DS-68 - Operating manual
Introduction:
It might seem simple to make a coffee, but if you look a little bit closer, in order to
prepare a good cup of coffee, precise rules have to be followed. The formula to
get a perfect cup of expresso depends largely on the quality of the coffee grinding
machine. In order to achieve an indisputable quality and a breathtaking taste it is
mandatory to follow three rules:
1. A precise mixture
2. The correct use of equipment.
3. A thoroughly trained person.
To enjoy a good cup of coffee, unlike what you believe, it is not enough just to
choose a particular coffee mixture. A skilled operator, who follows the proper
preparation procedures and uses the machinery in an appropriated manner,
contributes decisively at the creation of a masterpiece.
This is why professionals give so
much importance to their espresso
and grinding machines. Being
familiar with their machines,
keeping them in perfect working
conditions and using them to the
best of their ability, are the skills
that belong to a true coffee master.
The quality of a good espresso
coffee is the result of a series
of operations, grinding having
an important role. The grinder,
therefore, is for the operator
one of the most important tools,
whose structure must meet certain
characteristics such as: strength,
durability and functionality.

Operating instructions:
Preliminary operations
Check that the hopper is positioned correctly on the appliance. Close the Hopper
locking slide (fig. 1) and fill the hopper with coffee beans. Open the slide to allow
the coffee beans to fall in the grinding chamber.
Adjusting the grind
Your new DS-68 serie is delivered from the factory at a preset grinding of minimum
fineness.
Use the Adjustment disk located under the hopper (fig. 1), for obtaining a finer or
coarser grinding result.
The Adjustment disk is functional only when the Indexing mechanism (fig. 1)
is hold down.
For coarser grinding turn the Adjustment disk anti-clockwise, for finer grinding turn
the disk clockwise.
The Adjustment disk is blocked at the chosen position by releasing the Indexing
mechanism.
Grind small amounts of coffee in order to determine the optimal degree of fineness.
A simple method to verify the grinding setting, is at the espresso machine. If the
coffee comes out of the espresso coffee machine very quickly, it means that the
coffee is grounded to coarse. If it comes out too slowly, it means that the coffee is
grounded to fine.

Safety protection:
THERMAL OVERLOAD PROTECTION
The appliance’s motor is protected against overheating by a thermal protection
which, when tripped, cuts off the motor’s power supply. If the protection trips as a
result of anomalous operation, such as jamming the grinding blades, the appliance
must be turned off using the ON/OFF switch (fig.1), DISCONNECTED FROM THE
MAINS, AND CONTACT A LICENSED TECHNICIAN.
Noise level:
The maximum noise emission of this coffee grinder is measured in UNI EN ISO 3741
reverberating chamber in compliance with the EN 60704-1 regulations and complies
with the EN 60704-1:1998 and EN 607043:1996 regulations.
The daily noise exposure of a worker, due only to an appliance’s limited operation of
240 minutes per 8 hours, is 78 dB (A), according to ED 89/188/ECC and ED 200311/
EEC. Therefore, during the daily operation, measures must be taken in order to
prevent any injury from noise exposure (article 3-8 of ED 2003/10/EEC).
Maintenance:
It is essential to check the status of the cable and plug periodically.
IN THE EVENT OF DAMAGED SUPPLY CABLE OR PLUG, CALL IN A LICENSED
TECHNICIAN TO REPLACE THEM. THIS WILL PREVENT ANY FUTURE DAMAGE OF THE
APPLIANCE.
It is recommended to use original replacement parts to assure the proper
working conditions of the appliance. A licensed technician must perform periodic
maintenance, including detailed inspection of those components subject to wear.
The status of the grinding blades must be checked periodically. Keeping them in an
excellent condition, assures better productivity and cooler coffee outcome.
Cleaning the appliance:
THE APPLIANCE CANNOT BE CLEANED USING WATER JETS.
THOROUGH CLEANING MUST BE PERFORMED PERIODICALLY BY A LICENSED
TECHNICIAN.
Use perfectly clean, disinfected cloths or brushes for cleaning.
Do not use abrasive products for cleaning in order to prevent damaging the shiny
parts.
