Sound Level Information for Machines in Eurasian Economic Union Countries
The information below applies to only the machine configurations that have the "CE" mark on the Product Identification Plate.The declared dynamic operator sound pressure level is 76 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. The sound level may vary at different engine cooling fan speeds. The cab was properly installed and maintained. The measurement was conducted with the cab doors and the cab windows closed.The declared sound levels listed above include both measurement uncertainty and uncertainty due to production variation."The European Union Physical Agents (Vibration) Directive 2002/44/EC"
Vibration Data for Off-Highway Trucks
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 meter per second squared.Information Concerning Whole Body Vibration Level
This section provides vibration data and a method for estimating the vibration level for off-highway trucks.Note: Vibration levels are influenced by many different parameters. Many items are listed below.
Operator training, behavior, mode and stress
Job site organization, preparation, environment, weather and material
Machine type, quality of the seat, quality of the suspension system, attachments and condition of the equipmentIt is not possible to get precise vibration levels for this machine. 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.Estimate the vibration levels for the three vibration directions. 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.Note: All vibration levels are in meter per second squared.

This publication uses data that is measured by international institutes, organizations and manufacturers. This document provides information about the whole body exposure of operators of earthmoving equipment. Refer to Operation and Maintenance Manual Supplement, SEBU8257 for more information about machine vibration levels.The Cat suspension seat meets the criteria of "ISO 7096". This represents vertical vibration level under severe operating conditions. This seat is tested with the input "spectral class EM1". The seat has a transmissibility factor of “SEAT<1.1”.Guidelines for
