Just buying a new portable power station is not enough. You must be able to handle it. Do you still have warranty? In fact, in most cases, you don't need it at all. You yourself can find out why the equipment does not work, and repair the gas generator with your own hands. Here are some tips and tricks for repairing your portable power supply.
Self troubleshooting and repair
Have you heard the term Troubleshooting? Translated from English, this means troubleshooting. These are simple steps to take when you encounter a problem. For example, a consistent check of the main components of the gas generator, which could become unusable.
Fuel system repair
First of all, you need to check fuel system. Here are some of the most common problems, which you can fix yourself:
Low-quality fuel is very often the reason for stopping the gas generator;
Check for gasoline in the fuel tank. Often, power plants are equipped with a special sensor to measure the fuel level. But often it quickly falls into disrepair. Therefore, find a stick and shove it into the tank to the end. Keep dirt out of the fuel tank. From it you can determine how much fuel is left;
After you have made sure that there is enough gasoline in the system, then turn off the fuel supply valve, unscrew the tube from the carburetor through which gasoline is supplied and drain all the fuel into the tank by opening the valve. Gasoline should begin to pour into the container, otherwise the nozzles could become clogged. You need to clean them up.
Dead battery
Also, the gas generator may not work due to discharged batteries.
Overload
Sometimes it happens that the power plant can be overloaded with consumers and devices, the sum of the powers of which exceeds the rated power of the generator. Try running the generator completely off load, or just disconnect a few appliances from it.
Clogged carburetor
Check the carburetor of the gas generator for blockage.
Clogged gasoline injection needle.
If the needle is clogged, it must be cleaned. Blow it out using Automobile compressor. Apply nozzle.

Blockage or sticking of the float mechanism for supplying fuel to the gasoline unit.
Purchase a carburetor cleaner and process the entire structure. Wait a few minutes, and then move the float mechanism with your own hands and purge the valve.
Valve repair
The valves of a gasoline engine are controlled by a timing belt. To check its operation, remove the block cover by unscrewing a few bolts. You will see several valves and a pushrod. You need to push the shaft in the right direction. If you see that everything is moving, but the valves are not moving, then they are stuck. To repair them, take a carburetor cleaner and a hammer. Rotate the rocker arm and tap the valves carefully with a hammer. Further, turning the shaft, push the valves back, pouring plenty of liquid over them. Repeat this action until the valves come off.
The generator works but does not provide power.
If the gas generator starts, but does not produce energy, then the engine is most likely damaged, or the internal settings of the generator are knocked down. Take a voltmeter and an ammeter and compare the readings at the power plant with the readings indicated in the instructions. If the readings diverge, then this is certainly an internal breakdown and your unit needs professional expertise and repair. So call the experts.
Emergency start of the power plant with a drill and a battery
If your portable generator starts but does not produce voltage, you can:

About maintenance of gasoline generators
Maintenance of gasoline generators is not much different from maintenance of their diesel counterparts. The differences are due design features diesel and gasoline engines and the difference in the duration of their working resources. For gasoline engines, it is less, therefore, maintenance of gas generators should be carried out more often. As in the case of diesel generators, the maintenance of gasoline generators is individual in nature, carried out in accordance with the manufacturer's regulations and adjusted to real operating conditions (working intensity, fuel quality and Supplies, climatic conditions, dust level).
So what does it consist of?
Despite the equipping of modern gas generators with emergency automatics, before each start, a visual inspection unit and control operations such as checking fuel, oil and coolant levels. If necessary, they must be topped up or replaced. Now about the scheduled maintenance of gas generators. Usually the first scheduled Maintenance gasoline generator is carried out after 50 hours of operation, and subsequent - with an interval of 50-100 hours. During the scheduled maintenance of the gas generator, numerous checks are performed and preventive actions, namely: the level of fuel, oil and coolant, integrity and tightness are checked fuel tank and fuel lines, operation of protective systems, vibration level, condition of the spark plug, power and control cables, reliability electrical contacts and bolted connections, insulation resistance of alternator windings, electrical components of the engine management system, starter, electrolyte level and density, static Charger; topping up or replacing technical fluids, cleaning or replacing the air and fuel filter, broaching bolted connections, replacing spark plugs, adjusting valves, adjusting and flushing the carburetor, cleaning the generator from dust and dirt. The last operation is carried out especially carefully for the alternator cooling fins and as often as possible in case of increased dustiness, for example, when the generator is operated outdoors. MOT ends with testing the gas generator for Idling and under load with checking the shaft speed, output voltage, automatic operation in manual and automatic modes. During long downtimes, it is recommended to start the gasoline generator at least once a month for an hour at 75% load.
Who can service generators? In short, pre-launch maintenance - any user with sufficient experience and skill, scheduled maintenance - only qualified specialists who have undergone special training.
The gas generator is technical device providing autonomous power generation. Like any equipment, the generator needs timely maintenance. So manufacturers of power equipment recommend every 100 moto hours to perform: cleaning or replacing air filter, oil change, valve adjustment, engine speed adjustment, external cleaning of dirt. Timely work performed will significantly extend the life of your unit. Maintenance of the gas generator can be done by hand, if available necessary tools and minimal knowledge. What you need to know when servicing gas generators:
1. Replacing or cleaning the generator air filter. Open the air filter housing and remove the filter, inspect it. If the integrity is intact and the filter is slightly dusty, blow it with strong air pressure. For these purposes, a compressor is well suited. Also remove dirt from the inside of the filter housing. Everything must be perfectly clean, otherwise sand and dust enter the combustion chamber and lead to wear of the central piston group (CPG).
2. Changing the oil in the generator engine. To replace, it is necessary to drain the old oil by unscrewing the bolt drain hole. It is better to change the oil on a warm engine, i.e. the engine must be run before draining the old oil. Thus, the oil becomes more liquid. For more efficient draining, tilt the generator towards the drain hole. After the oil is drained, it is advisable to flush the engine with gasoline or special flushing oil.
After all operations, it is necessary to fill in fresh oil according to the level provided by the manufacturer.
3. Gasoline valve adjustment. The essence of valve adjustment is to set certain gaps between the valve disc and the rocker arm. Valve adjustment is carried out with special probes and is determined by the manufacturer. In other words, engines different capacities and manufacturers have certain sizes. Neglect of adjustments leads to the bending of the pusher rods and the destruction of the valve system. We recommend an adjustment every 100 hours of engine operation.

4. Engine speed control. The engine speed is adjusted with a tachometer ( measuring device, designed to measure rotational speed [number of revolutions per unit time]). The engine speed directly affects the frequency electric current generated by the generator. 3000 revolutions is directly proportional to 50 hertz, which is the norm for Russian electrical networks. If the engine speed is too high, you run the risk of burning the devices plugged into the gas generator socket.
5. Washing the gas generator. External cleaning from dirt should be carried out from time to time, especially if the generator is used at a construction site or other environment that is hostile to machinery. Washing the generator will clean the unit of sand, dust and dirt, as well as remove oil smudges and help locate leaks. Which in turn will help determine if the replacement of oil seals or gaskets is required. Washing is best done with gasoline under pressure, using a compressor with a special nozzle.
