c.Provide machines and schedule time in order to maintain the conditions of the terrain.
4.Use a seat that meets “ISO 7096”. Keep the seat maintained and adjusted.
a.Adjust the seat and suspension for the weight and the size of the operator.
b.Inspect and maintain the seat suspension and adjustment mechanisms.
5.Perform the following operations smoothly.
a.Steer
b.Brake
c.Accelerate.
d.Shift the gears.
6.Move the attachments smoothly.
7.Adjust the machine speed and the route in order to minimize the vibration level.
a.Drive around obstacles and rough terrain.
b.Slow down when it is necessary to go over rough terrain.
8.Minimize vibrations for a long work cycle or a long travel distance.
a.Use machines that are equipped with suspension systems.
b.Use the ride control system on wheel scrapers.
c.If no ride control system is available, reduce speed in order to prevent bounce.
d.Haul the machines between workplaces.
9.Less operator comfort may be caused by other risk factors. The following guidelines can be effective in order to provide better operator comfort:
a.Adjust the seat and adjust the controls in order to achieve good posture.
b.Adjust the mirrors in order to minimize twisted posture.
c.Provide breaks in order to reduce long periods of sitting.
d.Avoid jumping from the cab.
e.Minimize repeated handling of loads and lifting of loads.
f.Minimize any shocks and impacts during sports and leisure activities.

The vibration information and the calculation procedure is based on “ISO/TR 25398 Mechanical Vibration - Guideline for the assessment of exposure to whole body vibration of ride on operated earthmoving 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 earthmoving equipment. The method is based on measured vibration emission under real working conditions for all machines.
You should check the original directive. This document summarizes part of the content of the applicable law. This document is not meant to substitute the original sources. Other parts of these documents are based on information from the United Kingdom Health and Safety Executive.
Refer to Operation and Maintenance Manual, SEBU8257, “The European Union Physical Agents (Vibration) Directive 2002/44/EC” for more information about vibration.
