Starting the Engine
This machine can be operated under normal conditions in temperatures of -20°C to
40°C (0°F to 104°F). 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 park brake.
2. Turn ignition switch to position I. If active, enter anti theft code.
3. If temperature is below 32° C (90° F), turn ignition to position II for engine
preheat and hold up to twelve seconds.
4. 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.
5. After engine starts, observe engine oil pressure indicator. If indicator remains
on for more than five seconds, stop engine and determine cause before
restarting engine.
6. 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
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.
WARNING
ENGINE EXPLOSION. Do not spray ether into air intake for cold weather
