SAFETY PRECAUTIONS ! WARNING △ Before operating the engine, be sure to read and familiar with the manual carefully, otherwise injury to personnel or damage to equipment may occur. Please pay special attention to the following: 1. Running the engine in a well-ventilated place, keep it at least one meter away from building walls or other equipments; keep away from inflammables such as gasoline, matches and so on to avoid possibility of fire. 2.
PARTS DESCRIPTION 6
PRE-OPERATE INSPECTION Ⅰ.ENGINE OIL CAUTION ● Engine oil is a key factor in deciding the engine’s performance. Do not apply engine oil with additives or 2-stroke gasoline oil, as they haven’t enough lubrication, which may shorten the engine’s service life. ● Check the engine with it stopped on a level ground. Engine oil recommended: SAE10W-30。 As viscosity varies with regions and temperatures, so the Lubricant has to be selected in accordance with our recommendation. (Pic.1) (Pic.1) Inspect step: 1.
4. Reinstall the dipstick. CAUTION Run with insufficient engine oil may damage the engine severely. Ⅱ. OIL IN THE REDUCTION GEAR BOX (only for the model equipped with it) 1/2 Reduction gearbox with an auto-centrifugal clutch. 1. Remove the dipstick and clean it. (Pic. 3. Pic.4) 2. Reinsert the dipstick without screwing it in, and then take out it and check oil level. 3. If the oil level is too low, and recommended engine oil until it arrives the upper level mark.
Ⅲ. AIR CLENANER(Pic. 5) CAUTION Never run the engine without an air cleaner, or severe wear of the engine may occur. (Pic. 5) Dismantle the air cleaner housing and check its filter element, make sure it is clean and intact, otherwise clean or replace it. Ⅳ. FUEL 1. Gasoline is extremely flammable and may explosive under certain conditions. 2. Refueling in a well – ventilation area with the engine stopped.
4.Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry enough before starting the engine. 5. Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children. Fuel tank capacity: (173F-B/177F-B:5.5 liters); (182F-B/188F-B/190F-B: 6.0liters) The engine must apply unleaded gasoline with an octane number over 86.
STARTING OF THE ENGINE 1.Push the fuel switch to “ON”. (Pic.6) 2.Push the chock lever to “OFF”. (Pic.7) (Pic.6) (Pic.7) NOTE If the engine is hot, closing the choke is unnecessary. 3.Move left the throttle lever a little. (Pic.8) (Pic.
4.Start the engine a). Rope handle Starter. Push the engine switch to “ON”. (Pic. 9) then make a rapid pull. (Pic. 10) (Pic. 9) Pull slightly the starting rope handle up until feeling anti-action, and (Electric) (Pic. 10) CAUTION Releasing the handle suddenly may make it hitting the engine. Release the handle slowly conforming to its recoiling force. 2) Electric starter Push the engine switch to “START” and remain there until the engine Start. (Pic. 11) (Pic.
CAUTION Use the engine switch not more than 5 second each time to avoid damage of the engine. Try once more 10 second later after last attempt failures. Once the engine starts, reset the engine switch to “ON”. OPERATION 1. Preheat the engine and push back the choke lever to “ON”.(Pic.12) 2. Set the throttle lever in proper position to ensure the engine runs at required velocity.(Pic.13) (Pic .12) (Pic .
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”. CAUTION If the engine still fails to work, check the engine oil level first before go to other check items.
The green indicator would be light once the circuit off. If this happen, 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. This problem can be solved as follows: replace the main jet of carburetor with a smaller one, then, adjust the idly screw.
STOP In an emergency, push the engine switch to “OFF” to stall the engine. Stop it in normal in the following sequence: 1. Push right the throttle valve lever to the bottom (Pic. 15) 3. Set the fuel switch to “OFF” (Pic. 15). 2. Push the engine switch to “OFF” (Pic. 16) (Electric) (Pic. 17) (Pic. 17) 16 (Pic.
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.
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. 5.Ignition is too advanced. Once you find any of above problems, contact your dealer for help.
MAINTENANCE I.
NOTES 1) More often than that in the schedule if in dusty circumstances. 2) The items should be done by your dealer you are specially trained and is well equipped with tools. : Only for inside-ventilating double-core carburetors. : Only for paper core air cleaners. Ⅱ. METHOD 1. Replacement of Engine Oil A still hot engine is helpful to drain out the engine oil in the crankcase rapidly and entirely. (Pic. 18) 1) Turn off the oil filler cap and drain plug to drain engine oil thoroughly.
NOTE Do not dump oil containers or discarded engine oil into rubbish boxes or onto the ground. For the sake of environmental protection, we suggest you take in discarded engine oil with a closed container and bring to local recycling station. 2.Service of Air Cleaner A dirty air cleaner may block enough air’s flowing into the carburetor. To keep the carburetor in Good working conditions, please service the air cleaner periodically.
4)Empty the oil in the air cleaner, Use non-flammable or high flash-point cleaning solvents to clean the dusty, and then dry-up the air cleaner box. 5)install the air cleaner filter and cover to original position. ! WARNING △ Gasoline is extremely flammable and explosive in certain conditions. Keep cigarette, sparks and open flames away. After reinstalling the deposit cup, check it for leakage and make sure the area around the engine is dry enough. 4.
2) Clean the spark plug with a steel brush. If the insulator is damaged, replace the spark plug instead. 3) Measure the spark plug clearance with a feeler. The clearance should be 0.7～0.8mm,If adjustment is necessary, bend the side electrode carefully. (Pic. 20) 4) Check if the spark plug gasket is in good conditions, or replace with a new one. 5) Screw on the spark plug to the bottom first by hand and then tighten it up by a spark plug wrench. (Pic.
5. Spark Eliminator (Option) (Pic. 22) The spark eliminator should be serviced at least once every 100 hour’s operation so as to keep it in a sound condition. ! WARNING △ The muffler is very hot during running the engine and even a long Time after stopping. Never touch it, or you may get burns. Service After the engine cools down. (Pic. 22) a) Unscrew two nuts M4, and remove the exhaust elbow from the engine body. b) Turn off five screws M5 from the muffler guard and take out the latter.
b) Obtain standard idling by adjusting the throttle fixing screw under the engine runs at a low speed. (Pic. 24) Standard idling: 1500±150rpm (Pic. 24) (Pic.
TRANSPORT, STORAGE AND REMOVAL FROM STORAGE I.TRANSPORT Transport with the fuel switch turned off. Transport or store the engine it is cool so as to avoid getting burns or fire. If the engine is not kept in use for a long time, be sure to store it properly. 1) Make sure the storage area is dry and free of dust. 2) Make sure to put the oil (which in the gasoline tank and carburetor) into another proper container. CURTION Fuel is extremely flammable and explosive under certain conditions.
TROUBLESHOOTING Ⅰ. STARTING ENGINE DIFFICULTLY TROUBLE 1. Something wrong with the fuel system 2. Fuel supply is blocked or on fuel.

! WARNING △ When testing the spark plug, never hold the high- voltage wire of the spark plug with wet hand. Make sure there is no spilled fuel outside the engine and that the spark plug isn’t dipped with fuel. To prevent fire, keep sparks for away from the spark plug mount hole. Once you find any of above problems, contact the authorization entitle to the dealer of the privilege helps for you. TROUBLE 1.
