    4. All repairs will be done in accordance with the original equipment manufacturer's specifications, recommendations, and procedures.

    5. Test sub-assemblies and complete assembly with the prescribed test equipment in accordance with the original manufacturer's test recommendations.

    6. This classification of repair carries the repair station's standard warranty.

  • CLASSIFICATION II

    Necessary Minor Repairs

    1. Repairs of defects to a sub-assembly and/or complete assembly, as designated by the customer or noted by the service shop after a visual inspection.

    2. Test unit and sub-assembly according to manufacturer's recommendations and report findings to the customer.

    3. Under the warranty period, the repair station alone is responsible for that portion of repair work it was instructed to perform.

  • CLASSIFICATION III

    Necessary Minor Repairs

    1. External cleaning of complete assembly and testing of assembly according to manufacturer's recommendations.

    2. If the test does not meet the requirements, the customer will be advised, and permission will be requested to make further repairs under either classification I or II.

    If the test meets the requirements, the unit will be returned to the customer for service. Still, the repair station WILL NOT be held responsible for the unit's longevity since the internal mechanical parts were not visually inspected and the unit was not overhauled.
