lamp on the front of transfer switch; (applicable only when the
transfer switch is equipped with indicating lamps or your
electrician has installed them). After sufficient time to assure
that power restoration isn’t temporary, return the transfer
switch to normal power (10 - 20 minutes).
9. Place the generator circuit breaker in “off” position. Do not
remove plug before opening the breaker.
10.Slowly reduce power take-off speed to a minimum and
disengage the power take-off. Some tractors have a brake on
the power take-off that stops the shaft instantly. Stopping the
alternator rotor instantly from rated speed may result in a
broken shaft or other drive line failures.
WARNING: Personal Injury
Never try to manually stop the generator. Always let it
coast until it stops.
11.Shut off the engine.
12.Disconnect drive shaft (tumbling bar) power take-off end
first, then generator end.
13.Exercise PTO generator for one hour under load at least
twice a year.
STORAGE & MAINTENANCE
If the generator is mounted on an off-highway trailer, such as
the Winco trailer, it should be stored in a garage, barn or
machine shed in a dry and clean location. The generator
should be covered with a tarpaulin to prevent the entrance of
dust, chaff, and/or moisture.
MAINTENANCE REQUIREMENTS
LUBRICATION
1. Check the generator gear case oil level before each use of
the generator. See Figure 4. Maintain the oil level at oil level
plug height. The generator is shipped with lubricant in the
gear case. Specifications for gear case lubricant are: API
Service: GL-5 EP Rated, Grade: SAE 85W-90-140, Amount: 1
pint. The following kinds of oil are recommended for use in
the generator gear case:
Mobil SAE 85W90-140 API Service GL-5
Sunoco/DX XL80W90-140
Kendal Three Star 85W-140
Amoco 85W140 or equivalent
CAUTION: Equipment Damage
Do not overfill generator gear case. Overfilling causes
overheating and oil seal failure.
Change the oil every six months or at least once a year.
Change it more often if you use the generator in bad weather.
Use the following procedure to change generator gear case
oil
a. Remove gear case breather. Soak breather in cleaning
solvent, then allow it to dry.
b. Remove oil level check plug.
c. Remove the oil drain plug, drain the oil into a clean oil
resistant container, 1 quart or larger. Check the oil for
metal. Fine metal dust in the oil does not indicate
trouble, but metal chips do. Dismantle the gear case
and look for damaged gears if you find metal chips in
the oil.
d. Replace the oil drain plug. Refill the gear case through
the breather port with new oil of the recommended type.
Fill the case up to oil level check plug height. (It will take
about 1 pint.)
2. The generator bearings are factory lubricated and sealed,
and require no further lubrication.
3. The splined generator input shaft should be cleaned and
lubricated with a thin film of grease before and after each use
of the generator.
4. The drive shaft (tumbling bar) requires greasing. Keep the
universal joints in the coupling shaft free from grease and dirt
buildup.
NOTE: Do not over lubricate the universal joints.
CLEANING
1. Inspect for loose or broken wiring connections. Make sure
that wiring connections are not loose at the generator end,
circuit breakers, and receptacles.
2. Do not allow dirt or chaff to collect in the interior of the
generator or the ventilation openings. Inspect for indication of
the entrance of mice or insects into the generator. The inlet
and outlet openings are louvered, but possible damage to the
louvers could occur. Mice can destroy the generator winding.
WARNING: Equipment Damage
DO NOT CLEAN THE GENERATOR WHILE IT IS RUNNING.
CAUTION: Equipment Damage
Most electrical equipment in North America operates
satisfactorily at frequencies between 59 and 61 Hz (cycles
per second). Operating the generator at frequencies
outside that range may cause damage to the generator and/
or to electrical equipment driven by the generator.
