TO START ENGINE (See Fig. 8)

CAUTION:  Keep drive control bar in 
“DISENGAGED” position when start-
 ing en gine.

When starting engine for the fi rst 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.
•      Move shift lever indicator to “N” (neutral) position.
•      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 neces-
sary.

•      If engine fi res 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 (above 3000 feet) or in cold 

temperatures (below 32°F), the carburetor fuel mix ture may 
need to be adjusted for best engine per for mance.  See “TO 
ADJUST CARBURETOR” in the Service and Ad just ments 
section of this manual.

NOTE:

  If en 

gine does not start, see trou 

ble shoot ing 

points.

BEFORE STARTING ENGINE

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 fi ller plug.
•      Fill engine with oil to point of overfl owing.  For ap prox-

i 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, refi ll to point of overfl owing if nec-

 es sary.  Re place oil fi ller 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.

ADD GASOLINE 

•     Fill fuel tank to bottom of fi ller neck. Do not overfi ll.  

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 fl ame.

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.

CAUTION:  Alcohol blended fuels (called 
gas o hol or using ethanol or methanol) can at-
tract moisture 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.
