Figure 10
Let the engine warm up by running it at a low rpm (slow
speed) for approximately two or three minutes. NOTE:
YOU DO NOT HAVE THE ENGINE UNDER LOAD
DURING THE WARM UP PERIOD.
By moving the throttle lever, increase the engine speed
(rpm) to the required operating rpm before placing the
unit under load (cutting).
ALWAYS reduce the engine speed to idle speed when
not cutting.
CAUTION_
NEVER OPERATE THE ENGINE AT HIGH RPM
WITHOUT LOAD. With throttle fully opened and no
load, the engine rpm wilt be very high which can have an
adverse effect on the life of the engine.
Adjustments
SPARK PLUG MAINTENANCE -- If the spark plug
electrode area has an excess of carbon buildup, the
efficiency of the plug will be seriously reduced.
REMOVE THE CARBON WITH A SPARK PLUG
CLEANER OR WIRE BRUSH.
After cleaning the spark plug RESET THE
ELECTRODE GAP TO 0.6/0.7 MM (.024-.028).
Carburetor
Proper adjustment of the carburetor is very important to
the operation of this engine. The carburetor has been
carefully adjusted at the factory and therefore should
not require any further adjustmefit.
Carburetor Adjustment
Idle speed adjustment is accomplished by turning the
throttle stop screw.
THROTrLE StOP SCRE,Y
Turning the throttle stop screw clockwise will increase
the idle speed. Turning the throttle stop screw counter-
clockwise will decrease the idle speed.
For any additional carburetor adjustments take the
complete unit to the nearest Sears Service Center.
Preventative Maintenance Check List and Storage Tips
Be sure the engine and all other parts are clean.
Check all nuts, bolts, screws, etc. making sure they are
tightened and secured as they should be.
Inspect carefully for any fuel or oil leaks.
Check the air cleaner assembly for excessive dust or dirt.
If the filter requires cleaning, use the following
procedure: Remove the filter and wash in soap and
water or blow off with compressed air. DO NOT clean
filter in gasoline or other flammable solvent.
