3. Pull the chock knob (Item 3,

5. As soon as the engine starts, release the starter key. The key will automatically return to
the RUN position.
6. Slowly push the choke knob inwards. If the engine begins to sputter, pull the choke knob
outwards slightly until the engine smoothes out. As soon as the engine warms up and
begins to run rough, push the choke knob inwards to the normal operating position.
7. Leave the throttle setting at about the halfway position and allow the engine to idle. This
will begin warming the hydraulic oil.
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.
8. 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.
