Pre Start Inspection and Operation

5. As soon as the engine starts, release the starter key. The key will automatically
return to the RUN position (Item 3, Figure 3–11).
6. Leave the throttle setting at about the halfway position and allow the engine to
idle. This will begin warming the engine coolant and hydraulic oil.
7. In cold weather (32º F [0º C]) after about 5 minutes of engine idling, operate all
of the main hydraulic controls to cycle warmed hydraulic oil through the hydraulic
lines into the cylinders and hydraulic motors. Allow the engine to idle for another 5
minutes before beginning any machine operations.
When warming the hydraulic oil, the operator must cycle all functions every 5 minutes.
This will assist in warming the hydraulic oil in all systems evenly and more rapidly.
Failure to do this can cause the control systems to stick creating a run-away situation.
Machine Shut-down
To safely shut the machine down, the operator must:
1. Park the machine on a solid, level area.
2. Lower the loader arm and attachment to the ground.
3. Idle the engine for 5 - 10 minutes to allow the machine to cool down.
4. Shut off the engine.
5. Clean off any accumulated mud and/or dirt from the machines operating surfaces,
operator’s platform, both track assemblies, etc.
