At the 500-hour interval, take baseline oil samples from the engine, hydraulic tank, and axle housings. Compare future samples against this baseline to detect bearing wear or contamination early. Monitor the hydraulic return filter magnet for metallic debris. Use JCB Engine Oil Special or equivalent 15W-40 diesel oil meeting API specifications. Check coolant concentration and condition at the 1,000-hour service to prevent corrosion in the EcoMAX engine cooling system.

Inspect hydraulic hoses daily for chafing and pinhole seepage, particularly on the boom and stick cylinders. Replace ground-engaging teeth and cutting edges every 800–2,000 hours depending on material abrasiveness. Check track tension and roller condition to prevent premature undercarriage wear. Address minor leaks at the kingpost and boom pivot points immediately to maintain hydraulic system efficiency and prevent component damage.

The 2,000-hour service requires a full hydraulic oil change and tank cleaning. Inspect the swing ring for radial and axial play using a dial indicator on JS-series excavators. Check turbocharger shaft play and charge cooler boot integrity on Dieselmax engines. Torque slew ring bolts on tracked models. Inspect brake discs and immersed brake packs for wear. Replace injector spray patterns as required by diagnostic tool readings.

In cold climates, use JCB Super Universal Agricultural oil rated for -15°C to 30°C. Ensure the cooling system is flushed and refilled with JCB OAT coolant to prevent freezing and overheating. Store the machine under cover to reduce corrosion on the undercarriage and hydraulic cylinders. Check battery electrolyte levels in non-sealed units. Inspect cab HVAC filters and evaporator condition to maintain operator comfort in extreme temperatures.
