• Do not cut, weld or otherwise modify reaction arms or sockets.
• Do not expose reaction arms or sockets to extremely high or low temperatures.
• Do not leave tools with reaction arms and sockets hanging on the nut or the bolt.
• Do not use pump units, hydraulic hoses, hose connections with hose couplings, power
cables or remote control cables to carry or move the equipment. Always hold the
pump unit or the tool to carry or move the equipment.
• Store tools and accessories which are not in use properly.
2.2 Additional safety instructions
2.2.1 Electric and pneumatic pump units
• Only use HYTORC pump units.
• Do not modify the pump unit in any way.
• Do not use the electric pump unit in atmospheres which are potentially volatile. If there
is doubt, use a pneumatic pump unit. 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
dB.
• 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).
• Make sure that the pump unit is properly grounded.
• Make sure that the pump unit is filled with the (supplied) hydraulic oil (Shell Tellus S2
V32).
• Make sure that the oil level in the oil tank is beween the minimum mark and the
maximum mark. Use the oil level sight glasses to check the oil level.
• To refill the oil tank with hydraulic oil, use only high-grade hydraulic oil (ISO VG 32 or
ISO VG 46 in more extreme conditions).
• Do not mix different grades of hydraulic oil.
• Make sure that the oil filler cap is placed on the oil filling point.
2.2.2 Electric pump units
• Make sure that the mains voltage corresponds to the rated voltage of the pump unit.
• For 230V pump units, the mains voltage must be between 200V and 230V.
• For 400V pump units, the mains voltage must be between 380V and 460V.
• If you use an extension cable:
• Do not use an extension cable longer than necessary.
• Make sure that the length of the extension cable does not exceed 50 metres.
• Make sure that the cross section of the wires in the extension cable is at least 2.5
mm
2
.
• Fully unroll the extension cable from the cable drum.
• Make sure that there is no overvoltage or undervoltage. Do not use extension cables
that are too thin or too long.
• If you use a 400V pump unit, make sure that the direction of rotation is correct. When
the LED indicator becomes red, the direction of rotation is incorrect. Reverse the
polarity of the phase inverter plug.
2.2.3 Hydraulic hoses
• Only use HYTORC hydraulic hoses.
• Do not modify the hydraulic hoses in any way.
