For a generator to operate effectively and safely, maintenance is necessary. You may need to do different maintenance tasks according to what kind of generator you have. Most generators will require routine services, such as oil changes and filter replacements, once a year or after 50 hours of operation, whichever comes first. 

You are advised to get your equipment serviced for generators at least once a year to guarantee maximum performance and safety. In this article, we will tell you how to service a generator step by step.

1. Standard General Inspection

The first step in learning how to service a generator is to check the exhaust system, the fuel structure, DC electrical wiring, and the motor must all be continuously watched for any leaks that might result in hazardous circumstances. As with any combustion engine, proper maintenance is essential. 

2. Maintenance Service

The 2nd step is how to service a generator at regular intervals: turn off the generator and use a dipstick to inspect the engine oil. Allow the top portions of the engine’s oil to drain into the crankcase and adhere to the API oil class and viscosity specifications the engine’s manufacturer has set. 

Add more oil of the same quality and brand to maintain the oil level near the full mark on the dipstick.

3. System for Cooling

The third step in servicing a generator is monitoring the coolant level during shutdown periods. Open the cap on the radiator and, if required, add coolant after letting the engine cool. Additionally, monitor your coolant filters and change them as necessary. 

A balanced coolant solution of water, antifreeze, and coolant additives is necessary for heavy-duty diesel engines. 

4. Energy System

The fourth step of how to service a generator is the energy system. Generators are prone to contaminants and corrosion within a year. Thus frequent generator set activity is highly advised to burn stored fuel before it degrades. 

The necessary intervals should be used to empty the gasoline filters because the moisture accumulates and condenses in the fuel tank.

5. Recurring use of the generator

The most important step is to run your generator service every month. You should start your generator every month and have good service. Keep the generator running for roughly 30 minutes once a month.

Connect it to a load containing an appliance with a running motor. Use a box fan as an illustration.

This process makes sure that the engine and alternator get some activity. If the monthly run is not practicable, try to operate the generator at least once every three months. The 30-minute time frame is sufficient; extending it is unnecessary. When using or storing your generator after idling for 30 days, reapply new and commercial oil stabiliser.

6. Adding power to the battery

You should charge the batteries once a month, just like you should for the engine and alternator. Charge it for a day during each charging interval. Charging too much or too little can be detrimental.

7. Storing the Unit 

You must be sure to look for these things when keeping the generator:

  • Ignition plug cap
  • Replacement of the fuel filter
  • Service for spark arrestors
  • Valve modification

The best action is to speak with a licensed repair dealer because poor adjustment can harm your generator.

Frequently Asked Questions ( FAQs)

  1. What kind of fuel should I use, exactly?

Most gas models should use unleaded fuel (at least 87 octane; check your manual to ensure). Before refuelling, shut off the engine and allow it to cool.

  1.  How can I replace the air filter?

Your generator maintenance schedule should include routine air filter checks. Engines use a variety of air filters, but they all work on the same principle: when one becomes clogged and can no longer pull the required volume of clean air (or the engine has to work too hard to do so), it needs to be replaced. 

Some air filters are flat pieces, some are flat pieces with centres, and some are rings without centres. To learn how to change the air filter in your generator, consult the owner’s manual.

  1.  Is using a generator indoors safe?

No, a lethal gas called carbon monoxide is produced by engines that run on fuels like gasoline and diesel. This gas is extremely harmful because it has no flavour or colour and is also fatal.

  1. How should my carburettor be cleaned?

Carburettor cleaning is a more difficult job that is best left to a professional. To properly clean it, you must disassemble the carburettor and use carburettor cleaner on the inside. You must unhook the gasoline line and remove the fuel tank to get it off.

Key Takeaways

When the primary power source fails, industrial establishments must have a generator as backup power. It’s crucial to do generator care. Since generators are infrequently utilised, it is frequently disregarded. Major calamities can result from generator failure; hence generator maintenance must be addressed seriously.

You should do yearly maintenance on your generator to guarantee smooth long-term operation. You can perform this yearly checkup yourself or hire a qualified specialist.
