Accessories required for operation (not included): 

Cordless screwdriver/drill with at least a 10.8 V Li-ion battery or a 18 V Ni-Cd battery and variable speed.

NOTE: Always use a low gear setting.
NOTE: Damage as well as ergonomie and health-endangering harm are minimized with the "Spider" disassembly system.
WARNING: Follow safety instructions. Refer to SAFETY INSTRUCTIONS FOR WORKING ON VEHICLES WITH AIRBAG SYSTEMS  for working on vehicles with airbag systems (risk of injury).

Attention! 

Handle sharp-edged tools with care (risk of damage to the head airbag and the window glass).

Attention! 

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

Suction cup may not be applied at the damaged point (crack in window glass).

The bearing bushes of the shaft (spindle) must always be lubricated.

Always wear safety goggles and protective gloves for your own safety.

NOTE: The TRAINING VIDEO schematically shows the method for removing the windshield.

The procedure for disassembly of the windshield is described below as an example.

Deviations in the work procedure can be found in the vehicle-specific repair instructions.

General 

A cord approx. 6.8 m long is used to cut through the adhesive bead.

The cord length to be used is identified by a short red mark (A) approx. 5 cm.

The part of the cord laid outside around the window glass (approx. 5 m) is identified with a long red mark (B) (approx. 18 cm).

The marks are applied so that the cord has to be pulled from the inside to the outside.

If required, unwind cord from roller (1) up to the second red mark (approx. 5 cm long) and cut off.

Make sure the cord lies below the window glass at all four corners.

Check that the cord is not caught on clamps or body.

Secure window glass on outside with adhesive tape against sliding.

Normally, the adhesive bead is cut through counter-clockwise seen from the passenger compartment.

Cutting out procedure

Optimum cutting is guaranteed when the cord is at an acute angle to the adhesive bead. There is a risk of the cord ripping if the angle is too obtuse.

The separation device must be positioned correspondingly to achieve the appropriate angle.

If required, over trim panel components with plastic protection.

Guide cord with plastic protection around sharp-edged positions.

Cut through adhesive bead up to bottom area of A-pillar.

Turn back cordless screwdriver (4) approx. 2 rotations and remove.

Additional resetting may be required for very curved window glass.

It is possible to reuse the cord. When a cord is used many times the risk of ripping increases.

Dirt contamination must be avoided when a cord is reused.
