1. First check whether the engine oil and gasoline are newly added. If they are not newly added and are more than three months old, you need to drain the engine oil and gasoline and replace them with new ones because the engine is damaged. oil and gasoline are only valid for three months, engine oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. The old gasoline generator is having trouble turning on. We need to check the spark plug for carbon deposits. If so, it must be cleaned or replaced with a new one. Then check if the air filter is too dirty, causing a lack of air. If so, it also needs to be cleaned or replaced. We also need to check if the engine oil has melted, because if the machine is not used for a long time, the engine oil needs to be changed. Finally, we also need to check if the essence is qualified and if it has evaporated. , resulting in insufficient purity and difficulty in inflammation.
3. Check whether the starting method is correct, check whether the oil switch can be turned on, whether the air door is closed when the cold engine starts for the first time and whether the starting speed is reached, etc. First, turn on the crankcase oil drain switch, quickly fire the engine, and check the oil flow to determine the extent of the fault. If no oil comes out of the oil switch or little oil comes out, the mixture is not entering. the cylinder or the mixture is too thin. If there is a lot of oil leaking from the oil switch, the mixture is too rich. The reason may be that there is a problem with the oil supply system, or it may be that the starting method is incorrect and needs to be restarted.
4. Remove the high voltage wire fromthe spark plug and test the fire. If there is no spark or the spark is very weak, the magneto or high voltage wire is defective. the spark is strong, it means the spark plug is defective or the cylinder is leaking and the mixture is poor. Confirm whether the spark plug can work normally, if not, it should be replaced in time.
5. It is difficult to start a gasoline generator. New machines require a certain break-in period. A qualified generator is not worn out, but damaged, so it is better to start the generator once a month. .-2 times.
Gasoline generator cannot start
1. First check if the engine oil and gasoline have been added recently. Otherwise, they have been added more than three months ago. engine oil and gasoline must be drained and replaced again. Engine oil and gasoline are only valid for three months. The hOil and gasoline used for more than three months have lost their viscosity and are useless.
2. Check if the engine oil and generator gasoline are filled. Otherwise, the generator will not turn on or start.
3. If the above conditions are met, check whether the spark plug ignites. Otherwise, remove the spark plug and put gasoline on it before reinstalling it to see if the generator fires. , it would be good if it started with the ignition.
Detailed information
Before each use of a gasoline generator, the following checks should be carried out to ensure safe and normal use of the generator: < p>1. If the generator is not used for a long time (more than a month), the starter battery will lose power due to self-discharge. Please use an external charger to charge the battery.
2. Check if there is enoughgasoline in the fuel tank.
3. Check the oil switch and oil pipeline for oil leaks.elephant.
4. Check whether the battery starting voltage is higher than 12V and observe whether the battery appearance is damaged or leaking.
5. Observe the quality of the engine oil to determine if it needs to be replaced.
6. Check if the engine oil level is between the oil dipstick grids.

What to do if the spark plug of 700W gasoline generator does not light
First check if the engine oil and gasoline are newly added, if not new, they have been added more than three months ago, so the oil and gasoline should be drained and replaced. Engine oil and gasoline are only valid for three months. Oil and gasoline used for more than three months have lost their viscosityand are useless.
Check if the engine oil and gasoline in the generator are filled. Otherwise, the generator will not be able to turn on and start.
If the above is achieved, check to see if the spark plug ignites. Otherwise, remove the spark plug, dip some gasoline in it and install it to see if the generator ignites. ignition and starting.

The use of a gasoline generator should Note:
1) Theory guides practice. Only by thoroughly mastering the basic principles and basic structure of small gasoline engines can we carry out fault analysis and treatment, especially for different types of oil engines, specific model analysis specific is required;
2) When an error occurs. Only by carrying out comprehensive and scientific analysis and judgment based on the scene that we can guarantee that the fault is handled accurately, and we cannot handle the problem based on imagination or so-called past experience. Gasoline engines often have oil lines, circuits and other parts that fail at the same time, resulting in more complex failure phenomena. Sometimes similar phenomena occur at different fault points, causing certain troubleshooting difficulties.
By connecting and analyzing fault phenomena observed on site, imagining different possible causes of the fault and analyzing and comparing them, the extent and location of the fault can be determined. Then from simple to complex, from the outside to the inside, first analyze the circuit then the oil circuit, then calibrate the ignition time, check the gas distribution order, and compress the fault until 'at a certain point
3) Develop from bonnes habits, carry out necessary inspections before starting the machine and carry out regular inspections during the operation of the machine to try to avoid sudden breakdowns
4) Strictly carry out technical maintenance; all levels on the oil machine to ensure that the oil The engine is in good working condition to avoid sudden breakdowns and major accidents

< /p>In In addition to spark plugs, breakdowns occur. The highest rate is the combined coil which generates electricity in the high voltage coil motor. Inspection Steps: 1. Remove the spark plug and cover it with a high voltage cap. Touch the spark plug to the metal shell of the engine and start the machine to check the performance of the spark plug. 2. Check high voltage! coil and trigger coilmotor. First use a multimeter to measure the impedance, then start the machine to measure the voltage. The high voltage coil output line is red and black, and the trigger coil output line is blue and white. multimeter, you can use the instantaneous short circuit method. Normally there are sparks from the short circuit! 3. Check the output voltage of the yellow and black igniter wires. You can also use the instantaneous short circuit method. Normally there are sparks caused by a short circuit. Check the igniter, disconnect the black and white wires, and check the spark plug for spark. The black and white wires are the wires from the dead light switch to the power door lock. When the electric door lock leaks, the igniter does not come out. high voltage. 4. The input wire of the high voltage box is the yellow and black wire. If there is tensionin the yellow and black wires, remove the high voltage cap and check for sparks in the high voltage wire. the normal distance between the high voltage wire and the motor shell is 0.5-0.2cm. Sparks appear when starting the machine.
