JCB JS115–JS235 Series Common Problems This Manual Covers
JCB JS220 engine running during service prep, need to isolate systems before daily maintenance. p. 125
Stop the engine and remove the ignition key before starting maintenance. Release the hydraulic pressure and tank pressure as detailed on page 125. Isolate the battery to prevent accidental operation. Fill the DEF tank to its 54 L capacity before returning the excavator to service.
Manual Section: OperationWarning light flashing on dashboard display panel with active emissions system fault code. p. 363
Check the DECU display faults screen to read the specific error code. Press enter on the display panel to acknowledge all active faults. Inspect the Livelink 2 ECU ignition fuse on page 363 and replace it if blown with a new 5 A fuse.
Manual Section: Technical DataHydraulic oil return filter requires routine replacement during scheduled preventive maintenance interval. p. 192
Replace the hydraulic return filter at the 250h, 500h, 1000h, 2000h, or 4000h mark based on the schedule on page 192. Drain the old fluid and install the new filter element securely. Verify the hydraulic oil level is correct before operating the machine.
Manual Section: OperationEngine cranks slowly or fails to start during cold weather morning inspection. p. 363
Inspect the Engine ECM Supply 1 fuse location detailed on page 363. Replace the component with a 10 A fuse if the filament is broken. Drain water from the fuel separator and bleed the fuel system lines to remove trapped air before attempting another start.
Manual Section: Technical DataExcavator struggles to hoist heavy concrete barriers or large pipes during deep trenching operations. p. 246
Verify your load weight does not exceed the lifting hook capacity. Limit loads to 5 t for smaller models as listed on page 246, or 12.5 t for larger variants. Inspect the quickhitch mechanism for unsuccessful pin engagement before lifting any suspended loads.
Manual Section: MaintenanceFrequently Asked Questions
How do I reset the service light on a JCB JS115/JS130/JS145/JS160/JS180/JS190 excavator?
The service event symbol and fault indicator, which illuminate amber when a service is required, can only be cancelled by your JCB dealer. The operator cannot reset this light.
How do I reset fault codes on a JCB JS200/JS210/JS220/JS235 excavator?
To acknowledge active fault codes, press the control wheel on the active error log screen. For service events, the symbol and fault indicator can only be cancelled by your JCB dealer. For an engine oil change event, the operator can cancel the symbol and fault indicator by pressing the enter button, which will set the time for the next service event.
How do I clear hydraulic pressure or ECU codes after maintenance on a JCB JS excavator?
To release residual hydraulic pressure, turn the ignition key to the on position, lower the controls isolation lever, push the controls isolation switch, and then operate the hand controllers in all directions. Additionally, push the rubber boot on the hydraulic tank breather to release pressure from the tank. For ECU codes, the manual describes acknowledging active faults by pressing the enter button on the error log screen, but a general procedure for clearing all ECU codes after maintenance is not provided for the operator.
What are the torque specs for track roller bolts on JCB JS115 JS130 JS145 JS160 JS180 JS190?
For JCB JS115, JS130, JS145, JS160, JS180, and JS190 models, the lower (track) roller bolts (M16 diameter) require a tightening torque of 290 N.m, with a checking torque of 265 N.m. A 24 mm wrench is used for these bolts. It is recommended to use JCB Threadlocker and sealer (High Strength) and tighten to the listed torque.
What are the replacement specifications for hydraulic components?
The manual specifies replacement intervals for various hydraulic components. For example, the hydraulic return, suction, drain, and servo filters should be replaced at intervals ranging from 100 to 800 hours depending on use frequency. Hydraulic tank breathers should be replaced every 1000 hours. Hydraulic hoses, such as pump exit, boom ram line, dipper ram line, and bucket ram line hoses, should be replaced every 2 years or 4000 hours, whichever comes first. Replacement hoses must be of the same size and standard.
