OPERATION
j Cold engine J
On the cold engine the wax element changes
(reduces) its volume according to the ambient
temperature.
In this state the starter plunger is at the top,
thereby opening the starter plunger.

J Running engine J
When the engine is started, the heated P.T.C.
thermistor expands the wax element, gradually
pushing the starter plunger and controlling the
opening of the starter passage. The further heated
thermistor expands the wax element to a com-
plete extent, thereby fully closing the starter
passage.
This in turn causes the engine r.p.m, to change
(be reduced) with time, finally coming to specified
idling.
The wax element expands during the ride as well
by means of the P.T.C. thermistor, thereby keep-
ing the starter passage fully closed.
