Ensure the buer has been secured into its installation position.
Oleo recommends a bolt size M12 for fixing and all four fixing positions are used.
Ensure this area at the base of the buer, shown in Figure 2 is supported.
At this point the buer is still compressed in its transportation state, now the buer
can be released by removing the transportation bolt. The following is the
recommended removal procedure.
For a controlled release, lower the elevator car (or equivalent) onto the buer. This
mass must be at least equivalent to the minimum mass of the specified buer.
Minimum mass of the buer show in the table below:

5BUFFER INSTALLATION PROCEDURE (Continued)
To release the plunger, undo the transportation
bolt. (GREY in Figure 3).
Discard the transportation bolt and spacer (GREY
in Figure 3).
If used, remove the elevator car (or equivalent) and
this will control the recoil of the buer.
After periods of being held in the compressed
state during transportation and storage, the
plunger may require assistance to initially extend.
This should be done using rubber dead blow
mallet to tap the underside of the buer top plate
(GREEN in Figure 3) at 90 degree intervals until
the plunger extends.
Once fully extended and stroked the buer will
perform as designed.
Buers are to be fitted vertically parallel to guide
rail +/- 5mm.
