5. Squeeze the throttle control and check that it
returns automatically to the idle position.
6. Never leave this machine unattended with the
engine running.
7. Never attempt to make any adjustments while
engine is running, except where specifically recommended in the operator’s manual.
8. To avoid personal injury or property damage u se extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.
a. Use only an approved gasoline container. b. Extinguish all cigarettes, cigars, pipes, and
other sources of ignition. c. Never fuel machine indoors. d. Never remove gas cap or add while the

inside where there is an open flame, spark,
or pilot light (e.g. furnace, water heater,
space heater, clothes dryer, etc.) j. Allow machine to cool at least 5 minutes
before storing.
OPERATION
1. Do not put hands and feet near rotating parts. Contact with the rotating parts can amputate fingers, hands, and feet.
2. Do not operate machine while under the influence of alcohol or drugs.
3. Never operate this machine without good visibility or light. Always be sure of your footing and keep a firm hold on the handles.
4. Keep bystanders, helpers, pets, and children at least 50 feet from the machine while it is in
3
operation. Stop machine if anyone enters the area.
5. Be careful when cultivating in hard ground. The tines may catch in the ground and propel the cultivator forward. If this occurs, let go of the handle and do not restrain the machine.
6. Never operate the machine at high transport speeds on hard or slippery surfaces.
7. Exercise caution to avoid slipping or falling.
8. Look down, behind, and use care when pulling machine towards you.
9. Start the engine according to the instructions found in this manual and keep feet well away from the tines at all times.
10. After striking a foreign object, stop the engine, disconnect the spark plug wire and ground agains t the engine. Thoroughly inspect the machine for any damage. Repair the damage before starting and operating.
11. Disengage all clutch and stop engine before you leave the operating position (behind the handle). Wait until the tines come to a complete stop before unclogging the tines, making any adjustments, or inspections.
12. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless and deadly gas.
13. Muffler and engine become hot and can cause a burn. Do not touch.
14. Use caution when cultivating near fences, buildin gs and underground utilities. Rotating tines can cause property damage or personal injury.
15. Do not overload machine capacity by attempting to cultivate soil to deep or to fast of a rate.
16. If the machine should start making an unusual noise or vibration, stop the engine, disconnect the spark plug wire and ground it against the engine. Inspect thoroughly for damage. Repair any damage before starting and operating.

Oil Fill-Up
Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each use and change the oil regularly. Failure to use the correct oil or using dirty oil can cause premature engine wear and failure. Refer to Maintenance Section.
Use a high-quality SAE 30 weight oil of API (American Petroleum Institute) service class SF, SG, or SH.
NOTE: This unit is shipped without oil in the engine. In order to avoid damage to the unit, put the recommended oil in the crankcase before attempting to start unit.
This unit is shipped with one 3.4 fluid oz. (100ml) bottle of SAE 30 SF, SG, or SH oil.
NOTE: For cold weather operation, temperatures below 40°F (4°C) use a high-quality SAE 10W30 weight oil of API (American Petroleum Institute) service class SF, SG, or SH.
When adding oil, the unit must be laid back in
the horizontal position on a flat surface with the upper handle touching the ground.
See Figure 3.
Wipe up any oil that may have spilled and reinstall the oil fill plug/dipstick.
Gas Fill-Up
Old fuel is the primary reason for the unit not running properly. Be sure to use fresh, clean, and unleaded gasoline. Use fresh fuel (less than 60 days old), when using alcohol-blended fuel.
When adding fuel, unit must be laid back in the horizontal position on a flat surface.
Remove fuel cap and remove the tag from the fuel tank neck. Refer to Figure 4.
WARNING: Use extreme care when han­dling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running. Extinguish cig­arettes, cigars, pipes, and other sources of ignition.
Place spout of gas container into the fill hole on the fuel tank and fill tank.
Wipe up any gasoline that may have spilled and reinstall the fuel cap.
Move the unit at least 30 ft. (9.1m) from the fueling source and site before starting the engine.

Start the engine referring to Starting Engine.
With both hands on the upper handle and squeezing the throttle control, slowly lower the cultivator until the tines make contact with the ground.
Once the tines are in the ground, continue to cultivate at a moderate pace until you are familiar with the controls and the handling of the cultivator.
To adjust the cultivating depth, adjust the wheel support bracket. See Adjusting The Wheel Bracket.
For cultivation, a two to three inch depth is desirable . When laying out plant rows, be sure to allow enough width to permit cultivation between the rows.

NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by any non-road engine repair estab­lishment, individual or authorized service dealer.
In order to assure peak performance of your engine, inspection of the engine exhaust port may be necessary after 50 hours of operation. If you notice lost RPM, poor performance, or general lack of acceleration, this service may be required. If you feel your engine is need of this inspection, refer to a Sears service center. DO NOT attempt to perform this process yourself as engine damage may result from contaminants envolved in the cleaning process for the port.
WARNING: Always stop engine and dis­connect spark plug wire before cleaning or doing any kind of maintenance on your cultivator / edger.

Remove the oil fill plug/dipstick and check oil level. Oil should be up to the top of the dipstick . Refer to Figure 4.
If the level is low, add a small amount of oil to the oil fill hole and recheck. Repeat until the oil level reaches the top of the dipstick. See Figure 9.
NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick when checking and changing the oil.
WARNING: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crank­case. Never operate the unit with the oil level below the bottom of the dipstick.
Check oil before each use.
Stop engine and allow oil to drain into the crankcase.
When checking oil, the unit must be laid back
in the horizontal position on a flat surface with the upper handle touching the ground.

Rocker Arm Clearance
This requires disassembly of the engine. If you feel unsure or unqualified to perform this adjustment, take the unit to a Sears service center.
NOTE: Insp ect the valve to rocker arm clearance with a feeler gauge after the first 10 hours of operation
10
and then every 50 hours of operation thereafter.
IMPORTANT:
The engine must be cold when checking or adjusting the valve clearance. This task should be performed inside in a clean and dust free area. A new gasket must be used in this adjustment. A new rocker arm gasket (part # 791-182099)can be purchased from your Sears service center.
Remove the muffler cover by pressing down on the
corner with a flat blade screwdriver. Slide the notches on the sides of the muffler cover over the tabs on the engine cover and remove.
Remove the two screws on top of the engine cover
with a phillips screwdriver. See Figure 13.
Screw
Remove the rocker arm cover and gasket. Pull the starter rope slowly to bring the piston to the top of its travel. Make sure:
The piston should be at the top of its travel while looking in the spark plug hole. See Figure 14.
Both rocker arms should move freely and both valves are closed.
If not, repeat this step.
Slide the feeler gauge between the rocker arm and the valve return spring. Measure the clearance between the valve stem and rocker arm. Do both intake and exhaust valves. See Figure 15.
The recommended clearance for both intake and exhaust is .003-.006” (.076-.152mm). Use a standard (.127mm) feeler gauge. The feeler gauge should slide between the rocker arm and valve stem with a slight amount of resistance without binding.
