Spark Plug - DAELIM NS 125 DLX Owner's Manual

SPARK PLUG

If electrode is stained or clearance is not
right, satisfactory spark is not produced.
Clean and make adjustment.
Remove spark plug cap.
Clean around the plug.
Using a plug wrench, remove plug.
Clean plug with plug cleaner.
Check electrode for wear and corro-
sion.
Measure clearance using a feeler gauge.
PLUG GAP: 0.8-0.9mm
Tighten with hands until the plug
washer touches cylinder head.
STANDARD PLUG: CR8EH-9
If new plug is installed, turn 1/2 and
tighten using a plug wrench.
If plug is reused, turn 1/3~1/4 and tighten.
CAUTION
If plug of different maker or different
heat value is used, it causes
unsatisfactory engine starting,
inadequate engine revolution and
output deterioration.
The spark plug must be securely
tightened. An improperly tightened
plug can become very hot and
possibly damage the engine.
<DEALING WITH POOR STARTING>
When the starter doesn't work during
driving in winter times or in a repeated
short distance, use the suitable spark plug
for this driving condition.
Poor starting may happen when nonstop
driving in low speed, even though we
produce standard plug.
In case starter isn't working well in driving
repeatedly in a short distance or in an area
with many traffic signals, use the CR7EH-
9 pulg instead of standard plug CR8EH-9
