NOTE: 

Do not over lubricate the universal joints.

Check the generator gearcase oil level before each use of the 

generator. Maintain the oil level at the oil level plug height. The 

generator is shipped with lubricant in the gearcase. Specifications for 

the gearcase lubricant are:

API Serice: GL-5

Grade: SAE 85W-90-140

Amount: 0.85 Pints

The following kind of oil are recommended for use in the generator 

gearcase: Mobile SAE 85W-90-140 API Service GL-5, Sunonco/

DX XL80W90-140, Kendal Three Star 85W-140, Amoco 85W140 or 

equivalent.

CAUTION: EQUIPMENT DAMAGE

Do not overfill generator gearcase. Overfilling causes overheating and 

oil seal failure.

Change oil at least once every twelve months or 150 hours of 

operation. Change it more often if you use the generator in bad 

weather. Use the following procedure to change generator gearcase oil:

1. Remove gearcase breather. Soak breather in cleaning solvent, then 

  allow to dry.

2. Remove oil level check plug.

3. 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

MAINTENANCE

General  Information

The main components of the generator are: armature, field

coils,  cooling  fan,  brushes,  brush  holder  assembly,  end

brackets, and rectifier.  Before performing any maintenance

on the generator, isolate and/or disable the drive system so

the unit can not be accidentally started while being repaired.

The  troubleshooting  chart  lists  various  symptoms  of  poor

generator  operation  with  possible  causes  and  the  appro-

priate corrective action. You will need a volt-ohm meter or

test light to check some of the causes. For some of the

other causes you will need to check generator speed. To

check generator speed you can use a frequency meter, a

tachometer, or a 120V-60Hz electric clock and a correctly

operating wrist watch. (Run the electric clock on generator

power  and  compare  the  clock’s  second  hand  movement

with that of the wrist watch. They should run at the same

speed. If clock runs faster, generator speed is too high,

and vice versa.)

CAUTION: Equipment Damage

Most electrical equipment in North America operates

satisfactorily at frequencies between 58.5 and 62 Hz

(cycles per second.) Operating the generator at frequen-

cies outside that range may cause damage to the genera-

tor and/or to electrical equipment driven by the generator.

Periodical  Maintenance

Service/maintenance items include periodic external physi-

cal inspection for missing hardware or damage to mounting

or drive system and checking the oil level in the gear case.

It is recommended that the generator be operated at least

monthly under normal loads to familiarize operators with the

procedures and controls as well as to dry out any accumu-

lated condensation or other moisture in the generator elec-

trical  windings.    The  maintenance  and  service  attention

invested will insure getting the peak performance that was

designed into the unit.

Routine  preventive  maintenance  minimizes  costly  repairs

and generator down-time. Before each use, inspect the

generator: gear case oil level should be correct, cooling

vents and screens should be clear, and generator mount-

ing hardware should be tight. Clean and inspect the

generator after storing it for long periods, and after using

it in extremely dusty conditions or in severe weather, such

as  rain  or  blowing  snow.

Lubrication

The generator bearings are factory lubricated and sealed,

and require no further lubrication.

The generator input shaft should be cleaned and lubricated

with a thin film of grease before installing the drive shaft and

each time it is removed.

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.

Check the generator gear case oil level before each use of

the generator. Maintain the oil level at oil level plug height.

(See page 6 for oil level plug location.) The generator is

shipped with lubricant in the gear case. Specifications for

gear case lubricant are:

API Service: GL-5

Grade: SAE 85W-9O-140

Amount: 2 pints

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 at least once every six months. Change it

more often if you use the generator in bad weather. Use the

following procedure to change generator gear case oil:

1. Remove gear case breather. Soak breather in cleaning

solvent, then allow it to dry.

2. Remove oil level check plug.

3. 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.

4. 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 2 pint.)

5. Replace the oil level check plug.

6. Replace the breather.

Cleaning and Inspection

Use a vacuum cleaner or dry low pressure compressed air

(regulated at 25-35 PSI) to clean the generator periodically.

WARNING

DO NOT CLEAN THE GENERATOR WHILE IT IS RUNNING.

Proceed  as  follows:

MAINTENANCE

GENERAL INFORMATION

The main components of the generator are: rotor and stator assembly, 

cooling fan, brushes, brush holder assembly, end brackets. Before 

performing any maintenance on the generator, isolate and/or disable 

the drive system so the unit can not be accidentally started while being 

repaired.

The trouble shooting chart lists various symptoms of poor generator 

operation with possible causes and the appropriate corrective action. 

You will need a volt-ohm meter or test light to check some of the 

causes. For some of the other causes you will need to check generator 

speed. To check generator speed, you can use a frequency meter, a 

tachometer, or a 120V-60Hz electric clock and a correctly operating 

wrist watch (run the electric clock and a correctly power and compare 

the clock’s second hand movement with that of the wrist watch. They 

should run at the same speed. If the clock runs faster, generator speed 

is too high, and vice versa).

CAUTION: EQUIPMENT DAMAGE

Most electrical equipment in North America operates satisfactory at 

frequencies between 58.5 and 62 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.

PERIODICAL MAINTENANCE

Service/maintenance items include periodic external physical 

inspection for missing hardware or damage to mounting or drive 

system and checking the oil level in the gearcase. It is recommended 

that the generator be operated at least monthly under normal loads to 

familiarize operators with the procedures and controls as well as to dry 

out any accumulated condensation or other moisture in the generator 

electrical windings. The maintenance and service attention invested will 

ensure getting the peak performance that was designed to the unit.

Routine preventative maintenance minimizes costly repairs and 

generator down-time. Before each use, inspect the generator: gearcase 

oil level should be correct, cooling vents and screens should be 

clear, and generator mounting hardware should be tight. Clean and 

inspect the generator after storing it for long periods, and after using 

it in extremely dusty conditions or in severe weather, such as rain or 

blowing snow.

LUBRICATION

The generator bearings are factory lubricated and sealed, and require 

no further lubrication.

The generator input shaft should be cleaned and lubricated with a 

thin film of grease before installing the drive shaft and each time it is 

removed.

The drive shaft (tumbling bar) requires greasing. Keep the universal 

joints in the coupling shaft free from grease and dirt build-up.
