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 mo-
tors is required for only an instant. The generator 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 electrical 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.
. 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 recommend-
ed 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 .4 to
.5 quarts of oil. Since there is some trapped oil in
the engine, when filling the crankcase the first time
use the dipstick (ref “A”) to ensure that you do not
over fill the crankcase. Reference “B” shows the full
oil level mark on the dipstick.
Oil is added to the engine by removing the oil fill cap
(ref “C”) and adding oil at this point. After filling the
crankcase 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 keep-
ing the crankcase full cannot be overemphasized.
Engine 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 vis-
cosity for the engines. Use the chart to select the best
viscosity for the outdoor temperature range expected.

Oil Recommendations
We recommend the use of Briggs & Stratton Warranty Certified oils for best
performance. Other high-quality detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to
select the best viscosity for the outdoor temperature range expected.

How To Check/Add Oil -
Figure
2
Before adding or checking the oil
x
Place engine level.
x
Clean the oil fill area of any debris.
1. Remove the dipstick (
A
) and wipe with a clean cloth (Figure 2).
2. Fully insert the dipstick.
3. Remove the dipstick and check the oil level. It should be at the top of the full indicator
(
B
) on the dipstick.
4. If low, add oil slowly into the engine oil fill (
C
).
Do not overfill.
After adding oil, wait
one minute and then recheck the oil level.
5. Fully insert the dipstick.
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or
activate a warning device on the equipment. If this occurs, stop the engine and check the
oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches the FULL mark. Start the
engine and check for proper pressure before continuing to operate.
If the oil level is between the ADD and FULL marks,
do not start
the engine. Contact an
Authorized Briggs & Stratton Dealer to have the oil pressure problem corrected.
Fuel Recommendations
Fuel must meet these requirements:
x
Clean, fresh, unleaded gasoline.
x
A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.
x
Gasoline with up to 10% ethanol (gasohol) is acceptable.
CAUTION:
Do not use unapproved gasolines, such as E15 and E85. Do not mix oil in
gasoline or modify the engine to run on alternate fuels. Use of unapproved fuels will
damage the engine components and
void the engine warranty.
To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See
Storage. All fuel is not the same. If starting or performance problems occur, change fuel
providers or change brands. This engine is certified to operate on gasoline. The
emissions control system for this engine is EM (Engine Modifications)
.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 octane/85 AKI (89 RON)
gasoline is acceptable. To remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause decreased performance,
increased fuel consumption, and increased emissions.See an authorized Briggs &
Stratton Dealer for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.
How To Add Fuel -
Figure

WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
x
Turn engine off and let engine cool at least 2 minutes before removing the fuel
cap.
x
Fill fuel tank outdoors or in well-ventilated area.
x
Do not overfill fuel tank. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck.
x
Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
x
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
Replace if necessary
x
If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel cap (
A
, Figure 3).
2. Fill the fuel tank (
B
) with fuel. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck (
C
).
3. Reinstall the fuel cap.
How To Start The Engine -
Figure
4
Rapid retraction of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
WARNING
x
When starting engine, pull the starter cord slowly until resistance is felt and then
pull rapidly to avoid kickback.
