indicator in until the needle starts to move and push
it in an additional 5 to 6 mm (around 1/4 in). Tighten
the adapter lock nut manually.
4. To determine the TDC of the piston, proceed as follows:
o
Slowly turn the flywheel from the back to the front in
the area of the TDC while observing the needle.
Note that the needle only stops when the piston
changes direction.
o
Turn the face of the dial so that the "0" is aligned
with the needle when it stops.
o
Once more, slowly turn the flywheel from the back to
the front in the area of the TDC and set the face of
the dial to "0" until the needle stops exactly at "0"
before changing direction.
o
The "0" gives the exact TDC
