SAFETY CAUTIONS Caution Handling of Caution How to handle battery emergencies Handle the battery with care Batteries emit hydrogen and oxygen gases, both of which are flammable. Never use open fire or generate sparks near the battery. Otherwise, these gases may ignite and explode. Do not use the battery if the electrolyte level has dropped below the minimum line. Otherwise, the battery may explode. Be careful not to inadvertently place a metal object such as tool between the battery terminals. Always disconnect the negative (-) terminal first, then the positive (+) terminal, from the battery. Always connect the positive (+) terminal first, then the negative (-) terminal, to the battery.

Recharge the battery in a well ventilated place, with all battery plugs removed. The battery terminals should have a positive connection. Loose terminals can generate sparks, possibly causing the battery to explode. Before servicing or performing electric welding on the electrical/electronic system, position the battery switch in the OPEN/OFF position or disconnect the negative (-) terminal of the battery to isolate the electrical/electronic circuit. The battery electrolyte contains dilute sulfuric acid. Incorrect handling may lead to loss of eyesight or burn. Never drink battery electrolyte.

Wear protective goggles and rubber gloves when maintaining the battery (replenishing, recharging, etc.). If your skin or clothing has come into contact with battery electrolyte, immediately wash the affected area with plenty of water and then thoroughly clean with soap. Should your eyes come into contact with battery electrolyte, loss of eyesight may result. Immediately wash your eyes with plenty of fresh water and seek medical attention immediately. Should you inadvertently drink battery electrolyte, repeatedly gargle with plenty of water and then drink plenty of water. Seek medical attention immediately.

Engine overheat - Idle to cool down, then stop the engine In the event of engine overheat, do not stop the engine immediately. Doing so may cause the coolant temperature to rise quickly and the engine may seize. Instead, run the engine at low idle for a while to cool it down. Then, stop the engine. Do not attempt to replenish coolant for a while after the engine is stopped. Otherwise, the cylinder head etc., which may still be hot, is cooled down rapidly and may break. Wait until the engine is sufficiently cold and then top up slowly.

Never restart the engine after a sudden stop unless the cause is eliminated If the engine has suddenly stopped with some alert signals, do not restart immediately. Otherwise, the engine may seriously become damaged. Locate and eliminate the cause before restarting. Stop the engine immediately upon oil pressure drop If the oil pressure has dropped, immediately stop the engine. Otherwise, bearings etc. may seize. Inspect the oil system and components. Stop the engine immediately upon broken fan belt If the fan belt has broken, immediately stop the engine. Otherwise, the engine will overheat. Also, coolant vapor will gush out from the reserve tank and radiator and you may get burned. 0 - 6
