Specific Safety Rules for the Battery Charger Maintain labels and nameplates on the Battery Charger. These carry important information. If unreadable or missing, contact Harbor Freight Tools for a replacement. Always wear safety impact eye goggles and heavy work gloves when using the Battery Charger.
When unpacking, check to make sure that the item is intact and undamaged. If any parts are missing or broken, please call Harbor Freight Tools at the number on the cover of this manual as soon as possible.
Batteries draw as much power as they need from the charger. The charger does not force current into the battery. When a battery is close to dead or very low charged, it will want to draw more current. When a dead or low battery is charged, the charger’s ammeter will register at the high end.
For a quick charge assist to enable starting the engine, charge for 5 to 10 minutes. For a full charge, leave the Battery Charger running. If the charger is in manual mode, it must be monitored and shut off when the battery is charged; NEVER leave a battery unattended while charging.
When finished charging the battery, push the Function Switch to the Off position and unplug the Power Cord (3) from the electrical outlet. 10. Disconnect the Cable Clamps from the battery. The ammeter shows how much charging current is drawn from the charger (to the battery).

Before each use, inspect the general condition of the Battery Charger.
