Proper lubrication not only reduces wear but also helps preserve fuel efficiency and reliability under varying operating conditions.

Warranty and service policy notes: Warranty terms and service policy notes outline coverage limits, excluded conditions, and required documentation for claims. Technicians should verify eligibility by inspecting the machine’s service history, confirming maintenance intervals, and ensuring all modifications or non-OEM parts are disclosed to the warranty administrator. This section also details customer responsibilities, such as providing proof of purchase, accurate reporting of faults, and timely submission of claims. Understanding these policies helps in delivering transparent customer service and supports efficient claim resolution while safeguarding both the customer and the dealership from ambiguities in coverage.
