Cover the working area (side walls, roof-mounted antenna and if necessary, interior equipment) with protective covers.
Tape off body with fabric adhesive tape (e.g. Tesa) in areas where the oscillating knife could damage the window glass or the paint.

Use suction cups (51 3 010) to lift out the window glass.

Always keep both suction cups dry and clean to ensure optimum adhesion on the windshield.

Secure window glass against falling out.
