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, check the oil level. This unit has
been shipped with 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 73.6 ounces (2.3 quarts) of oil. Since there is
some trapped in the engine, when filling the crankcase the
first time, use the dipstick to ensure that you do not over
fill the crankcase. The full oil level mark on the dipstick is
depicted in the following image.
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.
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.
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 standard with the Briggs &
Stratton low oil pressure shutdown system. The low oil
shutdown system is designed to prevent severe damage
caused by an insufficient amount of oil in the crankcase.
However, if the unit is repeatedly allowed to shutdown on
low oil pressure, progressive damage will be done to the
engine, shortening the engine’s life. The engine switch will
remain in the “ON” position when the unit is shutdown by
the low oil pressure system.
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 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.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when proper
precautions are not taken.
