With a bare rental, the question often comes up as to who is responsible for what. First and foremost, the Lessor (owner of the equipment) is responsible for the overall service lifespan of the equipment. That means that the components that make up the machine assembly all have a lifespan that the Lessee isn’t responsible for during the lease period. Such examples are the Motor. A well-maintained diesel motor should have a lifespan of 15,000 hours or more, but at times, properly maintained equipment does fail earlier than its expected service life, and that is not the burden of the Lessee. The Lessor is responsible for the machine and its components for the maintained and expected life span of those components, including labor and parts to repair and replace them at the end of their undamaged life span. The Lessor, however, has no control over the Lessee location and conditions of use and when the machine is used; therefore, the Lessee is responsible for the costs of travel, lodging, and support equipment to service the machine at the Lessee’s location or transport to an approved service center. If a machine requires service, it is best for the machine to be brought to an approved shop for the service.
