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 certified service 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), make sure all valves on hoses and tanks are closed.
• Do not use this Recovery System in the vicinity of spilled or open containers of flammable substances (gasoline,
solvents, etc.).

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 mixtures of air and R134a have been shown to be combustible at elevated pressures.
These mixtures, if ignited, may cause injury or property damage. Additional health and safety information may
