Operating Precautions
READ, UNDERSTAND AND FOLLOW ALL OF THE
PRECAUTIONS BELOW.
Always perform the pre-start checklist before starting the engine.
• Never operate the tiller without safety shields in place.
• Keep hands, feet, and clothing away from rotating parts. Keep clear
of tiller tines at all times.
• Tines rotate when the engine is running and clutch lever is depressed
(pulled towards the handlebars). Releasing the clutch lever stops the tines.
• Use extreme caution when operating on or crossing gravel drives,
walks, or roads. Stay alert for hidden hazards or trac.
• After striking an obstacle, stop the engine, remove the wire from the
spark plug, inspect the tiller for damage and repair before restarting.
• If tines become clogged, stop the engine and disconnect the spark
plug wire before removing any obstruction.
• Engine muer will be hot from operation. Do not touch it with bare
skin or a severe burn may result.
• If the unit vibrates abnormally, stop the engine and check immediately
for the cause. Vibration is an indication of a potential problem.
• Do not run the engine indoors; exhaust fumes are deadly.
• Do not overload the tiller by trying to till too deep or too fast.
• Never operate the machine at high transport speeds on slippery
surfaces. Look behind and use care when backing.
• Use only attachments and accessories approved by the manufacturer.
• Never operate the tiller without good visibility or adequate light.
• Be careful when tilling in hard ground. e tines may catch in the
ground and propel the tiller. If this occurs, let go of the handlebars and do
not restrain the machine.
• Take precautions when leaving the machine unattended. Disengage
all control levers, stop the engine, wait for all moving parts to stop, and
make certain guards and shields are in place.

Operating Instructions
Preparation for Operation
THIS UNIT WAS SHIPPED WITHOUT OIL IN THE
ENGINE. Check the oil level before each operation.
Fill Engine with Oil
1. Add oil according to engine manual. Do not overll. Use
SAE30 engine oil. Do not mix oil with gasoline. Oil level
must be full. Check the oil level by removing oil ll plug
(see Figure 5). Oil level should be up to the bottom of the
ll plug opening.
Pre-Start Inspection
1. Make sure safety shields are in place and nuts & bolts are
secure.
2. Check oil level.
3. Inspect air cleaner. Clean or replace it as needed.
4. Check fuel supply. Fill the fuel tank no closer than 1 inch
from top of tank to provide space for expansion.
5. Be sure spark plug wire is attached and is tightened securely.
6. Examine underneath and around engine for oil or fuel leaks.
7. Inspect fuel hoses for tightness and fuel seepage.
8. Look for signs of engine damage.
9. Remove excessive debris from muer area and recoil starter.
Adjusting the Depth Regulator
NOTE: e depth regulator is shipped upside down.
e depth regulator determines the depth of the cultivating
blades. Adjust according to the desired working depth. Soil
types that are very hard may require using the cultivator in
several passes, going in dierent directions with the depth
regulator set at deepest position to ensure the soil has been
properly worked through. (Figure 6)

Operating Instructions
NEVER FILL THE FUEL TANK ON A HOT ENGINE
Start-Up
1. Turn the Engine ON/OFF switch to ON (see Figure 7).
2. Slide the fuel shuto lever to the right (open) position
(Figure 8).
Cold Starts
1. Move choke lever all the way to the left (full choke) position.
2. Move throttle lever on handlebar downward to “start”.
3. Pull recoil handle out slowly one time and allow to return.
4. Pull recoil handle out rapidly, and allow rope to return normally.
5. When engine starts, gradually move choke lever to the right (no
choke) position and increase throttle speed.
Restarting A Warm Engine
Restarting an engine that is already warm from previous running
does not normally require use of the choke.
1. Move throttle lever to “start” position.
2. Pull recoil handle out rapidly until engine starts. Allow recoil rope
to return normally. Repeat until engine starts.
3. Adjust throttle speed to “full” for best tiller action.
Idle Speed
Use the “low” position on the throttle lever to reduce stress on the
engine when tilling is not being performed. Lowering the engine
speed to “idle” will help extend the life of the motor, as well as
conserve fuel and reduce the noise level of the equipment.
Operating Speed
For normal tilling, set the throttle lever to full throttle (fast).
Shutting Down
To stop the engine at any time, move throttle control to the STOP
position. To stop tines at any time, release the clutch lever. To
completely shutdown, move the engine ON/OFF switch to OFF
and slide the fuel shuto lever to the closed position.

Pulling the clutch lever toward the handlebar engages the tines.
Releasing the clutch lever stops the tines (see Figure 9).
Tilling Tips
e key to successful tilling is to begin with a shallow cut on the rst
pass, and then work an inch or two deeper on each successive pass.
• Tilling depth will vary with ground conditions.
• When beginning to till in unbroken ground or in extremely hard
soil perform shallow tilling rst then do a second pass going deeper
into the soil.
• Hold on rmly to the handlebars to control sudden lurches.
Immediately release the clutch lever if the tines jam or you strike
a foreign object. With the clutch lever released, push the throttle
control to stop position to stop the engine. When tines have
stopped, disengage the spark plug wire, then remove foreign objects.
