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.
If equipped for cold weather, -20°F to 0°F (-30°C to -20°C), see page 4-2 for hydraulic
warm-up procedure.
1. Make sure all controls are in "Neutral" and all electrical components (lights, heater,
defroster, etc.) are turned off. Apply park brake.
2. Turn the ignition switch to position 1 and wait until engine pre-heat indicator goes
out.
3. Turn ignition switch to position 2 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 two minutes before trying again.
4. After engine starts, observe indicators. If indicators remain on 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 is
applied.
ENGINE EXPLOSION. Do not spray ether into air intake for cold weather starting.
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.
