Detection circuit
.....
This detects quantity of
oil,
sufficient or not, according to difference of electric
resistance across inner and outer electrodes.
@
Delay circuit
...........
This his prevents the sensor from making an unnecessary stop of the engine
by momentary lowering of the oil level due to the engine being slanted or
affected by vibration in spite of sufficient oil in the crankcase.
@I
Stopping circuit
......
This automatically stops the engine running.

CAUTIONS TO
BE
TAKEN ON HANDLING THE SENSOR
(1)
Oil sensor unit
0
Be sure not to damage each
wire.
Broken or short-circuited power supply wires and/or a ground-
ing wire in particular may lead to malfunction or breakdown.
@
The sensor is not interchangeable from engine to engine because the sensor is to be exclusively
installed individually in each engine employed.
(2)
Mounting and wiring of oil sensor unit
0
Although this has been designed to have enough antinoise properties in practical use,
do
not
route the sensor wirings in the vicinity of noise-generating sources such
as
ignition plugs or high
I
voltage
cords.
This may cause malfunction or breakdown.
@
Since capacity of power source is limited, current flown in the electronic circuit
of
the sensor is
kept as low as possible. Be sure
to
use terminals with
a
high contact reliability of more than that
of
tinned terminals.

Operation of oil sensor
@
If
operating with the engine kept tilted, oil surface inside of the engine varies and the correct oil
~
level can not to be detected which in turn obstructs the preventing function
of
engine seizure.
I
Operate the engine by keeping
it
level.
@
When starting the engine with an insufficient oil in the crankcase, engine starts once then
it
stops
j
automatically after it runs for
5
seconds.
i
@
When the engine has been stopped by the oil sensor, voltage remained in the electronic circuit
prevents the sensor from being restarted for
3
seconds after the engine stop. Try to restart the
~
engine after
3
seconds or more.
