5. INSTALLATION
5.1 UNPACKING AND ASSEMBLY
1. When the slicer has been unpacked and removed from its shipping carton, it should be checked carefully for
any damage that may have occurred during shipment. Do not plug in the power cord or attempt to operate the
slicer prior to this examination. Any damage during shipment must be reported to the freight company and sales
agent within 3 days of receiving goods. No claims accepted after this period.
2. Carefully check all slicer components such as the product table, pusher, sharpener, thickness control knob,
etc., to make certain they move freely and that there are no obstructions. Turn the thickness control knob as far
right as possible. Lubricate the pusher slide bar (on the product table) and the square and round table support
rails (underside of slicer) with Food Grade Machine Oil / Grease. Vegetable oil should never be used. Vaseline
may be used if no suitable grease can be obtained.
3. Install the Slicer on a firm, level surface. The feet can be adjusted to prevent rocking on a slightly uneven
surface.
4. National Standards exist which outline position, spacing and ventilation requirements for appliance
installation. Please consult the relevant Standard for requirements on installation space. We recommend a
minimum, well ventilated air gap of 100mm. Please ensure a gap of at least 100mm is given or more as
specified in the local Standard.
5.2 TESTING PRIOR TO OPERATION
1. Make sure that the ON/OFF switch is in the OFF position, and the thickness control knob is turned as far to the
right as possible. In this way the gauge plate is in a position that the knife is not exposed during testing.
2. Plug power cord into correct electrical outlet, and ensure the mains cable does not cause a tripping hazard.
3. Turn the slicer ON and check for smooth knife rotation. Turn the slicer OFF.
4. Slide Product Table back and forth holding on to the Product Table Handle. If there is any rough operation or
obstruction, shut off, unplug power cord and call service for assistance.
6. CLEANING AND LUBRICATING
The machines must be properly cleaned at least once a day; if necessary even more.
If the machines have not been used for a while they must be cleaned before use as well.
6.1 PRODUCT TO BE USED
Only use hot water and a biodegradable detergent for dishes with a 7-8 PH, at a temperature of no lower than
30°C using a soft, spongy cloth and a semi-rigid nylon brush for the plate and the sharp food press.
WARNING: For cleaning the sharp areas of the plates, the food press and the blade, we recommend using
protective gloves.Rinse well with a lot of hot clean water and dry with a soft cloth or a spongy material.
Do not clean slicer with running water from a tap or hose, etcs.
6.2 CLEANING SHARPENING STONES
Each time the sharpener is used, the sharpening stones should be examined for cleanliness. Turn off slicer, close
the gauge plate, unplug power cord and remove sharpener. If there is evidence of fatty or metallic build-up in the
stones, they must be cleaned. Otherwise, they will not have the abrasive quality necessary to sharpen.
Clean stones with a semi-rigid nylon brush. Now replace the sharpener and lock in position.
Dirty Stones Cannot Sharpen!
IF THE SHARPENING STONES HAVE BECOME COATED WITH FOOD FATS OR METALLIC BUILD-UP,
THEY WILL NOT SHARPEN EFFECTIVELY.
REMOVING THE SHARPENER EXPOSES THE KNIFE. DO NOT LEAVE UN-ATTENDED.
6.3 LUBRICATION
Before lubricating, disconnect the machine from the power supply and turn the slice thickness regulator to zero.
Every week put a small amount of oil (a few drops) on the transversal sliding bar of the handgrip and on the
longitudinal sliding bar of the plate support inside the base of the machine.
Manually slide the groups and clean as necessary removing any excess oil.
ATTENTION: Use only Food Grade Machine Oil / Grease or Vaseline.
DON'T USE VEGETABLE OILS!

7. SHARPENING INSTRUCTION
1. Switch OFF the power.
2. Unplug the slicer.
3. Turn the thickness control knob to the clockwise to place the gauge plate in the fully closed position.
4. Clean the knife completely. Always clean from the centre towards the outside edge of the knife. Never move
your hand towards the edge of the knife. Replace the centre plate knife guard.
5. Loosen the sharpener locking knob, raise and rotate the sharpener until the stones sit with one on each side
of the knife. Re-tighten the knob to hold the sharpener in its sharpening position.
6. Switch ON the power.
7. Press the sharpening stone push-button to bring the stone against the knife and hold it for five to 10
seconds and release.
8. Press the deburring stone pushbutton to bring the stone against the knife and hold it for two or three
seconds and release.
9. Switch OFF the power.
10. Return the sharpener to its stored position and lock in place.
11. Clean slicer before slicing product.
Your slicer is now sharpened, cleaned and sanitized-ready to use.
KNIFE SHOULD BE SHARPENED AT A MINIMUM ON A WEEKLY BASIS.
DO NOT SHARPEN A KNIFE THAT IS NOT CLEAN. YOU WILL DAMAGE THE SHARPENING STONES
AND BE UNABLE TO SHARPEN THE KNIFE.
8. TROUBLESHOOTING
Should your slicer fail to function properly, here are a few things you can check before calling FOR ASSISTANCE.
Product not slicing properly; thick and thin or irregular slices.
1. Is the knife sharp? If not, sharpen according to instructions. Remember, only sharpen a clean knife.
2. Does the product size exceed the capacity of the slicer? Too large a product may rub against the sharpener
assembly causing interference to normal slicing.
3. Is the product positioned correctly and held securely on product table? If not, product may move or rotate
during slicing operation resulting in partial or thick and thin slices.
4. Are all components held securely in place? A loose product table or pusher can cause inconsistent slices.
Knife not sharpening
1. Are sharpening procedures being followed exactly as explained in this manual?
2. Are sharpening stones clean? If not, clean according to instructions.
3. Is the knife clean? If coated with food fats, sharpener stones cannot sharpen. Clean per instructions.
4. Are sharpening stones making solid contact with the knife? If not, have a service engineer adjust them to the
proper height.
5. Are sharpening stones severely worn and not making contact with the knife? Are the sharpening stones
cracker or chipped? If so, have a service engineer replace and adjust the new stones to the proper position for
best sharpening results.
Electrical failure
1. Is slicer fully plugged into a properly grounded outlet? If properly connected, the red or white warning light
should be on when switch is in the ON position.
2. Inspect power cord. Has it been damaged, cutting off electrical flow? If so, call for service assistance to
replace the power cord.
3. Is ON/OFF switch in the ON position?
4. Are you getting electricity from the wall outlet? Check by plugging in another piece of equipment with the
same electrical requirements. Also, check circuit breaker or fuse.
5. If you are getting electrical power and your slicer is still not operating, contact service for assistance.
Thickness control knob not operating gauge plate
1. If the thickness control knob is not opening and closing the gauge plate properly, it is a sign that the internal
mechanism has suffered some loss of adjustment. Do not try to adjust the mechanism yourself. Call service for
assistance.
If correction of any of the above conditions does not result in a functional slicer, call service for assistance.
