5.Hold the knob in the “TURKISH” (or “1”) position with one hand.

6.Using a large flat blade screwdriver, slowly turn the adjusting screw in the center of the grind selector knob to the right (clockwise) until a metallic whine can be heard due to the rubbing of the grinding burrs.

8.Turn-off the grinder.

9.Push the knob against the dial plate and tighten both set screws on the left side of the grind selector knob.

G2, G3 specifications

The Bunn G3 and G2 models are two of the leading commercial coffee grinders popular among coffee enthusiasts and establishments alike. Both are engineered to provide optimal performance, ensuring that each cup of coffee brewed consistently meets high standards of taste and quality.

The Bunn G3 model is designed to deliver high-speed grinding while maintaining a uniform grind size, thanks to its specialized precision grinding technology. With the ability to grind coffee beans quickly, the G3 can produce up to 3.5 pounds of coffee per hour, making it suitable for high-volume operations. The grinder features a large hopper that holds up to 1.5 pounds of coffee beans, allowing for extended usage without the need for frequent refilling.

One of the standout characteristics of the G3 is its simplicity of use. It comes equipped with a user-friendly interface, making it easy for operators to adjust grind settings according to their brewing methods, whether it be for drip coffee, espresso, or other brewing styles. The grinder also benefits from a low-mess design which helps to minimize coffee grounds spillage during operation.

On the other hand, the Bunn G2 is another exceptional grinder that slightly precedes the G3 in the product line. The G2 also emphasizes efficiency and speed, offering similar grinding capabilities, but features a slightly lower output of up to 2.5 pounds of coffee per hour. Its compact design is ideal for establishments with limited counter space while still delivering excellent performance and consistency.

Both the G2 and G3 incorporate Bunn’s patented Smart Speed technology, which optimizes the grinding speed based on the grind size selected. This ensures that coffee beans are ground uniformly, enhancing extraction and flavor in the final brewed product.

Both grinders are built with durability in mind. Their robust construction and high-quality materials guarantee longevity, even in hectic commercial environments. Additionally, their design allows for easy cleaning and maintenance, which is crucial for maintaining optimal performance over time.

In summary, the Bunn G3 and G2 grinders stand out in the realm of coffee preparation for their impressive features, consistent performance, user-friendly design, and robust construction. These two models cater to both high-volume coffee needs and more compact operational spaces, making them indispensable tools for coffee shops, restaurants, and dedicated coffee aficionados.
