SAFETY PRECAUTIONS

• 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.

• 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 300.

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.

ROUTINE AND PERIODIC
MAINTENANCE

Refer to Figure D.2 for the location of maintenance
components.

ENGINE MAINTENANCE

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

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 tem-
peratures, 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.

Replace the plug and tighten it securely.

Remove the oil fill cap and add oil until the level
reaches the “MAX” mark on the dipstick. Use high
quality detergent oil of API service class CD or bet-
ter, oil viscosity grade 10W30. Consult the engine
manual for oil specifications for various ambient
temperatures. Always check the level with the dip-
stick before adding more oil.

4. Reinstall the oil fill cap and the dipstick.
