At 500 hours, take oil samples from the engine, hydraulic tank, and axle systems to establish a baseline. Inspect the hydraulic return filter magnet for metallic debris before disposal. Monitor the coolant mixture ratio, ensuring 55% antifreeze for -36°C protection. Check the fuel water separator daily to prevent injector damage. Use JCB 15W/40 Multigrade oil for normal operation and JCB 10W/30 for temperatures below -10°C. Replace the air filter when the restriction indicator signals.

Address hydraulic leaks at the boom wear pad runways and extension ram pivots promptly. Inspect the swing ring bolts on tracked variants for torque loss. Check the turbocharger charge cooler boots for cracks and shaft play. Replace worn boom wear pads to prevent structural damage. Inspect the drive belts for tension and glazing. Verify the operation of the forward/reverse shuttle switch and indicator lights. Replace hydraulic hoses showing chafing or pinhole seepage.

At 2000 hours, inspect the boom, arm, and chassis structure for unauthorized welding or cracks. Measure swing ring play using dial indicators on tracked models. Check brake disc wear and immersed brake condition. Inspect injector spray patterns and replace as required. Service the cab HVAC system, checking evaporator condition and A/C pressure. Replace the cabin filter. Inspect the transmission torque converter for slippage or overheating signs.

In cold weather, use JCB 10W/30 oil and ensure the coolant mixture provides adequate freeze protection. In hot conditions, monitor the engine oil temperature and clean the cooling fan airflow path to reduce dust build-up. Grease pivot pins more frequently in dusty environments. Check the battery electrolyte level on non-sealed units. Inspect the stabilizer pivots for wear. Ensure the ROPS/FOPS structure is intact. Verify the operation of the backup alarm and horn.
