Safety alerts, visual
presentation, and layout
While reading these instructions, you will encounter various
symbols, illustrations, and text layouts intended to help you
navigate and understand the instructions. Their meaning is
explained below.
Safety alerts:
Activities that present specific hazards (to life and limb or
possible damage to property) are indicated by safety alerts.
Always be sure to follow the instructions given in the safety
alerts.
<
DANGER
These safety alerts indicate an imminent danger.
Ignoring them will result in death or serious injury
<
WARNING
These safety alerts indicate potentially imminent
danger. Ignoring them could result in death or
serious injury
<
CAUTION
These safety alerts indicate potentially imminent
danger. Ignoring them could result in minor injury
<
NOTICE
These safety alerts indicate a potentially harmful
situation. Ignoring them could result in damage to
property or malfunctions
Illustrations:
The illustrations used depict a specific product. For other
products, they may have the function of a diagram only. This
does not alter the basic workings and operation of the product.
Text layout:
•First-order bulleted lists: Items on a bulleted list start with
a solid black dot and an indent.
–Second-order bulleted lists: If there is a further listing of
subitems, the second-order bulleted list is used.
1 Legend: A legend explains the numbered contents of an
illustration, presented as a numbered list. Items in a legend
start with a number (with no dot) and an indent.
–Second-order legend: In some cases, the numbered
contents of an image represent more than just one object.
A second-order legend is then used.
1.Instruction steps: These indicate a chronological sequence
of instruction steps. The numbers of the steps are in bold and
are followed by a period. If a new activity follows, the
numbering starts again at “1.”
–Second-order instruction steps: In some cases, it is
necessary to divide up a step into a few substeps. A
sequence of second-order instruction steps is then used.

1. Safety instructions
1.1 General safety instructions
•Putting the products into operation or operating them without
having read the instructions is prohibited. The operator must
ensure that the instructions are read and understood by all
persons tasked with working on the product or who supervise
or instruct such persons. Retain the instructions for further
use.
•The product may only be used in awareness of the potential
dangers, in proper technical condition, and according to the
information in this manual.
•Any faults that could affect safety must be remedied
according to responsibility. The supervisor must be notified
immediately in case of malfunctions outside one's individual
scope of responsibility.
•Unauthorized modifications and changes can have an
unpredictable effect on safety and operation. Unauthorized
modifications and changes are therefore 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.
1.2 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 be
performed only 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.
•Ensure proper connection of the protective conductor for
products with protection class I. Observe the specified
enclosure rating.
•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 respective
electric charge and does not have the voltage strength
necessary to withstand the effects of lightning.
1.3 General behaviour when handling the
product
•Familiarize yourself with the functions and operation of the
product. The specified assembly and operating steps and their
sequences must be observed.
•Keep unauthorized persons away.
•Wear personal protective equipment always.
•Precautionary operational measures and instructions for the
respective work must be observed.
•In addition to these Instructions, general statutory regulations
for accident prevention and environmental protection must be
observed.
•Precautionary operational measures and instructions for the
respective work must be observed. Uncertainty seriously
endangers safety.
•Safety-related protective and safety equipment must not be
removed, modified or affected otherwise in its function and is
to be checked at regular intervals for completeness and
function.
•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 occurring faults in the frame of responsibilities.
Immediately inform your superior in the case of faults beyond
your competence.
•Never use parts of the centralized lubrication system or of the
machine as standing or climbing aids.
