Lincoln Electric IM612 manual BREAK-IN Period, Table B.1 Typical Ranger 8+ Diesel Fuel Consumption

B-6 OPERATION B-6

BREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the diesel engine on the RANGER 8+ DIESEL, break-in is about 50 running hours.

Check the oil every four hours during break-in. Change the oil after the first 20 hours of operation, then at 100 hours of operation, then every 200 hours thereafter. Change the oil filter at every second oil change.

CAUTION

During break-in, subject the RANGER 8+ DIESEL to moderate loads. Avoid long periods running at idle. Before stopping the engine, remove all loads and allow the engine to cool several minutes. Care should be taken that the engine is not run at very light loads for extended periods as this can lead to glazing of the cylinder bores. On the other hand, it is wise not to exceed 70% of the maximum output of the engine for the same period while bearing surfaces are bedding in. Cylinder glazing can lead to excessive oil con- sumption and smoky exhaust, while overloading of the engine during the first few hours can lead to excessive wear and shorten the life of the engine.

WELDING OPERATION

WARNING

Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists.

------------------------------------------------------------------------

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground

•Always wear dry insulating gloves.

------------------------------------------------------------------------

FUMES AND GASES can be dangerous.

•Keep your head out of fumes.

•Use ventilation or exhaust to remove

fumes from breathing zone.

------------------------------------------------------------------------

MOVING PARTS can injure.

•Do not operate with doors open or guards off.

• Stop engine before servicing.

•Keep away from moving parts.

------------------------------------------------------------------------

WELDING SPARKS can cause fire or

explosion.

• Keep flammable material away.

------------------------------------------------------------------------

ARC RAYS can burn.

• Wear eye, ear and body protection.

------------------------------------------------------------------------

See additional warning information throughout this operator’s manual.

-----------------------------------------------------------

The RANGER 8+ DIESEL machines can deliver from 40 to 250 amps of constant current for AC stick weld- ing and 40 to 225 amps of constant current DC stick welding. The RANGER 8+ DIESEL can deliver 40 to 200 amps of constant voltage current for DC semiau- tomatic wire feed welding. AC/DC constant current TIG welding is possible across the entire range from 40 to 250 amps. 250 amps is the maximum recom- mended for AC TIG welding of aluminum.

Output can be adjusted by setting the POLARITY SWITCH, the OUTPUT RANGE dial, and the FINE CONTROL dial on the output control panel to the set- tings that are best for your selected welding process.
