All fittings will then be hand tight again. Newer style pumps (HYTORC 115, HYTORC 230, HYTORC AIR) are equipped with an auto-pressure relief. Never disconnect or connect any hydraulic hoses or fittings without first unloading the wrench and the pump. -
Page 8: Electrical Connections
Electrical Connections Ensure proper power availability to prevent motor failure or dangerous electrical overloading. Compare the motor nameplate for required amperage. Do not use electric pump if the 3-prong electrical plug is not whole. Minimize the length of extension cords and be sure they are of adequate wire size, with ground connections. Extension cord should be #10 AWG gauge. -
Page 9: Operation
General All HYTORC Torque Machines are supplied completely assembled, ready for use. A HYTORC Hydraulic Power Pack, for use with your HYTORC machine, is recommended to provide the speed, pressure and portability that makes your HYTORC System efficient and accurate. -
Page 10: Drive Direction Change
Reaction Arm All HYTORC Torque machines are equipped with a universal reaction arm. These reaction arms are employed to absorb and counteract forces created as the unit operates. The reaction arm should extend in the same direction of the square drive;... -
Page 11: Setting Torque
Setting Torque Once the system is fully connected and the proper power supply available, it is time to adjust the pump pressure to the level needed on your job. When tightening, use the manufacturer’s specifications to determine the torque value which you will ultimately require. - Page 12 Setting the Pressure on the Pump To set the pressure on the pump, follow this procedure: 1. Loosen the knurled locking ring below the “T” handle on the pump’s external pressure regulator. Then tum the “T” handle (shown in figure 6) counterclockwise (CCW) until it turns freely and easily. 2.

Page 13: Operating The Torque Machine
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 its reaction arm will contact 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 tum the socket further. -
Page 14: Hytorc Power Packs
POWER PACKS General Information All HYTORC Power Packs operate at a pressure range from 500 to 10,000 PSI and are fully adjustable. They have been engineered and designed for portability and high flow for increased speed. Before using your HYTORC power pack, check the following points: •... -
Page 15: Operation
NOTE: Read the section labeled HYTORC OPERATIONS and SETTING TORQUE prior to installing the torque wrench onto the application. Your HYTORC 115/230 hydraulic pump has been designed with an auto shut off system. The pump will shut off after approximately 30 seconds of non-cycling. This will prevent overheating and unnecessary wear which will prolong the life of your pump. -
Page 16: Preventive Maintenance
Failure of structural members of the tool are quite rare, but replacement parts are available from stock. All repairs to HYTORC tools may be made by reasonably experienced individuals according to the aforementioned instructions. -
Page 17: Preventive Maintenance - Hydraulic Power Packs
Preventive Maintenance - Hydraulic Power Packs HYTORC Hydraulic Power Packs are precision-built units and, as such, do require a certain amount of care and maintenance. • Hydraulic Oil Oil should be completely changed after every 40 hours of operation, or at least twice a year. Always make sure the reservoir is filled with fluid. -

SECTION VI TROUBLESHOOTING SYMPTOM PROBABLE CAUSE REQUIRED ACTION Gauge shows pressure build-up but the 1. Couplings loose or inoperative 1. Tighten and/or replace couplings. Use Test #1 tool will not cycle listed below to isolate problem. 2. Solenoid inoperative 2. Check using test #2 below. If solenoid is bad, replace. - Page 19 1. Run test #5. Replumb system as necessary. 2. Multiple hoses in even numbers 2. As plumbed, HYTORC hoses may only be joined together in odd numbers ONLY. If it is nec- essary to use 2,4,6 hoses - make un adapter from spare high pressure couplings and nipples.
- Page 20 SYMPTOM PROBABLE CAUSE REQUIRED ACTION Gauge records no pressure 1. Gauge connection is loose l. Tighten coupling. 2. Bad gauge 2. Replace gauge 3. Pump will not build pressure 3. See cylinder pressure will not build pressure- above 4. Tool seals are blown 4.
- Page 21 Continue to tighten until the flow stops plus a quarter turn. TEST #5 THIS TEST SHOULD BE RUN PRIOR TO EVERY USE OF A HYTORC TOOL Connect the tool, pump and hoses together as normal. Cycle the pump several times. Cycle the system once more and observe the sequence of operation.

Page 31: C Square/Allen Drive Working Torque
SQUARE/ALLEN DRIVE WORKING TORQUE DRIVE SIZE: The square or hex drive of each HYTORC is limited in its maximum output by its material and its engagement area. Since your HYTORC uses a specially suited alloy-steel for its drive members, the following maximum torque output can be achieved without drive failure, provided the reaction member abuts close to the same plane as the nut to be turned. - Page 32 Being #1..is no coincidence!
