1. Drain the fuel tank completely. Stored fuel containing ethanol or MTBE can start to go stale in 30 days.
Stale fuel has high gum content and can clog the carburetor and restrict fuel flow.
2. Start the engine and allow it to run until it stops. This ensures no fuel is left in the carburetor. Run the
engine until it stops. This helps prevent gum deposits from forming inside the carburetor and possible
engine damage.
3. While the engine is still warm, drain the oil from the engine. Refill with fresh oil of the grade
recommended in the Engine Manual.
4. Use clean cloths to clean off the outside of the machine and to keep the air vents free of obstructions.
Do not use strong detergents or petroleum based cleaners when cleaning plastic parts. Chemicals can
damage plastics.
5. Inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts
or bolts.
6. Store your unit on flat ground in a clean, dry building that has good ventilation.
Do not store the machine with fuel in a non-ventilated area where fuel fumes may reach flame,
sparks, pilot lights or any ignition sources.
