Checking the Operation
of the Diesel Engine
2-3.1
Low-pressure alarm system.
The diesel engines have a low-
pressure sensor system where if the
oil pressure drops too low, the sensor
will shut the engine off. The purpose
of having this system is to ensure
that the engine does not seize up. If
there is not enough oil in the engine,
the temperature of the oil will be
raised too high. On the contrary, if
there is too much oil in the engine,
the engine oil can slow the engine
down considerably. (NOTE: The 2 GF-L
model cannot automatically stop
itself.)
2-3.2
How to open the case door/cover
(1) Open the case door: turn the
handle counterclockwise and open
the door. Do these checks daily.
(2) Loosen the outer cover bolt of
the air filter and outer cover of the oil
nozzle, and then check the air filter.
(3) Check the outer cover of the oil
nozzle. Loosen the butterfly nut and
open the outer cover.
2-3.3 Engine Break In
When you purchase a brand new
engine, the engine must be properly
broken in. The break in period is about
20 hours.
(1) Avoid overloading the engine when
brand new.
(2) Change the engine oil according
to specifications. An oil change for a
brand new engine is about 20 hours
or every month, an older engine, the
oil change is about 100 hours or three
months.
