    • For Automatic Transmission Engines, please don't start is at reverse. For Semi-auto and Manual Transmission Engines, please do start at Neutral.
    • Check lubricating oil level and fuel level regularly. Make sure they are sufficient and not leaked.
    • Please do not accelerate until it has warmed up for 1-3 minutes if cooler start engine.
    • All new engines need a initial run-in time. Because the surface of the parts is not that smooth, they need a time to run-in to have the parts get smooth and work together better. The initial run-in should be at least 500KM. During the initial run-in, please avoid full-open throttle and don't start it over 80 percent of the top speed. Make sure to clear all fuel and change new when initial run-in over. Be strictly obey this will prolong the engine service life and has it working in good condition.
