SECTION 3. MAINTENANCE
3-6 Spark Plug
A spark plug of a wrong model or
wrong heat range may deteriorate the
engine’s performance or even damage the
engine.
If the engine is run continuously, the spark plug
and muffler will be very hot. Be careful not to touch
the muffler or spark plug.
Turn off generator, remove spark plug
maintenance cover ① and spark plug cap ②,and
insert the tool ④ through the hole from the
outside of the cover.
1)
Insert the handlebar ③ into the tool ④
and turn it counterclockwise to remove the
spark plug.
2)
Check the spark plug. Spark plug model:
E6TC/E6RTC
BPR7HS (NGK)
L87YC /R L87YC (CHAMPION)
W16FP / W16FPR (DENSO)
W6BC / WR6BC (BOSCH)
If the machine needs EMC Certification, engine
must use E6RTC spark plug
If the electrode is damaged, or insulation is
cracked or chipped, replace the spark plug. if it can
still be used, use a wire brush to remove carbon or
other deposits from the spark plug.
3) Measure the plug gap with a feeler gauge.
Correct as necessary by carefully bending the
side electrode. The gap should be 0.60-0.70
mm.
4) Check that the spark plug washer is in good
condition, and thread the spark plug in by hand
to prevent cross-threading.
5) After the spark plug seats on the washer,
tighten with a spark plug wrench to firmly press
on the washer.
If installing a new spark plug, tighten l/2 turn
after the spark plug has firmly pressed on the
washer. If reinstalling a used spark plug, tighten
l/8 - l/4 turn after the spark plug has firmly
pressed on the washer.
Spark Plug Torque: 20.0 N*m (2.0kgf*m,
14.8 lbf*ft)
The spark plug must be securely
tightened. An improperly tightened spark plug
could damage the engine.
Never use spark plugs which have an
improper heat range. Use only the recommended
spark plugs or equivalent.
