How to start a gasoline generator. Step-by-step instructions for operating a gasoline generator How to start a gasoline generator

First of all, carefully read the operating instructions. Studying it will help you find answers to many questions regarding a specific model.

After purchasing and transporting the device, it is important to check it for damage. correct connection pipelines.

Buy enough oil and gasoline. They are often transported in cans, so you should carefully ensure that there are no foreign impurities in the fuel. The use of alcohol-based octane-boosting additives is not permitted.

The unit must be placed on a flat and dry surface. If you purchased a gas generator without an exhaust system exhaust gases, then it can only be used outdoors. The unit must be grounded and all energy consumers must be disconnected before starting.

Starting and stopping the machine

How to use gasoline generator when turned on? Starting the unit must be done as follows: after opening the rotary valve, you need to pull the throttle lever towards you. If an electric starter is provided, then you need to press the Start button until the engine starts.

If the engine is started using manual control, then you need to go to the Start position and then pull the handle towards you. You should let the generator work for a few minutes simply, and only then connect consumers.

The generator is turned off as follows: first, all consumers are disconnected and the load of the unit is disconnected. The engine needs to run on its own again for a few minutes, and then press the Start/On/Off button and wait until it stops running. The rotary fuel valve is closed at the end of use of the unit.

When asked how to use a gasoline generator, the instructions will tell you in more detail. The machine does not require constant supervision at all: most of the models presented in our online store are equipped with special oil and fuel level sensors. Among them are the Akita R3000, Hitachi E42SB, Akita R3000D and many others. When the liquid level drops, the unit automatically stops operating.

When running the engine for the first time, it is recommended to use only 50% load for one and a half hours. It is also advisable to carry out the rollback when the gas generator is rarely used in order to avoid the accumulation of moisture inside the engine and reduce oxidation processes in electrical contacts.

Long-term work with minimal or no load is unacceptable.

If you use the unit in hot weather, you should ensure a flow of fresh air.

The oil needs to be changed every 50 hours of operation, and under heavy load or used in hot weather - every 25 hours.

If there is a lot of dust around, then it is necessary to service the foam rubber or paper filter every 10-15 hours and change it if necessary.

Has its own characteristics. When working with them, you must follow certain rules that guarantee their long-term and, most importantly, safe operation.

Depending on the power and purpose, the gas generator can be equipped with several types of starting:

• Manual with cord- used in low-power models. For example, HYUNDAI HHY960A. In order for the unit to start working, pull the cord handle all the way and then sharply pull it to the side. The starter handle must be held until the cord returns to its original position.
• Electric start is carried out from the battery in medium and high power devices. For example, HYUNDAI HY3100LE. The unit operates after turning on the button on the control panel or turning the ignition key.
• Autorun - additional option(not intended for devices with manual start). It monitors the state of the supply network in the event of a power failure in the main network and stops when it is restored.
• Allowed start from remote control (remote control). For example, HYUNDAI HY7000LER. It allows you to control the basic parameters of the network, as well as remotely control the station’s operating modes, start and stop the device.

What should you do before starting the gas generator?

* First of all, by implementing starting the gas generator, remember about safety precautions. You should not smoke near the unit and do not start work if you spill gasoline, etc. on the unit while refueling. You can start a gasoline generator only in a well-ventilated area. During prolonged operation, any unit becomes hot, and to avoid burns, do not touch the heated parts.

* You should check the grounding of the gas generator before starting it. Make sure there is enough fuel in the tank; if not, add it. This is strictly prohibited when the engine is running.

*If you do not use technology long time, it is necessary to drain the fuel from the tank, clean the unit body and lubricate the main working components. When resuming operation, replace the fuel in the tank. Also clean the spark plug, carburetor and fuel valve, and remove grease from the body.

* It is necessary to constantly monitor the engine oil level. By detecting its decline in a timely manner, you can prevent rapid wear and premature engine failure. It is recommended to change the oil every 50-70 hours of operation. You should not mix synthetic and mineral grades; this will have a bad effect on the internal condition of engine parts.

* After making the first start, turn off the engine after a few seconds and only then restart the gas generator. The motor must be allowed to warm up, only after this can the load on the device itself be gradually increased. To avoid damage, monitor the current consumption. It should not exceed what is produced.

* Before starting the device, make sure that there are no electrical consumers connected to it.

* If any problems occur during operation, we recommend that you immediately contact specialists who specialize in this profile.

Here are instructions for starting a gasoline generator for the first time using the example of a 6 kW SKAT generator. Let's start the generator step by step and you see how easy it is.

1. Unpack the generator and make sure there is no damage.

2. Remove tools and accessories, usually located under the fuel tank.

3. Check the package contents.

4. Make sure there is nothing extra left inside.

6. Prepare the battery for use.

Models of SKAT generators containing the letter E in the marking equipped with electric starters. They require a battery to operate. Since 2014, a gel battery has been supplied, ready for use immediately.

7. Place the battery on the pad, connect power wires to the terminals, observing polarity.

8. Fill the oil sump with engine oil.

Note. For generators, oil marked SAE 10W-30 is recommended. Read more about oil for gasoline generators in the article “Choosing engine oil for a gasoline generator”

9. Unscrew the dipstick plug.

Note. On the device sticker or in the instruction manual check the oil sump volume.

10. Measure required amount oil, fill and screw the dipstick plug into place.

IMPORTANT! It is necessary to check the oil level on the dipstick before each use.

11. Make sure that the ignition is turned off and, using a manual start, rotate the crankshaft several times - this is necessary to distribute the oil over the rubbing surfaces of the engine.

12. Fill the fuel tank.

IMPORTANT! Gasoline loses its properties after 2 months. If you haven't used the generator this whole time, you'll have to replace the fuel in the tank.

13. Open the fuel valve.

The generator is ready to start!

Manual generator start

1. Move the air damper to the “closed” position.
2. Ignition – to the “ON” position.
3. Pull the starter handle until the first resistance is noticeable, return it to its place and start the generator with a more energetic movement.
4. Move the air damper to the “open” position.

Warm up generator set A couple of minutes.

Starting with electric starter

1. Make sure the fuel valve is open.
2. Move the air damper to the “Closed” position.
3. Ignition to the “ON” position, press and hold until it starts.
4. Move the air damper to the “Open” position.

Warm up the generator for a few minutes.

Connecting electrical appliances to the generator

1. Set the circuit breaker to the "OFF" position.
2. Plug the plug into the outlet.
3. Turn on the circuit breaker.
4. Turn on the device itself.

Turn off in reverse order: device - breaker - socket.

Stopping the generator

The generator should idle for 2-3 minutes. Then turn off the fuel tap and turn off the ignition.

SKAT generators are easy to start even in the cold season. You can verify this by looking

The figures below show the control panel and the main parts of a four-stroke gasoline generator that you have to deal with during its operation and maintenance.

Gas generator device: 1 - fuel level sensor, 2 - fuel tank, 3 - fuse, 4 - 12V power button, 5 - 12V socket, 6 - voltmeter, 7 - 220V socket, 8 - control light, 9 - ground terminal, 10 - engine switch, 11 - cover/dipstick for filling and oil control, 12 - oil drain plug.

Gasoline generator structure: 13 - frame, 14 - cover fuel tank, 15 - manual starter handle, 16 - fuel valve, 17 - air filter, 18 - protective screen muffler.

The first 20 hours (the figure may be different) of the gas generator’s operation is the time during which the parts get used to each other. Therefore, during this period, you cannot connect a load whose power exceeds 50% of the rated power of the unit.

If you plan to always run the gas generator at an altitude of more than 1500 meters above sea level, you should check with your dealer before purchasing whether it is possible to properly upgrade the carburetor. In high altitude areas, the air/fuel mixture of a standard carburetor will be very rich. Performance will decrease and fuel consumption will increase. To avoid this, install a smaller diameter main fuel jet in the carburetor and adjust the engine accordingly. Even with a modified carburetor, engine power will decrease approximately 3.5% for every 300 m of elevation gain. The effect of altitude on engine power will be greater if the carburetor is not modified. Running the engine at altitudes lower than those specified for the modified carburetor may result in reduced power, overheating, and severe engine damage.

Checking the oil level. Checking the oil level in the engine crankcase is carried out before each start, since high-quality engine lubrication is extremely important. an important condition correct operation gas generator.

Checking the oil level in the crankcase is performed with the engine not running. The generator is installed on a level horizontal surface. If the generator was running before, wait about 5 minutes after stopping.

The oil level is checked using a dipstick inserted into the oil filler neck. Before removing it, you need to clean the area around it to prevent contamination from entering the crankcase. The dipstick is removed and wiped with a clean cloth. It is installed (without screwing) into the oil filler neck until it stops and removed again. The oil mark should be located between the mark on the dipstick and its end. The figure below shows the process of measuring the oil level.

If there is not enough oil in the crankcase, you need to add it to bottom edge neck holes and install the dipstick in place, screwing it tightly.

Refueling. Refueling must be done in a well-ventilated area. When working, smoking and using open flames are prohibited. You need to work carefully, avoiding spills. Inhalation of vapors and skin contact with fuel should be avoided whenever possible.

Gasoline generators usually use A92 gasoline (at least). But in any case, you need to use the brand of gasoline that is indicated in the operating instructions for the generator. Do not use leaded or lightly leaded gasoline.

The fuel consumption of a gas generator depends on its power and can range from values ​​less than 1 l/hour (with a power of 2 kW or less) to 2 (with a power of 5 kW) or more l/hour.

If the engine is four-stroke, pure gasoline is used for refueling without mixing it with oil. Two-stroke engines use a mixture of gasoline and motor oil as fuel (for two-stroke engines) in the ratio specified in the instructions.

As for the adjustment of the gas generator carburetor and the engine speed controller, they are usually carried out at the manufacturer. The voltage and frequency at the generator output depend on the engine rotation speed. Tampering with carburetor settings will usually void the warranty.

If gasoline is already poured into the tank, you need to check its level - using the fuel level indicator or visually. The maximum level should be located no higher than the shoulder of the fuel filter (see figure below).

If there is no fuel in the tank at all or there is not enough fuel, you need to add gasoline to the shoulder of the fuel filter - approximately 20-25 mm below the upper edge of the filler neck. To avoid fuel leakage due to thermal expansion, do not fill the tank to the top of the neck. After finishing refueling, you need to replace the fuel tank cap and screw it tightly.

You should not make large (for a year) reserves of gasoline; six months after production, tarring reactions appear in gasoline. After this period, the use of gasoline risks excess carbon deposits and smoke.

The rate of chemical changes during gasoline storage depends on temperature, contact of non-ferrous metals with gasoline, degree of filling of the container, amount of transfusion, etc. Storage temperature has the greatest accelerating effect. An increase in the temperature of gasoline during storage is accompanied by accelerated oxidation and tar formation. When the storage temperature increases by 10°, the rate of resin formation increases by 2.4-2.8 times. All the most commonly used metals, when in contact with gasoline, accelerate its oxidation and the formation of tarry substances. On the other hand, the walls of metal canisters are impermeable to oxygen, unlike the walls of plastic canisters. Copper and its alloys have the greatest accelerating effect. Repeated transfers of gasoline from container to container contribute to a decrease in the quality of gasoline. When transfused, gasoline is saturated with atmospheric oxygen, the intensity of oxidative processes in it increases, and tar formation accelerates. The process of oxidation and tarring is significantly accelerated in the presence of resinous substances previously deposited in the container or residues of tarred gasoline from previous storage. When gasoline turns reddish, it is sure sign that the resin content exceeds the permissible limit. If the container is not tightly closed, low-boiling components evaporate. The evaporation of light hydrocarbons leads to an increase in the density of gasoline and a deterioration in their starting qualities. In gasolines obtained from direct distillation and thermal cracking products, low-boiling fractions have the highest anti-knock properties, therefore, when they are lost, the octane numbers of such gasolines decrease slightly.

Engine starting. The gas generator can be started using a manual or electric starter. There are generator models equipped with both types of starting.

Starting the generator with a manual starter is carried out as follows.

• Disconnect electricity consumers from the electric generator, set the voltage switch (fuse) to the “off” position.

• The fuel valve opens.

• The choke handle is set to the "closed" position. This action is performed on a cold engine and is not performed if the engine has previously been running and remains warm.

• The ignition is turned on (the engine switch is turned to the “on” position).

• The starter handle is pulled out until resistance appears, released to the lower position and jerked sharply, or immediately jerked sharply without releasing to the lower position. In this case, the cord is not pulled out completely and is not released sharply from the upper position in order to avoid damage to the starter.

• After the engine has warmed up (1-3 minutes), the air damper is set to the “open” position. It's better to do it gradually as it warms up.

Starting with an electric starter can vary greatly depending on the degree of automation of the process. In the very simple version, when starting with an electric starter, the same actions are first performed as with a manual start (the tap opens, the air damper closes on a cold engine, the ignition is turned on).

The engine switch is set to the "electric start" position. After starting the engine, you must return the switch to previous position. On some models of gas generators this happens automatically.

If the engine does not start immediately, the time the switch is in the “electric start” position should not exceed 5 seconds. Restart should be made no earlier than after 10 seconds. If three attempts to start the engine fail, you should look for a malfunction due to which the engine does not start. The battery may need to be charged.

After starting the engine, open the choke.

It is prohibited to operate the generator without connecting the load for more than 3-30 minutes (the figure is very different for different gas generators). The minimum load on a gasoline generator is about 10-20% of the rated power of the generator. The fact is that if you do not load the gas generator, the fuel may not burn completely. In 70% similar cases Plaque is deposited in the combustion chamber and on the spark plugs. Therefore, it is recommended to periodically carry out preventive maintenance - run the unit for an hour, connecting to it consumers with a total energy consumption equal to the rated power of the generator. This helps get rid of deposits and associated soot, as well as maintain engine life.

Load switching procedure. A certain order must be followed. Consumers with the highest inrush currents need to be connected first. Then connect the devices in descending order of the last. Finally, energy consumers with a starting current coefficient equal to 1 are connected, for example, electric heaters.

Stopping the engine. The operation is performed in the following sequence.

• Electrical consumers are turned off.
• The voltage switch (fuse) is turned off.
• If the generator was operating under heavy load, let the generator run for several minutes (1-3 minutes) without load.
• The ignition is turned off.
• The fuel valve closes.

At emergency stop generator, you must immediately turn off the ignition.

Maintenance

Typical types of maintenance work and their approximate frequency are presented in the table below.

Approximate maintenance schedule for gasoline generators*

* - The table contains approximate data; the exact data should be found in the operating manual for a specific gas generator. For example, an oil change is often required after 6 months or 100 hours, rather than 50.
** - the first oil change is performed after 20-25 hours. Sometimes the instructions require the first oil change after 8 hours, then the second change after 25 hours.

In addition to the above work, it is necessary to perform others related to engine disassembly, but they are performed in service centers.

The chart shown only applies to normal conditions operation of the gas generator. If the engine is operated in extreme conditions(long-term increased loads, high temperatures, high humidity and dust), the time between maintenance must be reduced.

For gasoline generators, it is necessary to use only high-quality oils for gasoline engines. If we are talking about a four-stroke engine, then SAE 10W30 can be used as a universal oil for operation at any temperature (if the generator is started very rarely). It should be borne in mind that at temperatures above 4°C, multi-temperature oils are consumed to a greater extent than conventional ones and can cause accelerated engine wear. When using them, it is necessary to check the oil level more often than usual.

The optimal choice of oils for different temperatures can be made using the following information. The most recommended oils depending on operating temperature:

• above 4 °C - SAE 30;
• from -18 °C to +4 °C - SAE 10W-30, 5W-30;
• below 4 °C - synthetic oils SAE 5W-20, 5W-30.

When using SAE 30 oil at temperatures below 4°C, starting may be difficult due to lack of lubrication and the use of this oil at low temperatures, can lead to premature wear engine.

Avoid long-term contact of the skin of your hands with oil (machine oil is carcinogenic). Always wash your hands thoroughly with soap.

The oil must be changed when the engine is warm (1-3 minutes), this ensures quick and complete drainage of the waste. To replace, you need to unscrew the plug with the oil level indicator (dipstick) (1), unscrew the drain plug (2) and drain the oil into a suitable container. After this, screw in the drain plug and fill in fresh oil through the dipstick hole (1) to the required level.

Air filter maintenance. The air filter cleans the air that enters the carburetor, where it mixes with fuel. During operation of the gas generator, the filter gradually becomes dirty and ceases to perform its functions. A clogged air filter reduces quality fuel mixture, disrupts engine operation and leads to accelerated wear.

To prevent this from happening, the air filter must be serviced regularly. This is done as follows.

• Remove the filter housing cover.
• Remove and inspect the filter for dirt and damage.
• Damaged paper and foam filters are replaced with new ones. A dirty paper filter element must also be replaced. The contaminated foam filter is washed with soapy water, wrung out thoroughly, and dried. Cleaning the foam filter element with gasoline is not recommended due to the fire hazard of the latter.
• The foam filter is moistened with clean motor or special oil, wrung out and inserted into place. Do not allow the skin of your hands to come into contact with the oil.
• Close the filter housing cover.

Cleaning the fuel filter. Before entering the combustion chamber, the fuel passes through several filters. One of them is located in the fuel tap. It needs to be washed from time to time. To do this you need:

• close the fuel valve;
• unscrew the sump nut and remove the o-ring and strainer;
• wash the sedimentation tank, filter and sealing ring in gasoline;
• install the parts in place and tighten the sump nut;
• Open the fuel valve and check for fuel leaks.

Fuel tap with filter: 1 - fuel tap, 2 - settling filter, 3 - mesh, 4 - o-ring, 5 - settling tank.

Spark plug maintenance. For gasoline generators, only those spark plugs specified by the manufacturer should be used. Information about this is contained in the operating manuals for the equipment. Maintenance of the spark plug is carried out only on a cold engine. The work is performed in the following sequence:

• The spark plug cap can be removed and cleaned if necessary.
• Using a spark plug wrench, unscrew the spark plug.
• The integrity of its insulator is visually checked. If cracks are detected, the spark plug must be replaced.
• A special probe measures the gap between the electrodes, which should normally be 0.7-0.8 mm. If the actual values ​​deviate from the required ones, the spark plug gap is adjusted by bending or bending the upper electrode, or replacing the spark plug.
• If necessary, carbon deposits can be removed with fine sandpaper or a file.
• The candle is installed in place manually to avoid thread distortion.
• Wraps with a force of NO MORE than 25-30 Nm. After twisting new spark plug ignition by hand, it should be tightened 1/2 turn with a wrench to compress the washer. If installing an already used spark plug, it should be tightened by turning only 1/8-1/4 turn after tightening by hand.
• The cap is put on.

Preparing a gas generator for long-term storage (preservation)

• Completely drain the gasoline from the tank and dry it through the drain screw through the carburetor. With the drain screw loosened, remove the spark plug cap and pull the starter cord 3-4 times to drain the fuel from the fuel pump. Clean the fuel filters and install them in place.
• Change the engine oil.
• Unscrew the spark plug and pour one tablespoon into the cylinder motor oil. Rotate the engine shaft several times so that the oil covers the rubbing surfaces. If the cylinder has been coated with oil during storage preparation, the engine may smoke slightly during startup. This is fine.
• Screw the spark plug into place and turn the shaft with the starter handle until resistance appears. At this moment, the piston is at the top of the compression stroke, the intake and exhaust valves are closed, which prevents internal corrosion of the engine.
• Place the generator in a clean and dry place for long-term storage.

As mentioned above, gasoline oxidizes and deteriorates during storage. Old fuel causes poor starting; it contains resinous substances that contaminate the fuel system and can cause engine failure. How long fuel can be stored in the fuel tank and carburetor without causing functional problems can vary depending on factors such as temperature, air humidity, and how full the fuel tank is. Air in a partially filled fuel tank causes fuel to deteriorate. High temperature and wet air accelerate the aging of gasoline. The problem of fuel quality deterioration may occur within 2-3 months or less, so it is recommended that during long breaks in operation, drain the fuel from the tank and carburetor and always use fresh fuel for operation.

Possible malfunctions of the gas generator and methods for eliminating them

Safety

You must not be allowed to be present in work area strangers and animals.

Avoid using the generator in areas with high humidity, on open space during snow or rain. When working with the unit, hands and clothing must be dry.

Do not use the electric generator near flammable materials, flammable and explosive gases and liquids. The generator should be located at least 1 meter from other equipment and walls. You must be careful not to touch the engine or exhaust pipe while the gas generator is running. This can cause serious burns.

Smoking is prohibited near the generator, and open flames or sparks must not be allowed near it.

Handle power cables with care; do not touch live parts of the generator. Damaged wires must be insulated or replaced immediately.

Before repairing and servicing the gas generator, it is recommended to disconnect the spark plug wire to avoid accidental starting of the engine.

A generator with a remote start is turned on by a remote control, which basically has the form of a key fob with an antenna, which makes it possible to control the device at a certain distance. The principle is almost identical to car alarm. The motor starts after pressing the button located on the key fob. Disabling occurs in the same way.

Of the advantages remote start generator can be noted:

Ease and simplicity of device control(the remote control range is several tens of meters, you don’t need to get up or leave the house in bad weather to start your generator).
Multifunctional remote control has several buttons, when pressed, it is possible to configure the operation of the generator, depending on changes in air temperature, as well as the operation of the power plant according to a preliminary schedule.

There are not so many disadvantages of remotely starting a generator, but they also occur:

The key fob (remote control) works at a distance of only a few tens of meters, and this is not always enough for users.

The characteristics of possible types of generator starting are listed, and the choice, of course, is yours. When choosing, take into account the physical capabilities of your roommates, because you may not always be in right time V in the right place. If you are planning to buy a generator for business, then carefully calculate: is it not better to pay more and know for sure that production will not be idle, and freezers and refrigerators will not leak, since when the electricity in the network is turned off, they will instantly receive high-quality current from the generator with automation.
