SAFETY RULES
SAFE OPERATION PRACTICES FOR WALK-BEHIND POWERED ROTARY TILLERS
TRAINING
• Read the Owner’s Manual carefully. Be thoroughly
familiar with the controls and the proper use of the
equipment. Know how to stop the unit and disengage the
controls quickly.
• Never allow children to operate the equipment. Never
allow adults to operate the equipment without proper
instruction.
• Keep the area of operation clear of all persons, particularly small children, and pets.
PREPARATION
• Thoroughly inspect the area where the equipment is to
be used and remove all foreign objects.
• Disengage all clutches and shift into neutral before
starting the engine (motor).
• Do not operate the equipment without wearing adequate
outer garments. Wear footwear that will improve footing
on slippery surfaces.
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.

TILLING
The speed and depth of tilling is regulated by the position of
the depth stake and wheel height.
The depth stake should always be below the wheels for
digging. It serves as a brake to slow the tiller’s forward
motion to enable the tines to penetrate the ground. Also, the
more the depth stake is lowered into the ground the deeper
the tines will dig.
DEPTH STAKE (See Fig. 6)
Adjust depth stake by removing the hairpin clip and clevis
pin. Change depth stake to desired position. Replace the
clevis pin and hairpin clip.
• For normal tilling, set depth stake at the second or third
hole from the top.
WHEELS (See Fig. 6)
Adjust wheels by removing the hairpin clip and clevis pin.
Change wheel position. Replace the hairpin clip and clevis
pin.
• For normal tilling, set wheels at the second or third hole
from the top.

ADD GASOLINE
• Fill fuel tank. Use fresh, clean, regular unleaded
gasoline. (Use of leaded gasoline will increase carbon
and lead oxide deposits and reduce valve life.)
IMPORTANT: WHEN OPERATING IN TEMPERATURES
BELOW 32°F (0°C), USE FRESH, CLEAN, WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
WARNING: Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation 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 storage 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 season. See Storage section of this manual for
additional information. Never use engine or carburetor
cleaner products in the fuel tank or permanent damage may
occur.
CAUTION: Fill to within 1/2 inch of top
of fuel tank to prevent spills and to allow
for fuel expansion. If gasoline is accidentally spilled, move machine away
from area of spill. Avoid creating any
source of ignition until gasoline vapors
have disappeared.
Do not overfill. Wipe off any spilled oil
or fuel. Do not store, spill or use gasoline near an open flame.
TO START ENGINE (See Fig. 8)
CAUTION: Keep drive control bar in
“DISENGAGED” 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 properly connected.
• Move shift lever indicator to “N” (neutral) position.
• Place throttle control in “FAST” 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 compression 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.
