3 Setting Up and Basic Adjustment
The KS 1 / KS 3 coffee grinders are suitable for grinding various kinds of coffee. The
grinding fineness can be set from "Turkish fine" to "percolator" with an adjusting knob
provided with a scale. The KS 1 / KS 3 coffee grinders are suitable for use in small food
stores, coffee shops. The simple method of operation enables customers to use the grinder
themselves in self-service stores.
A grinding test run is carried out on each grinder in the manufacturer's factory. This is why
you may find ground material residue in the grinding mechanism!
3.1 Setting-up area
Place the grinder on a level surface free from vibration.
Never operate the grinder in moist, or even worse, in wet surroundings.
3.2 Initial Set-up
Open the top lid. Clear all foreign objects and shipping materials from the hopper
compartment and the entrance to the grind chamber.
3.3 Installation
You have received your grinder in operating condition. Now you only need to connect it to a
power supply system. Proceed as follows:
Determine whether the mains voltage and frequency correspond to the information on
the rating plate.
Protect your grinder with a separate pre-fuse (not included in the scope
of supplies) according to the information provided under Item 2
"Technical data". Make sure that the pre-fuse is not overloaded by other
consuming machines (e.g. fan-forced heaters, deep freezers).
Insert the plug into the available grounded outlet.
3.4 Basic Setting
A grinding test can be conducted when the grinder is ready for
operation.
The basic setting has been set in the factory and the grinding degree is already
set to the finest grind.
For this reason please make no alterations, as this could lead to damage
of the appliance.

4 Operation
Use the KS 1 or KS 3 grinder only in accordance with the instructions listed
under 1.3.
Never place fingers or objects into the grinding gears!
Never exceed the maximum allowable operating time of 40 minutes.
Afterwards, allow the motor to cool off for around 30-40 minutes prior to
switching the grinder on again.
4.1 Operating Controls
Start/Stop Switch
START Pressing the START button initiates grinding only when a bag is in place
behind the spout. The switch will return to this position after a grind cycle has
begun and will remain in this position after grinding has ceased.
STOP pressing the STOP button stops the operation of the grinder.
Grind Selector
Allows the user to vary the grind for each bag of coffee. The grind ranges indicated on the
label allow a very precise grind control. The grinding results may very substantially for
different types and roasts of coffee.

correspond with the fineness set on the scale (marked).
Setting of the scale must only be performed by persons familiar with the unit
after carefully reading the following instructions.
Checking the setting:
When turning the adjusting knob from scale position Turkish to French Press
there must on no account be a sound of metal parts rubbing together.
There must be no sound of grinding discs rubbing together at scale position
Turkish = excessive wear of grinding discs.

Operating instructions
64426 A 03/35 page 11 - 14

5.4.2 Changing the scale setting (adjustment
for customer settings)
The purpose of setting the scale on the rotary knob is to ensure that the fineness
of the ground coffee matches the fineness setting shown on the scale. The
machine is supplied complete with a factory setting and is ready for operation.
Alter the scale setting:
if the fineness of the coffee after grinding does not match the scale and is
therefore not as required.
if a setting for a particular grinding fineness is needed.
IMPORTANT
Only the maintenance staff should be allowed to adjust the scale settings!
Procedure
1. Place a bag under the delivery tube for the
ground coffee.
2. Switch the machine on.
3. Turn the rotary knob (1) in a clockwise
direction as far as the catch point.
4. Use the hexagonal Allen key (approx. 3
turns) to release the studs (2).
5. Turn the centre screw head (3)
- for greater grinding fineness:
clockwise
- for coarser grinding: anti-clockwise.
CAUTION
If you hear a slight sound (grinding discs in contact with each other), this
means that the gap between the grinding discs is too small and must be
increased! (Correct by turning anti-clockwise!)
6. Tighten the studs (2) once more.
Checking the setting:
When turning the adjusting knob from scale position Turkish to French Press
there must on no account be a sound of metal parts rubbing together.
There must be no sound of grinding discs rubbing together at scale position
Turkish = excessive wear of grinding discs. If there is a sound, grinding must
be set more coarsely (see 5.5).
