CARBURETOR
The carburetor of your generator is pre-set at the fac-
tory. The carburetor should not be tampered with. If your
generator is used at an altitude in excess of 4000 feet
performance may be affected. If so consult with your
nearest Sears Service Center regarding high altitude set
changes.
GOVERNOR
Your engine governor maintains the constant operating
speed of your generator. DO NOT tamper with the en-
gine governor which is factory set for proper engine
speed.
Low engine speeds impose a
heavy load on the engine and
when sufficient power is not available the engine
life could be shortened.
CLEAN
Clean Guard/Muffler
Do not clean with a forceful spray of water because
water could contaminate fuel system. With a brush or
cloth clean finger guard after every use to prevent
engine damage caused by overheating. Before running
engine, clean muffler area to remove all combustible
debris.
