CAUTION
If plug of different maker or
different heat value is used, it
causes unsatisfactory engine
starting, inadequate engine revol-
ution and output deterioration.
The spark plug must be securely
tightened. An improperly tightened
plug can become very hot and
possibly damage the engine.
To install a spark plug, turn it in as
far as possible with your fingers,
then tighten it with a wrench.
Do not overtighten or cross thread
the spark plug or the aluminum
threads of the cylinder head will be
damaged.Do not allow contaminants
to enter the engine through the spark
plug hole when the plug is removed.
<DEALING WITH POOR STARTING>
When the starter doesn't work during
driving in winter times or in a repeated short
distance, use the suitable spark plug for this
driving condition.
Poor starting may happen when nonstop
driving in low speed, even though we
produce standard plug.
In case starter isn't working well in driving
repeatedly in a short distance or in an area
with many traffic signals, use the CR7EH-9
plug instead of standard plug CR8EH-9
