Assembly Note: The wind pipe and flexible pipe connection should be tightly secured with metal clamps, and the three blowing pipes should be rotated into position. Fuel and Oil 1. 2 stroke blowers: Use a mixture of gasoline and oil, with a volume mixing ratio of 25:1. Gasoline grade: 93. Oil grade: Special oil for 2-stroke gasoline engines, FB grade or higher. Note: Pure gasoline is strictly prohibited as fuel. Starting: 1. Before starting, thoroughly inspect the blower to ensure it is in a safe state. The blower must be at least 3 meters away from the refueling point. Ensure there are no onlookers or other animals in the vicinity. Push the stop switch to the start position. 2. Cold engine start: Press the oiler on the carburetor until oil flows out of the transparent plastic tube. Close the throttle door, lightly pull the starter 4-6 times, then pull the starter rope to start the engine. After the engine starts, slowly place the throttle door in the fully open position. 3. Hot engine start: In hot engine conditions, place the throttle handle in the full open position. Lightly pull the starter 2-3 times to allow the engine to suck in fuel, then quickly pull the starter. Operation: There should be no onlookers or other animals within 15 meters of the operator. 2. Adjust the throttle control switch to the highest position, grip the handle, and swing back and forth to sweep. Shutdown: 1. Release the throttle control handle to run the engine at low speed for at least 30 seconds. 2. Push the stop switch to the shutdown (STOP) position, and the engine will stop running. Safety Regulations: 1. Requirements for the operator's physical condition: The operator must be in good physical and mental condition. 2. Requirements for operator: Must wear work clothes; must wear labor protective gloves, safety helmets, protective goggles, and earplugs, and wear labor shoes. Blower Maintenance: 1. Daily maintenance: (shift maintenance) (1) Clean the oil and dust on the surface of the gasoline engine. (2) Remove the air filter and clean the foam filter with gasoline. Dust off the paper filter element. (3) Check if the oil pipe joints leak, if the seals are leaking, and if the compression is normal. (4) Check external fastening screws of the gasoline engine. (5) After maintenance, store it in a dry, cool place, cover it with plastic cloth to prevent dirt and moisture, and prevent starting difficulties due to humidity and heat. 2. 50 hour maintenance (cumulative operating time of the gasoline engine): (1) Complete daily maintenance. (2) Clean the fuel tank. (3) Remove carbon deposits from the spark plug and adjust the gap to (0.6-0.7) mm. (4) Clean the carbon deposits in the muffler. (5) Remove the air deflector and clean the dust and mud between the air deflector and the cylinder cooling fins. 3. 100 hour maintenance (cumulative operating time of the gasoline engine): (1) Complete 50-hour maintenance. (2) Disassemble and clean the entire carburetor. (3) Disassemble the cylinder body and piston rings, clean the exhaust holes of the cylinder body, piston tops, piston ring grooves, and spark plug carbon deposits. (4) Remove the housing and clean the interior of the housing from oil stains and dirt. (5) Clean the interior of the crankcase. Rotate the crankshaft continuously during the cleaning process to clean the main and connecting rod bearings. (6) Check the ignition system. (7) Check if the oil seals leak. (8) Check the cylinder compression status. 4. 500 hour maintenance (cumulative operating time of the gasoline engine): Disassemble the entire machine (except for the crankshaft and connecting rod) for cleaning and inspection, and check the wear of vulnerable parts for repair and replacement according to the specific situation. Long Term Storage: 1. Drain the fuel from the fuel tank. 2. Burn off the fuel in the carburetor. 3. Clean the air filter and reassemble it. 4. Remove the spark plug, inject a few drops of oil into the combustion chamber, pull the starter a few times to stop the piston near the top dead center. 5. Clean each part and replace damaged parts in time. 6. Store the blower in a ventilated and dry warehouse. Air Filter: 1. Close the throttle valve (cold start position). This prevents dirt from entering the carburetor throat when the air filter is removed. Brush off dirt accumulated in the air purifier area. 2. R
