SAFETY INFORMATION
Vibration levels
When used for its intended purpose, levels of vibration for the earth-moving machine transmitted from the opera-
tor's seat are lower than or equal to the tested vibrations for the relative machinery class in compliance with ISO
7096.
The actual acceleration value for the hands and arms is less than or equal to 2.5 m/s². The actual acceleration
value for the body is less than or equal to 0.5 m/s².
These values were determined using a representative machine and measured during the typical operating condi-
tion indicated below according to the measurement procedures that are defined in the standards ISO 2631/1 and
ISO 5349.
Operating condition:
Excavating (Digging-loading-rotating-unloading-rotating)
Guide to Reduce Vibration Levels on Machine
The following guides can help an operator of this machine to reduce the whole body vibration levels:
1. Use the correct equipment and attachments.
2. Maintain the machine according to this manual
q Tension of crawler (for crawler machines)
q Brake and steering systems
q Controls, hydraulic system and linkages
3. Keep the terrain where the machine is working and traveling in good condition
q Remove any large rocks or obstacles
q Fill any ditches and holes
q Site manager should provide machine operators with machine and schedule time to maintain terrain con-
ditions
4. Use a seat that meets ISO 7096 and keep the seat maintained and adjusted
q Adjust the seat and suspension for the weight and size of the operator
q Wear seat belt
q Inspect and maintain the seat suspension and adjustment mechanisms
5. Steer, brake, accelerate, and move the attachment levers and pedals slowly so that the machine moves
smoothly
6. Adjust the machine speed and travel path to minimize the vibration level
q When pushing with bucket or blade, avoid sudden loading; load gradually
q Drive around obstacles and rough terrain conditions
q Slow down when it is necessary to go over rough terrain
q Make the curve radius of traveling path as large as possible
q Travel at low speed when traveling around sharp curves
