1 d. Retract all cylinders (packer, crusher panel, tailgate, etc.)
1 e. Disengage the hydraulic pump
1 f. Stop the engine
2. Lock out and tag out the vehicle (see Locking Out and Tagging Out the Vehicle on page 20).
3. Close the shut-off valve on the suction line (see Figure 2-13).
4. Disconnect the suction line from the pump.
5. Place a clean container (minimum capacity: 60 gallons) under the disconnected end of the
suction line to empty the hydraulic tank.
6. Open the shut-off valve to let the oil flow into the container.
7. When the bulk of the oil has been emptied from the tank, remove the drain plug (see Figure

Place a small container under the plug.
8. Once the tank has been completely emptied, replace the drain plug and reconnect the suction
line to the pump.
