The core principles for preparing a remote-controlled lawn mower for long-term storage (generally referring to idle time exceeding 1 month) are cleaning and drying, power-off protection, and component maintenance. These steps prevent body rust, battery damage, and mechanical jamming. The specific procedures are as follows:
After powering off, remove the blades. Use a brush or a high-pressure water gun (low-pressure mode) to clear grass clippings, soil, and sap residues from the cutter head and blades, avoiding corrosion of metal parts caused by dried-on debris.
Check the blade condition: For mild rust, polish with sandpaper to remove rust; if the wear is severe, replace the blades directly to prevent rust spread.
Wipe dust and oil stains off the body surface with a damp cloth. Focus on cleaning heat dissipation holes and sensor lenses (such as obstacle avoidance cameras and LiDAR) to prevent clogging or reduced sensitivity.
Clear soil and gravel from the gaps of chassis rollers and tracks to avoid component deformation or rotation jamming due to long-term accumulation.
After cleaning, place the lawn mower in a well-ventilated, cool area to air-dry naturally. Do not expose it to direct sunlight. Ensure no residual moisture remains inside the body and battery compartment to prevent damp-induced short circuits.
Lithium batteries: Charge the battery to 50%–60% and then disconnect the power supply. This is the safe storage level for lithium batteries, which prevents cell failure caused by over-discharge and aging acceleration caused by full-charge storage.
If the battery is detachable, it is recommended to remove it for separate storage; for non-detachable models, turn off the main power switch.
Store the battery in a dry, cool, room-temperature (10℃–25℃) environment, away from heat sources (heaters, stoves), flammable and explosive materials, and metal conductors to avoid short circuits.
For long-term storage (more than 3 months), recharge the battery every 1–2 months to maintain the power level at around 50%.

Apply a small amount of special lubricating oil or grease to drive wheel bearings, track pins, cutter head rotating shafts, and other parts to prevent rust and jamming during long-term idleness.
Note: Do not use excessive lubricant to avoid dust adsorption and secondary wear.
Apply a thin layer of anti-rust oil to metal parts such as blades and bolts; if anti-rust oil is unavailable, a small amount of engine oil can be used as a substitute.
Repair paint scratches on the metal body shell with a touch-up pen to prevent rust expansion.
Priority should be given to indoor dry and ventilated areas, such as garages and storage rooms. If outdoor storage is unavoidable, cover the mower with a dedicated waterproof and dustproof protective cover to avoid rain, direct sunlight, and dust accumulation.
Place the lawn mower horizontally to prevent lubricant accumulation or component deformation due to pressure from tilting. If the height adjustment function is available, keep the cutter head in a raised position to avoid blade contact with the ground and moisture absorption.
Remove the battery from the remote control to prevent circuit board corrosion caused by battery leakage. Clean the remote control buttons and antenna, and store them in a dry packaging box.
Store accessories such as chargers, spare blades, and wrenches separately from the lawn mower to avoid component extrusion or body scratches. Place the charger in a moisture-proof bag to prevent interface dampness.
