OIL & FUEL RECOMMENDATIONS
TO OPERATE ENGINE, YOU WILL NEED THE FOLLOWING:
ÀÀ A CLEAN, HIGH QUALITY, DETERGENT OIL.
Be sure original container is marked:
A.P.I. service “SF” - “SJ”.
FOR SUMMER (ABOVE 320F; 00C) USE SAE30 OIL.
Tecumseh specially formulated oil is available at any Authorized
Tecumseh Service Outlet. Order as part number 730225.
FOR WINTER (BELOW 320F; 00C) USE SAE 5W30 OIL.
Tecumseh specially formulated oil is available at any Authorized
Tecumseh Service Outlet. Order as part number 730226.
DO NOT USE SAE 10W40 OIL.
USING MULTIGRADE OIL WILL INCREASE OIL CONSUMP-
TION.
OIL SUMP CAPACITY: 21 ounces (1-1/4 U.S.
pints) .62 liter.
ÁÁ A FRESH, CLEAN, UNLEADED REGULAR, UNLEADED
PREMIUM, OR REFORMULATED AUTOMOTIVE GASOLINE ONLY. DO NOT USE LEADED GASOLINE.

ÀÀ READ ALL INSTRUCTIONS PROVIDED WITH THE
EQUIPMENT ON WHICH THIS ENGINE IS USED.
ÁÁ FILL OIL SUMP OR CHECK OIL LEVEL:
IMPORTANT: To avoid engine damage never run engine unless:
- Oil level is between “FULL” and “ADD” marks on dipstick (if
so equipped).
- Oil level is to overflow point in oil fill hole on engine without a
dipstick.
- Oil fill plug is tightened securely into oil fill tube or hole.
CHECK OIL LEVEL OFTEN DURING ENGINE BREAK-IN.
A. ENGINE WITH DIPSTICK:
1. POSITION EQUIPMENT SO ENGINE IS LEVEL.
2. Clean area around oil fill plug (see Figure 1).
3. Remove oil fill plug and dipstick.
4. Wipe dipstick clean, insert it into oil fill hole and tighten securely,
remove dipstick. If oil is not up to“FULL” mark on dipstick, add recommended oil. POUR SLOWLY. Wipe dipstick clean each time oil
level is checked.
IMPORTANT: DO NOT FILL ABOVE “FULL” MARK ON DIPSTICK.
5. Install oil fill plug and dipstick, tighten securely.
B.ENGINE WITHOUT DIPSTICK:
1. POSITION EQUIPMENT SO ENGINE IS LEVEL.
2. Clean area around oil fill plug (see Figure 1).
3. Remove oil fill plug.
4. If oil level is not up to overflow point in oil fill hole, add recommended
oil. POUR SLOWLY.
5. Install oil fill plug, tighten securely.
See “MAINTENANCE” section for further oil instructions.
ÂÂ FILL FUEL TANK:
A. Clean area around fuel fill cap, remove cap.
B. Add “UNLEADED” regular gasoline, slowly, to fuel tank. Use a funnel
to prevent spillage.
IMPORTANT: NEVER MIX OIL WITH GASOLINE
C. Install fuel fill cap and wipe up any spilled gasoline.
NEVER FILL FUEL TANK INDOORS. NEVER FILL FUEL TANK
WHEN ENGINE IS RUNNING OR HOT. DO NOT SMOKE WHEN
FILLING FUEL TANK.
NEVER FILL FUEL TANK COMPLETELY. FILL TANK TO 1/2'’
BELOW BOTTOM OF FILLER NECK TO PROVIDE SPACE FOR
FUEL EXPANSION. WIPE ANY FUEL SPILLAGE FROM ENGINE
AND EQUIPMENT BEFORE STARTING ENGINE.
ANY LIQUEFIED PETROLEUM (LPG) OR NATURAL GAS FUEL
SYSTEM MUST BE LEAKPROOF AND MEET ALL APPLICABLE
CODES AND REGULATIONS.
ÃÃ CHECK THE FOLLOWING:
A. BE SURE EQUIPMENT IS IN NEUTRAL GEAR WITH CLUTCHES,
BELTS, CHAINS AND SAFETY SWITCHES DISENGAGED. (FOLLOW EQUIPMENT MANUFACTURER’S INSTRUCTIONS.) THIS
SHOULD PLACE ANY SAFETY SWITCHES IN SAFE STARTING
POSITION.
B. Be sure spark plug wire is attached to spark plug (see Figure 1).
C. Be sure any ignition switch and/or control lever on engine or equip-
ment is in “ON”, “RUN” or “START” position.
STARTING
NEVER RUN ENGINE INDOORS OR IN ENCLOSED, POORLY VENTILATED AREAS. ENGINE EXHAUST CONTAINS CARBON MONOXIDE, AN ODORLESS AND DEADLY GAS.
KEEP HANDS, FEET, HAIR AND LOOSE CLOTHING AWAY FROM
ANY MOVING PARTS ON ENGINE AND EQUIPMENT.
WARNING TEMPERATURE OF MUFFLER AND NEARBY AREAS
MAY EXCEED 1500F (650C). AVOID THESE AREAS.
NOTE: See equipment manufacturer’s instructions for control positions
which correspond to engine control positions in Figures 2 and 4.
ÀÀ ENGINE WITH PRIMER
1) Move control lever (figure 2) to “FAST” or “START” (see equipment
manufacturer’s instructions).
2) The carburetor on your engine has been completely adjusted at the
factory. When starting a cold engine, push primer bulb firmly with your
thumb 5 times, allowing primer bulb to return completely to original
position between pushes. Repeat the above for each starter operation as necessary.
NOTE: DO NOT USE PRIMER TO RESTART A WARM ENGINE
AFTER A SHORT SHUTDOWN.
3) Operate mower control to release engine brake.
4)
a) RECOIL STARTERS: Grasp starter handle (figure 3) and pull rope
out slowly until you feel drag. Let rope rewind slowly. Pull rope
with rapid, full arm stroke. Return rope slowly to original position.
NOTE: If engine fails to start after three pulls, repeat steps 2-3
above.
b) ELECTRIC STARTERS: Crank engine.
NOTE: If engine does not start after five seconds of cranking, stop
and repeat steps 2-3 above.
NOTE: If equipped with a snap-in control as shown, no adjustment
is required.

control lever to “FAST” instead of “CHOKE”.
2)
a) RECOIL STARTERS: Grasp starter handle (figure 3) and pull rope
out slowly until you feel drag. Let rope rewind slowly. Pull rope with
rapid, full arm stroke. Return rope slowly to original position.
b) ELECTRIC STARTERS: Operate mower control to release engine
brake; crank engine.
3) When engine starts, move control lever to “FAST” and then to desired
speed in “RUN” range. If engine falters, move control lever to
“CHOKE”, then to “FAST”, then to desired speed in “RUN” range.
NOTE: RECOIL STARTERS: If engine fails to start after three pulls,
move control lever to “FAST” and pull starter rope again.
NOTE: If engine fires, but does not continue to run, move control lever
to “CHOKE” and repeat steps 2-3 until engine starts. Do not crank an
electric starter for more than five seconds each attempt.

STOPPING
ÀÀ See mower manufacturer’s instructions.
ÁÁ AFTER ENGINE IS STOPPED:
A. DISCONNECT SPARK PLUG WIRE FROM SPARK PLUG AND
ATTACH IT TO RETAINING POST (see Figure 5).
B. TURN IGNITION SWITCH KEY (IF SO EQUIPPED) TO “OFF”
POSITION AND REMOVE KEY FROM SWITCH, THIS WILL
REDUCE THE POSSIBILITY OF UNAUTHORIZED STARTING
OF ENGINE WHILE EQUIPMENT IS NOT IN USE.
NEVER STORE ENGINE WITH FUEL IN TANK INDOORS OR IN
ENCLOSED, POORLY VENTILATED AREAS, WHERE FUEL
FUMES MAY REACH AN OPEN FLAME, SPARK OR PILOT
LIGHT AS ON A FURNACE, WATER HEATER, CLOTHES DRYER OR OTHER GAS APPLIANCE.
