4. Rotate and hold the start switch (Item 1, Figure 3–9) in the START position until the engine 

starts.

The low engine oil pressure warning horn will sound when the ignition key is turned 

to the “ON” position. When the engine starts and oil pressure reaches normal, the horn will 
shut off.

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.

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.

If the engine oil drops below the engine manufacturers required levels, a warning horn 

will sound. Immediately shut down the engine to prevent severe damage. 

DO NOT use the machine until repairs have been made.
