The schedule itself is laid out as Initial 1000 hours, When required, Checks before starting, Every 50, 250, 500, 1000, 2000, 4000, 5000 and 8000 hours. Maintenance procedures include air cleaner element service, cooling-system cleaning, track shoe bolt tightening and track tension adjustment, bucket tooth, side cutter and shroud replacement, bucket clearance adjustment, washer fluid top-up, air conditioner service, washable floor cleaning, hydraulic system air bleeding, greasing, swing circle and swing pinion lubrication, battery electrolyte checks, air conditioner compressor belt tension, swing machinery and final drive oil checks, fuel pre-filter and main filter cartridge replacement, engine oil and filter change, radiator, oil cooler, aftercooler and condenser fin cleaning, fresh/recirc air filter cleaning, hydraulic tank breather and additional breather element replacement, hydraulic oil filter element replacement, swing machinery oil change, damper case oil level, exhaust clamp checks, fan and alternator belt checks, breaker accumulator nitrogen pressure checks, corrosion resistor cartridge replacement, final drive oil change, hydraulic tank strainer cleaning, control-circuit accumulator function check, and a dedicated hydraulic-breaker maintenance interval schedule.

Installation and removal of the demolition digging boom is described step by step, including removal of high reach work equipment, fitting demolition digging equipment, work equipment flow valve settings for high reach and dig boom, removal of demolition digging equipment, connecting the digging arm to the demolition digging boom, and full purging of air from hydraulic cylinder lines, boom lock valve PPC circuit and drift-preventative valve PPC circuits. Transport procedures for high reach and demolition digging configurations, plus specifications for high reach (max working height 23,060 mm, max forward reach 12,000 mm, operating weight 48,570 kg with 700 mm shoes and 2,500 kg demolition attachment), medium reach, low reach and digging configurations are also included, along with lifting capacity charts for the straight and bent digging boom positions.

Why This Komatsu PC350LC-8 Operation and Maintenance Manual Belongs in the Cab

This is the manual that covers the working life of the PC350LC-8 and PC350NLC-8 excavators from first start-up to major service. It is the same form-numbered document issued under UEAM007002, and it holds the exact procedures and values Komatsu specifies for these machines: warm-up times by ambient temperature, preheat duration at -10 C, -20 C and -25 C, turbo-protect behaviour, working mode selection logic, safety valve set pressures, accumulator charge checks, track tension deflection of 10-30 mm, track shoe bolt torque of 393 +/- 39 Nm plus 120 +/- 10 degrees, final drive plug torque of 68.6 +/- 9.8 Nm, hose end torque tables, engine and hydraulic oil refill capacities and every greasing interval from every 50 hours through to every 8,000 hours. For an owner running a K50001-and-up machine, this manual is what keeps a repair a repair rather than a guess.

For the independent workshop, the same content supports fault diagnosis as well as routine service: the electronic control system error code chart (E02 pump control, E03 swing brake, E10/E11 engine controller, E14 throttle, E15 engine sensors, E0E network), the electrical-system troubleshooting table for lamp, alternator, starting motor, preheat and oil-pressure monitor faults, the chassis troubleshooting table for slow travel, air-sucking pump noise, overheating, track derailment and no-swing conditions, and the engine troubleshooting table for oil pressure, coolant, starting, exhaust colour and combustion noise. Every one of these is written against the machine it belongs to, not a generic diesel engine.

The demolition supplement gives the same depth for the PC350LCD-8 and PC350NLCD-8, where a mistake is expensive: intermediate link operation, crusher open/close, attachment rotation, tilting cab controls, boom angle warning sensor adjustment, the exact hydraulic flow valve dimensions (6 mm, 5.5 mm, 9 mm, 11 mm, 14.5 mm, 15.5 mm) for high reach and dig boom configurations, the boom lock valve PPC air purge procedure and the pin retract circuit valve settings. Nothing on this side of the machine is left to intuition.
