Page 8: Safety
Only use the tools for the purposes for which they have been designed. Do not force small tools or accessories to do the job of a larger tool. HYTORC can develop customized accessories to ensure safe and simple operation. Contact your local HYTORC representative for more information. -
Page 9: Additional Safety Instructions
Metal-to-metal contact can cause sparks. Take appropriate additional measures. • Wear hearing protection. The sound emission of HYTORC pump units is less than 80 • Make sure that the maximum operating pressure of the pump unit is not higher than the maximum permitted pressure of 700 bar (10,000 psi). -
Page 10: Reaction Arms
Replace damaged hydraulic hoses immediately. Replace the hydraulic hoses at least every three years. 2.2.4 Reaction arms • Only use HYTORC reaction arms. • Do not modify the reaction arms in any way. • Place the reaction arm against a solid reaction point that can handle the load. -

Page 19: Installation
Installation Installation Hydraulic hoses The working pressure of the hydraulic hoses is up to 700 bar. The safety factor of the hydraulic hoses is factor 4. 4.1.1 Hydraulic hose connections Use a twin hose to connect the pump unit to the tool. A twin hose consists of two hoses. The supply hose has two ends with female couplings. -
Page 20: Connecting The Hydraulic Hoses
Loosen the locking ring of the female coupling from the male coupling and pull the couplings apart. Toothed screw-type safety couplings (HYTORC 716) The coupling is identical to the screw-type safe- ty couplings (type Pioneer), but both coupling are toothed. -
Page 21: Disconnecting The Hydraulic Hoses
Installation • Make sure that the hydraulic hoses are securely connected to both the pump unit and the tool. Make sure that there is no clearance between the male couplings and the female couplings. If the hydraulic hoses become loose, no hydraulic oil will flow through the hoses and the tool will not operate. -
