Monitor LPG system integrity regularly. Check the vaporiser and carburettor for leaks at every 500-hour interval. Inspect the LPG tank pressure relief valve annually. Use JCB-spec long-life coolant and replace it at 1000 hours. Sample hydraulic oil at 500 hours to detect wear metals in the enclosed hydrostatic drive system. Check engine oil quality at each 250-hour change; JCB engines tolerate 500-hour intervals but severe duty may require earlier changes. Inspect the air filter restriction indicator frequently.

Common LPG system issues include faulty vaporisers and carburettor jets. Replace spark plugs if fouling occurs. Inspect the drive belt tension at 500 hours; a loose belt causes alternator failure. Check the steering unit valve for internal leaks if steering feels sluggish. Inspect the hydraulic return filter magnet for metallic debris. Replace the hydraulic tank breather at 1000 hours to prevent tank vacuum collapse. Check the LPG pre-filter element for blockage if power drops.

Major overhaul points include the hydraulic variable displacement pump and wheel drive motors. Inspect piston cover seals and charge pressure relief valves at 2000 hours. Check the turbocharger shaft play and wastegate function at 1000 hours. Inspect the engine crankshaft main bearings and camshaft wear during major engine service. Check the drive axle hub seals and shim wear. Inspect the lift arm pivot pins and wear pads for excessive clearance.

In cold weather, check the LPG tank heater operation and ensure the vaporiser functions correctly. Inspect coolant concentration for freeze protection. In dusty environments, clean the air filter more frequently and check the engine crankcase breather. Inspect hydraulic hoses for chafing, especially near the telescopic boom. Check cab HVAC system for proper operation. Inspect the LPG tank for corrosion, particularly in coastal areas. Ensure fire extinguisher is charged and accessible.
