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 John Deere 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 detec-
tion 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 inspection 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 sched-
ule, 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.
** Check the generator control panel for loose or dam-
aged parts.
** Check the unit for general appearance and cleanliness.
