A Generator Maintenance Checklist for Diesel Generators

An industrial generator (a.k.a. genset) can endure for decades, but only if it's properly maintained. Even though a generator contains few moving parts, it contains sensitive components that need regular attention. If you require a schedule for performing those measures, here's a basic checklist for diesel generator maintenance on a daily, monthly, semiannual, and annual basis.

Daily Measures

Diesel generators should get the following steps on a daily basis:

General review - Assess the genset for loose parts, signs of corrosion on parts, traces of carbondioxide, and dust build up.

generation service - check that the gas amount and put in fuel as needed.
Charge-air piping assess - be sure the charge-air piping is attached securely to the radiator and also inspect it for signs of wear.
Maintenance personnel commonly execute the measures previously. Generator technicians may also perform them as part of a scheduled support agreement.

Weekly Measures

Diesel generators should get the subsequent steps on a daily basis:

Air cleanser check - Assess that the air cleaner for debris and wash it as necessary.
Battery charger check - Assess that the float voltage scanning on the battery charger and then fix the voltage as vital.
Fuel Filter Drain - clean the water out of the bottom of the fuel filter housing.
Fuel Tank Drain - Drain the water out of the bottom of the fuel tank until the petrol fuel appears.
Most centers have generator technicians perform the weekly measures on a chainsaw maintenance checklist. If construction maintenance personnel perform themthey should have trained in generator maintenance.

Daily Steps

Diesel generators must have These steps performed on a monthly basis:

Coolant concentration check - Take a sample of this coolant with a hydrometer and check its concentration by referring to the ceremony manual from the manufacturer.
Drive belt tension check - Assess the belt for proper tension and inspect it for signs of wear.
Exhaust condensate drain - Drain the condensate from the condensate trap.
Battery check - Check the charge on the battery and also analyze the links for looseness and rust.
As the correct concentration of air in an outdoor generator might be influenced by climate, a chainsaw technician which focuses primarily on emergency power equipment in the Carolinas should perform the coolant immersion test.

Semi Annual Measures

Oil and filter change - Alter the oil and oil filter, regardless of whether the genset was utilized in a non-simulated power outage.
Coolant filter shift - Alter the filter, whether or not the genset was found in a non-simulated power outage.
Crankcase breather cleanup - Clean the crankcase breather in line with the service manual from producer.
Air cleaner element vary - Alter the air cleaner part, irrespective of the level of debris accumulation.
Radiator hose check - Assess that the text of this radiator hoses and inspect them for signs of wear.
Fuel filter change - Change the fuel filter, so regardless of the level of sediment accumulation.
Generator technicians should conduct the measures above.

Annual Measures

The genset should have a thorough yearly cleaning of its cooling system.


The measures above are needed for a diesel generator to stay in excellent condition. By incorporating them into a generator maintenance checklist, you can prepare the generator in your centre for the next power outage.
