FUEL: At the end of each day’s use, refill the fuel tank to minimize moisture conden- sation and dirt contamination in the fuel line.

ENGINE ADJUSTMENTS

WARNING

OVERSPEED IS HAZARDOUS - The maximum allowable high idle speed for this machine is 3750 RPM, no load. DO NOT tamper with the governor components or setting or make any other adjust- ments 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.

CAUTION

Do not use petroleum solvents such as kerosene to clean the air cleaner. They may cause deterio- ration of the air cleaner. DO NOT OIL THE AIR CLEANER OR USE PRESSURIZED AIR TO CLEAN OR DRY THE AIR CLEANER.

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

To service the pre-cleaner:

1.Wash in liquid detergent and water.

2.Squeeze dry in a clean cloth.

3.Saturate in clean engine oil.

4.Squeeze in a clean, absorbent cloth to remove all excess oil.

CLEAN ENGINE: Remove dirt and debris with a cloth or a brush. Do not clean with a forceful spray of water. Water might contaminate the fuel system.

CAUTION

Periodically c lean the m uffler a r ea to r em ove combustible debris.

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

Clean Rotating Screen: If your POWER-ARC 5500 is equipped with an engine that has a rotating screen, you should clean it as often as needed, to remove dirt or debris that may collect on the screen. A dirty screen can result in engine overheating and damage. (See Figure D.3).
