information in this manual.
Any faults that could affect safety must be remedied according to responsibility. The supervisor must be notified immediately
in the event of malfunctions outside one's individual scope of responsibility.
Unauthorised changes may have unexpected effects on the safety and performance of the product, which is why making such
changes is prohibited. Only original SKF spare parts and SKF accessories may be used.
Any unclear points regarding proper condition or correct assembly/operation must be clarified. Operation is prohibited until
issues have been clarified.
The components used must be suitable for the intended use and the applicable operating conditions, e.g. max. operating
pressure and ambient temperature range, and must not be subjected to torsion, shear, or bending.

General electrical safety instructions
Electrical devices must be kept in proper condition. This must be ensured by periodic inspections in accordance with the
relevant applicable standards and technical rules. The type, frequency, and scope of the inspections must be determined in
accordance with the risk assessment to be carried out by the operator. Work on electrical components may only be performed
by qualified electricians. Connect the electrical power only in accordance with the valid terminal diagram and in observance of
the relevant regulations and the local electrical supply conditions.
Work on electrical components may be performed only in a voltage-free state and using tools suitable for electrical work. Do
not touch cables or electrical components with wet or moist hands.
Fuses must not be bridged. Always replace defective fuses with fuses of the same type.
The proper connection of the protective conductor must be ensured for products of protection class I. The specified enclosure
class must also be taken into account.
The operator must implement appropriate measures to protect vulnerable electrical devices from the effects of lightning during
use. The electrical device is not furnished with a grounding system for the dissipation of the electric charge and does not have
the voltage strength necessary to withstand the effects of lightning.
General behaviour when handling the product
Familiarise yourself with the functions and operation of the product. The specified assembly and operating steps and their
sequences must be observed.
Keep unauthorised persons away.
Always wear personal protective equipment.
Precautionary operational measures and instructions for the work must be observed.
In addition to these Instructions, general laws and regulations for accident prevention and environmental protection must be
observed.
Precautionary operational measures and instructions for the work must be observed. Uncertainty seriously endangers safety.
Safety-related protective and safety equipment must not be removed or modified and its function must not be altered and its
condition and operation must be checked at regular intervals.
If protective and safety equipment has to be dismantled, it must be reassembled immediately after finishing the work, and then
checked for correct function.
Remedy any faults that are within the scope of your responsibilities. Immediately inform your superior in the case of faults
beyond your competence.
Never use parts of the centralised lubrication system or of the machine as standing or climbing aids.
