6 qt. pack 5W-30 synthetic oil (engine)

‹RECONFIGURING THE FUEL SYSTEM

NOTE:

All models are configured to run on natural gas from the factory.

To reconfigure the fuel system from NG to LP, follow these steps:

1.Turn the main gas supply off.

2.Remove the carburetor fuel hose from the outlet port of the demand regulator (see Figure 6.2).

3.Disconnect the power wires from the fuel sole- noid located on top of the regulator assembly.

4.Loosen the spring clamp on the small fuel enrich- ment line and remove the hose from the hose barb.

5.Remove the black pipe assembly from the outlet port of the demand regulator.

6.Remove the NG fuel jet (loosen counter clock- wise) from the outlet port.

7.Remove the LP fuel jet (loosen counter clockwise) from the jet keeper port on the side of the regula- tor housing. Install this jet into the outlet port in the regulator casting.

NOTE:

The jet sizes are stamped on the individual jets. The larger jet size is used for running on NG.

8.Install the previously removed NG jet into the jet keeper port on the side of the regulator housing.

9.Install the previously removed black pipe onto the outlet port of the demand regulator.

10.Reverse steps 1-4 in this procedure to reactivate the demand regulator.

2.4L specifications

Generac Power Systems has established itself as a leading provider of energy solutions, and its 2.4L engine is a testimony to their commitment to innovation and reliability. This engine is designed for portable and standby generators, delivering exceptional performance and efficiency.

One of the standout features of the Generac 2.4L engine is its robust design, optimized for both heavy-duty use and demanding applications. The engineering focus ensures that the engine can withstand various environmental conditions while maintaining optimal operation. Additionally, its compact size makes it versatile for various generator models, making it a favored choice among manufacturers and users.

The 2.4L engine incorporates advanced technologies that enhance performance and fuel efficiency. One notable technology is the Electronic Fuel Injection (EFI) system. Unlike traditional carbureted engines, the EFI system provides precise fuel management, improving fuel efficiency and reducing emissions. This means users can expect longer run times on a single tank of fuel, a crucial advantage for those requiring power during outages or remote operation.

Furthermore, the Generac 2.4L engine is equipped with a state-of-the-art cooling system that maintains optimal operating temperatures even under heavy loads. This safeguard helps prevent overheating, thus extending the engine's longevity and reliability. The engine's low oil pressure shutdown feature adds another layer of protection by automatically shutting down the engine if oil pressure drops below a safe threshold.

Noise reduction is another priority for Generac, and the 2.4L engine reflects this commitment. With an integrated muffler and sound suppression features, the engine operates quietly without sacrificing power output. This is particularly beneficial for residential areas or environments where noise may be a concern.

In terms of maintenance, the Generac 2.4L engine requires minimal upkeep. Its design includes easily accessible components, allowing for straightforward maintenance routines. Regular oil changes and filter replacements ensure that the engine continues to perform at its best over time, providing users with peace of mind.

Overall, the Generac Power Systems 2.4L engine combines innovative features, advanced technologies, and reliable performance, making it an attractive choice for those in need of dependable power solutions. Whether for home backup or professional use, this engine exemplifies Generac's dedication to quality and user satisfaction.
