1. Turn the machine off and observe the appropriate Lockout/Tagout procedures.
Severe injury can result if the machine is not properly locked out. Observe
electrical Lockout/Tagout procedures before performing maintenance.
Ensure all pressure is relieved or blocked from the hydraulic and high pressure
circuits before performing maintenance.
2. Drain the oil reservoir by connecting the inlet hose from an oil transfer pump to the drain
valve on the reservoir.
3. Open the shut off valve on the drain and pump the used oil out to a container.
NOTE
It is recommended that the empty reservoir be flushed with a few gallons of clean
oil to remove settled debris from the bottom.
4. Close the shut off valve and remove the inlet hose from the drain valve.
NOTE
Oil from a new drum does not meet the cleanliness requirements of the hydraulic
system. For this reason, it is important to use an oil transfer pump that will force
oil through the return filter into the reservoir.
