will not turn the socket further.
3. Continuing to hold down the remote control button will result in a rapid buildup of pressure to the point of where
the gauge reads what was preset prior to applying the wrench.
IMPORTANT: The reading of full preset pressure after the cylinder is extended DOES NOT
INDICATE that this pressure (torque) is applied to the bolt. It only indicates that the cylinder is fully
extended and cannot turn the socket further until the tool automatically resets itself.
Releasing the remote control button will retract the cylinder. The tool will automatically reset itself and the operator
will hear an audible “click” indicating he can again push the remote control button and the socket will turn. Each
time the cylinder is extended and retracted, it is called a cycle. Successive cycles are made until the tool “stalls” at
the pre-set Torque/PSI with an accuracy of ±3% and ±1%. Repeatability is +1 -1%.
IMPORTANT: ALWAYS ATTEMPT ONE FINAL CYCLE TO INSURE THE
“STALL” POINT HAS BEEN
REACHED.

Loosening Procedures
First, set the pump to 10,000 PSI. Change the drive and the reaction arm to the loosening mode, assuring the
reaction arm abuts squarely off a solid reaction point. Press and hold the remote control button down. Pressure will
decrease as the socket begins to turn. As the cylinder extends fully, you will hear an audible “click”. Release the
remote control button, and the cylinder automatically retracts, at which time you again hear the audible “click”.
Repeat this process until the fastener can be removed by hand.
NOTE: IF THE BOLT DOES NOT LOOSEN WITH THE ABOVE PROCEDURE, IT IS AN INDICATION
THAT YOU REQUIRE THE NEXT LARGER SIZE TOOL TO LOOSEN THE BOLT.
