ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
All engines contain carbon monoxide in their exhaust. Carbon monoxide is a deadly, colorless, tasteless, odorless gas
which may be present even if you do not smell or see any engine exhaust. Levels of carbon monoxide, which can be
deadly, can be present for days in an enclosed area that has poor ventilation. Any level of carbon monoxide, if
inhaled, can cause headaches, drowsiness, nausea, dizziness, confusion and eventually death. If you experience any of
these symptoms, seek fresh air and medical attention immediately.
Preventing Carbon Monoxide Poisoning
Never run engine indoors.
•Never try to ventilate engine exhaust indoors. Carbon monoxide can reach dangerous levels very quickly.
•Never run engine outdoors where exhaust fumes may be pulled into a building.
•Never run engine outdoors in a poorly ventilated area where the exhaust fumes may be trapped and not easily taken
away. (Examples include: in a large hole or areas where hills surround your working area.)
•Never run engine in an enclosed or partially enclosed area. (Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
•Always run the engine with the exhaust and muffler pointed in the direction away from the operator.
•Never point the exhaust muffler towards anyone. People should always be many feet away from the operation of
the
engine and its attachments.
Gasoline Fires and Handling Fuel Safely
Fuel and fuel vapors are highly flammable. Never use fuel where a spark or flame may be present. Never use fuel where
a potential source of ignition could occur. (Examples include: hot water or space heaters, clothes dryer, electric motors, etc.)
Keep flames and sparks away from engine and fuel to prevent fires. Fuel fires spread very quickly and are highly
explosive.
Prevention of Gasoline Fires
•Never fill your fuel tank indoors. (Examples include: basement, garage, barn, shed, house, porch, etc.)
Always fill fuel tank outside in a well-ventilated area.
•Never remove the fuel cap or add fuel with the engine running. Stop engine and allow to cool before filling.
•Never drain fuel from engine in an enclosed area.
•Always wipe up excess (spilled) fuel from engine before starting. Clean up spilled fuel immediately.
•Allow spilled fuel to dry, after wiping and before starting.
•Allow fuel fumes/vapors to escape from the area before starting engine.
•Test the fuel cap for proper installation before starting and using engine.
•Always run the engine with fuel cap properly installed on the engine.
•Always unscrew gas cap vent screw while engine is running.
•Never smoke while refilling engine fuel tank.

!
!
6!
•Prevent fire and explosion caused by static electric discharge. Use only nonmetal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the American Society for Testing & Materials (ASTM).
•Do not store engine with fuel in fuel tank indoors. Fuel and fuel vapors are highly explosive.
•During storage, screw down gas cap vent screw tightly.
•Never pour fuel from engine fuel tank.
•Never siphon fuel by mouth to drain fuel tank.
•Always have an adult fill the fuel tank.
•Never allow an adult or anyone under the influence of drugs or alcohol to fill engine.
•Never allow children to fill the engine.
•The clutch will transfer maximum power after about two hours of normal operation. During this break-in period clutch
slippage may occur. The clutch should be kept free of oil or other moisture for efficient operation.
BURNS AND FIRES
The muffler, muffler guard and other parts of the engine become extremely hot during the operation of the engine.
These parts remain extremely hot after the engine has stopped. Do not touch.
Prevention of Burns and Fires
•Never remove the muffler guard from the engine.
•Never touch the muffler guard because it is extremely
hot and will cause severe burns.
•Never the engine that becomes hot after operation.
•Always keep materials and debris away from muffler
guard and other hot parts of the engine to avoid fires.
This engine is designed to operate using a catalytic
converter which contributes to the engine’s compliance
with the EPA.
Steps for Working on Engine or Cultivator
1. Turn off engine switch.
2. Disconnect the spark plug wire from the spark plug.
3. Securely place the disconnected spark plug wire
away from the spark plug and any metal parts. This
must always be done or arcing may occur between
spark plug wire and metal parts.
4. Replace or repair the part on the engine or cultivator.
5. Check all parts that were repaired, or removed during
repair, that they are secure and fit correctly.
NOTE: All repair parts must come from the

NORMAL OPERATION
1. The clutch will transfer maximum power after about two
hours of normal operation. During this break-in period
clutch slippage may occur. The clutch should be kept
free of oil and other moisture for efficient operation.
2. Cultivate without placing excessive body weight on
the unit. The cultivator operates most efficiently with
the weight of the unit itself.
3. Never run engine indoors. Exhaust fumes are deadly.
Using the Screw Type, manual venting Gas Cap
Your cultivator is equipped with a screw type, manual
venting gas cap.
1. Before starting the engine, turn the screw in the top of
the gas cap 2-3 turns (counterclockwise) to its venting
position. DO NOT turn the screw to the point that it stops
(4-5 turns counterclockwise). Check that the gas cap is
screwed on tightly and the gas cap screw is in the
venting position.
2. After using the cultivator and before putting away or
transporting it in a truck bed, screw the gas cap screw
and gas cap on (clockwise) tightly. This will prevent gas
from leaking during storage. The gas cap will not leak
during storage if gas cap is tight and the screw at the
top is tight.
STARTING AND STOPPING ENGINE
•Move engine to a well ventilated area, outdoors, to
prevent carbon monoxide poisoning.
•Move to an area away from flames or sparks, to avoid
ignition of vapors if present.
•Remove all debris from air cleaner holes and gas cap
to ensure proper air flow.
COLD ENGINE START: Starting engine for first time
or after engine has cooled off or after running out of fuel.

Adjusting Wheels and Drag Stake
The wheels on the cultivator can be adjusted to one
of
three positions. The lowest wheel position is used
for
transporting the cultivator across a smooth level
surface while the engine is not running. The two
higher positions are used when cultivating in soil
and help stabilize the unit when cultivating at
different depths.
To adjust wheels up or down:
1. Pull the locking metal sleeve against the spring
until it releases from one of the three holes in
the vertical guide.
2. Slide the wheel set up or down to the desired
position, and release the locking metal sleeve
until it locks into one of the three holes in the
vertical guide.
The drag stake is used to help regulate cultivating
depth and control the cultivator from leaping
forward during operation. Resistance to forward
motion is greatest when the drag stake is set in its
lowest position allowing for deeper cultivation.
To adjust the drag stake:
1. Pull the pin out of the drag stake mount hole.
2. Position the drag stake so the pointed tip is
directed downward.
3. Insert the pin into the hole that achieves
desired depth.
