Avoid breathing A/C R-134a refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved service equipment
to discharge R-134a systems.
Air conditioning systems are extremely sensitive to moisture and dirt. The importance of clean working conditions is extremely important, as the smallest
particle of foreign matter in an air conditioning system will contaminate the refrigerant, causing rust, ice or damage to the compressor. For this reason, all
replacement parts are sold in vacuum sealed containers and should not be opened until they are to be installed in the system. If, for any reason, a part has
been removed from its container for any length of time, the part must be completely flushed using only R-134a to remove any dust or moisture that may
have accumulated during storage. In cases of collision repairs where the system has been open for any length of time, the entire system must be purged
completely and a new receiver-dehydrator must be installed because the element of the existing unit will have become saturated and unable to remove
any moisture from the system once the system is recharged.
When making gauge connections, purge the gauge lines first by cracking the charging valve and allowing a small amount of refrigerant to flow through
the lines, then connect the lines immediately.
Cleanliness is especially important when servicing compressors because of the very close tolerances used in these units. Consequently, repairs to the
compressor itself should not be attempted unless all proper tools are at hand and a virtually spotless work area is provided.
BRAKE FLUID WARNING
Do not reuse any old brake fluid, as it has contaminants and contains water which lowers the boiling point of the fluid. Be careful not to spill any brake
fluid on any painted surfaces. If any brake fluid is spilled onto painted surfaces, immediately flood the area with lots of water.
FUEL PRESSURE RELEASE
Before working on the fuel system, disconnect the negative (-) terminal cable from the battery.
1. When disconnecting the high pressure fuel line, a large amount of gasoline may come out so observe these procedures:
a. Put a container under the connection.
b. Slowly loosen the connection.
c. Disconnect the connection.
d. Plug the connection with a rubber plug.
