Disassembly for long-term storage should be performed only if required by manufacturer recommendations or if moisture, corrosion, or pest risk is suspected. Disconnect the battery and drain fluids according to local regulations before any disassembly. Store small fasteners and components in labeled bags or containers to prevent loss, and keep track of torque settings or wear indicators that may require inspection upon reassembly. When reassembling after storage, verify all seals, gaskets, and safety features are intact and replace any worn parts to ensure dependable starting and operation when the equipment is returned to service.

Disposal of fluids and components must comply with all applicable regulations for hazardous waste. Collect used oil, hydraulic fluids, and fuel in appropriate, labeled containers and transport them to an approved recycling or disposal facility. Filter and drain fluids in a manner that minimizes environmental impact, avoiding spills to soil or waterways. Remove and properly dispose of old batteries and any refrigerants, if present, at certified collection points. Recycle or repurpose metal components where feasible and follow local guidelines for recycling plastics and synthetic materials. Document disposal actions and retain receipts or proof of proper handling for accountability and compliance.

Maintenance of critical safety features during storage is essential to ensure safe operation when the unit returns to service. Inspect the blade or cutting deck for corrosion or dull edges if applicable, and protect it from moisture to prevent rust. Check the operator presence controls, safety switches, and the blade engagement mechanisms for proper function during the next startup, and perform any necessary bench tests if stored components were disturbed. Store fuel and lubricant containers in their original, sealed containers to prevent leaks and evaporation, and ensure caps are tight to minimize evaporation and contamination. Finally, perform a light lubrication of exposed moving parts where recommended by the manual to reduce corrosion and to keep the equipment ready for immediate deployment when conditions allow.
