Starting the Engine

This machine can be operated under normal conditions in temperatures of 0°F to
104°F (-20°C to 40°C). Consult JLG for operation outside this range or under
abnormal conditions.

1. Make sure all controls are in “Neutral” and all electrical components (lights,

heater, defroster, etc.) are turned off. Apply parking brake.

2. If equipped with engine air-intake heater and temperature is below 40° F (4° C),

turn the ignition switch to “RUN” position and wait for engine air-intake heater
indicator on instrument panel to turn off.

3. Turn ignition switch to “START” to engage starting motor. Release key

immediately when engine starts. If engine fails to start within 20 seconds,
release key and allow starting motor to cool for a few minutes before trying
again.

4. After engine starts, observe engine oil pressure gauge. If gauge remains on

zero for more than five seconds, stop engine and determine cause before
restarting engine.

5. Warm up engine at approximately 1/2 throttle.

Note: Engine will not start unless transmission control lever is in “Neutral” and park
brake switch is applied.

WARNING

UNEXPECTED MOVEMENT HAZARD. Always ensure that transmission control
lever is in neutral and the service brake is applied before releasing park brake.
Releasing park brake in either forward or reverse could cause the machine to
move abruptly, causing an accident.
