VIBRATION LEVEL
When used for its intended purpose, levels of vibration for the earth working machine transmitted from the oper-
ator’s seat are lower or equal to the test vibrations for the relative machinery class in compliance with ISO 7096.
The actual acceleration value of the upper limbs is less than 2.5 m/s
2
. The uncertainty for this value is 0.48 m/s
2
according EN 12096:1997.
The actual acceleration value for the body is less than 0.5 m/s
2
. The uncertainty for this value is 0.24 m/s
2
ac-
cording EN 12096:1997.
These values were determined using a representative machine and measured during the typical operating con-
dition indicated below according to the measurement procedures that are defined in the standards ISO 2631/1
and ISO 5349.
Operating condition: V-shape loading
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
• Tire pressures (for wheeled machines), tension of crawler (for crawler machines)
• Brake and steering systems
• Controls, hydraulic system and linkages
3.
Keep the terrain where the machine is working and traveling in good condition
• Remove any large rocks or obstacles.
• Fill any ditches and holes
• Site manager should provide machine operators with machine and schedule time to maintain terrain
conditions
4.
Use a seat that meets ISO 7096 and keep the seat maintained and adjusted
• Adjust the seat and suspension for the weight and size of the operator
• Wear seat belt
• Inspect and maintain the seat suspension and adjustment mechanisms
5.
Steer, brake, accelerate, shift gears (for wheeled machines), 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
• When pushing with bucket or blade, avoid sudden loading; load gradually
• Drive around obstacles and rough terrain conditions
• Slow down when it is necessary rough terrain
• Make the curve radius of traveling path as large as possible
• Travel at low speed then traveling around sharp curves
7.
Minimize vibrations for long work cycle or long distance traveling
• Reduce speed to prevent bounce
• Transport machines long distances between worksites
8.
The following guidelines can be effective to minimize risks of low back pain.
• Operate the machine only when you are in good health
• Provide breaks to reduce long periods of sitting in the same posture
• Do not jump down from the cab or machine
• Do not repeatedly handle and lift loads
