daily
Checking whether leakage of fuel, coolant and lube
Checking coolant preheater, starting will fail if temperature is too low
Checking battery recharger

weekly maintenance
Checking liquid level for lube and coolant
Checking battery charger

monthly maintenance
Checking air-logged indicator of air filter
Checking genset whether has unusual vibration, excessive exhaust, noise and coolant, fuel leakage. Regularly test running lubricable component t enhance the reliability for starting; Preventing oxidization for connection terminal; Avoiding fuel degeneration. No-load running 2 times for 10-15 minute everymonth. 
Checking whether leakage or looseness of radiator
Checking fuel elevation and transit pump condition
Checking whether leakage or over-resist in exhaust system, discharge condensation liquid.
Checking battery and connecting condition for battery cable
Checking vent resistance of air inlet, checking whether maintenance kit are prepared

semi-annual maintenance
Checking lube and bypass filter Clean or replace ventilation filter for crankcase
Discharge sediment from fuel tanker, checking whether any damage of fuel pipe and checking electric control and alarm system
Cleaning grease, lube, dust and sediment on generator set
Checking contact of power transmission cable, breaker and switch.
Checking start function and performance with rated load by emulate outage public power, checking ATS and related configuration.

annual maintenance
Check the fan blades, pulleys and pumps.Checking fan in radiator, belt wheel and pump
Tighten fastening
Cleaning output and control box, checking and fasten all the wire contact, measuring and recording insulation resistance, checking heater in alternator.
Manual operating to check main circuit breaker, verifying auto trip function according manual.
At least running the machine 4 hours with 5% loading a year if the generator set would just no-load or light-load
Testing insulation condition if machine room had been flooded or too wet. Implement preliminary testing before finally testing, and take it as benchmark for routine testing
For standby generator set, it should be maintenance thorough annual, including replace lube, lube filter, coolant filter, fuel filter, air filter.
