Use only the recommended lubricants and fluids to prevent chemical compatibility issues that could degrade seals or hydraulic performance. The manual lists precise fluid refill capacities for the engine oil, transmission, hydraulic circuits, coolant, and fuel systems, along with service intervals and recommended replacement intervals. When performing fluid service, ensure the system is at the proper operating temperature and follow the specified procedures for draining, filtering, and replenishing to avoid air entrainment or contamination. Proper labeling and storage of fluids, along with using clean containers and dispensing equipment, help maintain system cleanliness and extend component life. Always verify hydraulic fluid cleanliness and refrigerant or coolant specifications where applicable to maintain performance and reduce wear on pumps, valves, and heat exchangers.
The warranty and service policy section outlines coverage terms, limitations, and the proper process for submitting claims. It details the period of coverage, what components are covered, and the conditions under which warranties are voided, such as improper maintenance or unauthorized modifications. The manual emphasizes the importance of keeping accurate service records, including part numbers, serial numbers, and dates of service, to establish eligibility for warranty service. It also provides steps for initiating a warranty claim, whether through authorized service centers or the manufacturer's support network, and outlines required documentation like proof of purchase and defect descriptions. Understanding the warranty policy helps technicians manage customer expectations, plan repairs, and ensure compliance with manufacturer requirements during and after service work. This section reinforces the need for adherence to prescribed maintenance schedules to maximize warranty benefits and machine reliability.
