line with official regulations.
Soak up expired operating materials using absorbent material, pour them into a liquid-tight container specially
labelled for this purpose and dispose of them in line with official regulations.
3.6.15. Potential hazards at the device
Noise can lead to health problems
The noise generated by the device while in operation can lead to
health conditions such as hearing impairment, deafness or
tinnitus. When using the device at high speed, the noise level is
also increased.
Before commissioning the device, first assess the
danger posed by noise. Specify and use suitable
hearing protection based on the environmental
conditions, working times and work/operating
conditions of the device.
Specify a regulation for the use of hearing protection
and for the duration of work.
Remove the hearing protection when driving on the road.
Liquids under high pressure
The following liquids are highly pressurised:
Hydraulic oil
High-pressure fluids which leak under pressure can penetrate the
skin causing serious injury.
If you suspect that a pressure system may be
damaged, shut down and secure the machine
immediately and then contact a qualified specialist
workshop.
Never attempt to trace the source of leaks with your bare hands. Even just a pin hole can cause serious personal
injuries.
Use suitable materials when searching for leaks. (for example, a piece of cardboard)
Keep your body and face well away from leaks.
If a fluid penetrates the skin, it must be removed immediately by a doctor who is familiar with such injuries.
Otherwise serious infections may result.
Doctors unfamiliar with this type of injury should reference a knowledgeable medical source.
Prior to recommissioning, check the leak-tightness of the hydraulic system!
