9) WARNINGS REGARDING OPERATION
•
OPERATING RANGE OF THE MOTOR
IN THE VERSIONS WITH SINGLE-PHASE MOTORS, OBSERVE THE DUTY CYCLE
ON / OFF STATED IN THE LABEL LOCATED ON THE LEFT SIDE OF THE APPLI-
ANCE.
E.g.: a data on the label 20s ON / 30s OFF point out an allowed duty cicle of 20 sec-
onds switched on and 30 seconds switched off.
•
FIRST INSTALLATION
For the correct use of the grinding blades, at the first installation or whenever
the grinding blades have been replaced, grind some doses of coffee. Do not use
those first doses.
For the appliance to function at its best, on its first installation and every
time the hopper is cleaned, after having ground a few coffee doses, clean the
inner surface of the funnel (dosing unit) with a dry brush.
10) SAFETY DEVICES
•
THERMAL OVERLOAD PROTECTION
The appliance’s motor is protected against overheating resulting from overcurrents
by a thermal overload protection which, when tripped, cuts off the power supply
to the motor. Should the protection trip as a result of anomalous operation, such
as the grinding blades jamming, the appliance must be turned off using the on-off
switch, UNPLUGGED FROM THE MAINS, AND SKILLED TECHNICAL PER-
SONNEL CONTACTED. NEVER PERFORM ANY WORK ON THE APPLIANCE
WHILE IT IS ATTACHED TO THE MAINS, TO AVOID THE RISK THAT MOTOR
TURNS ON SUDDENLY.
If the appliance overheats as a result of the motor stopping, allow the appliance
to cool down before performing any repair work.
•
MOTOR LOCKING MICROSWITCH
(MAJOR, KONY, ROBUR, ROYAL, STARK)
The system that protects
against accidental contact
with the rotating parts of
the grinding system con-
sists of a microswitch, situ-
ated under the body of
the appliance, that cuts the
electricity to the motor.
