Removal
NOTICE
Module 1 and 2
The removal procedure is described here for module 1 (left). Removal for module 2 (right) is the
same.
► In the case of older Twin heads, you need to remove module 1 before you can remove mod-
ule 2. During installation, module 2 needs to be fitted before module 1.
► In the case of newer Twin heads and all Twin VHF heads, the modules can be removed
and fitted individually.
NOTICE!
When using modules with undetachable screws (1), you
may need to fit these screws on the other side, depending
on the installation position.
NOTICE
Twin and Twin VHF head
Removal and installation of the Twin VHF head follows the same procedure as that for the Twin
head. Any differences will be explicitly indicated.
► Switch off the machine, disconnect it from the power
supply and secure it to prevent unauthorized reacti-
vation. Observe the instructions in section "1.2 Pre-
paratory Work..." [ ➙ 12].
► Move the gantry into a position which allows you best
access.
► Unplug the pneumatic connection from the TwinHead
