Annual Maintenance (cont.)

4.Remove dasher assembly, inspect stator bearings and replace shaft seal set. (See Care and Cleaning).

5.Remove rear panel and inspect "V" belt.

6.Inspect the drive shaft square hole for wear (rounding-out).

7.Check drive shaft and motor shaft bearings for excessive wear.

8.Reinstall side and back panels.

9.Re-connect power supply.

Belt Adjustment

CAUTION: Unplug the machine before performing any adjustments. This proceedure must be

!done by a qualified technician.

Check the belt tension. The proper belt deflection is 1/2" over all. If the deflection is more than 1/2" the motor will need to be lowered. If the deflection is less than 1/2" the motor will need to be raised. Follow this procedure to adjust the motor to achieve proper belt tension.

1)Unplug the machine and remove both side and the rear panels.

2)Locate the motor flange bearings (#W038.0009). These are the pillow block bearings that hold the motor to the cra- dle. The motor is double shafted and the shaft extends through a bearing on each end. The bearing is held to the motorcradle by two allen bolts on each bearing.

3)Loosen the allen bolts on each bearing. Do not loosen the setscrews that hold the bearing collar to the motor shaft.

4)Lower the motor or raise the motor as needed. The motor must be kept level from front to back. Do not lower or raise only one end of the motor. This will result in excessive belt wear and belt noise.

5)Tighten all four allen bolts down. Align the motor pulley with the top pulley if needed.

6)The motor pulley should be in alignment with the large (driven) top pulley. Use a straight edge along the top pulley.

7)If the pulleys are not in alignment, remove the setscrew from the motor pulley and move either in or out as needed.

8)Reinstall the setscrew. Use non-permanent loc-tite on the setscrew and tighten it back down on the motor shaft. Please be sure the setscrew is tightened down flat on the motor shaft.

9)Return the unit back to service.

At the heart of each model is a set of high-quality, stainless-steel burrs designed for consistent grind size. Burr grinders, as opposed to blade grinders, provide uniformity in particle size, which is essential for optimal extraction and flavor in coffee brewing. The Grindmaster series employs advanced grinding technology that minimizes heat transfer, preserving the delicate oils and aroma of the coffee beans during the grinding process.

One of the main features across these models is their user-friendly interface. They are equipped with intuitive controls, allowing users to easily adjust grind settings to achieve the desired coarseness or fineness. The 5711, for instance, is celebrated for its precision adjustment system, enabling users to fine-tune their grind settings for varying brewing methods, from espresso to French press.

Another noteworthy characteristic is the incorporation of an efficient motor that not only ensures smooth operation but also enhances durability for long-term use. These grinders operate quietly, making them suitable for environments where noise reduction is essential, such as coffee shops or homes with open layouts.

Safety and convenience features are also integral to the Grindmaster series. Most models include a safety lock to prevent operation while the grinder is being cleaned or adjusted. The removable grinding chamber makes it simple to clean and maintain the equipment, extending its lifespan and ensuring consistent quality.

The design of the Grindmaster grinders reflects both functionality and aesthetics. Their sleek and modern appearance fits seamlessly in both commercial settings and home kitchens. The robust construction withstands daily wear and tear, making them a reliable choice for frequent use.

In summary, the Grindmaster 5711, 5941, 5311, and 5511 models are distinguished by their advanced grinding technology, user-friendly design, durability, and aesthetic appeal. These grinders not only enhance the coffee brewing experience but also exemplify the commitment to quality that Grindmaster is known for in the specialty coffee industry.
