CHECKING
PROCEDURE
/-
When the engine can not be started, supply oil up to the maximum oil level, and pull the recoil keeping the
engine in the horizontal position. Engine
oil
is
supplied up till the maximum level; but it doesn't start yet,
please check the engine
in
the following manner.
1)
Oil Level Sensor Checking (See
Fig.
46.)
Disconnect the sensor from the controller, and check with a tester continuity between the sensor lead
wire (yellow) and the grounding wire of the engine.
When there is
no
continuity under the condition that the oil has been supplied up to the specified level
(about
280
cc), the oil level sensor is normal.
If
there
is
continuity, replace it with a new one.
When there is continuity under the condition that the
oil
level is below the specified one
(200
cc), the
sensor
is
normal. If not, replace the sensor with a new one.

2)
Oil Level Controller Checking (See Fig.
47)
Disconnect the sensor from the controller (don't
disconnect the stop button
from
the controller),
and start operation of the stop switch after set-
ting rpm
of
the engine at more than 1,200 rpm.
(Don't continue depressing it, and restore
it
to
the normal position soon.)
Warning lamp is lit in a few seconds and the
engine is stopped, the controller is normal. If
the
oil
warning lamp is not lit and the engine is
stopped, replace the warning lamp with a new
one.
If
the engine does not stop in a few seconds
(about 2 seconds), inner section of the controller
is defected,
so
replace it with
a
new one.
