[. . . ] Disconnect the spark plug wire and keep it away from the spark plug. Do not tamper with governor spring, links or other parts to increase engine speed. Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation. Engine parts, especially muffler, become extremely hot. Allow muffler, engine cylinder and fins to cool before touching. Remove accumulated debris from muffler area and cylinder area. It is a violation of California Public Resource Code, Section 4442, to use or operate the engine on any forest-covered, brush-covered, or grass-covered land unless the exhaust system is equipped with a spark arrester, as defined in Section 4442, maintained in effective working order.

On models equipped with air filter shown in Figure 13, install the cover tabs (E) into the slots (F). Install cover and secure with the fasteners. If replacement parts are required, make sure to use only original equipment replacement parts. Replacement parts must be the same and installed in the same position as the original parts or fire could result. After the oil has drained, install and tighten the oil drain plug. Fuel System Fuel can become stale when stored over 30 days. stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs & Stratton FRESH START® fuel stabilizer, available as a liquid additive or a drip concentrate cartridge. There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system. The engine and fuel can then be stored up to 24 months. If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel.
