A mobile generator, in terms of operating principles, works exactly the same as a fixed generator. They produce electrical energy by transforming fossil fuel energy into electrical energy through an internal combustion engine.
Unlike fixed generators, the great advantage of a mobile generator is that it can be transported to meet energy requirements wherever it is needed. They are widely used by emergency services to power disaster rescue and relief operations, the construction industry, and military response units. Mobile generators are also used by other end users that require temporary off-grid mobile power, for special events, at holiday homes that are located off the electricity grid, parties, concerts, summer camps, and many other uses. They are also commonly rented out to be used for all these purposes.
Recommendations for the maintenance of a mobile generator
As with any mechanical device, proper portable generator maintenance is essential if you want to avoid device failure when you need it most. Make sure your portable generator is ready to run when you need it most with the following basic maintenance tips:
1. Turn on your mobile generator periodically.
Running your mobile generator on a regular basis will keep the device working properly and prevent the starting battery from running down. This will allow your mobile generator to be in optimal condition when you need it most.
2. In case of prolonged periods of inactivity of the mobile generator, check the fuel.
Don’t make the mistake of leaving old gasoline in the generator’s fuel tank. To prevent fuel from breaking down, add a fuel stabilizer to the tank or drain any remaining fuel if you plan on long-term storage.
3. Check your fuel lines on your mobile generator.
With time and use, the fuel lines on your mobile generator can crack, tear, or become clogged. This can prevent the fuel supply from reaching the system and prevent your generator from starting or running efficiently.
If you detect a clogged or leaking line, replace it with a new one. They are readily available on the market and sold in many sizes. They are often quite cheap.
4. Periodic oil and oil filter changes according to the manufacturer’s recommendations.
Prevent your generator oil from degrading, change it regularly along with the oil filter. Refer to the device’s user manual to learn the manufacturer’s recommendations for correct preventive maintenance.
5. Periodically replace the air and fuel filters.
Most experts say that if an air or fuel filter looks dirty, it is time to replace it with a new one. This is solid advice as they can really wear out with time and use. If a filter breaks or gets damaged, this could spell bad news for your generator. Refer to the device’s user manual to be informed of the manufacturer’s recommendations for correct preventive maintenance.
6. Check the spark plugs of the mobile generator periodically.
Faulty spark plugs are a relatively common reason mobile generators won’t start. Either the plug associated with the spark plug is dirty, compromising its connection, or it could be in its last stretch of life and cause problems to start. Either way, if the plug doesn’t arc electricity, your mobile generator may have trouble starting.
Make sure your mobile generator engine has completely cooled down before removing any plugs and inspecting them. If they look dirty, clean it with a wire brush and insert it back into your generator with a torque wrench. When doing this yourself, be careful not to over-twist and strip the spark plug threads, which could compromise its connection or even crack its porcelain insulator and cause damage to the generator engine. If the plug looks fine on the outside, but still isn’t working, try swapping it out for a new one and see if that helps.
Even if your mobile generator isn’t having problems and you’re just doing a routine checkup or preventative maintenance, it might be time to replace the plug. As a general rule of thumb, if your air filter is dirty enough to need cleaning or replacement, it’s time to replace the spark plugs as well.
7. Invest in a long, sturdy extension cord.
It’s no secret, mobile generators are loud! To reduce noise, most temporary installations locate the mobile generator away from the load it is powering. But as an extension cord increases in length or decreases in gauge, the amount of voltage it can carry decreases. This could mean your generator is working harder to put out less power and your unit is wearing out unnecessarily over time. If you place your mobile generator some distance away, be sure to use heavy-duty wire of the gauge recommended by the manufacturer of the device.
Safety Recommendations for using a mobile generator.
Below we discuss dangers associated with improper use of mobile generators, and the specific risks inherent in the use of mobile generators. We also provide useful information to ensure that workers and others who use such equipment remain safe.
1. Shocks and electrocution from the improper use of power or accidentally energizing other electrical systems.
The electricity created by mobile generators can be just as dangerous as electricity from the public power grid.
It also has some additional dangers because mobile generator users often bypass safety devices (such as circuit breakers) that are built into electrical systems. Here are some tips to avoid electrocution:
- Never connect a mobile generator directly to the electrical system of a structure (hospital, home, office, etc.) unless a qualified electrician has properly installed the generator with a transfer switch recommended by the manufacturer. Connecting a mobile generator directly to the electrical system of any civil structure without the proper use of an installed transfer switch can energize the electrical network wiring over long distances. This creates an electrocution hazard for utility workers and others in the area.
- Always plug electrical appliances directly into the generator using cords supplied or recommended by the manufacturer. If you are going to use extensions, use ones recommended by the manufacturer. Inspect the cables to make sure they are completely intact and not damaged, cut, or frayed. Never use frayed or damaged extension cords. Make sure the cables are properly rated in watts or amps for the intended use. Never overload a mobile generator; this can lead to overheating of the device which can create a fire hazard.
- Use ground fault circuit interrupters (GFCI) around wet or damp locations. Turn off the mobile generator when you have detected electrical current outside the expected paths. Regardless of GFCI use, the mobile generator must be factory-specified to operate in wet or damp locations.
- Make sure a generator is properly grounded and ground connections are properly tightened.
Consult the manufacturer’s instructions for proper grounding methods. - Always keep the mobile generator dry; do not use it in the rain or wet conditions. If necessary, protect the generator with a waterproof hood. Never handle the electrical components of the generator if you are wet or in water.
- Do not use mobile generators that have been submerged in water. The equipment must be thoroughly dried and properly evaluated by a technician before being used again. Turn it off and do not use the equipment if it smells strange.
2. Carbon monoxide from the exhaust of a mobile generator.
When using a mobile generator you must be very careful to avoid carbon monoxide poisoning from improper use of the equipment.
Carbon monoxide (CO) is a colorless, odorless and toxic gas. Many people have died from CO poisoning because their mobile generator was not running in a properly ventilated area.
- Make sure a mobile generator has 3 to 4 feet of clearance on all sides, as well as above the generator body, to ensure adequate ventilation.
- Never use a generator indoors or in confined spaces. You should be especially careful with spaces like garages and basements. You CANNOT prevent CO from building up when your mobile generator is located in an enclosed space.
- Do not use a generator outdoors near doors, windows, and vents, as this could allow the CO generated by the generator to enter and accumulate in enclosed spaces.
- If you or others show symptoms of CO poisoning such as: dizziness, headaches, nausea, tiredness: Get outside immediately and seek medical attention. Do not re-enter the area where the mobile generator is located until trained and properly equipped personnel determine that it is safe for you.
3. Hazards due to noise and vibrations of the mobile generator.
Generator motors vibrate and generate noise. Excessive noise and vibration can cause hearing loss and fatigue that can affect job performance and compromise your safety.
- Keep portable generators as far away as possible from work areas and meeting spaces.
- Whenever this is not possible, wear hearing protection.
4. Fires from incorrectly refueling a mobile generator or improperly storing it.
Generators get hot during operation and remain hot for long periods after they are turned off. Generator fuels can ignite if spilled on hot engine parts.
- Gasoline and other fuels for generators must be stored and transported in approved containers that are properly designed and
marked by its content. - Keep fuel containers away from flames and heat producing and generating devices.
(these include the generator itself, water heaters, cigarettes, lighters, and matches). Avoid smoking around fuel containers. Generator fuel generates vapors that can travel long distances to ignition sources and start unwanted fires. - Don’t store generator fuels in your home or office. Store fuels away from living areas.
- Before refueling, turn off the generator and allow it to cool completely.
