PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITH 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. The
engine normally holds 78 - 80 oz (2.4 - 2.5 qts) 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.

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

LUBRICATION
Before starting the engine,
fi
ll 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 2.4 to
2.5 quarts of oil. Since there is some trapped oil in
the engine, when
fi
lling the crankcase the
fi
rst time
use the dipstick (ref “A”) to ensure that you do not
over
fi
ll the crankcase. Reference “B” shows the full
oil level mark on the dipstick.
Oil is added to the engine by removing the oil
fi
ll cap
(ref “C”) and adding oil at this point. After
fi
lling the
crankcase to the proper level, be sure you properly
tighten the oil

ing the crankcase full cannot be overemphasized.

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. Winco recommends our 5W-30 fully synthetic
oil to give you excellent protection in cold temperatures
while maintaining excellent performance in warmer
weather.
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 oil level drops below a certain point the low
oil module on the engine will shut it down. This low oil
warning system will automatically stop the engine before
the oil level reaches critical danger point. 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.
FUELING
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when proper
precautions are not taken.
1. Stop engine and keep sparks, heat, and fire away.
2. Handle fuel outdoors only.
3. Wipe up any spills immediately
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 components 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.
