Preventative Maintenance for your Generator

Our highly qualified generator technicians can help to assure that your generator will provide the needed power for your home or business during planned or unplanned power outages.

You may choose from the following recommended Preventive Maintenance (PM) options or set your own intervals for scheduled planned maintenance to occur.

Inspection: (Recommended Interval – Every 6 Months)
74 point inspection covering critical items such as your Engine, Generator, and Transfer Switches. The Full Service also includes oil and oil filter replacement, fuel filter replacement and coolant filter replacement if applicable. Air filters will be checked but will only be changed if needed (only with approval from the customer).

Inspection Full Service: (Recommended Interval – Every 12 Months)
(If unit is used for Prime Power, recommend changing oil every 6 months or 250 hours, whichever comes first)

Load Bank Testing: (Recommended Interval – Every 12 Months)
(Annual test is REQUIRED for Hospitals and other life support providers if a load of 30% of the generator set’s nameplate rating cannot be achieved during the required monthly test.)
Optional 2 or 4 hour testing.  Minimizes potential of issues related to moisture build-up, settling of particles in fuel and carbon deposits in engine.  This is not only a recommended test, but per JCAHO and Public Health regulations, is a requirement for facilities providing life support systems, i.e. hospitals and nursing homes.

Coolant System Flush: (Recommended Interval – Every 24 Months)
Reduces sediment buildup which could cause corrosion in coolant piping and tanks.

Belts and Hoses Replacement: (Recommended Interval – Every 24 Months)
Replacement of belts and hoses reduces risk of failure which could cause further damage to engine.

Fuel Cleaning: (Recommended Interval – Every 24 Months)
Reconditions, stabilizes and decontaminates fuels. It efficiently removes water, sludge and sediments that naturally accumulate in tanks.

Battery Replacement: (Recommended Interval – Every 24 – 36 Months)
Batteries are load tested with Carbon Pile testing. Remove and replace batteries if between two and three years old at time of Inspection or Full Service Inspection. Includes disposal of old batteries.
