  • Page 7: Battery Connection (Only For Electric-Start Type)

    BATTERY CONNECTION (electric-start type) In the case that the specifications of the batte4ry are 12V and more than 18A.h, connect its positive lead to the electromagnetic coil while connect its negative lead to engine mount strew, base screw or any place capable of grounding with the engine well.

  • Page 8: Control Connection Of Remote Distance (Option)

    ● Make sure not to connect the battery leads in reverse order, or short-circuit or breaker’s cutting may result. CONTROL CONNECTION OF REMOTE DISTANCE (OPTION) The holes in levers of both the choke and throttle are used for mounting optioned steel wires. The diagrams shown illustrate how to mount a solid steel wire and a meshed steel wire.

Single-core type Dismantle the air cleaner housing and check its filter element, Make sure it is clean and intact, otherwise clean or replace.
  • Page 13 Ⅲ. Dust-collecting type 1. Dismantle the dust-collecting hood and check the filter element of the air cleaner; make sure it is clean and intact, otherwise clean or replace. 2. Check whether there is any dust or dirt inside the dust- collecting hood, if any, clear away.
  • Page 14 FUEL AND FUEL TANK Fuel The engine must apply unleaded gasoline with an octane number over 86. Using unleaded gasoline will decrease the possibility of producing carbon deposit and will prolong the engine’s service life. Never apply used or polluted gasoline or a mixture of gasoline with engine oil. Make sure the fuel is free of dirt and water. Gasoline Containing Alcohol If you decide to use a gasoline containing alcohol (fuel blend), be sure its octane rating is at least as high as high as that recommended by the company.

  • Page 16: Starting The Engine

    STARTING THE ENGINE 1. Push the fuel cock to “ ON ”. 2. Push the choke lever to “ CLOSE ”. NOTE: if the engine is hot, closing the choke is unnecessary.
  • Page 17 3. Move left the throttle lever a little. 4. Start the engine as follows: a) Hand-operated kick-starter Push the engine switch to “ ON ”. Pull slightly the starting rope handle up until feeling anti-action, and then make a rapid pull. CAUTION: Releasing the handle suddenly may make it hitting the engine.

  • Page 19 ENGINE OIL ALARM The engine oil alarm is designed to function when the engine oil in the crankcase is insufficient. Lack of 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 “...

  • Page 20: Stop

    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, besides, too big mixture ratio will pollute the spark plug to result in starting the engine difficultly.
  • Page 21 2. Push the engine switch to “ OFF ”. 3. Set the fuel cock to “ OFF ”. CAUTION: Sudden stopping at high speed under heavy load is forbidden, otherwise damage will result.

  • Page 22: 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 23 3. Modifying Modifying the exhaust control system may make actual exhaust emissions exceeding statutory limit values. Illegal modification as such: a) Dismantle or modify any part of air intake or exhaust system. b) Modify or take off speed – adjusting connection device or speed adjustment device to result in the engines running beyond the set parameters.

For the sake of environmental protection, we suggest you take in discarded engine oil with a closed container and bring to local recycling station.
  • Page 27 CAUTION: Never run the engine without an air cleaner, or air with dirt and dust may enter the engine so speed the engine’s wear. Unscrew the wing nut, dismantle the air cleaner housing. Check if the two cores are damaged, if so, replace with new one. a) Foam filter element: clean with home detergents and warm water (or non-flammable or high flash-point cleansing solvents) and dry up, then soak in clean engine oil until saturated.
  • Page 28 a) Foam filter element: clean with home detergents and warm water (or non-flammable or high flash-point cleansing solvents ) and dry up, then soak in clean engine oil until saturated. Squeeze out excess oil, otherwise, the engine will discharge smoke in starting stage. b) Paper filter element: knock the core against a solid plane to got rid of accumulated dust or blow out dust from inside to outside with high-pressure air flow (not more than 30psi).
  • Page 29 Oil bath type 1. Remove the nut and air cleaner housing, and take out the filter element. 2. Clean with home detergents (or high flash-point cleansing solvents) and warm water, and dry up. 3. Soak in clean engine oil until saturated. Squeeze excess oil, or the engine will discharge smoke in starting stage.
