Using the Slicer
Ensure the slicer is turned off and that the thickness selection knob is set to “0”.
Ensure that only one LED is lit on both the STROKE button and the SPEED button.
Manual Use
1. Turn the function mode selector knob anti-clockwise to Manual.
2. Pull back the carriage completely (towards the operator) to the loading position.
3. Lift the end device up, into the rest position.
4. Place product onto the table, the product will press against the fence plate because of its weight. Block it
with the end device by lowering it onto the product and pressing down slightly.
5. Rotate the thickness selection knob anti-clockwise to the desired setting.
6. Turn the slicer on by pushing the start button. The power indicator light, which is located above the switch,
will illuminate.
DO NOT hold the food product with your hand. Never put your hand on or around the table while the slicer
is on. The end device handle is the only part of the slicer you should touch while slicing.
7. Grip the handle attached to the meat table support and manually push the carriage back and forth. This
handle and the end device handle are the only part of the slicer you should touch while slicing. DO NOT
catch slices with your hands, let slices drop onto the receiving area.
If a product needs to be adjusted during slicing, first turn the slicer off and then pull the table all the way
towards you.
8. When the weight or size of the product does not allow a proper slice, use the end device handle and apply
some pressure to the product.
9. After the last slice stroke, pull the carriage all the way towards you. Turn the slicer off by pressing the stop
button, the power indicator light will go out. Turn the thickness selection knob clockwise until it stops to close
the slicer table.
10. You can now unload the product from the table.

7
Automatic Use
1. Turn the function mode selector clockwise to the Automatic position.
2. Pull back the carriage completely (towards the operator) to the loading position.
3. Lift the end device up, into the rest position.
4. Place product onto the table, the product will press against the fence plate because of its weight. Block it
with the end device by lowering it onto the product and pressing down slightly.
5. Regulate the thickness of the slice required and then start the machine by pressing the ON button. In this
way the blade and food plate carriage start together.
6. When you start the carriage movement there will only be one LED on indicating low SPEED, and you can
increase the speed by pressing the SPEED button once or twice.
7. When you start the carriage movement there is only one LED on the STROKE light indicating short carriage
run and if you want to increase the carriage run press the STROKE button once or twice.
Note: When you push the OFF button, you stop the blade and the carriage movement. But the slicer keeps the
speed and stroke settings, so when you push the ON button the slicer restarts with the same carriage run and
speed that it was using before it was stopped.
If you want to stop the carriage movement, you can turn the function mode selector knob anti-clockwise or you
can press the SPEED button so that none of the LEDs are illuminated.
You can return to automatic mode with the previous speed and stroke settings by turning the function mode
selector knob again.
Note: You will only lose your settings by unplugging the unit.
Warning: The circuit board has a thermal protector. If the circuit board reaches 80°C (which could happen if you
use the slicer continuously for 4 hours without turning it off), the slicer turns off. So, you must unplug the power
cable and not use it for 5 minutes to allow it to cool down. After 5 minutes, you can start to use the machine again.
Slice Counter (if present)
The slice counter counts from 0 to 999.
When the count is exhausted the carriage stops
automatically.
You can set total cuts in single units, tens and hundreds.
The amount required needs to be entered one digit at a
time from right to left, i.e. starting with the units, then tens,
and finally hundreds. The display is red LED. During the
count, the indicator lights up.
Click the SET button, the unit display flashes. Click the
button on the left of the reset button to reach the desired number. Click SET.
Repeat the operation for setting the 2nd and 3rd digits.
When the display no longer flashes, click the RESET button. The slice counter is now set for the desired number of
slices.

Cleaning Instructions
Daily cleaning should be considered mandatory for all equipment used in the preparation of food. When using a
meat slicer and with the possibility of cross contamination, these units should be cleaned before slicing each new
product. Once your slicer makes contact with any food product, the entire slicer, including removable parts, must
be thoroughly cleaned. This process is to be repeated at the end of each working day. If the machine has not been
used for a while it must be cleaned before use.

Sharpening the Knife
When and How Often to Sharpen the Knife
•Symptoms of a dull knife are excess waste on the unsliced portion.
•The blade needs to be sharpened periodically to provide consistent slices and maximum food product.

•WARNING: The blade can be sharpened up until the distance between
the cutting edge of the blade and the inside border of the blade guard ring
is no more than 6 mm, corresponding to a decrease of about 10 mm of
the size of the original diameter. Once this value has been reached, it is
NECESSARY TO REPLACE THE BLADE.
