Upon arrival at the destination, perform a quick post-transport inspection to identify any new damage or leaks and restore all safety features before operating the unit again.

Disposal and recycling of components should follow local regulations and manufacturer guidelines to minimize environmental impact. Remove and dispose of fluids, such as engine oil, hydraulic fluid, and fuel, in accordance with hazardous waste handling procedures, using labeled containers and certified collection services. Recycle metal components, batteries, and electronic modules where accepted, and separate non-metallic materials for appropriate processing. When replacing parts, source OEM or recommended aftermarket components to maintain safety and performance standards, and document the disposal and recycling actions for maintenance records. Ensure that any pneumatically or hydraulically actuated systems are depressurized and isolated before removing components to prevent accidental releases. Finally, coordinate with local recycling centers or service depots to confirm accepted materials and any required documentation to comply with environmental regulations.
