Generac Gaseous Generators MGG210: Daily Walk Around Inspection Maintenance

This procedure is for the daily maintenance of your generator. Daily checks must be performed when the unit is operated continuously for extended periods of time. The maintenance procedure will help you look for conditions that could hinder performance or safety such as (but not limited to) oil, coolant, gas (well, natural leakage, etc).

    MAINTENANCE TASKS

    Daily checks must be performed when the unit is operated continuously for extended periods of time. Daily checks and routine monthly checks can be performed by an authorized operator.

    Verify the trailer is as level as possible and that the tires are blocked. Verify the radiator and exhaust areas are clear of debris.

    Daily Walk Around Inspection

    Look for conditions that could hinder performance or safety, such as (but not limited to) oil, coolant, gas (well, natural) leakage, blocked vents, loose or missing hardware and electrical connections. Check for foreign matter blocking the vents and on top of the unit.

  • When the unit is not running:

  • Check Engine Fluids

  • The following checks can be performed by a trained authorized operator. Observe all safety precautions outlined in the Safety section.

  • Check Engine Oil Level

  • This unit is equipped with an auxiliary engine oil reservoir and automatic float valve. When checking the engine oil, the reservoir should also be checked.

  • Add oil as needed via the oil reservoir. Open the valve and allow oil to drain into the controller until the sight glass is approximately halfway full while running, or near the top of the controller sight glass while the unit is shut down. The dipstick can be used to verify correct oil level while the genset is off. The valve may be left open. Close the valve before moving the unit.

  • To check the engine oil using the dipstick:

  • Typical causes of inaccurate oil level readings:

  • Changing the Oil

  • Note: When changing oil, it is not necessary to drain the oil from the reservoir.

  • Check Fuel System

  • Check gas pressure. At the well fuel inlet, the well gas should be a minumum of 10 psi (69 kPa) and a maximum of 20 psi (138 kPa).

  • Note: The regulator mounted off of the fuel separator should be set to 13-1/4 in. (34 cm) WC before running, and 12-3/4 in. (32 cm) WC while running. The regulator should only be set during field set up by an Authorized Technician.

  • The fuel/water separator tank should be drained every 24 hours of run time. Prior to draining the fuel/water separator, place a drain pan under the hose to collect any debris. With no open flame or other ignition source in proximity, open the valve and let the water drain only until the water flow diminishes, then immediately close the valve. Follow local and state ordinances for the proper disposal of the drained liquid/debris.

  • Check Coolant Level

  • Observe the following precautions when working on batteries:

  • Lead-acid batteries present a risk of fire because they generate hydrogen gas.

  • Be sure the control power switch is set in the OFF position before connecting the battery cables. If the switch is set to AUTO or MANUAL, the generator can crank and start as soon as the battery cables are connected.

  • Be sure the utility power supply to the battery charger is turned OFF and the 10A and 15A fuses are removed from the generator control panel and the ATC style fuse removed from the battery charger, or sparking may occur at the battery posts as the cables are attached and cause an explosion.

  • Note: A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the generator set.

  • Periodic inspection, service, and maintenance of this unit is critical in ensuring its reliable operation. The following is the manufacturer’s recommended maintenance schedule. The maintenance items will need to be performed more frequently if the unit is used in severe applications (such as very high or very low ambient conditions or extremely dirty/dusty environments). Use the unit hour meter or calendar time, whichever occurs first, from the previous maintenance interval to determine the next required ma

  • MAINTENANCE SCHEDULE

  • Note: An authorized operator is one who has been trained by a Manufacturer Authorized Service Dealer in the proper operation and inspection of this generator set.

  • Use the schedule in the following table as a guide for regular maintenance intervals. For additional or replacement copies of the engine operator’s manual, contact an authorized dealer in your area.

  • Daily Maintenance Procedure:

  • OTHER MAINTENANCE CHECKS

  • The following inspections should be performed by a qualified/authorized service technician, or a properly trained authorized operator. These maintenance items require a high level of experience and skill to evaluate and correct.

  • NOTICE!

  • All recommended service maintenance or repairs should be completed by an authorized service technician to maintain the warranty status of a unit.
