    Ⅲ. AIR CLENANER(Pic. 5) CAUTION Never run the engine without an air cleaner, or severe wear of the engine may occur. Dismantle the air cleaner housing and check its filter element, make sure it is clean and intact, otherwise clean or replace it. (Pic.
  • Page 11 5. Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children. Fuel tank capacity: 3.6liters The engine must apply unleaded gasoline with an octane number over 86.Using unleaded gasoline will decrease the possibility of producing carbon deposit and prolong the engine’s service life. Never apply used or polluted gasoline or a mixture of gasoline and engine oil.

  • Page 15: Engine Oil Alarm

     Engine Oil Alarm The engine oil alarm is designed to alarm the user the fact that the engine oil in the crankcase in insufficient. Run with insufficient engine oil may damage the engine. Once oil level in the crankcase is too low, the engine oil alarm will stall the engine automatically to make it free of damage while the engine switch is still at “ON”.

  • Page 16: Operating On Highlands

    The green indicator would be light once the circuit off. If this happens, please find out the reason and solve it then press the button to recover the breaker.  Operating on Highlands On highlands, the standard mixture ratio is relatively too big so the engine performance may be impaired while the fuel consumption may increase.

  • Page 17: Stop

    STOP In an emergency, push the engine switch to “OFF” to stall the engine. Stop it in normal in the following sequence: 2. Push the engine switch to “OFF” 1. Push right the throttle valve lever to the bottom (Pic. 15). (Pic.

  • Page 18: Exhaust Control System

    EXHAUST CONTROL SYSTEM With the engine running, carbon monoxide, oxide of nitrogen and hydrocarbon will produce, and in certain conditions, oxide of nitrogen and hydrocarbon will react chemically each other to make smoke while carbon monoxide is toxic, so exhaust control of them is very important. The company decreases the exhaust emissions by introducing poor-fuel carburetors and other devices into the engine to solve the problem.
  • Page 19 2.Modify or take off speed-adjusting connection device or speed adjustment device to result in the engine’s running or outside the set parameters. Ⅳ.PROBLEMS AFFECTING EXHAUST EMISSIOS 1. Difficult starting or difficult stopping. 2.Unstable idling. 3.Give off black smoke or consume too much fuel. 4.Poor ignition sparks or sparks returned.
