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 Honda engine uses a float switch mounted inside the
engine. 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 a 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.
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.
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.
PREPARING THE UNIT
UNPACKING
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
CAUTION: EQUIPMENT DAMAGE
Failure to maintain the engine oil at the proper level
will result in serious engine damage.
This unit has been shipped with oil. Always check the
crankcase for proper oil level before starting the engine. 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 38.4 ounces (1.2
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.
