NOTICE
Malfunction caused by contamination. Unsuitable or contaminated
tools can reduce the function and operating life of the guidance
systems considerably. Contamination and moisture will impair
the accuracy and function of the elements considerably and lead to
an ongoing reduction in their operating life.
It must be ensured that contaminants and moisture cannot
penetrate the units.
Guidance systems should only be fitted using the tools specified.
Machines, devices or equipment that generate cutting debris or
dust must not be used in the vicinity of the fitting area.
The adjacent construction should be kept clean.

Checking
the adjacent construction
Checking the locating faces  Check the holes and locating edges for burrs.
 Remove any burrs using an oil stone.
 Check the locating heights and corner radii, Figure 1 and table .
 Correct any deviations.
 Ensure that the locating surfaces on the adjacent construction
are in full contact with the locating surfaces on the carriage and
guideway.

Checking the dimensional and
positional tolerances
 Checking the dimensional and positional tolerances of the screw
mounting and locating surfaces, see
table and Figure 2 , page 4.
 Machine the surfaces if necessary.
 If the machine bed has two defined locating surfaces,
check the parallelism of the locating surfaces.
 Checking the parallelism, flatness and perpendicularity of
the locating surfaces, see
table and Figure 3 , page 4.
At the specified maximum values, the displacement resistance
may increase.
 The tolerance for parallelism, flatness and perpendicularity is
determined by the preload class, see
table . If deviations are
identified, rework the support and locating surfaces for the guide-
ways on the adjacent construction.

Checking the scope of delivery Do not remove the units from their packaging until immediately
before fitting.
The carriage and guideway are protected by a preservative.
CAUTION
Sharp-edged counterbores. Risk of injury due to contact with
sharp edges. The adhesive strip should only be removed when
the units are fitted.

NOTICE
Open counterbores. Risk of damage to the seal lips as a result of
moving the carriage over counterbores which have not been closed
off. Do not move the carriage over counterbores that have not been
closed off. If the carriage must be moved, protect the seal lips by
sliding a spring steel strip (0,2 mm thick) between the guideway
surface and the carriage. Bend the ends up slightly at both ends of
the carriage.

The spring steel strip  must be produced by the customer.

Multi-piece guideways are packed in sets. The joints  ,  ,  are
marked consecutively,
Figure 6 .
Mount the guideways such that the numbers and letters adjacent to
each other are identical.
As standard, carriages have grease nipples similar to
DIN 71412-A-M6 for lubrication via the end faces or sides (included
in delivery)  . If a different lubrication connector was selected
when ordering, this is included instead of the standard lubrication
connector. Alternatively, carriages can also be lubricated from
above via the adjacent construction
 , Figure 7 .
Other lubrication connectors for grease or oil lubrication are avail-
able as accessories.
