Introduction:
Since immemorial time, making coffee has been an art. Precise rules have to be followed
in order to succeed. The formula to get a perfect cup of express coffee 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 grinder
machines. Being familiar with his 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 tool,
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 and secured to the Coffee
grinding Adjustment disk with the relevant screw (fig.1). 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 DKS-65 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, to 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. ADJUSTING GRINDING
