JCB 8018 CTS Common Problems This Manual Covers
JCB 8018 CTS Mini Excavator hydraulics work briefly after lowering the safety lever then stop p. 66
Check the left hand console is fully lowered to the normal position to connect excavator controls as shown on page 66. Test if the accumulator maintains limited hydraulic pressure for emergency use on page 161. Verify the hydraulic tank is filled to the 25.4 Litres capacity.
Manual Section: OperationAll hydraulic controls suddenly become dead during use or fail to respond to joystick inputs p. 311
Inspect the excavator and track main relief pressure on page 311. Connect your gauge and verify the system reaches exactly 230 bar. If pressure drops, test the slew main relief pressure to ensure it maintains 160 bar before inspecting the safety interlock switch.
Manual Section: SpecificationsRubber tracks slipping or popping off the idler wheel during heavy turns on uneven ground p. 244
Measure the track sag at the center roller as instructed on page 244. Adjust the track tension to the manufacturer-specified value for rubber tracks. Clean the track gearbox and check the oil level if the machine tracks poorly in either direction.
Manual Section: Tracks and Running Gear MaintenanceEngine cranks normally but will not start after the glow plug heating cycle completes
Review the maintenance intervals for fuel filter replacement and inspect the sedimenter for water contamination. Check fuel delivery and verify the glow plug system is functioning correctly. Consult the Routine Maintenance section for the full pre-start inspection checklist.
Manual Section: Routine MaintenanceFrequently Asked Questions
How do I reset the safety lever/hydraulic lock on a JCB 8018 CTS?
The hydraulic controls are enabled by lowering the left hand console and handle A to the normal operating position. Raising the left armrest prevents the services from operating. To re-enable, ensure the armrest is replaced firmly to connect the excavator controls and allow normal operation of the levers.
How do I reset fault codes on a JCB 8018 CTS?
To reset fault indications on the JCB 8018 CTS, set the starter key to the OFF position. This action will reset all operations after a warning indicator has displayed a machine fault.
How do I reset the immobilizer or alarm on a JCB 8018 CTS?
To disarm the keypad immobiliser, insert the starter key and turn it to position I, then press the MD button, enter your four-digit PIN, and press the ENT button. For the unique key system, insert the starter key and start the engine normally — the immobiliser disarms automatically when the correct key is detected.
Why does the JCB 8018 CTS hydraulics stop after 1-2 seconds when the safety lever is down?
The manual states that when the left hand console and handle A (safety lever) are in the *raised* position, the excavator controls cannot be operated, thus disabling the hydraulics. If the hydraulics stop when the safety lever is *down*, it suggests the lever might not be fully engaged in the normal operating position, or there could be a malfunction in the safety interlock system.
