Spark plug
Disassembly the spark plug
Follow the steps below:
1. Pull out the spark plug high voltage wire.
2. Remove the spark plug with a spark plug wrench.
Use a hard wire or steel adhesion of carbon on the spark plug for removal of dirt, and then to use
with a feeler gauge to adjust the spark plug gap between 0.7~0.9mm.
When remove adherent carbon deposition, you need to observe the spark plug tip of the porcelain
two kinds of color at the same time. The color will tell you whether standard spark plug is fitted. The
ignition area of the normal spark plug used is light brown. If the insulator is burnt white and the
electrode is ablated, it is more appropriate to use a cold type spark plug.

Use the spark plug if the ambient temperature is too high and the
spark plug is overheating.

The incorrect installation of the spark plug will damage the engine. If the torgue of the spark plug is too large,
it will also do harm to the engine. If there is no torque wrench when installing or replacing a new spark plug,
screw it until there is resistance and then tighten it for 3/8 turn( 135
°
). If used the old spark plug, screw the spark
plug until there is resistance and then tighten 1/12 turn( 30
°
), However, the spark plug should be screwd to the
required torque as faras possible.
The unclean material will go through the spark plug and go into the engine to do harm to it. Therefore, when
we dismentle the spark plug, we have to use something to cover the installation hole of spark plug.
It is forbidden to use spark plugs below LDK8RTAIP.
