Suitable Products for Slicing
The following are products that can be sliced:
•All types of cold cuts (cooked, raw, smoked)
•Boneless meat (cooked or raw at a temperature of no lower than +3°C)
•Bread and cheese (those that can be sliced, such as Gruyere, Fontina, etc.)
The following are products that cannot be sliced because they could cause damage to the machine:

Unpacking
Unpack the slicer immediately after receipt. Please inspect the slicer to ensure there is no damage and that all
parts are included i.e. Knobs, Feet and Knife Removing Tool. If the machine is found to be damaged, keep all the
packaging material and contact us or contact your source of the equipment immediately.
You should receive with your slicer: 1 x Metcalfe Tasteless Oil 1 x Flat Head Screwdriver
1 x Instruction Manual 1 x Knife Removing Tool
If any of the above items were not received with your slicer, please refer to page 14 for contact details and inform
us immediately for replacements.
Please ensure that you complete the product information section on page 14.
Installation
1. Read this manual thoroughly before installation and operation. DO NOT proceed with any installation nor
operation if you have any questions or do not understand anything in this manual. Please see Metcalfe
Catering Equipment Ltd contact details on page 14 to resolve any queries you may have.
2. Make sure to clean and sanitise the entire slicer before use (see Cleaning Instructions on Page 7).
3. Select a location for the slicer that is level, smooth, solid, dry, non-skid and suitable to withstand the weight
of the slicer plus the food to be sliced.

6
Operation
1. Ensure the slicer is turned off and that the
thickness selection knob is set to “0”.
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
between the on/off 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 parts 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.

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.
Disassembly
Turn slicer off and unplug from mains.
Turn the thickness selection knob clockwise past “0” until it stops so the fence plate covers the blade.
Disassembling the table
•With the thickness selection knob on “0” pull
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.
It may be necessary to move the thickness
selection knob 1-2mm over the ‘0’ position at
the same time.
•Once fully unscrewed lift the whole of the table
and carriage from the machine.
Disassembling the centre plate (blade cover)

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.
•Loosen sharpener release knob by turning it
anti-clockwise several times (1).
•Lift
sharpener up (2), rotate it clockwise 180° (3)
and lower it into position (4).
•Tighten sharpener release knob to secure
sharpener.
•Plug in and select the start button on the slicer.
•Push the sharpening stone button and keep it
pressed for 10-15 seconds (5)
•Press the deburring button (6) for 2-3 seconds
(more could damage the blade edge).
TURN SLICER OFF before inspecting.

and close the cover.
