IMPORTANT
Acid solu
ti
ons, salty solu
ti
ons, disinfectants and some sterilizing solu
ti
ons
(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.
3.6 Cau
ti
ons with Stainless Steel
The Stainless Steel may present rust signs, which ARE ALWAYS CAUSED BY EXTERNAL
AGENTS, especially when the cleaning or saniti
za
ti
on 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 formati
on of a very thin protec
ti
ve coat. This
protec
tive coat is formed through the whole surface of the steel, blocking the acti
on of
external corrosive agents.
When the protec
ti
ve 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 aft
er 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.
These substances a
tt
ack the stainless steel due to the CHLORINE on its composi
ti
on,
causing corrosion spots (pitting).
Even detergents used in domes
tic 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 protec
ti
on, leave par
ti
cles that rust and react
contamina
ting the stainless steel. That is why such products must not be used for cleaning
and sani
ti
za
tion. Scrapings made with sharp instruments or similar must also be avoided.
Main substances that cause stainless steel corrosion:
Dust, grease, acid solu
ti
ons such as vinegar, fruit juices, etc., saltern solu
tions (brine),
blood, detergents (except for the neutral ones), common steel parti
cles, residue of sponges
or common steel wool, and also other abrasives.

4. General Safety Prac
ti
ces
IMPORTANT
If any recommenda
ti
on is not applicable to your equipment, please ignore it.
The following safety instructi
ons are addressed to both the operator of the machine as
well as the person in charge of maintenance.
The machine has to be delivered only in perfect condi
ti
ons of use by the Distributor to the
user. The user shall operate the machine only a
fter being well acquainted with the safety
procedures described in the present manual. READ THIS MANUAL WITH ATTENTION.
4.1 Basic Opera
ti
on Prac
ti
ces
4.1.1 Dangerous parts
Some areas of the electric device have parts that are connected or have parts connected
to high voltage. These parts when touched may cause severe electrical chocks or even be
fatal.
Never touch commands such as bu
ttons, turning keys and knobs with wet hands, wearing
wet clothes and/or wet shoes. By not following these instructi
ons operator could be
exposed to severe electrical shocks or even to a lethal situa
ti
on.
4.1.2 Warnings
The operator has to be well familiar with the position of ON/OFF Switch to make sure the
Switch is easy to be reached when necessary.
Before any kind of maintenance, physically remove plug from the socket.
Provide space for a comfortable opera
ti
on thus avoiding accidents.
Water or oil spilled on the floor will turn it slippery and dangerous. Make sure the floor is
clean and dry.
Never use a manual command (switch, buttons, lever) unadvisedly.
If any work is to be made by two or more persons, coordination signs will have to be given
for each opera
ti
on step. Every step of the opera
ti
on shall be taken only if a sign has been
made and responded.
