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.

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.

FIG. 7

TO START ENGINE (See Fig. 8)

CAUTION:  Keep tine control in “OFF” 
position when starting engine.

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.

• 

Move choke control to full “CHOKE” position. Grasp 
recoil starter handle with one hand and grasp tiller 
handle with other hand.  Pull rope out slowly until en-
gine 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.  Repeat if necessary.

• 

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.

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.
