Make sure to clean and sanitise the entire slicer before use (see Cleaning Instructions on Pages 8-10).
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.

Operation

Ensure the slicer is turned off and that the thickness selection knob is set to “0”.
Pull back the carriage completely (towards the operator) to the loading position.
Lift the end device up, into the rest position.
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.
Rotate the thickness selection knob anti-clockwise to the desired setting.
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.
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.
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.
After the last slice stroke, pull the carriage all the way toward 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.
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

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 center plate (blade cover)

Unscrew the center plate spindle knob (anti-clockwise) and remove it from the rear of the machine.
Lift the center plate using the knob located at the bottom.

Cleaning

Only use warm water and a mild detergent to clean all parts, using a soft, spongy cloth and nylon brush.
Do not use other metal products to scrape or remove stubborn deposits of sliced product.
Never leave any leftover product on the slicer (Clean at least once a day).
DO NOT clean the unit, or any parts of the unit in a dishwasher.
Rinse all parts after cleaning with clean water and dry with a soft cloth.
Do not use abrasive cleaners, acids, steel wool or high-pressure water jets which might damage the machine.

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 with the knife fitting between the two stones.
Tighten sharpener release knob to secure sharpener.
Plug in and select the start button on the slicer.
Push the sharpening stone button (4) and keep it pressed for 10-15 seconds
Press the deburring button (5) for 2-3 seconds (more could damage the blade edge).

TURN SLICER OFF before inspecting.

Return the sharpener body to the rest position and close the cover.
Tighten sharpener release knob.
Clean the entire slicer.
