USE
1. Disassemble the spark plug, insert the tool in the spark plug
thread and fix.
2. Turn knurled sleeve (7) until the -0- marking is positioned
opposite the marking line on the bottom part of the tool.
3. Loosen fixing screw.
4. Turn the crankshaft in the “normal” direction of
rotation until the piston is positioned TDC. The TDC
position is reached once stylus (6) protrudes the
furthest out of the tool.
5. Tighten the fixing screw.
6. Turn the crankshaft a half a rotation against the
“normal” direction of rotation.
7. Turn the knurled sleeve (7) to the right by the
necessary value in mm (pre-ignition in mm).
8. Carefully turn the crankshaft in the “normal” direction of
rotation until until the piston crown rests against stylus
(6).
9. Now the piston is located in front of the TDC by the set
value in mm.
