Connecting the hydraulic supply to the hydraulic rotary hammer drill
The machine is designed for an open circuit.
A safety block has to be used at a pressure of more than 80 bar.
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).
