OPM-125/D
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.
DIESEL FUEL
Always use a good grade of # 2 diesel fuel. For cold
weather, blended #1 fuel may be used. Fuel cetane number
should be 45 or higher and the fuel MUST be low sulfur
or ultra low sulfur fuel. See engine operators manual for
additional fuel recommendations including Bio-Diesel fuel.
Never use gasoline or gasohol. Always ensure that the fuel
is clean and free of all impurities. Always be sure to keep the
strainer in place when filling the fuel tank.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
Always check oil level prior to use. 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.
COMPARTMENT INSTALLATION
When installing this generator in vehicle compartments it is
essential that proper care is taken to prevent overheating.
The following guidelines will help prevent these problems.
The easiest way to prevent overheating is to mount the
generator on a slide out tray. This will move the generator
into open air whenever it is in operation. A vertical
opening door can also provide protection from rain during
operation.
If the generator must be installed in an enclosed
compartment during operation it is important to provide
adequate cooling air flow.
This can cause air to recirculate and can result in generator
overheating. The windings will fail prematurely in this
scenario. Separate air intakes for the engine and generator
can help reduce heat. The design should be tested with
measurements taken for engine oil temperature and the
generator stator windings. Contact WINCO for help in
evaluating your application.
LUBRICATION
CAUTION: EQUIPMENT DAMAGE
Failure to maintain the engine oil at the proper level
will result in serious engine damage.
Before starting the engine, verify the crankcase is filled 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 oil in it. The engine normally
holds 1.3 quarts (41.6 oz.) of oil. Use the dipstick to ensure
that you have the proper oil level in the crankcase. The full
