1.3 Intended use
Feed lubricants only in compliance with the
specifications, technical data, and limits pre-
sented in this manual.
Only media approved for these types of
pump units may be used. Unsuitable media
may result in pump unit failure and po-
tentially severe bodily injury or death and
property damage. The use of synthetic and
biodegradable oils or greases requires prior
approval from SKF Lubrication Systems
Germany GmbH.
Usage is permitted exclusively in the context
of commercial business activity by profes-
sional users.
1.4 Foreseeable misuse
Any usage of the product other than as
specified in this manual is strictly prohibited.
Particularly prohibited are:
○Use outside the specified operating tem-
perature range
○Use of non-specified equipment
○Use without a pressure regulating valve
○Use in continuous operation
○Use in areas with aggressive, corrosive
substances (e.g., high ozone loads)
○in areas with damaging radiation (e.g.,
ionizing radiation)
○Use to feed, forward, or store hazardous
substances and mixtures as defined in
Annex I Part 2-5 of the CLP Regulation
(EC 1272/2008) that are marked with
hazard pictograms GHS01-GHS 09
○Never use any part of the centralized
lubrication system as a stand or step or
for climbing.
○Use to feed / forward / store gases,
liquefied gases, dissolved gases, va-
pors, or fluids whose vapor pressure
exceeds normal atmospheric pressure
(1013 mbar) by more than 0.5 bar at
their maximum permissible operating
temperature
○Use in another, more critical explosion
protection zone
○Use with a missing, damaged, or improp-
erly performed subsequent finish The
finish must meet the requirements of
standards applicable to ATEX.
