Procedures
3Checking Generator Drive Plate Torque maintenance
- Disconnect the engine starting battery
- Remove the generator fan guard
- Torque each of the drive plate bolts to the specification (MMG330: 33 ft-lb / 45 Nm)
- Reinstall the generator fan guard and reconnect the battery
Resetting of the Time to Service Reminder maintenance
- With the unit shut down, power up the controller with the Control On/Off toggle switch
- Press Page Select until Engine Protect line is reached and press Enter
- "WrnMaintanance" appears with the current service time hour setting below it
- Press Enter; current run time in hours appears on the display
- Reset the current run time hour setting to 250
- Press Enter to save the run time hour setting
- Move the Control On/I toggle switch to Control Off/O
Towing the Trailer / Wheel Lug Torque Sequence maintenance
- Start all lug nuts by hand
- First pass: tighten to 20-25 ft-lbs (27-33 Nm)
- Second pass: tighten to 50-60 ft-lbs (67-81 Nm)
- Third pass: tighten to 90-120 ft-lbs (122-162 Nm)
- After the first road use, re-torque the lug nuts in sequence

Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Wrn RA15 fail — Warning alarm in case of lost connection to IGL=RA15 module | Lost connection to IGL=RA15 module | |
| WrnMaintenance — The period for servicing is set by the WrnMaintenance setpoint; the protection comes active if the running hours of the engine reach this value | Running hours of the engine reach the WrnMaintenance setpoint | Reset the "ServiceTime" reminder to the 250 hour interval |
| CheckDPFStatus — Engaged when the Diesel Particulate Filter needs attention | Diesel Particulate Filter needs attention | |
| Low fuel level shut down | Fuel level low; leaks in the fuel tank; fuel level sender and connecting wiring damaged | Check the fuel level on the LCD window and confirm the generator is sitting level; check for leaks in the fuel tank; check the fuel level sender and the connecting wiring for damage and check for continuity between the sender and the engine controller |
| Low oil pressure shutdown | Low engine oil level; oil leaks; loss of oil pressure; oil pressure sender fault | Check the level of the engine oil with the dipstick and add oil if required; visually inspect the engine for oil leaks; restart the unit and verify the loss of oil pressure, shutting the engine down immediately if the oil pressure value does not read 5 psi (34kPa) within 5 seconds; check the oil pressure sender and refer to the troubleshooting section of the engine operation and maintenance manual |
| Low coolant level shut down | Low coolant level; visible leaks in coolant hoses, engine block or water pump; coolant mixed with engine oil | Allow the engine to cool; check the coolant level in the radiator and add coolant until it is 3/4 in (2 cm) below the filler neck; inspect coolant hoses, engine block and water pump for visible leaks; check the engine oil to verify no coolant has mixed with it and consult the engine operation and maintenance manual |
| High coolant temperature shut down | Low coolant level; radiator shroud and ducting blockage; visible leaks in coolant hoses, engine block or water pump; loose serpentine drive belt for the water pump; engine overheating | Check the coolant level in the overflow jug; restart the engine and read the coolant temperature to verify High Coolant Temperature shut down, stopping the engine immediately if the coolant temperature is 230°F (110°C) or more; allow the engine to cool, add coolant to the overflow jug if low and check the radiator level, adding coolant until it is 3/4 in (2 cm) below the filler neck; check the radiator shroud and ducting for blockage and remove any foreign matter; inspect coolant hoses, engine block and water pump for visible leaks; check the tension of the serpentine drive belt for the water pump; remove the load on the generator and restart the engine, checking the coolant temperature and shutting the engine down immediately if it starts to overheat, and consult the engine operation and maintenance manual |
| Overcrank shut down | Low fuel level in the tank; fuel pump not operating properly; air filter blockage; engine will not start | Check the fuel level in the tank; check for proper operation of the fuel pump; check air filter for blockage; if the engine will not start, consult the engine operation and maintenance manual for additional information on troubleshooting starting problems |
| Overspeed or underspeed shut down | Engine speed above or below 60.0 Hz | Disconnect all loads and restart the generator, read the frequency (Hz) on the LCD display (with no loads the frequency should read 60.0 Hz); if the frequency is above or below 60.0 Hz, adjust the engine speed per the engine manual for throttle adjustments on mechanical governed units and the electronic governor manual for electronically controlled units |
