Maintain your generator to keep it working well

A portable generator is an incredibly powerful investment and serves several important purposes. These range from domestic and recreational and even for trade and industrial. It is a go-to solution in case of a power outage. It also acts as a safety valve when traveling or in times of emergency. It is important to maintain it properly so that it remains reliable whenever you need it. The following are some important portable generator maintenance tips. These should help you increase your machine’s longevity.

Use fresh oil

Changing the oil is a key factor in maintaining your small engine power equipment. Most generators require their first oil change within 25 to 30 hours after its first use. After the first oil change, the next ones should be after every 100 hours of use or at least once every season. Make sure to use fresh oil every time. It is also better to store oil and filter supplies. You’ll be better prepared for unexpected, extended power outages.

Invest in a cover or enclosure

A cover or an enclosure would be a sound investment if you have a portable generator. This will help protect your equipment from wind, rain, bugs, dirt and dust particles. You have to keep these elements from getting inside or forming a layer on any part of your generator. They may cause damage and affect its performance. When you invest in a generator cover, make sure that it leaves enough space for easy handling and release of toxic gases.

Run your generator on a regular basis

Like any other machine, a portable generator is built to be used. Leaving it unused for a long time may lead to malfunction and rust. Generator manufacturers encourage owners to run their generator on a regular basis. Do it for at least half an hour as this will ensure that the battery of the electric starter is charged. Doing this helps avoid any issues related to an ineffective engine. It will guarantee a smooth operation.


Make it a habit to check the engine oil of your generator before shutting it down. Do this at regular intervals.  Drain the oil in the upper portions of the engine into the crankcase. Take note of the oil viscosity as well as the oil classification. Also make sure to keep the oil level as near as possible to the full mark.

Let the engine cool down

Make sure to let the engine of the portable generator cool down every after use. Do it by removing the radiator cap. You may also opt to add coolant until the level reaches about three-fourths inch. Also clean the exterior of the machine and get rid of any obstructions. Remove dust particles and dirt using a cloth. Check coolant level on a regular basis.

Inspect batteries

One of the reasons why generators fail is because of dead or weak batteries. Make sure your batteries are always fully charged and working well. This will ensure that your portable generator is working when you need it most. Do a regular inspection of the batteries to keep your machine well-maintained.

Drain old fuel

Drain your generator of old fuel before using it

Fuel storage is another top consideration when you have a portable generator. If you haven’t used your generator for a while and it is still filled with old fuel, make sure to drain the old fuel before your next use. Old fuel can get contaminated and may cause damage to your generator.

Do not let it run dry

Make sure your generator does not run out of fuel. When it runs out of gas, chances are your home appliances will draw the magnetic field of your generator as soon as the power stops. This may lead to a serious damage to your machine.

Owning a portable generator can make our lives convenient especially during emergencies. So make sure your machine is safe and secure by following these maintenance tips. If all else fails and you need reliable portable generator repair services, please contact Greg’s Small Engine.
