2. Insert mains plug into AC source socket;
3. For disconnection, first of all pull out the mains plug from AC source socket, then disconnect the clamps or eyelet from battery pole.

Charging vehicle-mounted lead-acid battery:
1. Connect the red clamp to the Pos pole of battery, black clamp to the vehicle chassis and keep away from fuel pipe and battery(If battery's Pos pole grounded, then connect black clamp to Neg pole, red clamp to vehicle chassis and keep away from fuel pipe and battery);
2. Insert mains plug into AC source socket;
3. Before disconnection, first of all pull out the mains plug from AC source socket;
4. Then disconnect black clamp before red clamp
    (If battery's Pos pole grounded, then disconnect red clamp before black clamp)

• Never charge a damaged battery.
• Never charge a frozen battery.
• Never place the charger ventilation during charging.
• Always provide for charger on top of the battery when charging.
• Avoid covering the charger.
• A battery being charged could emit explosive gasses. Prevent sparks close to the battery.
  When batteries are reaching the end of their lifecycle internal sparks may occur.
• All batteries fail sooner or later. A battery that fails during charging is normally taken care of by the chargers advanced control, but some rare errors in the battery could still exist.
