3. SAFETY
ven though the machine's operation is simple
and safe, it is essential that all grain cart loading,
unloading and transport operators and
supervisors have an in-depth knowledge of the
contents of this user's manual. In this way,
situations of danger will be avoided for the
operator, for third parties and for goods in the
surrounding area.
There must be a written record of when the
operators are trained in every detail of the
machine's operation.
3-a. Attitude Toward Safety
Just as with the operation of any other machine,
the most important factor for preventing
accidents of any kind is the positive attitude of
operators and supervisors toward safety. As well
as following the manufacturer's
recommendations, the habit must be developed
of foreseeing and analyzing every possible
contingency that could arise during the
operation of the machine. ven though it is
impossible to foresee all possible situations, this
habit helps to prevent the majority of hazardous
situations.
3-b. "ATTENTION" Symbol and Signal
Words
Throughout the present manual, the
"Attention" symbol is used to indicate
risk situations for the operator, the
machine, other equipment or other
people.
This symbol will appear together with certain
signal words depending on the relative
seriousness of each risk situation.
DANGER: This identifies an imminent
hazardous situation whose consequences may
cause death or serious injuries if not avoided.
WARNING: This identifies a potential
hazardous situation whose consequences may
cause death or slight to moderate injuries if not
avoided.
IMPORTANT: This describes a particular
situation where the machine could be
damaged or its normal operation could be
affected.
3-c. Personal Protective Equipment
Micrón Fresar S. R. L. recommends the use of
the following Personal Protective quipment in
order to avoid any possible injury:
3-d. Safety Warnings
On different parts of the machine and on its
accessories you will find decals with accident
prevention symbols, which must be considered
as part and extension of the instructions detailed
in this manual. Special care must be taken to
ensure these decals are present and legible
during the entire working life of the machine.
If for any reason any of these gets lost or
becomes illegible through wear, it is important to
substitute it immediately indicating its
corresponding code. To ask for a replacement
decal, please contact either the manufacturer
using the information given in 4-b. "Contact
information", or your local Technical
Representative.
3-e. Risk Analysis
The risk situations that typically arise during the
operation of this machine are detailed below.
Recommendations are made that are of vital
importance for the safety of the machine
operators, of other workers nearby, and the
machine itself.
The pictograms used are taken from IRAM
standard 8075 "Tractors, agricultural and
forestry and green space maintenance
machinery - Safety signs and hazard pictograms
