Note: All vibration levels are in m/s
2
(meter per second squared). The expected vibration levels can be estimated
with the information in the Table to calculate the daily vibration exposure.
Notice!
– A simple evaluation of the excavator application can be used.
– For further vibration indications, refer to the indications in ISO/TR
25398 Mechanical Vibrations – Directive on Estimation of whole-
body vibration during operation of earth-moving machines.
– This publication uses measuring values of international institutes,
organizations and manufacturers.
– It contains information on whole-body vibration for operators in
earth-moving machines.
– For more information on the vibration values of the machine, refer to
Directive 2002/44/EC of European Parliament and Council on
minimum health and safety requirements regarding exposure of
workers to risks arising from physical agents (vibration).
– Your

provides information on other machine functions reducing vibration
and on safe operation
Notice!
Driectives on reducing vibration levels on earth-moving equipment
– Properly adjust machines.
– Operate machines smoothly.
– Perform correct adjustments and maintenance on the machine.
– Keep slopes in a perfect condition
Notice!
The following guidelines for reducing the whole body vibration
levels on earth-moving equipment:
– Use a machine and equipment of correct type and size.
– Follow the manufacturer’s recommendations for maintenance
：
a) Tyre
pressure.
b) Brake and steering systems.
c) Control, hydraulic system and linkage.
– Keep the job site in a good condition:
a) Remove large rocks or obstacles.
b) Fill up ditches and holes.
c) Provide a machine and enough time to keep the job site in a
good condition.
