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 fast idle speed for more than
10
minutes
and at
idle speed for more than
20
minutes.
3.
Avoid spark jump test.
{a)
Perform spark jump test only when absolutely
necessary and as quickly as possible.
(b)
While testing, never race the engine.
4.
Avoid prolonged engine compression measurement.
Engine compression tests must be made as quickly as
possible.

load on the converter.

braking.

taminated with gasoline or oil.
