Chapters Covered

This DX300LC-7 Operation and Maintenance Manual is organised into six main chapters plus the standard front matter, each one packed with illustrated procedures, tables and safety information:

• Safety
• Operating Controls
• Operation
• Inspection, Maintenance and Adjustment
• Transportation
• Specification

Safety

The largest chapter opens with the full set of safety decals, each reproduced with its warning text and location diagram, followed by comprehensive general safety rules covering operation, maintenance, fire prevention, electrical hazards, ROPS protection, emergency exits and environmental handling. Before you turn the key on a DX300LC-7, this chapter establishes every precaution the manufacturer expects.

Operating Controls

From the seat to the dashboard, every control in the DX300LC-7 cabin is labelled, illustrated and explained. Component locations, the operator’s area layout, all switches and panels, the display monitor and user menus, AVM system, proximity alarms, heater and air-conditioner controls, seat adjustments and the safety lever are all covered in this section.

Operation

Starting from the initial 50-hour break-in procedure, this chapter walks through daily operational checks, engine start and stop sequences, safety lever use, travel and steering, digging and lifting techniques, parking, towing, attachment handling and the hydraulic breaker, shear and quick coupler options. It also covers the auto grease system and lifting with quick couplers.

Inspection, Maintenance and Adjustment

The service heart of the DX300LC-7 manual, this chapter covers the complete 10-hour through 12,000-hour maintenance schedule. Fluid capacities, recommended lubricants, coolant and DEF handling, engine cooling service, hydraulic system venting, track tension, accumulator handling, filter replacement, bucket service and air-conditioning maintenance are all documented with procedures and intervals.

Transportation

Loading, unloading, lifting the machine, removing and reinstalling the counterweight and securing the excavator to a trailer are covered, along with the tie-down points and lifting-angle requirements that keep the machine stable during transport.

Specification

The final chapter delivers the DX300LC-7’s technical data: engine model and output, hydraulic pump ratings, swing and travel speeds, overall dimensions for both one-piece and two-piece booms, digging forces, working ranges and full lift capacity tables. Approximate weights of common workload materials round out the reference material.

What You Get in the PDF

This is the full manual, not a condensed summary. Every page of the May 2023 edition published by HD Hyundai Infracore is here, including:

• Safety decals with their exact machine locations
• Illustrated component locations for every major assembly
• Complete display monitor and user menu walkthrough
• Detailed maintenance schedules from 10-hour checks to 12,000-hour services
• Full specification tables and lift capacity charts
• Transportation, lifting and tie-down procedures

Why the DX300LC-7 Operation and Maintenance Manual Matters

The DX300LC-7 is a 31.6-tonne excavator with a 202 kW DL08P engine and 370 kg/cm² hydraulic system. Operating it without the correct procedures risks more than downtime — incorrect track tension, missed filter intervals, ignored safety decals or wrong lifting capacities can lead to serious injury or catastrophic machine failure. Having the manufacturer’s own guidance on hand means every adjustment, service task and safety check is done the way HD Hyundai Infracore intended.
