MAINTENANCE
G)
CLEAN COOLING SYSTEM frequently, by removing any
build-up of grass, dirt or other debris from the cylinder and
cylinder head COOLING FINS, AIR INTAKE SCREEN and carburetor governor LEVERS AND LINKAGE. This will help insure
adequate cooling and correct engine speed and will reduce the
possibility of overheating and mechanical damage.
CHECK OIL LEVEL REGULARLY.
another free manual from www.searstractormanuals.com
POSITION EQUIPMENT SO ENGINE IS LEVEL.
Check level every five (5) operating hours or each time equipment is used. Always clean area around OIL FILL PLUG (see
Figure 1) before removing plug, to avoid contaminating oil with
dirt, grass clippings, etc. Add oil as necessary. DO NOT RUN
ENGINE UNLESS PROPER OIL LEVEL IS MAINTAINED.
LEVEL MUST BE BETWEEN "FULL" AND "ADD" MARK ON
DIPSTICK. See Instructions ® and ® in preceding "PRESTART INSTRUCTIONS" (Page 1).
®
®
Clean every 4 to 8 hours. Proceed as follows:
1. Remove and tap lightly.
2. Knead with hands to remove any remaining dirt. Air pressure
may also be used, if available.
®
CHANGE OIL - after first two (2) hours of operation and
every twenty-five (25) hours thereafter, or more often if
operated in extremely dusty or dirty areas.
DRAIN OIL - Position equipment so that engine OIL DRAIN
PLUG (see Figure 1l is lowest point on engine. Remove OIL
DRAIN PLUG and OIL FILL PLUG (while engine is still warm)
and allow oil to drain completely.
®
INTAKE AIR FILTER (see Figure 1)
3. Replace on engine.
SPARK PLUG (see Figure 1)
Clean and reset gap periodically. Clean area around SPARK
PLUG base, prior to removal, to prevent dirt from entering
engine. Replace SPARK PLUG if electrodes are pitted or burned
or if porcelain is cracked. Clean SPARK PLUG by carefully
scraping electrodes (do not wire brush or sand blast). Be sure
entire SPARK PLUG is clean and free of foreign material. Check
electrodes gap with wire feeler gauge and reset gap to .030 if
necessary. If replacing SPARK PLUG, use Champion J-8 or
J-17LM or equivalent (see note below) and tighten to 15 foot
pounds or if lacking torque wrench tighten firmly.
Replace OIL DRAIN PLUG and tighten securely. Refill oil sump
with new oil of proper viscosity and service classification per
preceding "OIL & FUEL RECOMMENDATIONS" (Page 1).
Replace OIL FILL PLUG and tighten securely. See Instructions
®and@ in preceding "PRE-START INSTRUCTIONS" (Page
1).
NOTE: If your engine is equipped with a Champion RJ-17LM
resistor spark plug, it is in compliance with the Radio Noise
Limitations Order (Radio Frequency Interference) issued by the

NEVER STORE ENGINE WITH FUEL ~N TANK INDOORS
OR IN ENCL.OS£0, POORLY VENTilATED ENCLOSURES.
WHERE FUEL FUMES M A Y REACH AN OPEN FlAM£,
DO NOT MAKE UNNECESSARY ADJUSTMENTS. FACTORY SETTINGS ARE SATISFACTORY FOR MOST APPLICATIONS AND
CONDITIONS. IF ADJUSTMENTS ARE NEEDED, PROCEED AS
FOLLOWS:
_J)
If engine is to be un-used for 30 days or more, prepare as follows:
A. HIGH SPEED ADJUST NEEDLE is pre-set at the factory.
(1-1/2 turns open) Re-adjustment should not be necessary.
B. Close IDLE ADJUST NEEDLE by turning clockwise. Close
finger tight only. Forcing may cause damage.
C. Open IDLE ADJUST NEEDLE by turning 1-1/4 turns
counterclockwise.

A
A. Run engine until FUEL TANK is empty and engine stops due
to lack of fuel.
D. Start engine. Follow preceding STARTING INSTRUCTIONS. Run engine a few minutes to warm it up.
B. Disconnect FUEL LINE at CARBURETOR or FUEL TANK.
Be very careful not to damage FUEL LINE, Fittings or FUEL
TANK.
Drain any remaining fuel from System
E. With engine running at IDLE speed, adjust IDLE ADJUST
NEEDLE 1/8 turn at a time, clockwise and counterclockwise,
until engine runs smoothly.
®
Remove all gasoline from CARBURETOR and FUEL TANK to
prevent gum deposits from forming on these parts and causing
possible malfunction of engine.
Allow several seconds between each adjustment for engine
to adapt to new setting.
®
NEVER TAMPER WfTH £NGJNE GOVERNOR WHICH lS
FACTORY SET FOR PROPER ENGINE SPEED. OVERSPEEDING ENGINE ABOVE FACTORY HIGH SPEED
SETTING CAN BE DANGEROUS.
®
FOR ANY MAJOR ADJUSTMENTS OR REPAIRS, CONTACT
YOUR NEAREST SEARS ROEBUCK AND CO. (OR
SIMPSONS-SEARS LIMITED) SERVICE CENTER.
h AVOID SPRAY . FROM $PARK PlUG HOLE WHEN
. . CRANKING ENGINE OVER' SLOWtY;
If oil has not been changed recently, this may be a good time to
do it. See "CHANGE OIL" instructions in "MAINTENANCE"
section.
Remove SPARK PLUG and pour one (1) ounce (0,029 Liter) of
engine oil into spark plug hole. Crank engine over, slowly,
several times.
Replace SPARK PLUG.
Clean engine by removing 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 plug and ignition points is made necessary by NORMAL use.
Professional Air-Cooled Engine Service is as close as your nearest
Sears Roebuck and Co. (or Simpsons-Sears Limited) Service Center.
A yearly check-up or tune-up by Sears is a good idea to avoid
breakdowns or delay ... do it at the end of the season, then you're
ready for the next. We even prepare it for storage for you.
