Manual Section: OperationFrequently Asked Questions
How do I reset the JCB 16C-1/18Z-1 immobilizer or 2GO system?
The manual does not describe a general 'reset' procedure for the immobilizer system or a '2GO system'. However, it provides instructions for disarming the immobilizer by entering a four-digit PIN code (for keypad systems) or by using an ignition key (for unique key systems). To disarm the immobilizer with a keypad, turn the ignition key to position 1, enter your four-digit PIN code, and push the 'ENT' button. For unique key systems, simply put the ignition key in the ignition switch and start the engine. The immobilizer arms automatically after two minutes when the engine is stopped and the ignition key is removed.
What do the warning lights or fault codes mean on a JCB 1-2 tonne mini excavator?
The manual provides a table explaining the meaning of various warning and indicator lamps. For example, an illuminated red light for 'Engine oil pressure' indicates that oil pressure is too low, and if it remains on after starting, the engine should be stopped immediately. A red light for 'Battery charging condition' with a buzzer indicates the battery is not charging. An amber light for 'Master warning' suggests contacting the JCB dealer, while a red light means stopping the machine immediately.
What are the replacement specifications for Hydraulic hoses / pipework?
When replacing hydraulic hoses, it is crucial that the replacement hoses are of the same size and standard as the original ones. If you require more information or are unsure about the correct specifications, you should contact your JCB dealer for assistance. Damaged hoses can lead to fatal accidents, so regular examination of hoses and their fixtures is essential.
What are the replacement specifications for Rams / cylinders?
The manual does not provide specific replacement specifications for rams or cylinders. Instead, it advises to extend each ram fully, one at a time, and visually examine them for score marks, dents, leaks, or similar defects. If a ram piston appears defective, you should contact your service engineer or JCB dealer for further action.
