(2) Do not alter or remove any part of machine safety system. (3) Before starting the engine, make sure that all shift levers are in neutral positions or in disengaged positions. (4) Never start the engine while standing on ground. Start the engine only from operator's seat. OOOOOZ00030 SAFETY WORKING (1) Do not work on the machine while under the influence of alcohol, medication, or other substances or while fatigued. (2) Wear close fitting clothing and safety equipment appropriate to the job. (3) Use tools appropriate to the work. Makeshift tools, parts, and procedures are not recommended. (4) When servicing is performed together by two or more persons, take care to perform all work safely. (5) Do not work under the machine that is supported solely by a jack. Always support the machine by safety stands. (6) Do not touch the rotating or hot parts while the engine is running.

Do not smoke or allow flames or sparks in your working area. (2) To avoid sparks from an accidental short circuit, always disconnect the battery negative cable first and connect it last.
