Giesen W6A Coffee Roaster - Version 1.0 35
11.4 Adjusting the drum
Adjusting the front bearing might be necessary when;
• A scraping sound is being heard - the distance needs to be bigger.
• When beans are falling through - the distance needs to be smaller.
Only authorized skilled persons are allowed to adjust the drum. Always do this on
the instruction of a Giesen Coffee Roasters trained person.
1. Unscrew the three countersunk screws with the supplied tools.
2. Turn 90° clockwise with the key hook to adjust the drum back.
3. Use the key hook to turn the drum anticlockwise until you hear the drum lightly
scraping the front plate. When you hear this sound, you need to stop. Then, turn
the key 45° clockwise. Your drum is now adjusted.
4. To lock the drum adjustment, tightly screw in the three countersunk screws you
removed earlier.
