3.4.1Cautions with Stainless Steel:
The Stainless Steel may present rust signs, which ARE ALWAYS CAUSED
BY EXTERNAL AGENTS, especially when the cleaning or sanitization is not
constant and appropriate.
The Stainless Steel resistance towards corrosion is mainly due to the
presence of chrome, which in contact with oxygen allows the formation of a very
thin protective coat. This protective coat is formed through the whole surface of the
steel, blocking the action of external corrosive agents.
When the protective coat is broken, the corrosion process begins, being
possible to avoid it by means of constant and adequate cleaning.
Cleaning must always be done immediately after using the equipment. For
such end, use water, neutral soap or detergent, and clean the equipment with a soft
cloth or a nylon sponge. Then rinse it with plain running water, and dry immediately
with a soft cloth, this way avoiding humidity on surfaces and especially on gaps.
The rinsing and drying processes are extremely important to prevent stains
and corrosion from arising.
IMPORTANT
Acid solutions, salty solutions, disinfectants and some sterilizing solutions
(hypochlorites, tetravalent ammonia salts, iodine compounds, nitric acid
and others), must be AVOIDED, once it cannot remain for long in contact
with the stainless steel:
These substances attack the stainless steel due to the CHLORINE on its
composition, causing corrosion spots (pitting).
Even detergents used in domestic cleaning must not remain in contact with
the stainless steel longer than the necessary, being mandatory to remove it with plain
water and then dry the surface completely.
Use of abrasives:
Sponges or steel wool and carbon steel brushes, besides scratching the
surface and compromising the stainless steel protection, leave particles that rust and
react contaminating the stainless steel. That is why such products must not be used
for cleaning and sanitization. Scrapings made with sharp instruments or similar must
also be avoided.
Main substances that cause stainless steel corrosion:
Dust, grease, acid solutions such as vinegar, fruit juices, etc., saltern
solutions (brine), blood, detergents (except for the neutral ones), common steel
particles, residue of sponges or common steel wool, and also other abrasives.

4.3 Routine Inspection
4.3.1 Advice
When checking the tension of the belts or chains, DO NOT
introduce your fingers between the belts and the pulleys and nor
between the chain and the gears.
4.3.2 Precautions
Check if motors and sliding or turning parts of the machine produce
abnormal noises.
Check the tension of the belts and chains and replace the set when
belt or chain show signs of being worn out.
When checking tensions of belts or chain DO NOT introduce your
fingers between belts and pulleys, nor between the chains and gears.
Check protections and safety devices to make sure they are working
properly.
4.4 Operation
4.4.1 Advice
Be sure your hair is not loose in order to avoid getting caught by
turning parts which could lead to a serious accident. Tie your hair well up
and/or cover your head with a scarf.
The operation performed by not trained or skilled personnel shall be
forbidden.
Never touch turning parts with your hands or in any other way.
NEVER operate machine without all original safety devices under
perfect conditions.
4.5 After Finishing The Work
4.5.1 Precautions
Always TURN THE MACHINE OFF by removing the plug from the
socket before cleaning the machine.
Never clean the machine unless it has come to a COMPLETE
STOP.
Put all components back to their functional positions before
turning it ON again. DO NOT place your fingers in between belts and
pulleys nor chains and gears.
