5. SET-UP AND BASIC ADJUSTMENT

A grinding test run is carried out on each grinder in our factory.

This is why you may ﬁnd ground material residue in the grinding

mechanism!

You have received your grinder in operating condition. Now you

only need to mount the hopper and connect the grinder to the

mains plug. Proceed as follows.

5.1 Usage Location

Place the grinder on a level, vibration-free surface.

Never operate the grinder in moist, or even

worse, in wet surroundings!

5.2 Mounting the hopper

• Position the hopper, item 1, in the bayonet in the grinder´s lid.

Note: The hole in the hopper-adapter has to line up with the

lock screw, item 2, in the lid.

• To lock the hopper grab the hopper with both hands and turn it

clock-wise until it clicks in.

• Secure the hopper with the lock screw, item 2, by using a allen

wrench 2mm or in case of 100-120V-model use a screwdriver

• Open the hopper slider, item 16, in the adapter.

4. SAFETY DEVICES OF THE GRINDER

Thermal overload circuit breaker

The motor of the grinder is protected by a thermal overload circuit

breaker, which interrupts the motor´s electric circuit in the event

of electric overload. The trip switch, item 18, must be pressed to

enable the grinder to be restarted.

The user has no inﬂuence whatsoever on these

circuit breakers. If the circuit breaker trips re-

peatedly, an authorised service partner must be

consulted, as the motor´s winding may be dam-

aged.

Motor protector

The winding of the motor is protected by a thermal switch (ther-

mo pill / bimetall), which will trip when the motor heats up sig-

niﬁcantly. The grinder cannot be started again. Let it rest for appr.

30 minutes. The thermal switch will reconnect the motor auto-

matically.
