SECTION 8
Countermeasures
* Check the fuel tank and fuel filter.
* Remove water, dirt and other
impurities.
* As all fuel will be filtered by the filter, if
there should be water or other foreign
matters on the filter, clean the filter
with kerosene.
* If air is in the fuel filter or injection
lines, the fuel pump will not work
properly.
* To attain proper fuel injection
pressure, check carefully for loosened
fuel line coupling, loose cap nut, etc.
* Loosen air vent screws stop fuel filter
and fuel injection pump to eliminate all
the air in the fuel system.
* Change grade of oil according to the
weather (temperature.)
* Charge battery.
* In winter, always remove battery from
machine, charge fully and keep
indoors. Install in machine at time of
use.
Countermeasures
* Check fuel system.
* Check lubricating oil system.
* Check to see if lubricating oil filter is
working properly.
* Filter element deposited with
impurities would cause poor
lubrication. Change element.
* Clean the element every 100 hours of
operation.
* Do not use poor quality fuel as it will
cause wear of the pump. Only use No.
2-D diesel fuel. (See "FUEL" in
"PERIODIC SERVICE" section.)
B When engine suddenly stops
Cause
Lack of fuel
Bad nozzle
Moving parts are
overheated due to
shortage of
lubrication oil or
improper
lubrication.
B When color of exhaust is especially bad
Cause
Fuel is of extremely
poor quality.
Nozzle is bad.
B When engine must be stopped immediately
