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. 

→ Wear personal protective gear.

→ Always shut off power supply when replacing cutting knife.

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

Information
