Maintenance notice
This section introduces the inspection and replacement method of engine lubricating oil as well as the cleaning method of
lubricating oil strainer and lubricating oil filter. It also introduces various lubricating positions of the complete vehicle of this model.
As an important factor that influences the engine’s performance and life span, the lubricating oil must be selected as per
regulations; ordinary engine oil, gear oil, vegetable oil, etc. are not allowed to be used instead of it. This engine was filled with
gasoline engine oil of 10W/40EG grade when leaving factory for sale. If you want to use other lubricating oil, its quality scale must
reach Grade SG, and its viscosity shall be selected according to the accompanying diagram depending upon region and air
temperature changes. While replacing lubricating oil, fully discharge the original lubricating oil in the crankcase and clean it up
with washing kerosene, and then refill fresh lubricating oil as per regulations.
The lubricating oil inside the engine must be fully discharged before inspection and cleaning.
Technical specifications: Lubricating oil charge volume: 1.8L
Oil pump flow rate: 10L/min (when engine speed is at 4000 rpm).
Tightening torque of oil drain plug:28-32N.m
WARNING:
Repeatedly contacting the engine lubricating oil for a long period may cause skin cancer. Although such possibility is
small when you deal with used engines oil every day, Care must be taken to fully cleanse your hands with soap
and water after dealing with the used engine oil. Children are strictly prohibited from getting near to it
。

Troubleshooting
Lubricating Position of Complete Vehicle
Among the positions shown in the above diagram, besides applying dedicated lubricating oil for chain
to the
driving chain, apply lithium base grease to all other positions.
All lubricating oils not specified for use in this manual shall be ordinary common lubricating oil.
All sliding surfaces and cables not shown in this diagram shall be coated with lubricating oil or lubricating grease.
Lubrication of Control Lines
Regular lubrication shall be carried out to the clutch control line, throttle control line and steering cable. To do this, remove the
upper joining parts of all control lines, sufficiently lubricate and maintain their hoisting cables and all points of support with lithium
base grease.
●Lubricating oil contaminated
1. Fail to replace lubricating oil according to the
maintenance period table;
2. The pouring orifice thread is damaged thus causing
poor seal;
3. The piston ring is worn.
●Lubricating oil pressure low
1. The oil level is too low;
2. Oil through, orifice port or oil strainer is clogged;
3. Oil pumps failure.
●Lubricating oil consumes too fast
1. There is leakage with the engine;
2. The piston ring is worn.
3. The inlet/exhaust valve guide is worn;
4. The oil shield is worn or damaged.

Refilling method: Remove the oil filler plug, refill the engine oil slowly with a funnel until the oil level in the engine oil dipstick
reaches the upper-middle limit. Then insert the oil filter plug and screw it up.
Replacement of lubricating oil
While replacing lubricating oil, it shall be carried out before the engine has cooled down. This will ensure quick and complete
discharge of the engine oil inside the crankcase.
When replacing, unscrew the oil drain plug and discharge the waste engine oil, and then clean the oil drain plug, engine oil
strainer, engine oil filter, etc. Finally, insert the oil drain plug. Unscrew the oil filter plug and slowly refill 1.8L new engine oil of the
