Generator Maintenance Tips

Owning a generator is more than simply providing a backup power source. After using it, there is a procedure to follow.

  • First, turn the power off
  • Take it away from the ground
  • Then commend it for its excellent performance. If you invest in such a costly device, you would want to maximize its usage.
  • And then save it for later.

Like any other valuable item in your possession, a generator needs regular maintenance and care to maintain its tip-top condition.

Maintaining a generator regardless of its type has nearly similar procedures to bear in mind. Manufacturers include manual guidelines and maintenance schedule charts for each type of generator. So before operating the machine, be sure to read the company’s manual.

A regular inspection practice is vital to ensure the machine components intact and to monitor whether or not it needs replacements and adjustment.

Inspection consists of the following:

  1. Possible leaks – Oil gasket leaks are usually by loose and poorly installed parts, as well as corrosion. When the generator is running, vibration may cause components to become loose. Check to see if the nuts are well fitted and secure—the use of sub-standard nuts causes nuts to be improperly installed.
  1. Oil assessment – It is advisable to change the oil after 100 hours of use. However, if you run your generator for an extended period per day, it can consume a significant amount of oil. And if you haven’t used your generator in a while, you can always change the oil regularly to ensure that it works well when you need it.
  1. Monitor coolant level – Engine coolant is vital in all motor engines. It lubricates the pump bearings and aids in the removal of rust accumulation in the passages. If coolant is inadequate, the engine’s temperature will rise and begin to heat up.
  1. Belts and hose stability –If your generator engine is often loud or emits a high-pitched squealing sound, it may be due to a faulty belt. A sloppy belt will raise the temperature. Change it or adjust it as necessary.
  1. Battery terminal check-up – Allowing your generator to sit idle for an extended time will cause battery damage. Occasionally start the generator. Every three months, charge the battery for 24 hours but don’t overcharge it. When setting a battery, follow the manufacturer’s instructions. At all times, a trickle-charge must be active. Check the voltage with a multimeter and run a load test. Replace your battery every two years to ensure that it is still available for use anytime you need it.
  1. Cables and wiring maintenance – Because of the vibration, it is best to use a flexible wire. The alternators’ connection column or the power switch are not affected if the generator is displaced. Use a wire that meets the generator’s voltage and current output. All wiring to the generator should be checked for fraying, particularly signs of cuts and openings. To avoid an accident, replace broken wires as soon as possible.
Importance of generator maintenance

Generators are our partners in times of power emergencies. It will eventually be exposed to different elements, especially during periods of calamity or disaster.
