FUEL FILTER

1.Check the fuel filter and fuel pre-filter for water accumulation or sediment.

2.Replace the fuel filter if it is found with excessive water accumulation or sediment. Empty fuel pre-fil- ter.

OVERSPEED IS HAzARDOUS

The maximum allowable high idle speed for this machine is 3650 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.

ENGINE ADJUSTMENT

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

CLEANING THE bATTERY

Keep the battery clean by wiping it with a damp cloth when dirty. If the terminals appear corroded, discon- nect the battery cables and wash the terminals with an ammonia solution or a solution of 1/4 pound (0.1113 kg) of baking soda and 1 quart (0.9461) of water. Be sure the battery vent plugs (if equipped) are tight so that none of the solution enters the cells.

After cleaning, flush the outside of the battery, the bat- tery compartment, and surrounding areas with clear water. Coat the battery terminals lightly with petroleum jelly or a non-conductive grease to retard corrosion.

Keep the battery clean and dry. Moisture accumula- tion on the battery can lead to more rapid discharge and early battery failure.

CHECKING THE ELECTROLYTE LEVEL

If battery cells are low, fill them to the neck of the filler hole with distilled water and recharge. If one cell is low, check for leaks.
