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.

Over-speeding your engine above factory high speed set- ting can be dangerous and could possibly cause per- sonal injury or property damage. If you believe the en- gine is running too fast or slow, take your generator to a Authorized Sears Service Center for repair and adjust- ment.

Low engine speeds impose a heavy load on the engine and when sufficient power is not available the engine

life could be shortened.
