Vibration Emissions
General
To assist in compliance with the European Directive 2002/44/EC, the duty specific vibration emission values
for this machine type have been provided on the following page(s) and may be used for the assessment of
risks to exposure from vibration.
Unless otherwise indicated for a specific operating condition, the vibration values are calculated with the
machine equipped with the standard attachments (for example bucket, shovel, fork, etc.) for the respective
operating condition.
The vibration values are calculated from measurements in three perpendicular axes (X, Y and Z). The highest
weighted (RMS (Root Mean Square)) value is used to specify the vibration emission.
The axis upon which the highest weighted (RMS) value occurs is shown on the vibration chart for each of the
machine operating duties, see dominant axis (X, Y or Z).

Exposure to Vibration
Exposure to vibration can be minimised through:
• Selection of the correct size and capacity of machine, equipment and attachments for a particular
application
• Use of a machine equipped with an appropriate seat, keeping the seat maintained and adjusted
• Checks to make sure that the machine is correctly maintained, reporting and correcting any faults
• Steering, braking, accelerating, shifting gears, moving the attachments and load smoothly
• Adjusting the machine speed and travel path to minimise the vibration level
• Keeping the terrain on worksites where the machine works and travels in good condition, removing any
large rocks or obstacles and filling in any ditches and holes
• Choosing routes that avoid rough surfaces and, if this is not possible, drive more slowly to avoid bumping
and jolting
• Travel over longer distances at an adjusted (medium) speed
• Avoiding bad postures, i.e. slumping in your seat, constantly leaning forward or sideways or driving with
your back twisted.
