4) If the elastomerc adapter is not perfectly into its seat,
start the coupling-tool and make the conical pin go
out completely; then, wait 30 seconds.
5) Finish the coupling cycle and push the elastomeric
adapter until it positions in the specific seat.
To smooth this operation, use a plastic-head hammer.

8.3 Removing the elastomeric adapter:
To remove the damaged elastomeric adapter (H), you must:
1) start the Coupling tool BBR 90 in jog until the mechanical expander reaches its maximum
expansion position;
2) cut the elastomeric adapter lengthwise by using a cutter.
Warning: use the cutter with due caution.

Solving main problems

9.1

Coupling sliding

If during the coupling phase an unusual sliding of the pipe is observed, to the extent that
the obtained coupling is either too short or narrow, and subsequent inserting of pipe into
the connection is difficult, clean the elastomeric adapter (H) with alcohol, make sure that
the mechanical expander (G) is screwed up to its stop, and repeat coupling.
NB: never lubricate the elastomeric adapter by using oil, grease, or other lubricating
products.
9.2

Coupling tool stop during processing (blocked pipe)

If the Coupling tool BBR 90 stops during the working cycle, follow these simple steps:
1) unscrew the mechanical expander (G) (even by a
few revolutions only) in order to release the pipe as
illustrated in the picture beside.
