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.
