Do not use the power tool if the Power Switch does not turn it on or off. Any tool that cannot be controlled with the Power Switch is dangerous and must be replaced. [. . . ] When placing the Battery Tester in the vehicle (on the frame, engine, or fender), take special care that the metal housing of the Battery Tester does not come in contact with either terminal of the battery or other electrical connections. Do not drop the Battery Tester as it may affect proper operation. Do not smoke or have open flames near the battery. Reversing Battery Tester Cable Clamps on the battery will damage the tester. Do not connect the Battery Tester to the battery while the battery is being charged. Do not touch the cooling vents on the Battery Tester immediately after testing the battery. They become very hot. UNPACKING When unpacking, check to make sure that the product is intact and undamaged. If any parts are missing or broken, please call Harbor Freight Tools at the number at the bottom of the page as soon as possible. SKU 93784 For technical questions, please call 1-800-444-3353. Page 4 OPERATING INSTRUCTIONS (A) (D) (C) (B) Testing the Battery Undercharged lead-acid batteries will freeze during cold weather. To help ensure a good connection, clean battery terminals with a solution of baking soda and water, and wipe the battery terminals with a cloth to remove any dirt and grease. Connect the red (positive) Cable Clamp (A) to the positive terminal (+) on the 6 or 12 V lead-acid battery. (See photo above. ) Connect the black (negative) Cable Clamp (B) to the negative terminal (­) on the battery. Turn clamps slightly to ensure a good connection. With the clamps connected, the tester's gauge will show the battery's current charge. If it is less than 12 V on a 12 V battery (or 6 V on a 6 V battery), disconnect the battery and recharge before testing. If recharging will not bring the reading above the appropriate voltage (noted above), the battery is defective. If it shows no reading, verify that the tester is connected properly. If the tester is connected properly, the battery is defective. Press (and hold) the Toggle Switch (C) for at least 5 seconds to simulate an actual load on the battery. View the Meter Display (D) and read the battery condition. Refer to the "Battery Condition Analysis" section on the next page. Release the Toggle Switch (C) and remove the Cable Clamps from the battery. 2. 7. SKU 93784 For technical questions, please call 1-800-444-3353. Page 5 Testing the Charging System Note: The engine should be at normal operating temperature during this test. [. . . ] View the Meter Display (D) and read the voltage. A reading of 9 volts or less indicates excessive current draw for a 12 V system. This may be due to a poor connection, a failing starter, or a battery of insufficient size for the motor. Caution: DO NOT press the Toggle Switch (C) during this test. INSPECTION, MAINTENANCE, AND CLEANING 1. Clean the outside of the unit with a damp cloth. [. . . ]
