There is a lot of relative motion components in engine, such as piston, piston ring,
cylinder, mutually meshing gear, etc., it’s very important to have a standard break-in
at the beginning of using. Break-in can help the moving parts adapt to each other,
correction work, form a smooth friction surface which can bear heavy load, by this
way the engine will have excellent performance and reliability.
Recommended break-in time is 20 hours, as follows:
0~10 hours: To avoid continuous operation under the condition of 1/2 throttle, the
speed should be changed frequently, and it is not recommended to operate for a long
time with a fixed throttle position; Cool the engine for 5 to 10 minutes after each hour
of operation. Avoid quick acceleration.
10~20 hours: To avoid continuous operation under the condition of 3/4 throttle, the
speed can be changed freely except full throttle.
Note:
During break-in period, do everyday maintaining, and eliminate hidden trouble in
time.
Break-in period ended, make a maintenance for the vehicle, then putted into
formal use.
