NEVER OPERATE THE GRINDER IF THE BEAN HOPPER IS NOT FULLY SECURED IN ITS POSITION.
Before plugging in the electrical cord, make sure:
o The appliance voltage and frequency rating (according to the back side label) is the same as the
supply mains.
o The wall socket is fitted with an efficient ground contact. DONOT plug the appliance into the supply
mains if the ground system was not positively checked to be in compliance with current safety rules.
IT IS COMPULSORY TO GROUND THE APPLIANCE. The manufacturer can not be held responsible in
the event that this regulation is not complied with.
o The power consumption of the appliance (according to the backside label) is consistent with the
relevant wall socket capacity.
o The wall socket is protected against short outs and power surges.
o Do not use extension cables, plug adapters for multiple sockets, or make shift connections.
Plug in the appliance.
Upon first time operation, and before placing beans into the hopper, VISUALLY check that the blade rotation
direction is clockwise by switching the appliance ON for a short while.
Should the rotation direction be wrong, do not use the appliance and contact your local dealer for further
instructions.

Modes of operation:
The CF-350v1 can be operated in 3 different modes:
• Continues mode, the grinder will grind continuously into the filter handle or any collecting tool as
long as the demand switch (fig 5.2) is pressed.
• Single cup mode, while demand switch (fig 5.2) is pressed the grinder will grind a precisely timed
dose (time can be programmed by user) into the filter handle.
• Double cup mode, while demand switch (fig 5.2) is pressed the grinder will grind a precisely
timed dose (time can be programmed by user) into the filter handle.
Activating (or deactivating) each one of the modes, is achieved by single pressing of the relative mode
selector button. Once activated, a green LED will turn to ON state on each one of the selectors.

Dose counting LCD:
• The CF-350v1 model is equipped with 3 independent dosing counters.
• In order to view each one of the counters a single press on the counter selector will flip the LCD to
the next counter and the relative counter’s LED will turn on.
• 2 of the counters are resettable; in order to reset each of these 2 counters a 5 sec continues press
on the counter selector will zero the relative counter.
• On single cup mode each coffee demand will increase the counting on all the 3 counters in 1.
• On double cup mode each coffee demand will increase the counting on all 3 counters in 2.
• On continues mode the counters are not counting.
Programming grinding time for single and double cup mode:
The CF-350 is factory set with time values for single and double dose grinding periods. These pre set
values are obviously estimated and user should find his own times according the coffee grinding request. In
general as the coarseness of grind is finnier the time required to grind same amount is longer. Additionally
different type of coffee blends and coffee shops are requiring different amount of coffee powder for their
single and double cup (6.5gr to 9.5gr per single cup and 11gr to 18gr for double cup). The CF-350 is
supporting the needs of the user to change grinding time setting occasionally.
In order to change time setting of single cup or double cup mode please follow these steps:
1. Press the desired mode selector button continuously for longer than 5 sec. when in program mode
the mode selector’s LED is blinking.
2. Watch the LCD display is now showing your current set up time (in seconds and tents of seconds).
3. In order to increase or decrease set up time simply rotate the peripheral scale of the knob and watch
the time set up on the LCD is changing up or down according direction of rotation.
4. When reaching the desired time value press shortly the mode selector button to return to normal
working mode (watch the display is returning to counter mode)

Grinding in continues mode:
The CF-350v1 is designed to grind continuously (as long as the demand switch is pressed) into filter
holder or any other collecting tool (not included).
1. Select continues mode button.
2. Place the filter handle between holder legs and press the demand button as desired.
3. If you wish to grind into a collecting tool, unscrew the fork legs (fig 5.3) and place the collecting tool
pressing the demand button (fig 5.4).

Operating intervals:
• On continues mode the manufacturer is not recommending using the appliance continuously for a period of
time exceeding 4 minutes (grinding of approx 0.5 kg).
• It is a normal occurrence that during long grinding periods the grinding chamber will heat up. In order to
achieve best grinding results, it is recommended to grind coffee in short intervals of a few minutes each.
Adjusting coffee grind
• The grinding blades’ distance was factory pre adjusted to satisfy different common coffee grinds (from super
fine to coarse) corresponding gap distance from 0.05mm to 0.5mm.
• Turning the grinding dial incrementally counterclockwise will make the grind finer and turning it clockwise will
make the grind coarser.
• Grind a small amount of coffee and test its coarseness with your espresso machine.
• As coffee beans’ qualities and characteristics are changing from time to time it is recommended repeating this
adjustment once in a while.

6) SAFETY DEVICES
A) Thermal overload protection
c
t
j
c
.
ww
In order to eliminate the risk of fire the motor is equipped with an overheat protection device which will cutoff the
motor’s power supply should it reach a high temperature.
• In the event that the thermal protection is tripped as a result of malfunction (e.g.: jammed blades, worn out
bearings, foreign object in grinding chamber, etc.) the appliance main switch should be turned off immediately
and the main power plug must be disconnected. For further handling of the device contact your local service
provider, and allow the appliance to cool down before any further maintenance.
• In the event that the thermal protection is tripped as a result of a long continuous operation (read section 5,
for operating intervals) allow the appliance to cool down and reset the thermal cutoff protection by
unplugging the main cable from the socket. On the first operation after resetting a tripped overheat
protection device observe the grinding quality and noise level, and if there are any irregularities shut down the
appliance and call a certified technician for a complete analysis of the appliance.
w
B) Grinding chamber safety screws
The grinding chamber can be a hazardous area if the proper precautions aren’t observed. The hopper safety screw
(fig4.1) and the grinding dial safety screw (fig6.1) should never be removed during normal operation of the
appliance unless the appliance is disconnected from the power source.
7) SAFETY INSTRUCTIONS
•

8) MAINTENANCE AND SERVICE
Warning: All appliances’ technical handling operations, such as installation, maintenance, or service
should be performed by certified personnel or by your local dealer.
Check the state of the grinding blades periodically (approximately every 50kg of grinded coffee) Good condition
blades will result in a high quality grind and prevent the appliances over heating. Replace grinding blades every
400KG of grinded coffee (when using original replacement parts)
Be aware of the appliance’s noise level. In case the noise level is higher than normal or irregular noises are coming
from within the appliance, get certified personnel to perform an overall check of the appliance.

Take off the bean hopper (by releasing Bean Hopper safety screw, Fig.4-1) and rinse it thoroughly with water and
soap. As the bean hopper is made of clear polymer, use only liquid detergent (free of abrasive components) and
soft sponge. Before reinstalling the beans hopper back to its position, make sure it is dried thoroughly. To ensure
great coffee taste, clean the bean hopper periodically.
Cleaning the grinding chamber grinding parts and powder outlet housing
