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. Set parking brake.
2. Turn ignition switch to position 1. If temperature is below 32°F (0°C), wait for
preheat light to go out.
3. Turn ignition switch to position III 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, if oil pressure does not rise for more than ten seconds, the
engine oil pressure indicator will illuminate on instrument panel and buzzer will
sound. Stop engine and determine cause before restarting engine. Reference
engine manual for minimum pressure at operating temperature.
5. Warm up engine at approximately 1/2 throttle.
Note: Engine will not start unless transmission control lever is in “Neutral” and park
brake is applied.
WARNING
ENGINE EXPLOSION. Do not spray ether into air intake for cold weather
starting. Failure to comply could result in death or serious injury.
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 resulting in death or serious injury.
