To prepare the lawn mower for off-season or long-term storage, perform those items outlined in the maintenance section of your mower’s Owner's Manual. See your mower’s operator’s manual for specific details.
1. Fuel System Preparation: The most important part of off-season or long-term storage is proper preparation of the fuel system. The last fuel fill should be treated with a fuel conditioner (a separate fuel conditioner is not necessary when using Lawn-Boy Generation II 2-Cycle Ashless Oil with added fuel stabilizer in Lawn-Boy 2-cycle engines). The mower’s fuel tank should be drained using a hand pump, available through most hardware or home center retailers, or run dry. Then, repeatedly choke (if applicable), prime and start the engine until it absolutely will not start. This will ensure the fuel system is properly prepared and lessens the potential for varnish and gum deposits forming in the fuel system resulting in starting difficulties later on.
2. Cylinder/Piston Care:
- Remove spark plug and add about one tablespoon of oil through spark plug hole.
- Slowly pull the starter rope several times to distribute the oil.
- Reinstall spark plug, but do not connect spark plug wire.
- Slowly pull recoil starter until resistance is felt due to compression pressure, then stop.
- Release starter tension slowly to prevent engine from reversing due to compression pressure.
- This position closes both the intake and exhaust ports which prevents corrosion of the cylinder bore.
3. Tighten Fasteners and Clean
- Tighten screws, bolts and nuts as needed.
- Repair or replace damaged parts.
- Clean unit thoroughly.
4. Battery (if applicable)
- Fully charge battery prior to storage.
- Store mower in a cool, dry place.
5. Lubricate unit per the Owner's Manual.
6. Touch up all rusted or chipped paint surfaces.
- Ensure engine has properly cooled.
- Cover unit and store in a clean, dry location out of the reach of children.
Note: Never store unit in house (living area) or basement where ignition sources may be present such as hot water and space heaters, clothes dryers and the like. Gasoline and fumes are highly flammable and explosive. Fumes can also be dangerous if inhaled.
