Diesel Generator Testing Procedure, Oil Change Frequency & Pre Start Maintenance Checklist

All machinery wears and all machinery needs maintenance. Even hand tools need cleaning, sharpening and other attention, but power machinery requires regular maintenance. If your emergency generator does not function in an emergency you may find yourself in a world of hurt. Lives may be at stake in the case of a hospital. No power no patient monitors, no respirators, no air conditioning and no lights. On a jobsite if the generator or compressor goes down and you have a 20-man crew, in midmorning on a tight schedule averaging more than $40/hour what do you do; send ‘em home? What if you’re working on a remote jobsite? And if the equipment fails because of poor maintenance that’s on you. Last thing you want is for your perimeter lights to go out during the zombie apocalypse. All kidding aside emergency power or remote site power generation is critical and failure due to maintenance issues and the blame falls on you.

Diesel Generator Testing Procedure

Emergency equipment requires testing on a regular basis. The natural gas/propane units are usually self-testing, and fire themselves up and run diagnostics then send the results to your computer or phone if a problem is encountered. Gasoline or diesel engines may or may not be self-testing. Even so on at least a quarterly basis the oil needs checking, liquid cooling systems and fluid level checked, and those with liquid fuel make sure the fuel is topped off and not contaminated. These engine-generators sit for extended periods between runs, a quarterly fire-up and a 30-minute run is the minimum, bi-monthly would be better. Engine oil in these rigs should be synthetics as these resist deterioration better than the standard oils.

Generator Pre Start Checklist

Engines and equipment should be kept clean. During a visual inspection, it is easier to note leaks or electrical arcing on a well-kept rig. Dirt and crud tend to hide many problems. What applies to generators applies to any engine driven machine, compressors being an example. Heavy equipment operators generally check their machinery before morning start-up. Fuel levels and lubrication, including oiled or greased joints. A quick visual inspection and a note to maintenance personnel if any hydraulic leaks are present or if other problems are noted. With stationary equipment like compressors and generators the responsibility lies with whomever is given the task of starting them when work commences.

Generator Oil Change Frequency

Most engine powered equipment are furnished with hour meters to note usage and run time. Given a car’s oil change is set at 3,000 miles and an average of 60 mph, the run time is 50 hours. So as a rule of thumb maintenance intervals should be between 50-100 hours of run time, with the higher value depending on the use of synthetic lubricants. Fuel, engine oil, air and hydraulic system filters should be inspected (air) or changed on the manufacturers suggested maintenance schedule. Generators usually have a bearing front and rear of the armature that will need regular lubrication, oil or grease, and should be done before start-up.

Diesel Generators for Rent, Lease & Purchase

Contractor’s profits depend on productivity and maintaining a production schedule. Failure of any critical equipment will cost time and productivity. In remote locations days may elapse before a replacement or critical part is obtained. Emergency failure may result in dire consequences pertaining to survival. Maintain your tools, hand and/or power, it is safer and more productive. Environmental Power Solutions offers well maintained generators for sale, lease and rent. Contact us to learn more.
