Storage instructions

Engines stored over 30 days need to be protected or drained

of fuel to prevent gum from forming in fuel system or on

essential carburetor parts.

1. For engine protection, we recommend use of

Briggs & Stratton Gasoline Additive, Part No.

5041, available from an Authorized Briggs &

Stratton Service Dealer. Mix Additive with

fuel in fuel tank or storage container. Run

engine for a short time to circulate Additive

through carburetor. Engine and fuel can be

stored up to 24 months.

P/N 5041

Your Service Dealer has single-use

pouches of Gasoline Additive available.

Note: If engine is operating on oxygenated or reformulated

gasoline (gasoline blended with an alcohol or an ether),

remove all fuel from tank and run engine until it stops from

lack of fuel. If engine is stored with gasoline in fuel tank, we

recommend the use of Gasoline additive, Part No. 5041.

2. While engine is still warm, drain oil from crankcase

(see page 6). Refill with fresh oil of recommended grade

(see chart page 3).

3. Remove spark plugs and pour about 1 oz (30 ml) of

engine oil into cylinders. Replace spark plugs and crank

slowly to distribute oil.

4. Clean dirt and chaff from cylinders, cylinder head fins, blower

housing, rotating screen and muffler area (see page 7).

5. Store in a clean and dry area, but NOT near a stove,

furnace or water heater which uses a pilot light or any

device that can create a spark.
