OPERATION

ADD GASOLINE 

•  Fill fuel tank to bottom of filler neck. Do not overfill.  

Use fresh, clean, regular un lead ed gasoline with a 

minimum of 87 octane.  (Use of  leaded gasoline will 

increase carbon and lead oxide deposits and reduce 

valve life).  Do not mix oil with gasoline.  Purchase fuel 

in quan ti ties that can be used within 30 days to assure 

fuel freshness.

CAUTION:  Fill to within 1/2 inch of top 

of fuel tank to prevent spills and to 

allow for fuel expansion.  If gasoline 

is ac ci den tal ly spilled, move machine 

away from area of spill.  Avoid creating 

any source of ignition until gasoline 

vapors have disappeared.  
Wipe off any spilled oil or fuel.  Do not 

store, spill or use gasoline near an 

open flame.

IMPORTANT:

  WHEN OPERATING IN TEMPERATURES 

BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE 

GAS O LINE TO HELP INSURE GOOD COLD WEATHER 

START ING.

IMPORTANT

:   BE VERY CAREFUL NOT TO ALLOW DIRT 

TO ENTER THE ENGINE WHEN CHECKING OR ADDING 

OIL OR FUEL.  USE CLEAN OIL AND FUEL AND STORE IN 

AP PROVED, CLEAN, COVERED CONTAINERS.  USE CLEAN 

FILL FUNNELS.

FILL ENGINE WITH OIL (See Fig. 7)

•  With engine level, remove engine oil filler plug.
• 

Fill engine with oil to point of overflowing.  For ap proxi-

 mate ca pac i ty see “PRODUCT SPEC I FI CA TIONS” on 

page 3 of this manual.

•  Tilt tiller back on its wheels and then re-level.
• 

With engine level, refill to point of overflowing if nec es-

 sary.  Re place oil filler plug.

•  For cold weather operation you should change oil for 

easier starting (See  “OIL VISCOSITY CHART” in the 

Maintenance section of this manual).

•  To change engine oil, see the Maintenance section of 

this manual.

CAUTION:  Alcohol blended fuels (called gas o hol 

or using ethanol or methanol) can attract mois-

ture which leads to sep a ra tion and for ma tion of 

acids during storage.  Acidic gas can damage 

the fuel system of an engine while in storage.  To 

avoid engine problems, the fuel system should 

be emptied before stor age of 30 days or longer.  

Drain the gas tank, start the engine and let it run 

until the fuel lines and carburetor are empty.  Use 

fresh fuel next sea son.  See Storage In struc tions 

for additional information.  Never use engine or 

carburetor cleaner products in the fuel tank or 

permanent damage may occur.

TO START ENGINE (See Fig. 8)

CAUTION:  Keep drive control bar in 

“DISENGAGED” position when start-

 ing en gine.

When starting engine for the first time or if engine has run 

out  of fuel, it will take extra pulls of the recoil starter to 

move fuel from the tank to the engine.
•  Make sure spark plug wire is prop er ly connected.
•  Place throttle control in “FAST” position.
•  Turn fuel shut-off valve 1/4 turn to open position.
•  Move choke control to choke position.
•  Grasp recoil starter handle with one hand and grasp 

tiller handle with other hand.  Pull rope out slowly until 

engine reaches start of com pres sion cycle (rope will 

pull slightly harder at this point).

•  Pull recoil starter handle quickly.  Do not let starter 

handle snap back against starter.

•  If engine fires but does not start, move choke control 

to half choke position. Pull recoil starter handle until 

engine starts.

•  When engine starts, slowly move choke control to 

"RUN" position as engine warms up.

NOTE

:  A warm engine requires less choking to start.

•  Move throttle control to desired running position.
•  Allow engine to warm up for a few minutes before 

engaging tines.

NOTE

:  If at a high altitude (3000 feet) or in cold 

temperatures (below 32°F), the carburetor fuel mixture 

may need to be adjusted for best engine performance. 

See "TO ADJUST CARBURETOR" in the Service and 

Adjustments section of this manual.

NOTE

:  If engine does not start, see troubleshooting 

points.
