During transport the blade should be fitted with a blade cover or be removed. Top blade speed is not always necessary but low speeds lead to trouble. Avoid cutting small stems at the eight o`clock at low speeds. Twigs and stems get caught in the blade/blade guard assembly. When debris gets caught in the blade, try rotating the blade backwards against a cut stump or tree. Remove the saw from the fueling area before starting. Ensure that the saw blade is free to turn before attempting to start the engine. Take care not to plug the muffler with mud when filing or doing repairs. The saw will not start with mud in the muffler.
