Lubricating oil is an important factor affecting engine
performance and life. It must be selected according to the
regulations. It is forbidden to replace with ordinary engine oil,
gear oil and vegetable oil.
When the car leaves the factory, the transmission box is filled
with 15W/40-SF grade oil. If other lubricating oil is used, its
quality grade should reach SG or above, and the viscosity
should be selected according to different regions and
temperature
changes,
according
to
the
attached
drawings. When changing the lubricating oil, please run out the
original lubricating oil in the crankcase, clean it with washing
kerosene, and then add new lubricating oil according to the
regulations.
Lubricating oil inspection
Oil level gauge
If the engine is running, turn off and wait a few minutes for the
oil to reach the bottom of the crankcase. Remove the oil gauge
and observe through the oil gauge that the oil level should be
between the upper and lower scales of the oil gauge.
If the oil level is higher than the upper scale, excess oil should
be discharged.
If the oil level is below the lower scale, lubricating oil should
be added.
Lubricating oil replacement
When changing the lubricating oil, it should be carried out before the engine is warm and not yet cooled, so as to
ensure that the lubricating oil in the crankcase can be quickly and completely discharged. When replacing, place
an oil pan under the engine, and open the oil bolt A to discharge the oil. Check the plug gasket for breakage and
replace it with a new one if it is. When the lubricating oil is completely discharged, install the oil discharge bolt
and gasket and tighten them. Tightening torque: 15 ~ 20N·m refill new lubricating oil and check the oil position.

Notes
◆
The camshaft is lubricated by the oil passage of the cylinder, and the oil passage can not have foreign
matter entering. The camshaft bearing rotates lexibly and without clamping. The pressure reducing valve
swing block rotates lexibly and can return to the normal position, otherwise it is easy to cause engine
damage;
◆
Before installing the cylinder, the cylinder positioning pin must be assembled;
◆
When assembling, the cylinder camshaft hole, must apply the right amount of lubricating oil.
