The correct use of spray duster
First, spray duster operation points 1. Check the engine. Check that the components of the gasoline engine are installed correctly and securely. Check the flashover of the spark plug (blue is normal, and run continuously without interruption). Check the engine compression ratio (usually turn the starter wheel by hand as the piston approaches top dead center. When there is a certain pressure, the crankshaft can automatically turn over an angle very quickly when crossing TDC. It can be used only after the engine has been checked. 2. Add fuel to the tank. The spray duster uses a single-cylinder two-stroke gasoline engine that burns a mixture of gasoline and engine oil. No. 90 for gasoline, blended oil for motor oil and engine oil, and a mixture ratio of gasoline and engine oil of 20:1. Mixing oil should be shaken uniformly, and it should be stopped for a while. When the dirt is a little heavy, it can be poured into the fuel tank. 3. Adjust the choke. The choke handle is “off†outwards and “inside†to the inside. In cold days or the first time, it is turned off by about 2/3. When the heat engine is started, the choke valve is in the fully open position. 4. Turn on the throttle switch. The vertical direction of the handle means "open", 90 turns is closed, and do not use too much force when turning. 5. Wrap the starter rope in the direction of the right rotation around the starter wheel, pull the oil mist into the cylinder several times, and then pull the starter rope smoothly and quickly. Generally, the good gasoline engine can be started 2 or 3 times. 6. Immediately after the start, the choke valve is fully opened, and the throttle lever handle is adjusted at the same time so that the gasoline engine runs at a low speed for 3 to 5 minutes, so that the machine temperature rises and operates normally. 7. Add liquid to the tank. Before adding the liquid, spray with clean water for 1 time to check for leaks. Do not add liquid medicine too quickly, too full, so as not to spill the liquid from the air outlet of the filter net into the fan housing; the liquid medicine must be clean to avoid nozzle clogging; after adding the liquid, the medicine tank cover must be tightly capped. 8. Put the machine on the back, the operator adjusts the hand throttle switch to stabilize the gasoline engine at 5000 rev/min, then open the handle to switch the liquid, and then swing the nozzle with his right hand to spray while walking. 9. When the operation is stopped, close the chemical liquid switch to reduce the fuel supply. After the gasoline engine runs at a low speed for 3 to 5 minutes, close the throttle switch. Wait for the gasoline engine to stop and then lower the machine. Second, the use of spray duster precautions 1. Before starting the new machine or the sealed machine, the engine oil sealed in the cylinder block should be excluded. That is, the spark plug should be removed, the spark plug hole should be slightly blocked with the thumb of the left hand, and then the starter rope should be used several times to eject the excess oil. Spray duster structure as shown below. 2. When spraying, do not spray in one place to avoid injury. At the same time, the forward speed and the speed of the swing nozzle should be properly matched to prevent leakage and affect the quality of the work. 3. Because the spray mist particles are very fine, it is not easy to observe the spraying conditions. Therefore, under normal circumstances, the crop leaves will be sprayed as long as they are blown by the nozzle, and there is no need for re-spraying. 4. When the natural wind exceeds grade 3, it cannot be sprayed. Because of the large loss of wind and heavy pesticides, the effect is poor and unsafe. In particular, it is not suitable for top wind operation. 5. The operator must wear a mask, wear long-sleeved clothes and trousers, and take off clothes after work. 1 person working hours should not be too long, there should be 2 to 3 people rotation jobs. 6. When working, do not smoke or eat food. Bring towels, soap, or goggles. Wash your face and skin. 7. When you find that you have headaches, nausea, vomiting and other symptoms of poisoning, stop the operation immediately and seek medical advice. 8. This machine uses gasoline as fuel and should be fireproofed during use.
