GENERAC SERVICE - PARTS
We now only do Generac generator service and repairs. We no longer do new generator installs.
Yearly maintenance costs for Air-Cooled Generators 7 KW to 24KW includes everything in the 25 point checklist. $235.00. The following is our 25-point Preventive Maintenance Checklist for Air-Cooled Generators:
- Clean inside and out
- Wax outside
- Wipe protective coating on rubber bellows and hoses
- Change oil (5W-30 Mobile 1)
- New Generac Oil filter
- Update firmware on EVO panels
- Check and (or) replace Air Cleaner
- Clean and (or) replace Spark Plugs and gap
- Check Voltage (approx. 240 volts)
- Check Frequency 60 HZ
- Check automatic operation
- Check and write down run time hours
- Check and write down Cold Cranking Amps (CCA) on battery. If below 440 CCA then replace battery
- Spray terminal protector on battery terminals
- Adjust valves on generators that run rough or break-in maintenance is being done
- Check fuel pressure (5-7 W.C. for NG and 11-14 W.C. for LP)
- Fuel line inspection
- Check choke operation
- Check to make sure Circuit Breaker is ON
- Check to make sure generator is set to AUTO before leaving
- Reset Maintenance (yellow light)
- Make sure both plug wires are connected
- Check battery connections. Tighten and spray with anti-corrosion
- Install maintenance tag. Record what was done on tag: new oil, new oil filter, air filter, new plugs, CCA of battery or new battery, hours, date
- Re-check oil level and tighten oil Cap
- Generac recommends a new battery every 2-3 years. Usually 4-5 years is fine with the Duracell batteries we use as long as Cold Cranking Amps is above 440 CCA
