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.
In order to ensure the slicer is cleaned properly and to avoid damage, the instructions below should be followed.

back the carriage all the way to the left.
•Whilst supporting the table, turn the table
locking knob anti-clockwise all the way until
you hear the click of the pin locking into place.

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.
•Sharpening the blade lightly every few days is more effective than heavy sharpening at less frequent intervals.
•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.
Sharpening the Knife
NOTE: Before starting check that the grindstones have been cleaned.
•Turn the slicer off and rotate the thickness
selection knob clockwise until it stops and
the slicer fence plate covers the knife.
•Pull back the carriage all the way to the left.
•Clean and dry both sides of the blade before
sharpening. Please refer to cleaning
instructions.
•Lift the sharpener cover.
•Turn the sharpener towards the blade. The
sharpener is now in the correct position.
•Plug in and select the start button on the slicer.
•Push the sharpening stone button and keep it
pressed for 10-15 seconds
•Press the deburring button for 2-3 seconds
(more could damage the blade edge).
•TURN SLICER OFF before inspecting.
•Pull the fixing sharpener knob (1) in order to
unhook the sharpener from the sharpening
position and turn the body (2).
•Close the cover.
•Clean the entire slicer.

Lubricating the bottom runner guide bars (weekly)
•Move the carriage as close as possible to the
operator
•Insert the oiler in the special hole/lubricating
screw
•Squeeze the oiler so that a small amount of oil
goes into the hole
•Remove the oiler and slide the carriage 3 to 4
times.
Lubricating the transversal guide rods of the table
and end device (weekly)
•Put a small amount of oil on the rod and slide
the group 3 to 4 times.
