are in place. These items are installed for your safety.
Be sure the safety covers (fan cover, recoil starter cover) are in place.
Know how to stop the engine and tines quickly in case of
emergency. Understand the use of all controls.
Keep a firm hold on the handlebars. They may tend to lift during
clutch engagement.
