I: Safety Precautions There is a possibility of voiding the warranty and personal or equipment damage if instructions are not followed. Please pay special attention to the following: 1. Operate the engine according to the recommendations in your owner's manual. Do not overload, overrun the engine or run it with low load and at low speed for a long period of time. 2. Use regulated 87 octane brand of gas. The fuel should be fully deposited and filtrated before use.

III: Pre-Operation Inspection 1. ENGINE OIL Use 4-stroke engine oil, API service classification SE class or equivalent. Check the API service label on the oil container to be sure it includes the letters SE class or equivalent. SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range. SAE Viscosity Grades Oil level check Check method: 1. Remove the dipstick and clean it with a rag. 2.
3. FUEL RECOMMENDATION 1. Remove the fuel tank cap and check the fuel level. 2. If the level is too low, refuel the tank to the recommended level. Remember to never add fuel over the fuel filler shoulder. Gasoline is extremely flammable and is explosive under certain conditions. Only add fuel in a well-ventilation area with the engine stopped. Do not smoke and do not allow flames or sparks in the area where gasoline is stored or where the fuel tank is refueled.
IV. Starting the Engine 1. Turn the fuel Shutoff to the “ON” (OPEN) position. Fuel Shutoff ON OFF 2. Turn the choke lever to the “CLOSE” (CHOKE) position. If the gasoline engine is hot, don’t close the choke. Choke Lever Close (Choke) 3. Move throttle lever to the left a little. Throttle Lever Low Speed High Speed 4. Start the engine a. Turn the engine switch to the “ON” (START) position. b. Pull the starter grip lightly until resistance is felt, then pull briskly.
V. Running the Engine Choke Lever 1. Preheat the engine and push back the choke lever to the “OPEN” position. OPEN Throttle Lever 2. Move the throttle lever to proper position to make the gasoline engine run at required speed. High Altitude Kit for EPAIII Engines 3000ft to 6000ft or 6000ft to 8000ft of elevation At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease and fuel consumption will increase.
VI. Stopping the Engine In an emergency, push the engine switch to the “OFF” position. In normal non emergency conditions, please do as follows: 1. Push the throttle lever to the right to the low speed position. Throttle Lever 2. Push the engine switch to the “OFF” position. 3. Set the fuel shutoff to “OFF” position. Fuel Shutoff OFF Never stop the engine at high speed under heavy load unless there is an emergency because engine could be damaged. CONTACT US AT www.DRpower.
VII. Exhaust Control System With the engine running, carbon monoxide, nitrogen oxide and hydrocarbons are produced, and in certain conditions, nitrogen oxide and hydrocarbon will react chemically with each other to make smoke while carbon monoxide is toxic, so proper maintenance to control these dangers is very important. To keep the exhaust of your engine within the standard exhaust emission, pay attention to the following: 1.
VIII: Maintenance The engine must be properly maintained to ensure safe operation, economy and trouble-free, as well as eco-friendly. In order to keep your gasoline engine in good working condition, it must be periodically serviced. The following maintenance schedule and routine inspection procedures must be carefully followed.
2. MAINTENANCE METHOD 1) Replacement of engine oil (see “Oil Level Check” in Chapter IV to check oil level) The oil will drain more rapidly and completely when the engine is warm. (1) Remove the oil filler cap and drain plug to drain engine oil thoroughly. (2) Reinstall the drain plug and screw in securely. (3) Fill with the specified engine oil up to the upper level mark. Do not dump oil containers or discarded engine oil into rubbish boxes or onto the ground.
(2) Clear away dirt from around the spark plug base. (3) Only remove the spark plug with a spark plug wrench. (4) Visually check the spark plug. Clean with a steel brush. If the insulator is damaged, replace the spark plug. (5) Measure the spark plug clearance with a feeler gage. The clearance should be 0.7~0.8mm. If adjustment is necessary, bend the side electrode carefully. (6) Check if the spark plug gasket is in good conditions. Screw in the spark plug as far as you can by hand to prevent thread damage.
IX. Transport and Storage Transport with the fuel shutoff turned to the “OFF” position. Transport or store the engine when it is cool to avoid getting burns or causing fire. Do not excessively tilt the engine because fuel will spill. Spilled fuel or fuel vapor may ignite to cause fire. Fuel is extremely flammable and explosive under certain conditions. Keep smoke, fire and spark away from operating site. If the engine is not kept in use for a long period of time, be sure to store it properly. 1.
X: Troubleshooting 1. ENGINE STARTING DIFFICULTLY: Something wrong with the fuel system. Normal high – tension line Fuel supply is not smooth or Normal highFuel supply is no fuel supply. tension line spark normal. High-tension line not normal Normal spark plug Normal fuel supply system. Normal cylinder compression Normal spark plug spark TROUBLE CAUSE REMEDY There is not enough fuel in fuel tank and fuel shutoff Fill fuel, open fuel shutoff. is closed.
When testing the spark plug, never hold the high- voltage wire of the spark plug with a 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 far away from the spark plug mounting hole. 2.
4. ENGINE SUDDENLY STOPS RUNNING: CAUSE REMEDY Fuel tank is empty Refill fuel tank Carburetor is clogged Check fuel line and dredge Float is leaking Repair Needle valve is sticking Dismantle float chamber and free up needle valve Spark plug is damaged, or short- circuited by carbon Replace spark plug deposit Engine Ignition system internal Stops suddenly when running.
