MRP Mobile Rotating Pulverizer Operation & Maintenance Manual | 23
HYDRAULIC TEST PORTS
The MRP is equipped with hydraulic test ports that will allow you to measure cylinder pressure for troubleshooting
purposes.
Accessing the Hydraulic Test Ports
Do not connect or disconnect hydraulic lines while
they are pressurized. Escaping fluid under pressure
can penetrate the skin, causing serious injury.
Trapped hydraulic pressure may be present after
the base machine is shut off. Extreme caution must
be taken when removing hydraulic hoses or lines.
Injury or death could result.
1.
Before performing maintenance, place the attachment on flat, hard ground, so that the part being maintained is
closest to the ground and the attachment will not move when hydraulic pressure is released.
2.
Turn off the excavator and relieve any trapped pressure in the hydraulic system. Lock-out / Tag-out the hydraulic
power source.
3.
The hydraulic test ports are located on the incoming hydraulic port blocks on each side of the attachment head.
4. Remove the plug from the test port and connect a gauge.
