Possible causes and solutions:
1. The battery voltage is too low (capacity is reduced), manifested by slow speed and powerlessness when starting, charging or replacing;
< p >2. There is no fuel or too much fuel in the cylinder - check the engine fuel system;3. Spark plug has no spark or is weak - check ignition system; p>4. Air cannot enter the cylinder ---- check the air intake passage.
1. First check whether the engine oil and gasoline are newly added. Otherwise, they have been added for more than three months and the oil and gasoline need to be drained and replaced. Since engine oil and gasoline are only valid for three months, oil and gasoline used for more than three months have lost their viscosity and have no effect.
2. It is difficult for old generators to efuel to light up. The reason is that the spark plugs have carbon deposits. They either have to clean them or replace them with new ones. too dirty, resulting in lack of air. To clean or replace. If the engine oil has melted, because if the machine is not used for a long time, the engine oil should be drained, and if the gasoline is qualified and it has evaporated, resulting in purity insufficient. Difficulty igniting.
3. Check whether the starting method is correct, such as whether the oil switch is on, whether the shock absorber is closed when the cold engine starts for the first time, whether the starting method is correct, and whether the starting method is correct. startup has been achieved. Rotational speed, etc., then troubleshoot in the order of first checking the oil circuit, then checking the circuit, then checking the cylinder compression. First, turn on the crankcase oil drain switch, pullQuickly z the engine and identify the faulty area by observing the oil flow. If no or little oil flows from the oil switch, the mixture is not entering the cylinder or 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 the starting method is incorrect.
4. Remove the high voltage wire from the spark plug and test for fire: if there is no spark or the spark is very weak, it means there is a fault with the magneto or high voltage. thread ; If the spark is strong, it means there is a fault with the spark plug or the cylinder is leaking and the mixture is poorly compressed. Next, check or replace the spark plug. If it is confirmed that the spark plug is functioning normally, further check the conditiont of cylinder compression. Poor mixture compression in the cylinder may be due to a leak in the cylinder or a leak in the crankcase. The location of the leak can be detected through external inspection. If the air leak is caused by excessive mounting clearance (such as mounting clearance between the piston and the cylinder wall or various parts of the piston ring, etc.) or damage to the parts, the machine must be dismantled and inspected. For some magneto and multi-cylinder gasoline engines using battery ignition systems, after setting the stage gap and angle, it is necessary to check and adjust the ignition timing and correct the sequence ignition, because if the ignition sequence is disturbed, the machine will not be easy to start.
The German generator from Rennes XCMG will give you the answer
5 It is difficult to start a gasoline generator, and new machines require acertain break-in period, so the longer the generator. is used, the better. A qualified generator is not worn out, but worn out, so it is better to start the generator 1-2 times a month.
