Removal of the device from the exhaust system is not necessary for servicing. Proceed as follows to service spark arrestor:

1.Stop the engine, and allow the exhaust system to cool.

2.Remove the cleanout plug from the bottom of the spark arrestor. If a crust has formed over the hole, break it loose with a screwdriver or similar tool.

3.Start the engine, and run it at idle rpm to blow col- lected particles out the cleanout hole. If particles are slow to discharge, momentarily cover the end of the exhaust stack.

4.Stop the engine, and allow the exhaust system to cool.

5.Replace and secure the cleanout plug.

8-12. RUN-IN PROCEDURE

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

•Stop engine before inspecting, connecting, or servicing.

•Do not leave live unit unattended when engine is running.

•Keep all panels, covers, and guards securely in place while engine is running.

MOVING PARTS can cause severe injury.

•Keep away from moving parts such as fans, belts, and rotors.

HOT ENGINE PARTS can cause severe burns.

•Wear protective gloves and clothing when working on hot engine parts or components.

CAUTION: LOW OIL LEVEL can damage engine; ENGINE MAY USE OIL AND WETS- TACKING may occur during run-in period.

•Check oil level several times a day during run-in period, and add oil if required.

•See engine Owner’s Manual (Deutz F4L-912 diesel engine) for run-in informa- tion.

•Do not idle engine longer than necessary during run-in period.

•Piston rings seat faster if engine runs at weld/power rpm, and the welding generator is kept loaded during the run-in period.

The run-in procedure for diesel engines is different than those associated with gasoline engines. Diesel engines must be run at near-rated load during the run-in period to ensure proper seating of piston rings and to prevent wetstacking. Wetstacking is an accumulation of un- burned fuel and oil in the exhaust pipe. Wetstacking can

occur during the run-in period if the engine is left at idle rpm too long, or the welding generator is not heavily loaded.

If wetstacking occurs, complete one of the following pro- cedures to dry the engine (see engine Owner’s Manual, F4L-912 diesel engine). A resistance load is required to fully load the generator during the run-in procedure. A load bank or resistance grid may provide a constant load for run-in, however, a load bank is preferred. If a load bank is available, proceed with the run-in procedure pro- vided in Subsection A. If a resistance grid is being used, proceed to Subsection B.

A.Run-In Procedure Using Load Bank (Diagram 8-1)

WARNING: Read and follow safety infor- mation at beginning of entire Section 8-12 before proceeding.

1.Stop engine.

IMPORTANT: Weld cables supplied with load bank may be inadequate for run-in procedure. Use weld cables of proper size with appropriate connectors to connect load bank to generator (see load bank Owner’s Manual).

2.Connect cables from load bank to generator weld output terminals observing correct polarity (see Diagram 8-1).

3.Place all load switches in the OFF position.

IMPORTANT: If load bank requires 115 volts ac, it may be connected to the welding generator auxiliary power terminal strip, if applicable.

4.Place welding generator AMPERAGE & VOLT- AGE ADJUSTMENT control in the minimum po- sition.

5.Start engine as instructed in Section 7-6, and al- low engine to warm up for approximately three minutes.

6.Adjust load bank switches and generator controls to provide a load equal to rated generator output.

For example, if rated generator output is 350 am- peres, 40 volts at 100% duty cycle, adjust switches until values indicated by load meters equal rated generator output.

7.Allow engine to run under load for at least one hour. Check engine and load bank meters after the first five minutes and every 15 minutes there- after to be sure equipment is operating properly.

8.After running engine under load for at least one hour, remove load by shutting down load bank.

9.Allow engine to idle for approximately three min- utes to permit internal engine temperatures to equalize.
