[. . . ] A/C MANIFOLD GAUGE SET R134A 92649 ASSEMBLY AND OPERATING INSTRUCTIONS All technicians opening the refrigeration circuit in automotive air conditioning systems MUST be certified in refrigerant recovery and recycling procedures in compliance with Section 609 of the Clean Air Act Amendments of 1990. For additional information regarding ozone depletion and air conditioning service regulations, please visit EPA's website: http://www. epa. gov/ozone In addition, service of air conditioning systems can result in overfilling, creating a serious EXPLOSION HAZARD, if done by an untrained or inexperienced technician.

Copyright© 2004 by Harbor Freight Tools®. [. . . ] A running gasoline engine generates Carbon Monoxide; Carbon Monoxide is a colorless, odorless gas that can cause serious injury and death, if inhaled. Always keep hands and fingers away from the moving parts and hot parts of vehicle's engine. Make sure to read and understand all instructions and safety precautions as outlined in the vehicle manufacturer's manual for air condition servicing. Only qualified mechanics that are trained in servicing air conditioning systems should use this product. When warming up an engine in preparation for testing of the A/C system, make sure the vehicle's transmission is placed in "Park" and the emergency brake is applied. Refrigerant R-134a can cause severe frostbite if it comes in contact with the skin. Always follow the safety warnings and instructions provided by the manufacturer of R-134a refrigerant. Never disconnect any hose while the hose is under pressure. Pressurized R-134a refrigerant can cause severe injury. Use caution when opening an air conditioning system line or can of refrigerant. When testing, always place a towel around the service valves of the air conditioning unit and High and Low Pressure Couplers (20 and 21) of the A/C Manifold set. Keep refrigerant away from excessive heat as pressure in the container could increase enough to rupture the can. Never discharge refrigerant into the atmosphere. Always capture refrigerant into an approved recovery container (not included), and then dispose of properly. Contact your local Hazardous Waste Authority for disposal guidelines. Only use refrigerant in a manner consistent with the air conditioning system's repair manual. 3. 4. 5. 8. 9. Unpacking When unpacking, check to make sure the parts listed on page 8 are included.

By comparing the high side and low side pressure reading to the vehicle manufacturer's A/C system specifications, a probable faulty condition may be determined. The High Pressure Gauge (3) is used to measure compressor discharge pressure. The Low Pressure Gauge (5) is used to measure suction, or low side pressure. (See FIGURE 1 on page 6. ) The Red and Blue Thumb Handles (11) control the flow of refrigerant to and from the Yellow Refrigeration Charging Hose (18), also called the Service Hose. [. . . ] Check for cracked or broken parts, damaged Hoses (17, 18, 19), and any other condition that may affect safe operation. If a problem with the Set occurs, have it corrected before further use. Periodically, clean with a damp cloth using a mild detergent or solvent. When storing, keep the Set clean and dry. [. . . ]
