After starting it in cooling condition, you should increase the engine rotate speed gradually after 1-3 mins running,
and do not add the load while cooling.
As for totally new engine, its inner components like piston, piston rign need to be run in. It is very important to deal
with run-in correctly, if not, there’ll be more engine faults. The run-in procedure is as follows:
1. The engine should not be added too much load while new vehicle is in 0-500 km run-in period. The throttle
valve must not be completely open, avoiding to use the same gear for a long time, vehicle speed should not be more
than 30Km/h;
2. During 500-1000km run-in period, the engine should not be added too much load. The throttle valve should not
be completely open. Vehicle should run at 80% of each gear, and be shifted gear at any time, avoiding to use the
same gear for a long time, vehicle speed should not be more than 50Km/h;
3. New engine running in every 500Km should be maintained, the engine oil must be changed, the oil filter and oil
filter must be cleaned, valve clearance, clutch separation travel must be checked and adjusted.
Routine maintenance
：
1. After run-in period, generally speaking, the engine lubricating oil
should be replaced after 2000 km. It can be replaced in advance if the
oil quality changes.
2. Check the engine oil before driving everyday,If the oil level is below
the bottom line of the oil level window, you should make up the
lubricating oil to the oil window on the line.
3. Valve clearance inspection and adjustment: generally speaking, the
valve clearance has been adjusted properly when it’s delivered from the
factory. When the cylinder head has strange noise, you can adjust the
valve clearance to the rated value: 0.01mm
～
0.03mm.
4. Carburetor should be cleaned at regular intervals, and be delt with
necessary inspection and adjustment.
5. Air filter should be inspected and cleaned at regular intervals. First of
all, you should remove the filter element. If it is foam element, please
clean with gasoline, and dry it in the air, then add a little oil to the filter
and assemble. If it is paper element, just clean it with gasoline, dry it in
the air and assemble.
6. Check and adjust the fastening bolts regularly for looseness.
Foam element
Idle adjustment
1. Preheat the engine to operating temperature.
2. Tighten the idle screw firstly, then return 1.25 turns.
3. Adjust throttle stop screw to make the rotate speed to specified idle
speed. If the speed is too low, the engine is easy to stall.
4. Adjust the idle adjust screw slightly left and right, and fix it to the
location of engine’s hightest stable rotate speed.
5. Then readjust the throttle valve stop screw, to make the rotate speed
