4) If the elastomerc adapter is not perfectly into its seat,
start the coupling-tool and make the conical pin go
out completely; after that, wait 30 seconds.
5) Finish the coupling cycle and push the elastomeric
adapter until it positions in the specific seat. In order
to make this operation easier, use a plastichead ham-
mer.

8.2 Replacing the elastomeric adapter from ø 40 to 75 mm:
use of the splitting wrench (art. 50832)
1) Completely introduce the elastomeric adapter into the
tips of the splitting wrench (Picture 13).
2) Turn the handle to open the splitting wrench jaws
(Picture 14) until the desired diameter shown on the
gauge is reached (viz. Ø 50), and observe holding
times (see table at the bottom of the page).
3) Set the splitting wrench at rest. Take the expanded
elastomeric adapter and introduce it - rapidly and
following its coninginto the mechanical expander by
pushing it flush with the same expander. To smooth
this operation, use a plastic-head hammer.
NB: Make sure that the elastomeric adapter and the
mechanical expander have the same diameter (see the
diameter-colour correspondence in the table).
