Take oil samples from the engine, hydraulic, axle, and final drive systems at the 500-hour interval to create a baseline for future comparison. Inspect the hydraulic return filter magnet for metallic debris. Interpret hydraulic oil samples against the 500-hour baseline at the 1000-hour service. Use JCB Engine Oil Special or equivalent 15W-40 diesel oil. Check the turbocharger shaft play and wastegate function. Monitor the ECM for developing faults via the ServiceMaster tool.

Replace the primary and secondary fuel filters to protect common-rail injectors. Inspect the alternator and starter load to catch dying electrical components. Check the turbocharger boot condition and shaft play. Service the brakes including disc wear and immersed brake condition. Inspect hoses and cylinders for chafing and pinhole seepage. Check the belt tension for the alternator, A/C, and fan. Grease all pin points including the boom, arm, bucket, and kingpost pivots.

Drain the hydraulic tank and clean it at the 2000-hour interval, then refill with JCB-spec hydraulic oil. Inspect structural components for cracking including the boom, arm, loader arm, and chassis. Measure swing ring play using a dial indicator. Check the injector spray pattern via the diagnostic tool. Inspect the slew ring bolts and torque them to spec. Measure the undercarriage against JCB wear limits. Replace the transmission oil and filter.

Check the coolant level in the expansion tank. Drain, flush, and refill with JCB-spec long-life coolant at the 1000-hour interval. Inspect the cab HVAC including A/C pressure and cabin filter. Check the battery electrolyte on non-sealed units. Inspect the track tension on JS excavators. Verify the tire pressure and cut damage on wheeled machines. Check the seat belt, mirrors, horn, and backup alarm. Ensure the ROPS/FOPS is intact.
