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.

Engines stored between 30 and 90 days need to be treated with

a gasoline stabilizer such as STA-BIL® and engines stored over 90

days need to be drained of fuel to prevent deterioration and gum

from forming in fuel system or on essential carburetor parts. If

the gasoline 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 tank by running engine until it stops

from lack of fuel.

WARNING: Never leave engine unattended while

running.

2. Change oil. See Oil Change section.

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 the Pre-Operation Check

section of this manual.

2. If the fuel was drained during storage preparation, fill the

tank with fresh gasoline. 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.
