Before commissioning

Operating principle of Buddy
The shot sizes, i.e. the grind quantities per shot, are defined by the grinding time in the Buddy grinder model. The user can either use one of the two recipes (Single Shot / Double Shot) for the grinding process or he or she can control the grinding time manually (Manual Grinding).
The grinding process starts automatically when the portafilter is inserted and stops automatically after the defined grinding time has elapsed (grinding according to recipe) or when the portafilter is removed (Manual Grinding). The automatic grinding process is triggered by the inserted portafilter actuating the trigger switch (6).
The following recipes (grinding times) are preset at the factory:

• Single Shot (Symbol ): 3.5 seconds (approx. 7–8 g)
  Double Shot (Symbol ): 6.5 seconds (approx. 14–16 g)

To define other grinding times for the recipes, proceed as described in chapter „Setting or changing the recipe/grinding time“.

Operating principle of Buddy Doser
The grinding process is controlled directly via the On/Off switch (4) in the Buddy Doser grinder model: The grinding process starts when you turn the On/Off switch to the ON position and stops when you turn the On/Off switch to the OFF position. The ground beans drop out of the grinding mechanism directly into the dispensing chamber (19). The operator dispenses the ground beans collected in the dispensing chamber into the inserted portafilter.

Check the grinder and scope of delivery

1. Remove the grinder from the packaging.
2. Check that the delivery is complete.
3. Check for damage to the grinder or the individual parts. If this is the case, do not use the grinder. Contact your dealer (see chapter „Maintenance and service“).
4. Check that the direction of rotation of the grinding mechanism is correct before using it for the first time (see chapter „Check before initial operation“).

Setting up and connecting the grinder

1. Place the grinder on a level, stable and vibration-free surface.
2. Make sure the grinder is switched off (On/Off switch (4) in the OFF position) and connect the grinder to the mains by inserting the power plug (5) in a properly installed earthed socket.
3. Insert the drip tray (8) in the corresponding housing recess.

Inserting the bean hopper

1. Place the bean hopper (1) on the grinder. When fitting the bean hopper, ensure that the hole for tightening the securing screw of the bean hopper is positioned in front of the securing screw (14) on the left-hand side of the bean container intake (3).
2. Press the bean hopper down slightly into the bean hopper intake.
3. Tighten the securing screw for the bean hopper clockwise.
   IMPORTANT: Never use the grinder without securely fixing the bean hopper by tightening the securing screw.

Check before initial operation

• Prior to the initial use, check that the direction of rotation of the grinding mechanism is correct before putting beans in the bean hopper (1). Switch the grinding mechanism on for a few seconds and make sure that the grinding disc rotates in a clockwise direction.

Adjusting the portafilter support (only for Buddy)
Adjust the portafilter support (8) to the size of the portafilter of your espresso machine as described below.

1. Make sure that the grinder is switched off (On/Off switch (4) in position OFF).
2. Unscrew the two screws (10) for adjusting the portafilter support (left and right) a few turns anticlockwise. The portafilter support (8) is lowered as far as it will go.
3. Insert the portafilter in the portafilter intake (9).
4. Push the portafilter support upwards until the portafilter fits exactly between the portafilter support and the portafilter intake. If the supplied portafilter support does not fit, contact your dealer (see chapter „Maintenance and service“).
5. Hold the portafilter support in position and retighten the two screws for adjusting the portafilter support (left and right) clockwise.

Operation

NOTE!-Danger of overheating!
Exceeding the maximum permissible grinding quantity per day can lead to overheating of the grinder.

• Do not exceed the maximum grinding quantity per day (see chapter “Technical data”).

The grinder has a thermal cut-out which interrupts the grinder’s circuit in the event of a thermal overload. To restart the grinder, set the On/ Off switch (4) to the OFF position and remove the power plug from the socket to disconnect the power supply. Allow the grinder to cool down for 30 minutes. Afterwards, you can restart the grinder as normal by inserting the power plug in the socket and setting the On/Off switch to position I (see chapter „Troubleshooting“).

NOTE!- Risk of damage!
The operator does not influence the thermal cut-out. If the cut-out has tripped several times, a service partner must be contacted for advice, as the motor winding could be damaged.

Filling with espresso beans

1. Remove the lid from the bean hopper (1).
2. Fill the bean hopper with whole roasted espresso beans from above. The maximum filling quantity should be approx. 1 cm below the edge of the bean hopper.
3. Replace the lid on the bean hopper.
4. Open up the bean hopper to the grinding mechanism by pulling out the sliding valve (2).

Changing the espresso bean type

1. Close the bean hopper (1) to the grinding mechanism by pushing in the sliding valve (2).
2. Use the Manual Grinding function to grind the espresso beans remaining in the grinder until the grinder idles.
3. Undo the securing screw (14) for the bean hopper.
4. Remove the bean hopper from the grinder by lifting it upwards.
5. Remove the remaining espresso beans from the bean hopper.
6. Remove any excess beans from the bean hopper intake.
7. Replace the bean hopper and fix it with the securing screw (14) (see chapter „Inserting the bean hopper“).
8. Pour the new espresso beans into the bean hopper.
9. Open the bean hopper by pulling out the hopper slide.
10. Grind 2–3 shots to remove any residue of the old espresso beans, to warm up the machine, and to avoid any fluctuations in the dosage.

Setting the grinding degree
You can use the grinding degree adjustment (13) for the stepless adjustment of the desired grinding degree. Read the preset value on the grinding degree scale, which is located on the grinding degree adjustment.

• Turn the grinding degree adjustment anti-clockwise to reduce the grinding degree (= finer grind).
• Turn the grinding degree adjustment clockwise to increase the grinding degree (= coarser grind).
• Decrease the grinding degree only when the grinder is in operation.
• To avoid/eliminate imbalances when adjusting the grind, we recommend that you first set a coarser grind and only then adjust the grinding degree adjustment down from there to the desired finer grind.
