Plugging the branch connection:
Once the mains has been perforated, move the chuckshaft up by turning the machine
body counterclockwise until the hole saw is positioned in the upper part of the dome.
Carefully open the venting valve to remove chip residues. Next, close the valve again.
Now carry out the plugging to facilitate disassembly of the machine and the subsequent
connection to the branch connection.

To do so, the slot in the saddle for the introduction of the spatula must be fully
accessible. Slightly raise the clamp-gasket assembly of the saddle closure to keep it from
interfering with the handle of the spatula during the introduction. See
Figure 10
.
The clamp-gasket assembly is delivered flush with the upper face of the
saddle and with the fastening bolt untightened.
Place the pivoting shaft of the spatula in the opening of the saddle (use the small spatula
to plug branch connections with threaded outlets of 3/4” to 1½” and the large spatula
for branch connections with 2” threaded outlet). Insert the spatula all the way to the
bottom through the slot of the saddle. See
Figure 11
.

Disassembly of the machine and accessories:
Before carrying out the disassembly of the drilling machine, check the tightness of the
spatula by opening the venting valve. There should not be any fluid overflow, unless it
is the amount remaining in the interior before fitting the spatula. Correct the position of
the spatula in case of leak or determine the causes of any possible loss.
Once the check is complete, return the venting valve to the closed position.
Disassemble the saddle adapter and drilling machine using the spanner designed for this
purpose.
