The emergency buffers 1 ... 3 are intended to prevent material damage re-
sulting from faulty commissioning or program errors. They are not intended
to be used as continual cushioning elements.
2. General instructions
2a. Working stroke
Information
For fastening the emergency buffers 1 ... 3:
Observe the supplied assembly instructions of the retainers 5 ... 7.
The subsequent installation of emergency buffers 1 .... 3 reduces the
working stroke.
Check whether the remaining working stroke is sufficient for your applica-
tion.
Working stroke = effective stroke minus emergency buffer
2b. Coupled axes
Note
When operating with two coupled axes:
Only uniform impact on both sides produces stresses without torsion.
Make sure that cushioning components of the same type
(emergency buffers 1 … 3 or shock absorbers) are attached in the same
position on the guide and drive axes.

3. Preparing for assembly
Degrease the surface of the retainers 5 … 7 intended for gluing onto the
emergency buffer 1 … 3 with a mild cleanser (e.g. petroleum ether).
Note
The protective foil 4 is silicon-coated for functional reasons and so contains
PWIS
1)
.
The silicon is in bound form and is not usually transferred when the protec-
tive foil is touched. The silicon will be dissolved if brought into contact with
solvents.
Observe the following when pulling off the protective foil 4:
– avoid all contact of the protective foil 4 with solvents;
– remove the protective foil 4 immediately from the critical area.
If these safety measures are complied with, the emergency buffer 1 … 3 is
PWIS
1)
-free in the mounted state.

Pull off the protective
foil 4.
Mount the retainer 5 ... 7 according to the supplied assembly instruc-
tions.
1)
PWIS = paint-wetting impairment substances
