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 engine-generator set be sure to remove all the
information sheets and manuals from the carton.
1. As you receive your unit, it is critical to check it for any damage. If
any damage is noted, it is always easiest to refuse the shipment and
let WINCO take care of the freight claim. If you sign for the unit, the
transfer of the ownership requires that you file the freight claim
2. Before proceeding with the preparations of your new generator
for operation, take a couple of minutes to ensure the unit you have
received is the correct model and review the specification pages in this
manual to ensure 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 recommended grade 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 1.4 to 1.5 quarts of oil. Since there is some
trapped in the engine, when filling the crankcase the first time, use
the dipstick (‘A’ in following image) to ensure that you do not over fill
the crankcase. The full oil level mark on the dipstick is depicted in the
following image as ‘B’.
Oil is added to the engine by removing the oil cap and adding oil at
this point. After filling the crankcase to the proper level, be sure you
properly tighten the oil fill cap (‘C’).
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. Engine failures resulting from inadequate
or improper lubricant are considered abuse and not covered by the
generator or engine manufacturer’s warranty.

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 dif
fi
culty is experienced in
starting motors, turn all other electrical loads off and if
possible reduce the load on the electric motor.

temperature range expected.
OIL ALERT SYSTEM
This generator is equipped with a low oil shutdown system. This Briggs
& Stratton engine uses an oil pressure switch system. If the system
senses low oil pressure, it will automatically shut down the engine. This
feature is designed to prevent costly repairs and downtime.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on low oil level may cause
excessive wear which can be cumulative.
GASOLINE
When using gasoline, always use fresh, clean, unleaded fuel. The
engine is certified to operate on unleaded gasoline with a minimum
octane rating of 87 or higher. Gasoline containing no more the 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasolines, such as E15 or E85. Do not mix
oil in the gasoline. Use of unapproved fuels will damage the engine
compenents and void the engine warranty.
Use of fuels with content of ethanol greater than shown above may
cause starting and/or performance problems. Always ensure that the
fuel is clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when proper precautions
are not taken.
Never use gasoline that has been stored for an extended period of
time as the fuel will lose its volatile properties and you will be left with
varnish residue. The varnish like substance will clog the carburetor and
will not burn properly.
The use of fuel additives, such as Sta-Bil, or an equivalent will minimize
the formation of fuel gum deposits. If a unit has been out of operation
for an extended period of time, it is best to drain old fuel from the
engine and replace with fresh fuel before attempting to start.
