PRECAUTIONS FOR VEHICLES EQUIPPED
WITH A CATALYTIC CONVERTER
CAUTION: If large amounts of unburned gasoline flow into
the converter, it may overheat and create a fire hazard. To
prevent this, observe the following precautions and explain
them to your customer.
1. Use only unleaded gasoline.
2. Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20
minutes.
3. Avoid spark jump test.
(a) Spark jump test only when absolutely necessary. Per-
form this test as rapidly as possible.
(b) While testing, never race the engine.
4. Avoid prolonged engine compression measurement.
Engine compression tests must be made as rapidly as
possible.
5. Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra
load on the converter.
6. Avoid coasting with ignition turned off and prolonged
braking.
7. Do not dispose of used catalyst(s) along with parts con-
taminated with gasoline or oil.
