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. This unit
was shipped with most of the oil. The engine normally
holds 57 to 58 ounces (1.78 to 1.81 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 filler 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
The Oil Alert system is designed to prevent damage caused
by insufficient amount of oil in the crankcase. Before
the indicator light comes on, the Oil Alert system will
automatically stop the engine. Note that the ignition switch
will stay in the ON position.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on
low oil level may cause excessive wear which can be
cumulative.
FUEL INJECTION SYSTEM
The fuel injection system has three subsystems: air intake,
engine control, and fuel control. The ECU uses various
sensors to determine how much air is going into the
engine. It then controls how much fuel to inject under all
operating conditions.
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.
