Installation
Hydraulic system requirements
The following is required for an optimum performance of the hydraulic rotary hammer drill:
Provide a volume flow of 4 – 6.6 gallons/ min at an operating pressure of 1160 – 2030 PSI.
The system should not have more than 247 PSI back pressure.
The hydraulic system should have sufficient heat rejection capacity to limit the maximum oil temperature
to 140 °F at the maximum expected ambient temperature.
It is recommended:
That filter elements are sized for a volume flow of at least 30 gallons/ min for cold temperature startup
a
nd 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 rotary hammer drill
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 0.472 to 0.629 inches for the inner diameter and between 590 and
1181 inches for the length. Always connect the return hose first and disconnect it at last (see fig. 2).
