Forch Power Drive Bedienungsanleitung Seite 16

When reaching the upper right corner with the
cutting string, change your position again and
move to the upper left corner, then continue
to the lower left corner and proceed with the
cutting operation as described before.
In order to cut out the last piece of the bond,
place the device in the lower middle of the
windscreen and continue the cutting
operation until the thread point is reached.
You can now detach the cutting-out device
from the windscreen, remove the positioning
hook and take the windscreen out.
Only use the cutting string once – for safety and warranty reasons!
