• If the glow plug is still intact and does not unscrew using the
standard spanner, use the Torx spanner supplied with the kit
(ref. 1952 003 261), and try to unscrew acting on the upper
stem (fig. 1).
• If the glow plug is already broken or the previous procedure
fails, drill and remove it.
N.B. During this procedure, all or part of the
electric connection could come out. In the first
case do not drill and carry out immediately the
tapping.
If the operation with the Torx socket does not succeed, use the
"roller" extractor (among the three supplied Ø2.5 - Ø3.5 - Ø4) to
remove the terminal part of the electrode of the spark plug (fig. 10).
