SAFETY SERVICING AND REPAIRING
(1) Before working on the machine:
• Park the machine on a firm and level ground, and set the parking brake.
• Lowe ....the implement or mower to the ground.
• Stop the engine, and remove the spark plug cap and the key.
• Disconnect the battery's ground cable.
• Clean the work area and machine.
(2) Do not work on the machine while under the influence of alcohol, medication, or other substances or
while fatigued.
(3) Do not wear a necktie, scarf, necklace, loose or bulky clothing when you work near machine tools or
moving parts.
(4) Use tools appropriate to the work. Makeshift tools, parts, and procedures will not make good repairs.
(5) When servicing is performed together by two or more persons, take care to perform all work safely.
(6) Do not work under the machine that is supported solely by a jack. Always support the machine by safety
stands.
M7580·M8580·M9580 WSM,11231 SAFETY INSTRUCTIONS
(7) If the engine must be running to do same work, make sure the area is well ventilated. Never run the
engine in a closed area. The exhaust gas contains poisonous carbon monoxide.
(8) Do not touch the rotating or hot parts and high tension cords while the engine is running.
(9) Fuel is extremely flammable and explosive under certain conditions. Do not smoke or allow flames or
sparks in your working area.
(10) To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable first and
connect it last.
(11) Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get medical attention immediately.
(12) Battery gas can explode. Keep sparks and open flame away from the top of battery, especially when
charging the battery.
(13) Never remove the radiator cap while the engine is running, or immediately after stopping. Otherwise,
hot water will spout out from radiator. Wait for more than ten minutes to cool the radiator, before
removing the cap.
(14) Escaping fluid (fuel or hydraulic oil) under pressure can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines. Tighten all connections before applying pressure.
(15) Do not start the engine by shorting across starter terminals.
(16) Unauthorized modifications to the machine may impair the function and / or safety and affect machine
life.
(17) Do not alter or remove any part of machine safety system.
(18) Keep a first aid kit and fire extinguisher handy at all times.
