This Komatsu PC300-8 PC350-8 Series manual is built around the machine’s actual working systems: the SAA6D114E-3 diesel engine, the hydraulic circuit and control valve arrangement, the monitoring system with its emergency, caution, and basic check monitors, and the undercarriage. Maintenance procedures are broken down by interval from every 50 hours through every 8000 hours, with separate procedures for the hydraulic breaker and attachment-ready configurations. Specifications cover operating weight, bucket capacity, engine output, travel and swing speeds, working ranges, and fluid capacities for the PC300-8, PC300LC-8, PC350-8, and PC350LC-8. Safety content includes the full safety label set, high-voltage cable clearances, high-pressure oil and fuel precautions, and ROPS/FOPS protective structure requirements.

What This Manual Enables You to Do

With this Operation and Maintenance Manual for the Komatsu PC300-8 and PC350-8 series, you can run daily walk-around checks, start and warm up the machine in cold conditions, operate the working modes correctly, carry out the full scheduled maintenance program, diagnose monitor warnings, replace filters and wear parts, adjust track tension, and service the air conditioner and hydraulic breaker circuit. Correct procedures and torque values matter on machines of this size. Using the wrong tightening torque, relief pressure, or fluid specification can damage the hydraulic system, shorten engine life, or create a safety hazard on site.
