The vibration information and the calculation
procedur
e is based on “ISO/TR 25398 Mechanical
Vibration - Guideline for the assessment of exposure

ing machines”. Harmonized data is
measured by international institutes, organizations
and manufacturers.
This literature provides information about assessing
the whole body vibration exposure of operators of
earthmo
ving equipment. The method is based on
measured vibration emission under real working
conditions for all machines.

Guards
(Ope rator P rotection)
SMCS Code: 7000; 7150; 7150-MCH; 7325
There are different types of guards that are used to
protect the operator. The machine and the machine
application determines the type of guard that should
be used.
A daily inspection of the guards is required in order to
check for structures that are bent, cracked or loose.
Never operate a machine with a damaged structure.
The operator becomes exposed to a hazardous
situation if the machine is used improperly or if poor
operating techniques are used. This situation can
occur even though a machine is equipped with an
appropriate protective guard. Follow the established
operating procedures that are recommended for your
machine.
