Generator Maintenance

Make sure your generator power is operating at peak performance.
Generator Maintenance

The best way to ensure the continuous operation of your power generation equipment is with an ongoing maintenance program.  Weld Power Generator takes a proactive approach toward our emergency power system maintenance programs. Our plans help maximize the life of your generator equipment, minimize downtime, and prevent the inconvenience and cost of unplanned outages due to equipment failure.

Weld Power Generator will carry out thorough inspections at regular intervals, monitor performance, and identify and address issues before problems occur.  We provide maintenance contracts for all makes and models of generators and transfer switches.

Replacement parts are readily available from our extensive and comprehensive parts facility, keeping downtime to a minimum. And because we aim to identify when parts will need replacing, from minor parts to major overhauls, we can help you budget and prioritize even the most complex multi-site, diverse equipment portfolio.

We make sure that your equipment is in the best possible operating condition, meets the industry standards, and exceeds all National Fire Protection Association (NFPA) and Joint Commission on Accreditation of Healthcare Organizations (JCAHO) inspections.

From maintenance contracts with remote monitoring to emergency on-site repairs and rentals, you can rely on Weld Power Generator to keep your business running.

Inspection Scope of Work

Regular, structured inspections as part of an ongoing, comprehensive maintenance plan mean:

  • Outage time is reduced to a planned minimum
  • The equipment is continually evaluated
  • Potential problems can be addressed before they result in serious failure

Weld Power Generator can work on the entire power system including the transfer switch.  We can tailor an inspection program to suit your facility needs.

The inspections are typically classed as either Major (PM2) or Minor (PM1) inspections

Preventative Generator Maintenance – Semi-Annual Inspection

PM1 (Minor) Service Inspection

Walk-around inspection

  • Visual inspection of generator and environment.
  • Perform Lamp / Bulb test 
  • Check for signs of rodent/insect activity.  

Fuel System

  • Check and record fuel tank level (if equipped with gauge)
  • Visually inspect the fuel tank and fuel piping for any indication of leaks.
  • Inspect fuel lines and connections for leaks.
  • Inspect for water in the fuel tank.

Natural Gas or Propane Generator Sets

  • Inspect engine gas lines, regulator, and carburetor for signs of leaks/corrosion.
  • Inspect ignition system (magneto/distributor/spark plugs/wires). 

Starting System

  • Inspect batteries for proper electrolyte level
  • Check battery charger for proper operation and record voltage reading.
  • Check and record the last date that batteries were replaced.  Recommend that batteries be replaced every three years, regardless of condition per NFPA 110 recommendations.
  • Perform battery test(s).

Lubrication System

  • Verify the oil level is between “add” and “full” marks on the dipstick.
  • Check for signs of oil leaks.
  • Inspect the condition of the air filter. 

Cooling System

  • Inspect radiator/heat exchanger for leaks, exterior cleanliness, and/or deterioration.
  • Check the condition of the coolant.
  • Check and record the coolant level.
  • Inspect hoses and connections for signs of wear or cracks.
  • Inspect fan drive pulley and fan for signs of wear or cracks.
  • Inspect fan drive belts for signs of cracking or deterioration.
  • Confirm jacket water heater is working (engine not running).
  • Inspect the water pump for any indication of leaks.

Control Panel

  • Verify gauges are operating properly
  • Check for the presence of any warning lights/alarms.

Operational Checks with Engine Running

  • Verify the engine starts and runs normally. 
  • Record voltage, frequency & oil pressure.
  • Check the DC alternator charge rate.
  • Verify engine temperature after a 15 min run. 
  • Check for proper air inlet and outlet louver operation (if equipped).

Conclusion of Visit/Recommendation

  • Control panel: confirm control switch is in “auto” position
  • Circuit breaker: confirm breaker is in the “ON” position.
  • Offer a building load test. 
  • Provide written recommendation(s) for any suggested repairs.
  • Speak with the end-user and discuss any problems.

PM2 (Major) Service (Inspection Plus Oil Change)

Perform all work required under PM1 Inspection plus:

  • Replace lubricating oil and lubricating oil filters and fuel filters. 
  • Obtain oil sample (via sample port with engine running)
  • Obtain coolant sample and send out for laboratory 

Power. Anytime. Anywhere.
