F. UNIT STORAGE
Certain precautions must be taken if a mobile Diesel
Generator set is to be stored for a long period of time.
The unit must be stored in a dry location to prevent the
generator winding from drawing moisture. The unit
should also be thoroughly cleaned prior to storage.
For engine storage procedures consult your local Kubota
engine dealer. They have certain procedures that must
be followed in order to prevent engine damage, i.e.
cylinder rust and injector deterioration.
50 CYCLE (HZ) OPERATION
With a couple of minor changes these Mobile Diesel
Generators are capable of producing 50 hz power. Two
changes must be made.
A. The engine must be reduced to 1500 RPM governed
speed. Consult your local Kubota Service center for the
proper procedure for reducing the engine speed and
setting up the governor to operate at 1500 RPM.
B. The automatic volt/hertz regulator must also be reset
to operate at 50 HZ instead of the standard 60 HZ. This
is done by cutting the two leads marked HZ that come
out of the regulator. This will change the regulator for
60 HZ operation to 50 HZ operation. If it should become
necessary to change it back to 60 HZ, you would need to
splice the leads together again.
MAINTENANCE
The ultimate aim of a preventive maintenance program
is to maintain the equipment in optimum condition,
either in service or ready for service, for the maximum
amount of time during the useful life of the equipment.
The detection of faults before they develop into major
sources of difficulty will decrease the incidence of repair.
To this end, a regular schedule of cleaning and inspec-
tion will go far toward assuring trouble-free operation.
Personnel responsible for maintenance should set up a
schedule for inspection, and cleaning at intervals
calculated to keep the equipment in good condition. In
making up a schedule, keep the following in mind:
A. New equipment must be carefully monitored until
extended operation has demonstrated that it is perform-
ing satisfactorily.
B. Old equipment requires more frequent inspection
(and possibly servicing) than similar equipment that has
seen less service.
C. Time spent in cleaning, inspecting and correcting
minor defects before they become major troubles means
time saved in overhaul and repair.
PREVENTIVE MAINTENANCE
A. Daily Maintenance Checklist
** Oil level is between the L Low mark and the H
high mark on the dipstick. ** Fuel tank full of proper
grade of diesel fuel. ** Water and sediment drained from
water separator. ** Radiator filled with the proper
coolant mixture. ** Check air cleaner service indicator.
Change the filter element when the red indicator flag is
at the raised position ** Inspect for any fluid leaks
** Look for any loose or damaged parts
** Check belts for cracks or frays
** Check trailer hitch and safety chains for fitness
** Check tires for proper pressure
** Battery for proper fluid level.
** Generator control panel for loose or damaged parts.
** Unit for general appearance and cleanliness.
