SPECIFICATIONS
GENERAL SPECIFICATIONS VEHICLE-SPEED SENSOR (REED-TYPE SWITCH)
The vehicle-speed sensor functions to substitute pulse signals
for the rotations (vehicle speed) of the transmission’s output
gear;/ t i is located within the speedometer.
Pulse signals are generated when the speedometer cable
rotates.
AUTbMATlC FREE-WHEELING HUB INDICATOR
CONTROL UNIT
The control unit is located at the upper part of the right cowl
side.
The control unit is composed of the pulse-detection circuit
(which receives the input signals from the pulse generator),
the vehicle-speed-detection circuit (which receives the input
signals from the vehicle-speed sensor), the lock-discrimination
circuit (which, based on both of these input signals, judges the
condition of the automatic free-wheeling hub ‘and then trans-
mits indicator output signals to the memory circuit), and the
memory circuit (which “memorizes” the indicator output
signals from the lock-discrimination circuti).

24-28 AIR-CONDITIONING-Safety Precautions
SAFETY PRECAUTIONS N24PAAB
SAFETY PRECAUTIONS
I
The refrigerant used in all air-conditioning installations is R-12. It is transparent and colorless in both the liquid and
vapor state. Since it has a boiling point of -29.8T (-21.7”F). at atmospheric pressure, it will be a vapor at all normal
temperatures and pressures. The vapor is heavier than air, non- flammable, and nonexplosive. It is nonpoisonous
except when it is in direct contact with open flame. It is noncorrosive except when combined with water. The
following precautions must be observed when handling R-12.
Caution
Wear
safety goggles when servicing the refrigeration system.
R-12 evaporates so rapidly at normal atmospheric pressures and temperatures that it tends to freeze anything it
contacts. For this reason, extreme care must be taken to prevent any liquid refrigerant from contacting the skin and
especially the eyes.
Always wear safety goggles when servicing the refrigeration part of the air- conditioning system. Keep a bottle of
sterile mineral oil handy when working on the refrigeration system. Should any liquid refrigerant get into the eyes,
use a few drops of mineral oil to wash them out. RI12 is rapidly absorbed by the oil. Next, splash the eyes with
plenty of cold water. Call your doctor immediately even though irritation has ceased after treatment.
Caution
Do not heat R-12 above 52°C (125°F).
In most instances, moderate heat is required to bring the pressure of the refrigerant in its container above the
pressure of the system when charging or adding refrigerant. A bucket or large pan of hot water not over 52°C
(125°F) is all the heat required for this purpose. Do not heat the refrigerant container with a blow torch or any other
means that would raise temperature and pressure above this temperature. Do not weld or steam clean on or near
the system components or refrigerant lines.
Caution
Keep R-12 containers upright when charging the system.
When metering R-12 into the refrigeration system, keep the supply tank or cans in an upright position. If the
refrigerant container is on its side or upside down, liquid refrigerant will enter the system and damage the
compressor.
Caution
Always work in a well-ventilated room.
Good ventilation is vital in the working area. Always discharge the refrigerant into the service bay exhaust system
or outside the building. Large quantities of refrigerant vapor in a small, poorly ventilated room can displace the air
and cause suffocation.
Although R-12 vapor is normally nonpoisonous, contact with an open flame can cause the vapor to become very
poisonous. Do not discharge large quantities of refrigerant in an area having an open flame. A poisonous gas is
producted when using the flame-type leak detector. Avoid inhaling the fumes from the leak detector.
Caution
Do not allow liquid refrigerant to touch bright metal.
Refrigerant will tarnish bright metal and chrome surfaces, and in combination with moisture’can severely corrode
all metal surfaces.
