menL Do not attempt to change engine speed. If you believe the engine Is running too fast or too slow, take your generator to an authorized Sears Service Center for repair and adjustment. CHANG_

ING ENGINE GOVERNED SPEED WILL VOID EN- GINE WARRANTY.

Th speed of the generator is maintained by an electronically controlled governor. DO NOT try to adjust the governed speed setting for the following reasons:

•High engine speeds are dangerous and increase the risk of personal injury or damage to equipment.

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

°The generator will supply correct rated AC frequency and voltage only at the proper speed Some connected electrical devices could be damaged by incorrect fre- quency and/or voltage

CARBURETOR

You may need to adjust the carburetor to compensate for' differences in fuel, temperature, altitude or load Air cleaner and air cleaner cover must be assembled to carbu-

retor when you run the engine

NOTE: DO NOT remove the air cleaner when running the

engine Operation without the air cleaner fully assembled and the air filter installed may cause engine damage

INITIAL ADJUSTMENT

°Gently turn IDLE MIXTURE valve (Fig 20) clockwise until it just closes DO NOT FORCE Valve may be damaged by turning it inward too far

,,Next open IDLE MIXTURE valve 1-3/4 turns counter- clock,vise

=This initial adjustment will permit the engine to be started and warmed up

FINAL ADJUSTMENT

,,Start engine and let it warm up for at least five minutes

,Hold the throttle against its idle stop (idle speed) and then turn the IDLE MIXTURE vaive slowly clockwise 1/8 turn at a time until the lean dropoff point is reached

(engine starts to miss and run erratically) Now turn the IDLE MIXTURE valve counterc!ockwise until engine speed begins to s!ow again (rich dropoff point)

•Turn the valve to mid point between rich and lean

tf further adjustment is needed, the main adjustment should be made under a load condition as outlined under LOAD

ADJUSTMENT

LOAD ADJUSTMENT

•Let engine accelerate to normal governed speed.

•Apply electrical loads to the generator at or near the unit'sfull rated wattage/amperage capacity.

•If the engine stops or hesitates under load, open the IDLE MIXTURE screw 1/8 turn at a time. Test each

setting with the engine under load until engine runs smoothly.

=If engine smokes excessively, turn the IDLE MIXTURE SCREW clockwise 1/8 turn at a time until condition is corrected

•After IDLE MIXTURE SCREW is properly set, move throttle to idle speed position. If engine does not idle smoothly turn IDLE SPEED SCREW 1/8 turn at a time (either direction) until engine runs smoothly

NOTE: Engines operated at altitudes at about 5000 feet or higher may require that you install a high altitude carburetor main jet (Part No 80883) to achieve best engine perform- ance If engine performs erratically, contact your Sears Service Center to install the high altitude jet
