NOISE
Sound pressure level at the operator’s station, measured according to ISO 6396 (Dynamic test method, simulat-
ed working cycle).
The maximum value of the standard deviation of the measured
time-averaged A-weighted emission sound pressure level at the
operator’s position is 2.5dB, in accordance with ISO 11201
VIBRATION - OPERATING CONDITION
(Rigid/Articulate dumper:) Work cycle (including waiting, travelling, loading, travelling with load, unloading and
travelling without load)
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 travelling 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 to go over rough terrain
• Make the curve radius of travelling path as large as possible
