Note:

Mark the direction of rotation of the toothed belt
with chalk or felt pen before removing. A used
belt can break if it rotates in the wrong direction
when reinstalled.
The toothed belt tensioning element is oil-
damped and can therefore only be compressed
slowly by applying constant pressure.

- Using a hex key, turn toothed belt tensioning roller -1- clockwise 8 mm
in direction of arrow until tensioning lever -2- compresses tensioning
element -3- sufficiently to enable special tool T 400 11 to be fitted in
drilling and in plunger.
- Insert special tool T 400 11, release toothed belt tensioning roller.
- Take off toothed belt.
