Collect used fluids in approved containers and label them clearly for recycling or proper disposal at an authorized facility. Metal components such as cutting decks, frames, and fasteners are typically recyclable, but exposure to oil and coolant requires cleaning before recycling. Plastics and composite materials should be sorted according to local recycling programs, with contaminated parts treated as waste if recycling streams cannot accommodate them. When replacing worn or damaged parts, consider sustainable options and follow proper decontamination procedures to minimize environmental impact during deconstruction and disposal.

During long-term storage, perform a periodic inspection schedule to confirm that seals remain intact, lubricants do not degrade, and corrosion does not develop on exposed surfaces. Maintain a record of storage dates, fluid levels, and any signs of deterioration so future technicians can understand prior storage conditions. Ensure that ventilation is not obstructed around the stored equipment to prevent humidity buildup, which can accelerate rust or mold growth on internal components. If the unit is stored outdoors, use a breathable, weather-resistant cover and elevate it slightly off the ground to avoid ground moisture contact. Adhering to these storage, transport, and disposal practices helps preserve the functionality, safety, and environmental compliance of the BIGDOG DIABLO 60 over its service life.
