MAINTENANCE

Safety Precautions

WARNING

Have qualified personnel do the maintenance work. Turn the engine off before working inside the machine . In some cases, it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts.

Do not put your hands near the engine cooling blower fan. If a problem cannot be corrected by following the instructions, take the machine to the nearest Lincoln Field Service Shop.

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

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.

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

ENGINE EXHAUST can kill.

• Use in open, well ventilated areas or vent exhaust outside.

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

MOVING PARTS can injure.

Do not operate with doors open or guards off.

• Stop engine before servicing.

Keep away from moving parts.

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

See additional warning information at front of this operator’s manual.

Engine Adjustments

WARNING

OVERSPEED IS HAZARDOUS

The maximum allowable high idle speed for this machine is 3750 RPM, no load. Do NOT tamper with governor components or setting or make any other adjustments to increase the maximum speed. Severe personal injury and damage to the machine can result if operated at speeds above maximum.

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

Adjustments to the engine are to be made only by a Lincoln Service Center or an authorized Field Service Shop.

Routine Maintenance

1.At the end of each day’s use, refill the fuel tank to minimize moisture condensation in the tank. Running out of fuel tends to draw dirt into the fuel system. Also, check the crankcase oil level and add oil if indicated.

2.OIL - Maintenance schedule for changing the oil and oil filter after break-in:

 

Kohler

Onan

 

CH20S

P218

 

 

 

Oil

100 hr

50 hr

 

 

 

Oil Filter

200 hr

100 hr

 

 

 

The above schedule is for normal operating condi- tions. More frequent oil changes are required with dusty, high temperature, and other severe operating conditions. Refer to the maintenance section of the Engine Owner’s Manual for more information.

CAUTION

Engine life will be reduced if the oil and oil filter are not changed according to the manufacturer’s recommendation.

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

3.Air Cleaner - With normal operating conditions, the maintenance schedule for cleaning and re-oiling the foam pre-filter is every 25 hours and replace- ment of the air cleaner filter every 100 hours. More frequent servicing is required with dusty operating conditions. Refer to maintenance section of the Engine Owner’s Manual for more information.

4.Refer to the maintenance section of the Engine Owner’s Manual for the maintenance schedule for spark plug servicing, cooling system servicing, and fuel filter replacement.

CAUTION

Make certain that the oil filler cap is securely tightened after checking or adding oil. If the cap is not tight, oil consumption can increase signifi- cantly which may be evidenced by white smoke coming from the exhaust.

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

5.Blow out the machine with low pressure air periodi- cally. In particularly dirty locations, this may be required once per week.

6.Output Ranger Selector and Polarity Switches: Switch contacts should not be greased. To keep contacts clean, rotate the switch through its entire range frequently. Good practice is to turn the han- dle from maximum to minimum setting twice each morning before starting to weld.
