Sound Level Information for Machines in European Union Countries and in Countries that Adopt the "EU Directives"
The declared operator sound pressure level that is measured according to static test procedures and conditions that are specified in "EN500-2006" is 85 dB(A) for a machine that is equipped with a canopy. The swivel seat was in the straight ahead position.The declared average exterior sound pressure level is 106 dB(A). The exterior sound power level was measured according to the static test procedures and conditions that are specified in "2000/14/EC"."The European Union Physical Agents (Vibration) Directive 2002/44/EC"
Vibration Data for Asphalt Paver
Information Concerning Hand/Arm Vibration Level
When the machine is operated according to the intended use, the hand/arm vibration of this machine is below 2.5 m/s2.Information Concerning Whole Body Vibration Level
This section provides vibration data and a method for estimating the vibration level for track-type excavators.The expected vibration levels can be estimated with the information in Table 1 in order to calculate the daily vibration exposure. A simple evaluation of the machine application can be used. For typical operating conditions, use the average vibration levels as the estimated level. With an experienced operator and smooth terrain, subtract the Scenario Factors from the average vibration level in order to obtain the estimated vibration level. For aggressive operations and severe terrain, add the Scenario Factors to the average vibration level in order to obtain the estimated vibration level.

Vibration levels are influenced by many different parameters, such as: operator training, operator behavior, operator mode and stress, job site organization, job site preparation, job site environment, job site weather, job site material, machine type, quality of the seat, quality of the suspension system, attachments and condition of the equipment.Properly adjust machines. Properly maintain machines. Operate machines smoothly. Maintain the conditions of the terrain. The following guidelines can help reduce the whole body vibration level:
Use the right type and size of machine, equipment, and attachments.
Maintain machines according to the manufacturers recommendations: tire pressures and brake and steering systems, controls, hydraulic system, and linkages.
Keep the terrain in good condition by performing the following items: remove any large rocks or obstacles, fill any ditches and holes and provide machines and schedule time in order to maintain the conditions of the terrain.
Keep the seat maintained and adjusted by doing the following: adjust the seat and suspension for the weight and the size of the operator and inspect and maintain the seat suspension and adjustment mechanisms.
Perform the following operations smoothly: steer, brake, accelerate and shift the gears.
Move the attachments smoothly.
Adjust the machine speed and the route in order to minimize the vibration level by doing the following: drive around obstacles and rough terrain and slow down when necessary to go over rough terrain.
Minimize vibrations for a long work cycle or a long travel distance by doing the following: use machines that are equipped with suspension systems, if no ride control system is available, reduce speed in order to prevent bounce and haul the machines between workplaces.
Less operator comfort may be caused by other risk factors. The following guidelines can be effective in order to provide better operator comfort: adjust the seat and adjust the controls in order to achieve good posture, adjust the mirrors in order to minimize twisted posture, provide breaks in order to reduce long periods of sitting, avoid jumping from the cab, minimize repeated handling of loads and lifting of loads and minimize any shocks and impacts during sports and leisure activities.
