Hydraulic system requirements
The following is required for an optimum performance of the hydraulic impact wrench:
• Provide a volume flow of 25 to 45 l/min at an operating pressure of 90 to140 bar.
• The system should not have more than 17 bar back pressure.
• The hydraulic system should have sufficient heat rejection capacity to limit the maximum oil
temperature to 60° C at the maximum expected ambient temperature.
It is recommended:
• That filter elements are sized for a volume flow of at least 114 lpm for cold temperature startup and for
maximum dirt holding capacity.
• The hydraulic system should have a minimum of 10 to 25 micron of full-flow filtration.
Connecting the hydraulic supply to the hydraulic impact wrench
The machine is designed for an open circuit.
Check:
• The circuit type (open circuit or closed circuit), before connecting the machine.
• That all hose couplings are clean, before connecting the hoses.
• That there are no signs of leakage.
• That the machine is clean and dry.
• That all assembly parts and fixing elements are firmly fixed, respectively tight.
The recommended hose size is from 12 mm to 16 mm for the inner diameter and between 15
and 30 m for the length. Always connect the return hose first and disconnect it at last (see fig.
2).
