Preventive Maintenance<br />
WARNING! Batteries can kill or injure you<br />
severely. They contain acid, produce poisonous<br />
and explosive gases, and supply levels of electric<br />
current high enough to cause burns. A spark<br />
or flame near a battery on charge may cause it to<br />
explode with great force.<br />
To help reduce the risk of personal injuries, follow these<br />
guidelines carefully when recharging a battery:<br />
• Before attempting any service in the electrical installation,<br />
disconnect the battery negative cable.<br />
• Allow no sparks or open flame anywhere near the charging<br />
area.<br />
• Charge a battery only in a well-ventilated area, such as<br />
outdoors or in a fully open garage which contains no pilot<br />
lights or other flames. Gases generated during the<br />
charging process must be allowed to escape.<br />
• Maintain the full level of electrolyte in the batteries. This<br />
reduces the volume of gas in the cells. The electrolyte<br />
level should always be between 0.4–0.6 in. (10–15mm)<br />
above plates. Fill with distilled water only. After distilled<br />
water has been added, wait at least a half hour to<br />
measure solution density (specific gravity). The specific<br />
gravity should be between 1.258–1.265 or the electrolyte<br />
level within “MIN” and “MAX” marks.<br />
Electrical System<br />
• When fast charging, remove the battery caps so pressure<br />
does not accumulate.<br />
• Always make sure the battery charger is OFF before<br />
connecting or disconnecting the cable clamps.<br />
• To avoid short circuits and damage to yourself or the<br />
vehicle, never place metal tools or jumper cables on the<br />
battery or nearby. Metal that accidentally comes in contact<br />
with the positive battery terminal or any other metal<br />
on the vehicle (that is in contact with the positive terminal),<br />
could cause a short circuit or an explosion.<br />
Charging Reminders<br />
• Use protective eyewear.<br />
• Keep all batteries away from children.<br />
• Never reverse battery poles.<br />
• Never attempt to place the vehicle in motion, or run the<br />
engine with batteries disconnected.<br />
• Keep the battery clean and dry.<br />
• Look for any signs of damage.<br />
WARNING! Never use a metallic funnel to add<br />
distilled water. It could come in contact with a<br />
terminal, creating a short circuit, resulting in<br />
death, severe personal injury or damage to your<br />
vehicle.<br />
