Connection of Hydraulic Circuits
To connect the attachment hydraulic pipeline,
please operate as per following procedure:
1. Relieve the residual pressure from system
and then close the shutoff valve.
2. Take out the plug.
3. Connect the attachment hydraulic pipes to
ports (a). While installing a hydraulic
breaking hammer, connect the oil inlet port
to port (a).
4. Open the shutoff valve. While installing a
hydraulic breaking hammer, open the
selector valve (1).
5. After connections, fully bleed the air from
hydraulic pipes.
a. Start the engine and run at low idling
speed under no-load condition for
10min.
b. During the running of engine at low
idling speed, operate the hydraulic
auxiliary switch repeatedly (for
approximately 10 times) to bleed the
air from hydraulic pipes.
c. Stop the engine and wait for at least
5min, till the air bubbles overflow
from the hydraulic oil in the oil tank.
Important: If applicable, follow the attachment
manufacturer’s procedure to bleed the air.
6. Check for presence of oil leakage.
Disconnection of Hydraulic Circuits
1. Relieve the residual pressure from system
and then close the shutoff valve.
2. Disconnect the pipelines from ports.
3. Install the plug.
Relieve residual pressure
After using the auxiliary hydraulic circuit,
there is residual pressure in the circuit. This
is called residual pressure. Before
disconnecting the pipeline, release the
residual pressure.
