MODEL)
1. #1 SPARK PLUG
1) After setting spark plug in spark plug socket, connect
the spark plug socket, extension and Universal Joint to
each other.
2) Screw spark plug into cylinder head using the con-
nected tools above mentioned. At this point, it is necessary
to support the rear end of the tools with fingertips.
3) When spark plug is screwed in two or three turns, tem-
porarily disconnect the tools connected in step 1) above.
4) Confirm that spark plug is screwed into the cylinder
head properly by touching it with finger. If it is difficult to
reach it by hand, confirm its condition by using mirror and
suchlike.
5) Cover ABS pipes with rag to prevent damage.
