This Doosan DX300LC-5 Operation and Maintenance Manual 2017 gives a technician the structure to work through the machine systematically. The early safety chapters establish the correct procedures for leaving the operator’s seat, locking out controls, and working around high-pressure hydraulic systems. The operating controls section explains the display monitor, user menu, heater and air conditioner panel, and the various switches and levers that control the DX300LC-5. The operation chapters cover travel, digging, lifting, attachment use, and abnormal conditions such as extreme cold, extreme heat, dusty areas, and working in water. The maintenance chapters are especially detailed, with daily, weekly, monthly, yearly, and biennial service tasks, fluid capacities, recommended lubricants, and component-specific inspection steps. The troubleshooting section helps diagnose electrical, engine, hydraulic, swing, travel, and cooling fan issues. The specification section provides dimensions, digging forces, working ranges, and rated lift capacity tables for the DX300LC-5.
Safety and Compliance Information
The manual includes extensive safety content, including signal words, safety decals, roll-over protective structure information, seat belt inspection, pressurized fluid warnings, fire and explosion prevention, battery hazards, and track tension adjustment precautions. It also covers federal and California emission control system requirements and owner warranty responsibilities. This is important reference material for anyone who needs to understand the required maintenance and safe operation of the DX300LC-5.
Maintenance and Troubleshooting Coverage
For the DX300LC-5, the maintenance section details grease points on the boom, arm, bucket, swing bearing, and front attachment pins. It explains how to check engine oil, hydraulic oil, coolant, fuel, DEF (AdBlue), swing reduction gear oil, travel reduction gear oil, and battery electrolyte. Service intervals are laid out from 10-hour daily checks through 50-hour weekly, 250-hour monthly, 500-hour quarterly, 1,000-hour six-month, 2,000-hour yearly, 4,000-hour biennial, 4,500-hour biennial DEF filter service, and 12,000-hour hose replacement guidance. Troubleshooting tables cover common problems such as a starter that does not operate, engine that cranks but does not start, low power, overheating, hydraulic controls that do not function, swing and travel issues, and cooling fan faults.
Specifications and Lift Capacity
The specification section gives the DX300LC-5 standard configuration data, including the DL08P engine, hydraulic pump details, digging capability, swing speed, travel speed, traction force, gradeability, ground pressure, track shoe width, and roller quantities. It also includes overall dimensions for one-piece and two-piece boom configurations, disassembled component weights, digging forces in SAE and ISO ratings, working range diagrams, and rated lift capacity tables. These tables are essential when the excavator is used for lifting objects, as they show how capacity changes with reach, boom length, arm length, counterweight, and track width.
