PRO4000 specifications

The Briggs & Stratton PRO4000 is a dependable and powerful generator designed to meet the needs of both residential and professional users. With a robust build and advanced technology, it offers an excellent solution for powering essential appliances during outages or for use at worksites.

One of the standout features of the PRO4000 is its impressive peak power output of 4000 watts, providing ample energy for multiple devices. This makes it an ideal choice for running refrigerators, sump pumps, or power tools simultaneously. The generator's continuous running wattage capacity ensures a steady power supply, allowing users to maintain their usual lifestyle even in emergencies.

The PRO4000 is equipped with a reliable Briggs & Stratton engine, renowned in the industry for its durability and efficiency. The engine employs OHV (Overhead Valve) technology, which enhances performance and fuel efficiency while reducing emissions. This means users can operate the generator longer on a single tank of fuel, making it economical and environmentally friendly.

Portability is another significant feature of the PRO4000. It is designed with a compact frame and comes with heavy-duty wheels and a foldable handle. This allows for easy transportation across various terrains, making it suitable for camping trips, construction sites, or any outdoor activities where temporary power is required.

Safety is a priority with the PRO4000. It integrates advanced safety features like overload protection that automatically shuts off the generator to prevent damage, ensuring it runs smoothly and safely. The generator also incorporates a low oil shutdown feature that protects the engine from damage by shutting down when oil levels are too low.

User-friendly controls make the PRO4000 accessible for anyone to operate. The generator features clearly marked outlets for easy connection of devices, and an easy-to-read fuel gauge allows users to monitor fuel levels without opening the tank.

In summary, the Briggs & Stratton PRO4000 stands out with its powerful performance, reliable engine technology, portability, and safety features. Whether for home use during power outages or for commercial applications, the PRO4000 offers the versatility and reliability that users can depend on. It is an investment that ensures peace of mind and preparedness for whatever challenges come your way.
