At present, all local spring agricultural production has been fully implemented. When using agricultural machinery, the following 10 kinds of erroneous operations should be avoided:
1. Remove the wrong practice when driving. After a locomotive or transplanter emerges, people stop or work in front of the car. Once the locomotive or rice transplanter finishes driving, it will suddenly cause injury and cause an accident.
2. Wrong operation when disassembling the spring. Disassembly and assembly of clutch springs, valve lock clamps, etc., without using special tools, but picking up with a screwdriver, etc., will cause springs to spring up and strike people.
3. Incorrect operation when refueling. When refueling at night, use an open flame instead of a safety light, battery light, or lighting; on the side of the exhaust pipe when refueling; do not wipe the oil droplets out of the box; do not dry on the clothes to dry fire or smoke; Instead of covering with water, do not cover with sand, dry earth, canvas, sacks, etc. after ignition; add lead with petrol suction pipe, or touch the mouth with oil parts, causing poisoning.
4. Inflatable tires are not safe to operate. After the tires are unloaded, they are re-inflated and the steel rims will pop up without injury. The correct method is to lock the tire, lock ring, collar and rim together with a chain before inflating, and to inflate the side of the collar toward the ground or wall.
5. Maintain the wrong operation of the conveyor. Move the hand or other object to the transmission part; the belt joint is not firmly installed; the belt is belted during the operation of the machine; the belt is pulled by hand; the machine does not turn off when the belt tightness is adjusted; and it crosses over the belt.
6. The wrong way to add water. When the engine is hot, especially in the open condition, open the water tank cover immediately, instead of turning on the water release switch first. After the water pressure is reduced, cover the water tank cover with a towel, etc., and place the body on the back and tilt the head to one side. Unscrew it slowly.
7. Commission the wrong operation of the engine. When debugging the machine, personnel approach dangerous parts such as fans, transmission belts, or exhaust pipes; or place tools and parts on the machine to cause injury and damage; try to stop the machine during commissioning; turn off the machine in the lower part of the machine; A person should be assigned to guard the operating mechanism to prevent outsiders from moving; before commissioning, it is necessary to check the tools and parts and send a signal.
8. Hand crank the wrong operation. When the serviceman cranks the engine by hand, separate the grip from the other four fingers with his thumb instead of holding the handle with his fingers together; lower the handle instead of lifting the handle; hold the handle and shake it with both hands.
9. The wrong way to support the vehicle. When the tire is damaged or replaced, it is not safe to use bricks, stones, wooden blocks or a jack to support it. This is not safe. The correct approach should be to use a jack and a solid wooden pier to lift the frame at the same time. The wheel is also stuck with triangle wood or larger stones to prevent the vehicle from moving back and forth.
10. The wrong way to start with the start rope. When starting with the starter rope, the starter rope pulls the rope around the hand, or starts the rope around the flywheel for more than 1.5 turns; when the hand rotates the flywheel, it is constantly oiled, de-energized and turned too fast, thereby causing an explosion, rebound and injury to the fingers.
