2.=Throttle trigger =036 QS only

A modified version of throttle trigger
1125 180 1501 is now available. Its function has
been further enhanced by fitting a washer

row).

The new version of the throttle trigger should
always be installed in the case of a repair.

Most of these PDFs embed fonts with a shifted character map, so the text above was recovered rather than copied — read it as a faithful but imperfect transcription, and treat the page image above each block as the authority where the two disagree — the figures exist only there, because they are vector drawings that text extraction cannot keep.
