Some engines may be equipped with an anti-icing air cleaner feature
to enable the engine torunat temperatures below 32OF(0°C), without
ice forming in the carburetor.
Ifso equipped, the air cleaner base will have an opening which draws
warm air from the muffler into the air cleaner housing. To work
effectively, it is necessary to block cold air from entering the air
cleaner.
IN TEMPERATURES 32°F (0°C) AND BELOW: (See figure 6)
1. Remove wing nut from air cleaner cover.
2. Remove air cleaner cover from base.
3. Remove red baffle from inside of aircleaner cover,
4. insert red baffle in "winter" position shown.

ADJUSTMENTS STORAGE
DO NOT MAKE UNNECESSARY ADJUSTMENTS. FACTORY SET- _k,
TINGS ARE SATISFACTORY FOR MOST APPLICATIONS AND
CONDITIONS. IF ADJUSTMENTS ARE NEEDED, PROCEED AS
FOLLOWS:
(_) CARBURETOR
If you think your carburetor needs adjusting, see your nearest SEARS,
ROEBUCK AND CO. (OR SEARS CANADA, INC.) SERVICE CENTER.
Engine performance should not be affected at altitudes up to7,000 feet. For
operation at higher elevations, contact your nearest SEARS, ROEBUCK
AND CO, ( OR SEARS CANADA, INC.) SERVICE CENTER.
(_) REMOTE CONTROL (see Figure 6):
For satisfactoryengine performance, engine and equipment controlmust be
adjusted properly. To check engine control adjustments, proceed as
follows:
A. Set equipment control at "FAST" or"HIGH SPEED" and keep itin this
position.
The engine controllever should touch"HIGH SPEED STOP". Ifit does,
the controls are adjusted correctly and no adjustment is necessary.
NOTE: Ifengine controllever does not touch "HIGH SPEED STOP",
proceed to instruction "B'.
B. Loosen clamp screw so remote control cable can be moved in cable
clamp.
C, Move engine control lever so it is touching "HIGH SPEED STOP" and
hold in this position.
D. Tighten clamp screw securely so cable cJamp will hold remote control
cable in place when equipment control is used.
The engine controls should now be adjusted correctly. If additional
adjustments are needed, make them at the equipment control (see
equipment manufacturer's instructions).
NEVER STORE ENGINE WITH FUEL IN TANK INDOORS OR
IN ENCLOSED, POORLY VENTILATED AREAS, WHERE FUEL I
FUMES MAY REACH AN OPEN FLAME, SPARK OR PILOT I
LIGHT AS ON A FURNACE, WATER HEATER, CLOTHES
DRYER OR OTHER GAS APPL ANCE. j
IF ENGINE IS TO BE UNUSED FOR 30 DAYS OR MORE,
PREPARE AS FOLLOWS:
(_) DRAIN FUEL SYSTEM:
Remove all gasoline from carburetor and fuel tank to prevent gum
deposits from forming on these parts and causing possible malfunction
ofen@ine.
,_ DRAIN FUELINTOAPPROVED CONTAINER OUTDOORS AWAY I
FROM OPEN FLAME. BE SURE ENGIN EIS COOL. DO NOT SMOKE.
Run engine until fuel tank isempty and engine stops due to lack of fuel.
NOTE: If"Gasohol" has been used, complete above instructionand
then put 1/2 pint of gasoline intofuel tank and repeat above
instructions.
NOTE:
Fuel stabilizer (suchas STA-BIL) is an acceptable alternative
in minimizing the formation of fuel gum deposits during
storage. Add stabilizer to gasoline in fuel tank or storage
container. Always follow mix ratio found on stabilizer contain-
er. Run engine at least 10 minutes after adding stabilizer to
allow itto reach carburetor.
CHANGE OIL:
Change oil if it has not been changed in the last three (3) months. See
"CHANGE OIL" instructions in "MAINTENANCE" section on Page 3.
HIGH SPEED POSITION
(_) OIL CYLINDER BORE:
A. Remove spark plug. Squirt one (1) oz. (30 ml) of clean engine oil into
spark plug hole.
B. Crank engine over, slowly, several times.
_k AVOID SPRAY FROM SPARK PLUG HOLE WHEN CRANKING
ENGINE OVER SLOWLY.
C. Replacesparkplug.

(_ CLEAN ENGINE:
Remove any clippings, dirt, or chaff from exterior of engine.
GENERAL
Just as your automobile needs professional mechanical maintenance from time
to time, so does your Craftsman engine. Replacement of the spark plugand air
cleaner is made necessary by NORMAL use. Professional Air-Cooled Engine
Service isas close as your nearest Sears Roebuck and Co. (or Sears Canada,
Inc.) Service Center.
A yearly check-up or tune-up by Sears is a good idea to avoid breakdowns or
delay.., do itat the end ofthe season, then you're ready for the next. We even
prepare it for storage for you.
