7. Instructions for use
Remove the conical pin protection (E) and set the mechanical expander (G) of the desired
1.
working diameter on the Coupling tool, checking that it has been screwed up to the stop.
NB1: In order to perform this operation, the equipment must be in a rest position.
NB2: Check that the elastomeric adapter (G) is mounted on the mechanical expander (H) and that no tears or
breaks are evident on the elastomeric adapter.
The good shape of couplings is granted only if the adapter is in a good condition (for adapter removal and
replacement, see "Replacing of the elastomeric adapter"). Do not use grease, soap, lubricating or sliding
products of any kind on the elastomeric adapter (H). Warning: When mounting the mechanical expander,
make sure that the equipment is not connected to the power supply source (battery or outlet).
2. Cut the pipe perpendicularly and with care, then insert the cap into it.
NB: To avoid damage to pipe heads, make sure that the shearing or pipe-cutting blades are in good working order. Blades are in good working order.
YES
3. Insert the pipe into the mechanical expander (G) pushing it up to the stop.
Warning: The pipe must be in axis and parallel to the expander.
4. Press the starting button (B-2) for 2-3 seconds: the cycle will automatically continue. The belling time varies from 6 to 8 seconds.
NB: The mechanical expander (G) has anti-slide teeth. When performing belling (expansion of pipe), a minimum shortening of bell occurs. This does
not alter the proper bell length.
Warning: Once the coupling cycle is over, the equipment goes back to its initial position, ready to perform the next working cycle. Otherwise, press the
emergency stop button (B-1).
5. Clutch the connection into the coupling obtained by pushing it up to the stop.
6. Screw the cap up to the anti-unscrewing safety notch (use the special wrench series).
NB: The connection may be disassembled by unlocking the cap by means of the special wrench. DO NOT RE-USE caps already locked.
7. In order to change pipe diameter, unscrew the mechanical expander (G) and set the one with the desired diameter, following the
steps described in section 1.
8. When you put the coupling tool BE90 18V in its case, be sure that the conical pin is back into return position.
8. Replacing the elastomeric adapter
The elastomeric adapter (H) must be replaced only when it has evident signs of tearing (cuts or breaks).To replace it, just follow the specified
instructions and use the suitable tools.
8.1 Replacing the elastomeric adapter from ø 14 to 32 mm: use of the splitting wrench
1. Completely introduce the elastomeric adapter into the tips of the splitting wrench following its coning.
2. Open the splitting wrench slowly and press hard and repeatedly pausing a few seconds at each opening.
Repeat the operation several times rotating the elastomeric adapter (picture 9) in order to obtain a uniform
expansion.
3. Set the splitting wrench at rest. Take the expanded elastomeric adapter and introduce it - rapidly and
following its coning- into the mechanical expander by pushing it flush with the same expander. In order to
make this operation easier, 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).
