3.3.2 Cautions 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.

4.5After Finishing The Work
4.5.1Precautions
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. Check
level of oil. DO NOT place your fingers in between belts and pulleys nor chains and
gears.
4.6 Maintenance
4.6.1Danger
Any maintenance with the machine in working situation is dangerous. TURN IT OFF BY
PULLING THE PLUG OFF THE SOCKET DURING MAINTENANCE.
4.6.2Advice
Electrical or mechanical maintenance must be done by qualified personal for such
operation.
Person in charge has to be sure that the machine is under TOTAL SAFETY conditions
when working.
5 Analysis and Problem Solving
5.1 Problem, causes and solutions
The Planetary Mixers were designed to operate with the need of minimum maintenance
but the natural wearing caused by longer use of the equipment may occasionally cause
some malfunctions.
If any such problem occurs with your mixer refer to Table 02 in which the most common
situations are listed with recommended solutions.
