If the engine has been running, allow itto cool forat least half
an hour before cleaning. Periodically remove dirt build-up from
the engine. Clean around the muffler. Clean with a brush or
compressed air.

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.

could cause a fire. Inspect and clean before every
use.
