ENGINE ADJUSTMENTS
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.
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.
Periodically clean the muffler area to remove com-
bustible debris.

Clean Finger Guard Area: If your BULLDOG™ 5500
is equipped with an engine that has a finger guard,
you should clean it as often as needed, to remove dirt
or debris that may collect on the fin areas. A dirty fin-
ger guard can result in overheating and damaging the
engine. (See Figure D.2).
