TURNING

•      Release the drive control bar.
•      Move throttle control to “SLOW” position.
•         Place shift lever indicator in “F” (forward) position.  Tines 

will not turn.

•      Lift handle to raise tines out of ground.
•     Swing the handle in the opposite direction you wish 

to turn, being careful to keep feet and legs away from 
tines.

•      When you have completed your turn-around, release 

the drive control bar and lower handle.  Place shift  
lever in till position and move throttle control to de sired 
speed.  To begin tilling, hold drive control bar against 
the handle.

OUTER SIDE SHIELDS (See Fig. 11)

The back edges of the outer side shields are slotted so 
that the shields can be raised for deep tilling and low ered 
for shal low tilling to protect small plants from being buried.  
Loosen nut “A” in slot and nut “B”.  Move shield to desired 
position (both sides).  Retighten nuts.

TO TRANSPORT

CAUTION:  Before lifting or trans port ing, 
allow tiller engine and muffl er to cool.  
Disconnect spark plug wire.  Drain 
gasoline from fuel tank.

AROUND THE YARD

•     Release the depth stake pin.  Move the depth stake 

down  to the top hole  for transporting the tiller.  Place 
depth stake pin in hole of depth stake to lock in posi-
tion.  This prevents tines from scuffi ng the ground.

•     Place shift lever indicator in “F” (forward) position for 

transporting.

•     Hold the drive control bar against the handle to start 

tiller movement.  Tines will not turn.

•      Move throttle control to desired speed.

AROUND TOWN

•      Disconnect spark plug wire.
•      Drain fuel tank.
•      Transport in upright position to prevent oil leakage.

BEFORE START ING 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 
APPROVED, CLEAN, COVERED CONTAINERS.  USE CLEAN 
FILL FUNNELS.

CHECK ENGINE OIL LEVEL (See Fig. 12)

•     

The engine in your unit has been shipped, from the 
factory, already fi lled with SAE 30 summer weight oil.

•      With engine level, clean area around oil fi ller plug and 

remove plug.

•         Engine oil should be to point of overfl owing when engine 

is level.  For ap proxi mate capacity see “PROD UCT 
SPEC I FI CA TIONS” on page 3 of this manual.  All oil 
must meet A.P.I. Service  Classifi cation SF-SJ.

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.
