Day 1 - Hand Over Theory Training
On the first day of the LiuGong Handover Theory Training, technicians from the Cebu Regional Office convened for a comprehensive session aimed at building a solid understanding of LiuGong heavy equipment. The training commenced with an introduction to LiuGong’s global history, highlighting its technological innovations and dedication to reliability, durability, and operator safety. Participants explored various machine categories, including excavators, wheel loaders, motor graders, and rollers, focusing on model codes, operating weights, and power train systems.
Discussions also covered engine configurations, particularly those from Cummins and LiuGong, along with insights into Tier 2 and Tier 3 emissions standards, fuel efficiency, and maintenance schedules. Engaging visual aids and interactive Q&A sessions facilitated a deeper understanding of hydraulic systems, cooling systems, and electrical components, with particular emphasis on interpreting machine specification sheets and adhering to safety protocols during handover inspections. This foundational training set the stage for practical applications in the following days, and the enthusiastic participation of the Cebu technicians underscored their commitment to delivering exceptional after-sales support, thereby enhancing LiuGong’s reputation in the Visayas region. The day concluded with a brief assessment to evaluate knowledge retention and identify areas for further development.
Day 2 - Machine Hand over actual training
On the second day of LiuGong's hand-over training, the emphasis shifted to practical machine operation and hands-on evaluations with technicians from the Cebu regional office. The day commenced with a concise review of safety protocols and machine controls, ensuring that all technicians were well-prepared before engaging with the equipment.
Under the leadership of Sir Jeovanni Aplaca, Service Country Manager/R&D Manager, along with the R&D support team, the training encompassed essential operational techniques, including proper startup, maneuvering, and safe shutdown procedures. Technicians had the chance to individually operate various machines, such as crawler excavators and wheel loaders, with guidance from R&D trainers.
Throughout the day, the R&D team highlighted the importance of preventive maintenance and demonstrated daily inspection processes. The Cebu team exhibited notable technical skill and enthusiasm, actively participating by asking relevant questions and sharing their experiences. By the conclusion of the training, all participants successfully completed the operational assessment, and the day wrapped up with a group discussion and feedback session, underscoring LiuGong’s dedication to technical excellence and robust regional support.
Day 3 - Liugong Electrical System training
On the third day of the LiuGong Electrical System training, technicians from the Cebu Regional Office engaged in a practical session aimed at diagnosing and testing essential electrical components and circuits within LiuGong equipment. The day commenced with a review of electrical theory, transitioning into hands-on demonstrations covering wiring diagrams, fuse boxes, relays, ECU connections, and battery systems.
Participants were organized into groups to conduct guided exercises using multi meters and diagnostic tools to detect circuit faults and voltage drops on actual machines. The training emphasized safe troubleshooting practices, the interpretation of error codes, and the application of genuine LiuGong diagnostic software. Simulated real-world scenarios allowed technicians to tackle common electrical issues, such as starting failures and sensor faults, thereby reinforcing their technical knowledge and problem-solving abilities.
The trainers also introduced updates on the latest LiuGong electrical technologies, including CAN bus systems and smart controls. The day wrapped up with a Q&A session and performance feedback, enabling participants to share insights and identify areas for improvement, ultimately enhancing their skills in maintaining and troubleshooting LiuGong's advanced electrical systems for better service quality and equipment uptime in the Visayas region.
Day 4: Cummins 6.7/7 Engine Theory Training
On the fourth day of the Cummins 6.7/7 Engine Theory Training, participants delved into the fundamental systems and operational principles of the 6.7L and 7L engine platforms. The session commenced with an in-depth exploration of the engine architecture, highlighting the inline-6 design, turbocharging mechanisms, and the high-pressure common rail fuel system. A significant focus was placed on the role of the Electronic Control Module (ECM) in regulating fuel injection timing, which enhances power output, fuel efficiency, and emissions management.
Participants analyzed the distinctions and commonalities between the 6.7
and 7-liter engines, particularly regarding performance metrics, torque
characteristics, and configurations tailored for specific applications.
The training also covered essential components such as the Variable
Geometry Turbocharger (VGT), EGR system, DPF, and SCR after treatment
systems, supported by real-world examples illustrating their
effectiveness in minimizing NOx and particulate emissions.
Additionally, diagnostic techniques utilizing Cummins in site software were introduced, offering valuable insights into fault codes, sensor data, and overall system health. The importance of preventive maintenance and accurate calibration was underscored to ensure the engines' long-term reliability. By the conclusion of the day, participants had developed a comprehensive understanding of the theoretical aspects of Cummins engines, equipping them for practical diagnostics and troubleshooting in future sessions, which is crucial for both field and workshop technicians.
Actual Dismantle of the engine
The hands-on training session focused on the disassembly of the Cummins 6.7/7 engine, offering participants valuable practical experience in engine tear down and component identification. The session commenced with a safety briefing, followed by a structured disassembly process led by a certified trainer. Participants systematically removed external components such as the turbocharger and EGR system, advancing to internal parts like the cylinder head and crankshaft. Each phase included thorough explanations of the components' functions, maintenance tips, and potential failure points, with a strong emphasis on proper tool usage and clean disassembly techniques to prevent damage.
Trainees deepened their understanding of the engine's architecture, including its emissions control and fuel injection systems, while referencing technical diagrams and manufacturer manuals to align with Cummins service standards. By the conclusion of the training, participants were equipped to confidently identify major components, recognize wear patterns, and accurately describe the disassembly sequence, significantly enhancing their troubleshooting and maintenance capabilities for Cummins mid-range engines in construction and heavy equipment contexts.
