instrument to measure the distance between the

of the external electrodes. If the spark plug electrode is
rusty, damaged, or the insulator is broken, the spark
plug must be replaced.
NOTE

ENGINE LUBRICANT SYSTEM
LUBRICANT SELECTION
Lubricating oil is an important factor affecting the
performance and life of the engine. It must be selected
according to regulations. It is forbidden to replace it
with ordinary engine oil, gear oil, vegetable oil, etc.
When the car leaves the factory, 15W/40-SF grade
gasoline is filled in the transmission box. If you change
to other lubricating oil, its quality level should reach
SG level or above, and the viscosity should be selected
according to the attached drawings according to
different regions and temperature changes. When
replacing the lubricating oil, please drain the original
lubricating oil in the crankcase and clean it with
washing kerosene before adding new lubricating oil
according to the regulations.
LUBRICANT INSPECTION
Dipstick
If the engine is running, turn off the engine and wait a
few minutes for the oil to reach the bottom of the
crankcase. Place the engine vertically on the ground
and observe through the oil observation window. The
oil level should be between the upper and lower scales
of the observation window.
If the oil level is higher than the upper graduation line,
the excess oil should be discharged.
If the oil level is lower than the lower mark, you
should add lubricating oil.
LUBRICANT REPLACEMENT
When replacing the lubricating oil, it should be done before the engine is warm and has not yet
cooled, so as to ensure that the lubricating oil in the crankcase can be discharged quickly and
completely. The replacement steps are as follows.
1. When replacing, place an oil pan under the engine and unscrew the oil bolt A to release the
lubricating oil.
2. Check the plug gasket for damage, and replace it with a new one if it is damaged.
3. When the lubricating oil is completely discharged, install and tighten the oil drain bolt and
