IMPORTANT: Do not spray engine with water to clean because water could contaminate fuel. Using a garden hose or pressure washing equipment can also force water into the air cleaner or muffler opening. Water in the air cleaner will soak the paper element, and water that passes through the element or muffler can enter the cylinder, causing damage

WARNING

Accumulation of debris around muffler could cause a fire. Inspect and clean before every use.

Storage

CAUTION

Failure to use a fuel stabilizing additive or completely run the engine until it’s out of fuel before off-season storage may result in damage to your engine’s carburetor. Subsequent damage would not be covered under the manufacturer’s warranty. Fuel that will be stored longer than 30 days needs to be pre-treated upon purchase with fuel stabilizer to prevent gum and varnish from forming in the engines fuel and intake system. Improper fuel storage can result in hard starting, no starting, stalling and poor performance. If the fuel in your engine deteriorates during storage, you may need to have the carburetor, and other fuel system components, serviced or replaced.

  1. Remove all fuel from fuel tank by running engine until it stops from lack of fuel.
    WARNING
    Never leave engine unattended while running

  2. Change oil. See Oil Change

  3. Remove spark plug and pour about 1/2 an ounce of engine oil into cylinder. Replace spark plug and crank slowly to distribute oil.

  4. Clean debris from around engine, under finger guard, and under, around and behind muffler. Touch up any damaged paint, and coat other areas that may rust with a light film of oil.

  5. Store in a clean, dry and well-ventilated area away from any \appliance that operates with a flame or pilot light, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark producing electric motor, or where power tools are operated.

  6. If possible, also avoid storage areas with high humidity, because that promotes rust and corrosion.

  7. Keep the engine level in storage. Tilting can cause fuel or oil leakage.

Removing From Storage

  1. Check your engine as described in Pre-Operation Check on
  2. If the fuel was drained during storage preparation, fill the fuel tank with fresh fuel. If you keep a container of gasoline for refueling, make certain it contains only fresh fuel. Gasoline oxidizes and deteriorates over time, causing hard starting.
  3. If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This is normal.
