CAUTION
• To prevent an accidental short circuit, attach the positive cable to the positive terminal before the
negative cable is attached to the negative terminal.
• Do not remove the battery cap while the engine operates.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, clean with water
immediately.
• Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen
becomes very explosive.
