3. Lift the screed and extend;
4. Release quick release couplings (1); push temper deflector plate (2) downwards
out of the bottom mounting bracket.
5. Insert extension part mounting screws (4 x (3)) and tighten by hand;
6. Align the extension part with adjusting screws (4) so that it corresponds precisely
to the extendable part or extension part. In the case of fine-grained layers, even
minimal differences will be visible in the surfacing.
7. Use the upper adjusting screws to set a "spatula-thick" gap between the exten-
sion part and the extendable screed part;
This measure compensates the screed's differences in expansion in the upper
and lower areas when heated.
8. Tighten mounting screws (3) of the extension part.
9. Mount the vibration drive shaft (5). To do this, the coupling half must be shifted on
the shaft by pressing the detent pin (6). During assembly, allow the coupling half
to engage in the required position.
Ensure that the positioning pin on the drive shaft in the screed engages in the lo-
cating bore (7) of the connecting shaft.

Prior to assembly, ensure that a crown wheel (8) is inserted into each of the coupling
halves.
10. The tamper of the extension parts is driven, as in the case of vibration, via one
shaft each with quick action coupling (9). The tamper frames of the extendable
screed part and the extension part are not bolted together. If this is not ensured
by "pins", it must be ensured when mounting the tamper drive shaft that the
tampers of the extendable screed part and the extension part operate offset by
180°, i.e. when one is located at the upper reversal point, the other must be locat-
ed at the lower reversal point. If further extension parts are mounted, it must be
ensured that the tampers also operate offset by 180° to the previously mounted
extension part.
A
In the case of 350 mm extension parts, the relevant coupling (10) / (11) must be used
on connection of the tamper and vibration drive! In the case of these shafts, the
threaded connection (12) must be released, the shaft pushed out to the required
length and the threaded connection re-installed.
Ensure that the positioning pin on the drive shaft in the screed engages in the locating
bore (13) of the connecting shaft.
11. Connect extension part heating systems to the neighbouring screed parts.
