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 SAE 30 OIL.

Tecumseh specially formulated oil is available at any Autho­rized Tecumseh Service Outlet. Order as part number 730225.

Using multigrade oil will increase oil consumption.

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.

(SAE 10W is an acceptable substitute.)
(BELOW 00F; -180C ONLY): SAE 0W30 is an acceptable

substitute.

DO NOT USE SAE 10W40 OIL.
OIL SUMP CAPACITY: 21 ounces (1-1/4 U.S. pints)

.62 liter

Á Á A FRESH, CLEAN, UNLEADED REGULAR,

UNLEADED PREMIUM OR REFORMULATED
AUTOMOTIVE GASOLINE ONLY. DO NOT USE
LEADED GASOLINE.

NOTE: DO NOT USE GASOLINE CONTAINING METHANOL

(WOOD ALCOHOL). Gasoline containing up to 10%
ethanol or grain alcohol (“Gasohol”), or up to 15 MTBE
(Methyl Tertiary Butyl Ether), may be used but
requires special care when engine is unused for
extended periods.

See “STORAGE” instructions on Page 5.

NOTE: Use clean oil and fuel and store in approved, clean,

covered containers. Use clean fill funnels.
Never use “stale” gasoline left over from last season

or stored for long periods.

BEFORE STARTING

ÀÀ READ ALL INSTRUCTIONS PROVIDED WITH THE EQUIP-

MENT ON WHICH THIS ENGINE IS USED.

BEFORE STARTING (Continued)

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:

- Ignition switch on engine or equipment is in “ON”,
“RUN” or “START” position.

OR

- Ignition key (if so equipped see Figure 2) is inserted
into ignition keyslot in carburetor cover (see Figure 1).

DO NOT TURN IGNITION KEY.

D. Be sure fuel valve is open (see Figure 3).

ENGINE WILL NOT START
UNLESS IGNITION KEY IS
INSERTED INTO IGNITION
KEYSLOT IN CARBURTER
COVER.

DO NOT TURN IGNITION KEY

ÁÁ TO 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.

- Oil fill plug is tightened securely into oil fill tube or hole.

CHECK OIL LEVEL OFTEN DURING ENGINE BREAK-IN.

A. POSITION EQUIPMENT SO ENGINE IS LEVEL.
B. Clean area around oil fill plug (see Figure 1).
C. Remove oil fill plug and dipstick.
D. 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.

E. Install oil fill plug and dipstick, tighten securely.

NEVER RUN ENGINE INDOORS OR IN ENCLOSED,
POORLY VENTILATED AREAS. ENGINE EXHAUST
CONTAINS CARBON MONOXIDE, AN ODORLESS AND
DEADLY GAS (CARBON MONOXIDE IS ALSO PRESENT IN
ENGINE EXHAUST FROM LIQUID PETROLEUM (LPG) AND
NATURAL GAS FUEL SYSTEMS).

KEEP HANDS, FEET, HAIR AND LOOSE CLOTHING AWAY
FROM ANY MOVING PARTS ON ENGINE AND EQUIP­MENT. NEVER LEAVE EQUIPMENT UNATTENDED WHEN
ENGINE IS OPERATING.

WARNING - TEMPERATURE OF MUFFLER AND NEARBY
AREAS MAY EXCEED 1500F (650C). AVOID THESE AREAS.

ÀÀ RECOIL STARTER (see Figure 1):

A. Move equipment control (see equipment manufacturer’s

instructions) or engine control lever to “FAST” or “START”
position.

B. Move engine choke to “FULL”.

NOTE: IF RESTARTING A WARM ENGINE AFTER A

SHORT SHUTDOWN:

1. MOVE CHOKE TO “OFF” INSTEAD OF “FULL”.

2. DO NOT USE PRIMER.

C. Push primer three (3) times (see Figure 4). Always cover

vent hole when pushing primer. See warm engine restart
“NOTE” above.

D. Grasp starter handle (see Figure 1) and pull rope out,

slowly, until it pulls slightly harder. Let rope rewind slowly.
Then pull rope with a rapid full arm stroke. Let rope return
to starter slowly.

NOTE: If RECOIL STARTER is frozen and will not crank

engine, proceed as follows:

1.Pull as much rope out of starter as possible.

2.Release starter handle and let it snap back
against starter.

NOTE: The above should be done only when necessary

to free a frozen starter.

E. If engine fails to start after 3 pulls, repeat instructions C - E

as necessary, until engine starts.
F. When engine starts, move choke gradually to “OFF”.
G. If engine falters, move choke immediately to “FULL” and

ÁÁ ELECTRIC STARTER (see Figure 5)

WARNING: THE 120V A.C. STARTER IS EQUIPPED WITH A THREE­WIRE POWER CORD AND PLUG, AND IS DESIGNED TO OPERATE
ON 120V A.C. HOUSEHOLD CURRENT. THE STARTER MUST BE
PROPERLY GROUNDED AT ALL TIMES TO AVOID THE POSSIBILITY
OF INJURY OR DEATH FROM ELECTRICAL SHOCK. DETERMINE
THAT YOUR HOUSE WIRING IS A GROUND FAULT INTERRUPTED
(G.F.I.) THREE-WIRE GROUNDED SYSTEM, OR ASK A LICENSED
ELECTRICIAN IF YOUR ARE NOT SURE. IF YOUR HOUSE WIRING
SYSTEM IS NOT A G.F.I. THREE-WIRE GROUNDED SYSTEM, DO NOT
USE THIS ELECTRIC STARTER UNDER ANY CONDITION. IF YOUR
HOUSE WIRING SYSTEM IS GROUNDED BUT A G.F.I. THREE-PRONG
WALL RECEPTACLE IS NOT AVAILABLE AT THE LOCATION YOUR
STARTER WILL BE USED, ONE SHOULD BE INSTALLED BY A
LICENSED ELECTRICIAN.

NOTE: If your engine is equipped with a 12V battery-operated electric

starter, disregard instructions regarding power cord.

A. Connect power cord to switchbox on engine.
B. Plug other end of power cord (see Figure 5) into wall

receptacle.
IMPORTANT: When connecting power cord, always con-

nect power cord to switch box on engine first; then into wall
receptacle.

C. Move equipment control (see equipment manufacturer’s

instructions) or engine control lever to “FAST” or “START”

position.
D. Move engine choke to “FULL”.
E. Push primer three times, making sure to cover vent hole

when pushing (see Figure 4).

NOTE: If restarting a warm engine after a short shutdown:

1. Leave choke in "OFF" position.

2. Push primer one time only.

F. Push starter button (see Figure 5) or turn ignition switch key

(see equipment manufacturer’s instructions) to crank en-

gine.
G. When engine starts, release starter button and move choke

gradually to “OFF”.
H. If engine falters, move choke immediately to “FULL” and then

gradually to “OFF”.
I. Disconnect power cord (see Figure 5) from wall receptacle

first, and then from switchbox on engine.
IMPORTANT: When disconnecting power cord, always unplug

wall receptacle end first; then unplug switchbox on engine.
NOTE: The electric starter is thermally protected. If overheated,

it will stop automatically and can be restarted only when
it has cooled to a safe temperature (a wait of approxi­mately 5-10 minutes is required).

If, after following the preceding instructions, the engine does not
