DCX3000 3.0kW, 36/48VDC Portable Generator Quick Guide

The following instructions are intended to supplement the DCX3000 Operator’s Manual. Read and adhere to all safety
instructions listed in the Operator’s Manual (Alpha P/N 041-028-B0) and this document. If you have any questions
regarding safe operation of the generator, consult the Operator’s Manual or contact Alpha Technical Support.

WARNING!

Do not make or break any connections between the power supply battery pack and generator while the
generator is running. Turn the generator off before disconnecting any cables or equipment.

CAUTION!

Always check the engine oil level prior to operating the generator. Failure to do so could lead to
irreparable damage to the engine.

CAUTION!

Only use 86 octane fuel or higher and no more than 10% Ethanol or 5% Methanol by volume.

1.0 Connecting Generator

1. Open the maintenance cover (see Figure 1-1).

2. Using the DC voltage selector switch, select either 36V or 48V (see Figure 1-1).

4.0 Engine Oil Recommendations

Oil affects performance and service life for the engine. Always use 4-stroke automotive detergent oil. The engine
can hold .58 U.S. qt (.55 L) of oil.

SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average
temperature in your area is with the recommended range (see Figure 4-1).

AMBIENT TEMPERATURE

Figure 4-1, Oil recommendations for ambient temperature.

The SAE oil viscosity and service category are in the API label on the oil container. We recommend that you use
API SERVICE category SJ or later (or equivalent) oil.

5.0 Changing Engine Oil

CAUTION!

Hot engine oil can BURN. The engine should be warm to the touch but not hot when changing the oil.
Draining warm oil assists rapid and complete draining.

1. Open and remove the oil maintenance cover (see Figure 5-1).

2. Place a suitable container below the engine to catch the used oil, then remove the oil ller cap/dipstick. Using
a 10mm wrench remove the drain plug and sealing washer (see Figure 5-1).

3. Allow the used oil to drain completely, then reinstall the drain plug and sealing washer. Tighten the plug
securely.

Note: Improper disposal of engine oil can be harmful to the environment and may violate local and federal
laws. Dispose of the used oil in accordance with all local, state and federal laws.

4. With the generator in a level position, ll to the outer edge of the oil lter hole with the recommended oil (see
Figure 5-2).

5. Screw in the oil ller cap/dipstick securely.

6. Reinstall, close, and latch the oil maintenance cover.

Note: Always wash your hands after handling motor oil.

6.0 Draining Fuel Tank and Carburetor

WARNING!

Gasoline is highly ammable and explosive. You can be burned or otherwise seriously

injured improperly handling fuel. STOP the engine and let it fully cool before adding or
draining fuel. Remove all sources of ignition, heat, and spark from the immediate area.
Wipe up spills immediately.

1. Open the maintenance cover.

2. Place a suitable gasoline conatiner below the carburetor
drain hose.

3. Loosen the carburetor drain screw and drain the gasoline
from the carburetor (see Figure 6-1).

4. After all the fuel has drained into the container, tighten the
drain screw securely.

5. Place an approved gasoline container below the sediment
cup, and use a funnel to avoid spilling fuel (see Figure 6-2).

Note: The engine fuel tank can hold 3.5 U.S. gallons
(13.3L) of fuel.

6. Remove the sediment cup, then move the Fuel Valve Lever
to the ON position.

7.0 Storing Generator

Proper storage preparation will help prevent corrosion damage and help extend the life of the fuel system. Prior to
storage clean the generator entirely with a damp rag. Once dry, touch up damaged paint and lightly coat exposed
metal surfaces with a quality rust inhibitor. To prevent fuel oxidizing, entirely drain the fuel system. If this is not

possible, ll the fuel tank entirely to reduce the air in the tank (air hastens fuel oxidation) and ensure a quality

gasoline stabilizer is used per the manufacturer's recommendations. It is also good practice to change the oil before
long term storage.
