2.5 Special risks
Residual risks that were determined based on a risk analysis are listed in the following section.
It is essential to follow the instructions listed here and the safety instructions in the further chapters of these instructions for use
in order to reduce possible health hazards and to avoid dangerous situations.
Electric current:
DANGER!
Danger to life from electric current!
Contact with live parts can cause imminent danger to life.
Damage to the insulation or individual components can have life threatening consequences.
For this reason:
·If the insulation is damaged, immediately switch off the power supply and arrange for repair.
·Only allow work on the electrical system to be carried out by electricians.
·Before all work, isolate the electrical system from the mains. Check that it is free of voltage!
·Before regular servicing, cleaning and repair work, switch off the power supply and secure against being
switched on again.
·Never bridge fuses or render them inoperative.
·When replacing fuses, check that the value of the amperage is correct.
·Protect live parts against moisture and conductive dust as these can lead to short circuit.
Electrical cables and power supply lines:
Danger!
Danger to life from defective lines!
Line defects can cause electric shocks and can lead to mortal injury.
For this reason:
·All connections and connections must be firmly attached and free from corrosion.
·Lines must be secured at their connection points by a strain relief.
·Only use cables for the approved intended purpose according to their quality.
·Always select the cable cross-section with sufficient thickness for the power consumption.
·Make sure the earth conductor is correctly connected.
·Protect cables and power lines against heat, oil, dust and aggressive media.
·Lay cables and lines so there is no danger of tripping. Do not route them along sharp edges or around
pointed corners. Avoid chafing, kinks and crushing.
·When using cables, do not leave them wound on rolls, drums or in loops.
·Never use cables for carrying equipment or tools!
·Do not pull out power connectors from the mains socket by their cables.
·Check cables and power connectors for their condition before use. Do not use if damaged! Have them
immediately repaired or renewed by specialists.
·Always secure cables and power lines under voltage in such a way that they cannot cause any danger or
injury and cannot be damaged.
Rechargeable batteries
WARNING!
Risk of injury due to incorrect handling of batteries!
If improperly handled, installed batteries can release hazardous substances or explode.
For this reason:
·Do not throw batteries into the fire or expose them to high temperatures. There is a risk of explosion.
·Do not touch any escaping liquid. If this liquid comes into contact with the skin, immediately rinse
copiously with water.
·If liquid gets into the eyes, immediately rinse the eyes with water for at least 10 min and immediately
contact a doctor.
·Carefully remove any escaping liquid with a suitable absorbent cloth and dispose of it in an
environmentally compatible way. Wear protective gloves!
Debris and scattered objects
CAUTION!
Danger of tripping on debris and scattered objects!
Debris and scattered objects constitute slip and trip hazards and can result in significant injury.
