Featuring a modular arrangement of comprehensive operation and maintenance guidance, this document encompasses safety protocols, system fundamentals, service routines, and engineering particulars for the Komatsu compact excavator lineup. The manual provides control systems documentation, encompasses hydraulic circuit guidance, integrates specification tables, and systematically addresses maintenance schedules covering 100-hour through 2000-hour service intervals.
Factory procedures are documented for attachment operations including hydraulic breaker configuration, bucket replacement sequences, and control pattern selection between ISO and J/D patterns. Suspension service documentation covers undercarriage maintenance including track tension adjustment, rubber shoe replacement procedures, and track shoe bolt tightening torque specifications. Disassembly instructions are documented for fuel system service, hydraulic fluid management, and cooling system flushing protocols. Wear limits are specified for engine components, hydraulic seals, and safety-critical hoses requiring periodic replacement. System operation descriptions cover steering mechanisms, swing control coordination, and work equipment hydraulic valve sequencing. The document's strategic organization presents cold weather operation guidance, long-term storage protocols, and emergency troubleshooting procedures addressing electrical system failures, hydraulic circuit problems, and engine performance anomalies.
Technical data encompasses working ranges (maximum digging reach of 4,600-5,320 mm, maximum digging depth of 2,650-3,150 mm), operating weight specifications (3,005-3,880 kg depending on configuration), and travel speed parameters. Lubricant specifications identify SAE grade requirements (10W, 30, 40, 10W30, 15W40 engine oils; SAE80/90/140 gear oils; ethylene glycol antifreeze formulations) with supplier compatibility tables listing approved products from KOMATSU, AGIP, AMOCO, ARCO, BP, CALTEX, CASTROL, CHEVRON, and other international suppliers. The manual documents torque specifications for metric fasteners ranging from M6 through M39, establishing target values and permissible ranges for hydraulic hose connection points.
Safety critical parts requiring periodic replacement are identified with 2-year or 4000-hour intervals for fuel and hydraulic hoses, and 3-year replacement cycles for seat belts. Wiring diagrams, hydraulic circuit schematics, and control panel layouts facilitate system understanding. Optional equipment guidance covers air conditioner operation, radio receiver controls, and windshield washer fluid maintenance. The manual documents torque specifications for the [component] to ensure proper clamp load consistency.
