Information

It is generally possible to remove the windscreen with the cutting wire and the optional cutting thread contained in the tool set.
In contrast to cutting threads, however, the cutting wire has the following disadvantages:
Danger of injury when tearing off the cutting wire.
Danger of damage to materials on paint surfaces and interior equipment parts.
For the reasons outlined above we recommend using the cutting thread.

WARNING: Vehicle windows removed and installed incorrectly

Danger of cuts
Risk of eye injuries

→ Wear personal protective gear.

→ Always shut off power supply when replacing cutting knife.

NOTE: Windscreen removed incorrectly

Risk of damage to vehicle identification number (VIN) label
Risk of damage to paintwork

→ When cutting out the windscreen, make sure that the label with the vehicle identification number (VIN) is not damaged.
