executor for a few times for feeling whether the motion is smooth.

which the dirt may be accumulated. Open the sight glass cover on the
mid of governor to check whether the fasteners or pins attached
coupling to the rack of oil pump are loosened, if so, timely tighten it.

5.12.7 Precautions
a.
The matched speed sensor is only used for electronic governor rather
than other speed measuring devices.
b.
To ensure the safety of engine system, the governing function of
electronic governor can
’
t be replaced by the overspeed protection
function which should be independently installed.
c.
The emergency-stopping executor of overspeed protection device
should be independent and can
’
t be replaced by the electromagnetic
executor.
d.
Each time of starting engine, please ensure the “idling/rating”
speed
switch is at “idling” position.
e.
The potentiometers of controller have already well set at delivery and
should not be adjusted by the non-professional.
f.
With engine not running, it is not allowed to adjust (specially increase)
the rated speed of the controller, or to set the potentiometer or trimmer
potentiometer. The set speed should not be too high, which could lead
to overspeed at the beginning of engine startup.
g.
If the engine after being sealed for long time is to be reused or is
started at low temperature, push the rocker arm of executor for a few
times for feeling whether the motion is smooth. If there is stuck
phenomenon, do not start engine.
h.
If the engine after being sealed for long time is to be reused, before
startup, shortly connect the two probes of controller and then executor
should output max amount of fuel. The executor pointer should return
back to zero the moment the two probes are disconnected. Otherwise,
timely find out the cause, do not start engine rashly.
