permanently to the threaded shaft. This construction design
ensures, on the one hand, that the heating element will be
aligned properly in-between the components and, on the
other, that the components will be detached automatically
from the heating element after the heating stage simply
by moving the carriages apart from one another.
Slowly close the components to be jointed in on the heating
element, so they will slide into the socket and over the spigot.
When both have moved fully over or into the heating element,
the heating stage starts.
When using a cordless power tool and the optional
adapter for moving the carriages (refer to Sect. 2.3),
be sure to set the tool to its lowest speed and lowest
Important
operating force. If the tool turns too fast or exercises
too much force, you run the risk of a hand injury.
Wait for the heating time (see Sect. 5.4) to be over, then move
the carriages apart to detach the components from the heat-
ing element. Remove the heating element and close the com-
ponents in on each other, using the handwheel, to the point
where the carriages are set up at the correct fusion depth,
recognizable from the components sitting at the previously
made mark on the pipe.
After the applicable cooling time (see Sect. 5.4) is over, the new
joint can be removed from the clamps. During the cooling, do
not turn the handwheel and do not allow any external force
to be exercised on the forming joint either.
