  2. Plug in the Charger: Plug the AC power cord into a standard 120V outlet.
  3. Set Charge Rate Selector: Turn the Charge Rate Selector Switch to the 'Engine Start' position (12V 250A).
  4. Crank the Engine: Attempt to start the engine. If it does not start immediately, wait a few minutes before trying again to allow the battery to receive some charge.

Battery Charging Procedure

  1. Connect the Clamps: Connect the red positive (+) clamp to the positive battery terminal and the black negative (-) clamp to the negative battery terminal.
  2. Plug in the Charger: Plug the AC power cord into a standard 120V outlet.
  3. Select Charge Rate: Use the Charge Rate Selector Switch to choose the desired charging mode:
    • 10A 12V: For standard charging of 12V batteries.
    • 25A 6V/12V Boost: For faster charging of deeply discharged 6V or 12V batteries.
    • 50A 12V Boost: For rapid charging of deeply discharged 12V batteries.
  4. Set Timer: Rotate the Timer knob to the desired charging duration (up to 135 minutes). The unit will automatically stop charging when the timer expires.
  5. Monitor Charging: Observe the analog ammeter to monitor the charging current. The current will gradually decrease as the battery charges.
  6. Disconnect: Once charging is complete or the timer expires, unplug the AC power cord from the outlet first, then disconnect the negative (-) clamp, followed by the positive (+) clamp.
