Self-exciting generators respond to severe overload-

ing differently than utility power. When overloaded,

the engine is not able to supply enough power to

bring the electric motor up to operating speed. The

generator responds with high initial starting current,

but the engine speed drops sharply. The overload

may stall the engine. If allowed to operate at very

low speeds, the electric motor starting winding will

burn out in a short time. The generator winding

might also be damaged.

CAUTION: EQUIPMENT DAMAGE

RUNNING THE GENERATOR SET UNDER

THESE CONDITIONS MAY RESULT IN DAMAGE

TO THE GENERATOR STATOR AS WELL AS THE

MOTOR WINDING.

The heavy surge of current required for starting

motors is required for only an instant. The genera-

tor will not be damaged if it can bring the motor up

to speed in a few seconds of time. If difficulty is

experienced in starting motors, turn all other electri-

cal loads off and if possible reduce the load on the

electric motor.

PREPARING THE UNIT

UNPACKING

CAUTION: EQUIPMENT DAMAGE

THIS UNIT HAS BEEN SHIPPED

WITHOUT OIL.

Failure to maintain the engine oil at the proper level

will result in serious engine damage.

When you unpack your new engine-generator set be

sure to remove all the information sheets and manu-

als from the carton.

1. This generator-set was in good order when

shipped. Inspect the generator-set promptly after

receiving it. If any damage is noted, notify the trans-

portation company immediately; request proper pro-

cedures for filing a “concealed damage” claim. Title

to the equipment and responsibility for filing a claim

rests with you when a generator-set is sent F.O.B.

shipping point. Only you can legally file a claim.

2. Before proceeding with the preparations of your

new generator-set for operation, take a couple of

minutes to insure the unit you have received is the

correct model and review the specification pages in

this manual to insure that this unit meets your job

requirements.

LUBRICATION

Before starting the engine, fill the crankcase to the

proper level with a good quality oil. The recom-

mended grade of oil and quantity of oil required is

listed in the engine operator’s manual and under the

service tab in this manual. This unit was shipped

with most of the oil removed. The engine normally

holds 57 and 58 ounces of oil. Since there is some

trapped oil in the engine, when filling the crankcase

the first time use the dipstick to ensure that you do

not over fill the crankcase. The blow-up shows the

full oil level mark on the dipstick.

Oil is added to the engine by removing the oil fill cap

and adding oil at this point. After filling the crank-

case to the proper level, be sure you properly tighten

the oil fill cap. NOTE: This engine generator must

be on a level surface before you check or add oil to

the system.

The necessity of using the correct oil, and keeping

the crankcase full cannot be overemphasized. En-

gine failures resulting from inadequate or improper

lubricant are considered abuse and not covered by

the generator or engine manufacturer’s warranty.

Oil Recommendations

Outdoor temperatures determine the proper oil

viscosity for the engines. Use the chart to select the

best viscosity for the outdoor temperature range

expected.

Use 4-stroke motor oil that meets or exceeds the requirements for
API service category SJ or later (or equivalent). Always check the
API service label on the oil container to be sure it includes the
letters SJ or later (or equivalent).

Check the engine oil level with the engine stopped and in a level
position.

Start the engine and let it idle for 1 or 2 minutes. Stop the engine
and wait for 2 or 3 minutes.

Remove the oil level dipstick and wipe it clean.

Fully insert the oil level dipstick, then remove it to check the oil
level.

If the oil level is low, remove the oil filler cap, and fill with the
recommended oil to the upper limit mark on the oil level dipstick.

Reinstall the oil level dipstick and oil filler cap.

The Oil Alert system (applicable types) will automatically stop the
engine before the oil level falls below the safe limit. However, to
avoid the inconvenience of an unexpected shutdown, always
check the engine oil level before startup.

Oil is a major factor affecting performance and service life.
Use 4-stroke automotive detergent oil.

Drain the used oil when the engine is warm. Warm oil drains
quickly and completely.

Place a suitable container below the engine to catch the used oil,
then remove the oil filler cap, drain bolt and sealing washer.

Allow the used oil to drain completely, then reinstall the drain
bolt and new sealing washer, and tighten the drain bolt securely.

Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw it in the trash, pour it on the ground,
or pour it down a drain.

Reinstall the oil filler cap and oil level dipstick securely.

The Oil Alert system (applicable types) will automatically stop
the engine before the oil level falls below the safe limit.
However, to avoid the inconvenience of an unexpected
shutdown, fill to the upper limit, and check the oil level regularly.

With the engine in a level position, fill with the recommended oil
to the upper limit mark on the oil level dipstick.

Running the engine with a low oil level can cause engine damage.

This type of damage is not covered by the Distributor’s Limited
Warranty.

Running the engine with a low oil level can cause engine

damage. This type of damage is not covered by the Distributor’s

SAE 10W-30 or 5W-30 is recommended for general use. Use a full
synthetic 5W-30 for starting/operating temperatures between 5°F
( 15°C) and

13°F ( 25°C). Other viscosities shown in the chart

may be used when the average temperature in your area is within
the indicated range.
