SAFETY IS ALWAYS THE FIRST PRIORITY! READ THE INSTRUCTIONS BEFORE USING For your safety and the safety of others, as well as to avoid any damage to the product and your vehicle, carefully read and make sure you fully understand this manual's safety instructions in its entirety. You must read the vehicle's service manual, the battery manufacturer's specific safeguards, and observe the stated precautions or instructions before and during any test or service procedure. ONLY OPERATE TESTS IN A WELL-VENTILATED AREA since the vehicle produces carbon monoxide (a toxic, poisonous gas, and particulate matter) when the engine is running.
ALWAYS WEAR APPROVED SAFETY EYE PROTECTION to prevent damage from sharp objects and caustic liquids. ALWAYS BE AWARE OF MOVING PARTS (such as coolant fans, pulleys, belts) since they spin or turn at high speeds when the engine is running. DO NOT TOUCH HOT ENGINE PARTS to prevent severe burns. The motor parts can get extremely hot when the engine is running. TURN THE IGNITION OFF BEFORE CONNECTING OR DISCONNECTING THE TOOL FROM THE BATTERY to prevent damage to the tester or the vehicle's electronic components. DON'T SMOKE NEAR THE VEHICLE when testing. Fuel and battery vapors are highly flammable. EN I 5
