Useful information
Removal is difficult if the vehicle's windscreen is very cold or the adhesive bead is very old . By heating the screen with a hot air
gun (up to max . 90°C), the adhesive bead becomes soft and thus easier to separate . It is also practical to heat up the awl in such
instances .
Before cutting out, inspect the new screen where clips or spaces might be . If the screen is required for later re-installation, the
cord must be fed below any seal that may be present to prevent damage to the seal .
Removing side windows
Side windows can be removed if the windscreen removal device can be attached to the screen with the suction cup .
Due to spatial conditions the angular gear is required .
Troubleshooting
Problem
The windscreen removal cord only goes
through the adhesive bead with great
difficulty or tears off .

windscreen properly
The vacuum drops and the red safety
ring becomes visible
Cause

hardened as a result

the chassis number

Solution

bead with the hot air gun

them with a "tug"
In the case of large clips, thread the cord
behind the clip again
Heat up partially with the hot air gun
Set the tool up so that you get a sharp
angle .
