SAFETY PRECAUTIONS

WARNING

Have qualified personnel do all maintenance and troubleshooting work.

Turn the engine off before working inside the machine.

Remove covers or guards only when necessary to perform maintenance and replace them when the maintenance requiring their removal is complete.

ROUTINE AND PERIODIC

MAINTENANCE

ENGINE MAINTENANCE

CAUTION

To prevent the engine from accidentally starting, dis- connect the negative battery cable before servicing the engine.

If covers or guards are missing from the machine, get replacements from a Lincoln Distributor.

Read the Safety Precautions in the front of this manu- al and in the instruction manual for the diesel engine used with your machine before working on the Commander 400.

Keep all equipment safety guards, covers, and devices in position and in good repair. Keep your hands, hair, clothing, and tools away from the fans, and all other moving parts when starting, operating, or repairing this machine.

See Table D.1 for a summary of maintenance intervals for the items listed below. Follow either the hourly or the calendar intervals, whichever come first. More fre- quent service may be required, depending on your spe- cific application and operating conditions.

OIL: Check the oil level after every 8 hours of opera- tion or daily. BE SURE TO MAINTAIN THE OIL LEVEL.

Change the oil the first time between 25 and 50 hours of operation. Then, under normal operating conditions, change the oil as specified in Table D.1. If the engine is operated under heavy load or in high ambient temper- atures, change the oil more frequently.

CHANGE THE OIL: Change the oil, while the engine is still warm, as follows:

1 . Drain the oil from the drain plug located on the engine bottom, as shown in Figure D.1. Examine the washer and replace it if it appears damaged.

2.Replace the plug and washer and tighten firmly.

3.Remove the oil fill cap and add oil until the level reaches the “MAX” mark on the dipstick. See Figure D.1. Use high quality oil viscosity grade 10W40. Consult the engine manual for oil specifi- cations for various ambient temperatures. Always check the level with the dipstick before adding more oil.

4.Reinstall the oil fill cap and the dipstick.
