Unlocking the transport protection

: The front window counterweight [1] is secured to the
device backpanel to protect it from transport damage.
CAUTION – Unlocking the counterweight!
The counterweight at the device backpanel
compensates for the weight of the front win-
dow.
The front window must not be moved unless:
•
the counterweight has been unlocked so
that it can move freely,
•
the protective packaging has been removed
from the front window,
•

on a sufficiently stable substructure or onto
a stand.
Crushing hazard - after unlocking, keep hands
and fingers away from the motion range of the
counterweight!

•
Keep the counterweight retaining screws for later transports.
