• DO NOT use this product if it is damaged or malfunctions. Repair or replace damaged components before further use.
• ALWAYS use with proper personal protective equipment such as a dust mask, goggles, and work gloves in a well-ventilated place, as these refrigerants can irritate your eyes, nose, throat, and skin or cause frostbite, heart arrhythmia, unconsciousness, and even death. Further, operating your vehicle in a closed environment may result in carbon monoxide poisoning and other problems. If you begin to develop symptoms such as headaches, dizziness, or nausea during use of this product, turn off your vehicle and get fresh air IMMEDIATELY. Do not continue work until the vehicle has been moved to an area with better ventilation.
• Use EXTREME caution when disconnecting the hoses after use, as they may still contain some refrigerant under pressure.
