The engine is the most important part of the garden machinery. Persistent regular maintenance can prolong the service life of the engine and help machine users and managers save time and money. However, it is not easy to provide reasonable maintenance for the engine. The mechanics may wish to refer to the B&S engine winter maintenance plan.
With the advent of winter, the frequency of use of garden machinery such as lawn mowers and brush cutters has gradually decreased. When these machines are stored for a long time, they can try to fill the oil tank of the engine to prevent moisture from forming water in the tank. And prevent rust and dirt. When the fuel tank fills quickly, you can add the Briggs Gasoline stabilizer to the gasoline and allow the engine to run for a few minutes to allow the additive to circulate in the carburetor. Gasoline stabilizers prevent the condensation of key components of the gasoline intake system or carburetor.
Even if the engine is not running, there will be some evaporation of the fuel. Therefore, to remove the fuel tank cap of the engine, wrap it with aluminum paper and fix it with a rubber rope.
Take out the air filter, and spray the oil in the carburetor throat for about 5 seconds while running the engine. Then turn off the engine, remove the spark plug, and spray the oil into the cylinder 1 or 2 times (short injection). Before reinstalling the spark plug, turn the engine one or two turns to lubricate the piston, piston ring, and cylinder wall.
Thoroughly clean the engine before storing it for a long time. For lawn mowers, brush cutters, etc., remove grass clippings or other debris from the engine surface, disconnect the ignition line from the engine, and use a hose to flush away the remaining rags. Care should also be taken to use small sticks or other tools (not by hand or feet) to remove grass or debris that impede blade movement and clean it with water.
