MOTION HAZARDS
• Engine parts that are in motion and unexpected movement of a vehicle can injure or kill. When working near moving engine parts, wear snug fit
clothing and keep hands and fingers away from moving parts. Keep hoses and tools clear of moving parts. Always stay clear of moving engine
parts. Hoses and tools can be thrown through the air if not kept clear of moving engine parts.
• The unexpected movement of a vehicle can injure or kill. When working on vehicles always set the parking brake or block the wheels.
FUME HAZARDS
• FUMES, GASES, AND VAPORS CAN CAUSE DISCOMFORT, ILLNESS, AND DEATH! To reduce the risk of discomfort, illness, or death, read,
understand, and follow the following safety instructions. In addition, make certain that anyone that uses the equipment understands and follows
these safety instructions as well.
• Avoid breathing A/C refrigerant and lubricant vapor mist. Exposure may irritate eyes, nose, and throat. To remove R134a from the A/C system,
use service equipment certified to meet the requirements of SAE J2788--R134a recycling equipment. Additional health and safety information
may be obtained from refrigerant and lubricant manufacturers.
• Always perform vehicle service in a properly ventilated area. Never run an engine without proper ventilation for its exhaust.
• Stop the recycling process if you develop momentary eye, nose, or throat irritation as this indicates inadequate ventilation. Stop work and take
necessary steps to improve ventilation in the work area.
HEAT/FREEZING HAZARDS
• When under pressure, refrigerants become liquid. When accidentally released from the liquid state they evaporate and become gaseous. As they
evaporate, they can freeze tissue very rapidly. When these gases are breathed in, the lungs can be seriously damaged. If sufficient
quantities are taken into the lungs, death can result. If you believe you have exposed your lungs to released refrigerant, seek immediate medical
assistance.
• Refrigerants can cause frostbite and severe burns to exposed skin. Refrigerants are under pressure and can be forcibly sprayed in all directions if
carelessly handled. Avoid contact with refrigerants and always wear protective gloves and make certain other exposed skin is properly covered.
• Refrigerants can also severely injure or cause permanent blindness to unprotected eyes. Refrigerants are under pressure and can be forcibly
sprayed in all directions if carelessly handled. Avoid contact with refrigerants and always wear safety goggles.
EXPLOSION/FLAME HAZARDS
• Never recover anything other than the approved refrigerants as specified on the machine. Alternate refrigerants may contain flammables such as
butane or propane and can explode or cause a fire. Recovering alternate refrigerants will also void the warranty on your machine.
• For general safety reasons, at the end of the working day or in between services (when services do not immediately follow), see to it that all valves
on hoses and the machine are closed.

CAUTION: This equipment should be used in locations with mechanical ventilation that provides at least four air changes per hour or the
equipment should be located at least 18 inches (457 mm) above the floor, or the equivalent.
CAUTION: Do not pressure test or leak test R134a service equipment and/or vehicle air conditioning systems with compressed air. Some
