What to do if my JLG Lifting Systems unit is off and the engine won't crank?
If the JLG Lifting Systems unit is off or disabled, and the engine won't crank, begin by checking the position of the selector switch and ensure the inhibit run is released. Inspect the warning LED and address any faults before restarting the RBS. Verify the start battery voltage, check the control fuse, and look for any loose wiring or connections.
Why is my JLG Lifting Systems engine temperature high?
If your JLG Lifting Systems engine temperature is high, check for any obstructions blocking the cooling airflow to the engine. Ensure the ambient temperature is within the engine's design limits. Also, verify the correct operation of the engine temperature sensor.
What to do if my JLG Lifting Systems engine is overcranking?
If the JLG Lifting Systems engine is experiencing an overcrank, first check the fuel level and connections. Then, verify the operation of the fuel solenoid and fuel pump. Check the start battery voltage. If the engine exhaust contains white smoke, it indicates fuel is entering the engine but the engine is not firing. If the ambient temperature is low, verify that the heater and/or glow plug are operating.
Why is my JLG Lifting Systems engine running with underspeed?
If the JLG Lifting Systems engine is running with underspeed, make sure there's enough fuel and combustion air going to the engine. Check the air cleaner. Also, check the governor lever setting and readjust it if needed.
What to do if my JLG Lifting Systems shows low oil pressure?
If the JLG Lifting Systems reports low oil pressure, check the oil level and the oil supply lines. Also, verify the correct operation of the oil pressure switch with a test gauge.
What causes overspeed in JLG Lifting Systems?
If the JLG Lifting Systems indicates an overspeed condition, verify the setting of the governor lever and readjust it if required.
What to do if my JLG Lifting Systems shows overvoltage?
If the JLG Lifting Systems shows an overvoltage, check the alternator output voltage.
What to do if my JLG Lifting Systems has no speed signal?
If the JLG Lifting Systems has no speed signal, check the wiring connections.
