2.3 ENGINE SAFETY PRECAUTIONS
⚠ Warning Carbon Monoxide Poisoning
Engines give off carbon monoxide, an odorless, colorless, poisonous gas. Carbon monoxide may
be present even if you do not smell or see any engine exhaust. Breathing carbon monoxide can
cause nausea, fainting or death, in addition to drowsiness, dizziness and confusion. If you
experience any of these symptoms, seek fresh air and medical attention immediately.
WARNING
NGINES GIVE OFF CARBON MONOXIDE, AN ODORLESS, COLORLESS, POISONOUS GAS. CARBON MONOXIDE
MAY BE PRESENT EVEN IF YOU DO NOT SMELL OR SEE ANY ENGINE EXHAUST. BREATHING CARBON
MONOXIDE CAN CAUSE NAUSEA
CONFUSION.
IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, SEEK FRESH AIR AND MEDICAL ATTENTION IMMEDIATELY.
, FAINTING OR DEATH, IN ADDITION TO DROWSINESS, DIZZINESS AND

• Never point the exhaust towards anyone. People should always be a minimum of ten feet
away from the operation of the engine and its attachments.
• Do not change the engine governor settings or over-speed the engine.
GASOLINE FIRES AND HANDLING FUEL SAFELY
⚠ Warning gasoline is highly flammable and explosive
You can be burned or seriously injured when handling fuel. Use extreme care when handling
gasoline or other fuels. They are flammable, and vapors are explosive.
• When storing extra fuel be sure that it is in an appropriate
container and away from any fire hazards.
• 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).
• Always fill fuel tank outside in a well-ventilated area. Never fill
fuel tank with fuel indoors. (Examples include: basement, garage,
barn, shed, house, porch, etc.) Never fill tank near appliances
with pilot lights, heaters, or other ignition sources. If the fuel has
to be drained, this should be done outdoors. The drained fuel should be stored in a
container specifically designed for fuel storage or it should be disposed of carefully.
• Never remove the fuel cap or add fuel with the engine running. Stop engine and allow to
cool before filling.

12. Do not overload the machine capacity by attempting to till too deep or too fast.
13. Never operate the machine at high speeds on slippery surfaces. Look behind and use care
when backing up.
14. Never allow bystanders near the unit.
15. Use only attachments and accessories approved by the manufacturer of the tiller.
16. Never operate the tiller without good visibility or light.
17. Be careful when tilling in hard ground. The tines may catch in the ground and propel the
tiller forward. If this occurs, let go of the handlebars and do not restrain the machine.
2.8 Maintenance and Storage
1. Keep machine, attachments, and accessories in safe working conditions.
2. Check assembly pins, engine mounting bolts, and other bolts at frequent intervals for
proper tightness to be sure the equipment is in safe working condition.
3. Never store the machine with fuel in the fuel tank inside a building where ignition sources
are present, such as hot water and space heaters, clothes dryers, etc. allow the engine to
cool before storing in any enclosure.
4. Always refer to the storage instructions (Section 10) for important details if the tiller is to
be stored for an extended period.

Prior to assembling your tiller, make sure that you have a clear work space and that there are no
missing parts.
1. Remove the tiller from the box. Do not attempt to lift the tiller from the box. After
opening the top, remove manuals, protective packaging and all unassembled parts
including the parts bag. Note location of cross brace, carefully remove from cardboard.
Place these parts off to the side for later assembly. Carefully cut all four sides of the box
and lay the sides flat on the floor as shown below. While moving through the first few
steps of assembly, temporarily leave the tiller resting on the top of the box containing the
tines.

5. Once all handle mounting bolts are in place, only partially tighten them, do not fully
tighten until all the remaining mounting hardware for the tie and cross brace, is started
with a snug fit.
6. Install the two handle bar tie braces (A) shown below, to the transmission using two ¼” x
1” for the top two holes. The first/top one is also used to bolt the belt guard upper
bracket (B).
7. Using one 5/16” x 1 ¼” mount the tie braces and a P-clip/cable guide for throttle cable, in
the bottom hole on the right side as shown below:
A- Handle bar tie brace (2)

9. Tighten all bolts a little at a time going from one to the next, moving around in a crisscross
pattern until they are all tight.
10. Install clutch cable through cable guides and ensure both clutch cable guides are adjusted
accordingly, for smooth clutch cable action. Hook loop end of the cable at bottom into
notch of clutch arm, see left image below. At the top end of the clutch cable, see right
image below, and hook one end of spring into chain and the other into hole in clutch
lever. The clutch cable should be adjusted so that the spring will be extended ¼” – ½”
when lever is engaged however making certain the belt will slip and tines stop turning,
when the lever is released.
11. The throttle cable is mounted to the engine by the factory. Carefully mount the control
end to the cross brace, by rotating the throttle handle enough to fit through the throttle
mount, coming from the underside of the cross brace. Use two #6 x ½” bolts and lock nuts
to mount. Test for smooth movement of throttle handle between slow and fast. Note:
“Off” position of throttle handle will only slow engine speed and aid in disengaging the
tines when clutch lever is released, it will not stop the engine. Use engine on/off switch
located on engine to turn engine off or on.

4.1 Final Set-up
1. Check the transmission to ensure that it has the proper amount of lube
a. Remove check plug.
b. Use 90 wt. gear lube. Approx. 1 pt.
c. Fill until check plug hole overflows.
d. Replace plug. NOTE: do not overtighten.
2. Remove the engine dipstick and fill crankcase with oil, according
to engine owner’s manual.
NOTE: Engine is shipped from factory without oil. You must add
engine oil before starting engine. If engine is started without oil,
engine may be damaged beyond repair and will not be covered by
warranty.
3. Fill the fuel tank with clean, fresh, lead-free gasoline. Do not fill
fuel tank completely, allow space for fuel to expand. DO NOT MIX
OIL WITH GASOLINE.
5 OPERATING CONTROLS
5.1 Speed
1. The tiller will dig deeper and move forward slower by pushing down on the handles.
2. The tiller will move ahead faster, but at a shallower depth, by raising the handles.
3. The speed of the tines is controlled by the use of the throttle control lever.
5.2 Depth of Tilling
1. The proper throttle speed and correct up and down hand pressure on the handles must
be used to accomplish a quality till while accommodating operator ability/safety.
2. Raising up means going forward, this action releases the grip of the drag stake in the soil,
allowing the tiller to progress ahead.
3. Pushing down means slowing down or even standing still. This directs the drag stake into
the soil, thus holding the tiller back.
4. Adjust throttle for desired speed and depth of tines.
5.3 Throttle Control Lever
The throttle control lever, located on the handle cross brace, controls engine speed. When
starting, place control lever in center position. Then adjust to desired speed. To stop engine,
move throttle control lever to low idle position. Push ignition on/off switch to off located on
engine.

⚠ WARNING: Engine is shipped from factory without oil. You must add engine oil before
starting engine. If engine is started without oil engine may be damaged beyond repair and will
not be covered by warranty.
3. Read engine manual for full instructions and safety warnings.
4. Place tiller on level ground.
5. Remove dipstick. Wipe with clean cloth.
6. Reinsert dipstick (do not screw dipstick back in). Remove dipstick and check.
7. Oil should be at FULL level.
8. If oil is required, add slowly. Recheck level.
9. Change oil if contaminated.
10. Tighten dipstick and clean around oil fill area before starting.
11. Fill engine with clean unleaded gasoline according to the engine owner’s manual.
⚠ WARNING: Gasoline is flammable. Use caution when handling or storing gasoline. Never fill
the gas tank while the engine is running or hot. Do not fill fuel tank completely, allow space for
fuel to expand. Allow the engine to cool before adding gas. Clean any spilled gasoline.
12. Ensure that the air element/filter and seal are installed properly. Clean and maintain
according to engine owner’s manual.
13. Familiarize yourself with all operating controls.
⚠ DANGER: Never operate the tiller without proper guards, plates, or other safety devices in

6.2 Starting the Engine
Before starting the engine, check the machine against the Set-Up instructions (section 4) to see
that it is properly assembled. Review the safety suggestions and operating instructions for safe
and proper use of the tiller.
6.3 Pre-Start
1. Check the spark plug wire for proper connection on the spark plug.
2. Check the oil for proper level.
3. Make certain clutch lever is in disengaged position.
6.4 Filling Fuel Tank
We recommend the use of clean, fresh, lead-free gasoline. The use of lead-free gasoline results in
few combustion deposits and longer valve life. Do not fill fuel tank completely,
allow space for fuel to expand. Provide approximately ¼” of tank space for fuel
expansion.
1. Shut-off engine and allow engine to completely cool before refilling
the fuel tank.
2. Move to a well-ventilated area, outdoors, away from flames and
sparks.
3. Clean debris from area around the fuel cap.
4. Loosen fuel cap slowly. Prevent the cap from coming in contact with
dirt or debris.
5. Carefully add fuel without spilling.
6. Do not fill gas tank completely full, allow space for fuel to expand.
7. Immediately replace fuel cap and tighten. Wipe off spilled fuel to allow it to dry before
starting engine.
CAUTION
ENGINE IS SHIPPED FROM FACTORY WITHOUT OIL. YOU MUST ADD ENGINE OIL BEFORE STARTING ENGINE. IF ENGINE IS
STARTED WITHOUT OIL, ENGINE MAY BE DAMAGED BEYOND REPAIR AND WILL NOT BE COVERED BY WARRANTY.
NEVER STORE ENGINE WITH FUEL IN THE TANK INDOORS. FUEL AND FUEL VAPORS ARE HIGHLY FLAMMABLE.
AN ADULT ONLY MUST ALWAYS HANDLE AND FILL THE ENGINE WITH FUEL.
ALWAYS HANDLE GAS IN A WELL-VENTILATED AREA, OUTDOORS, AWAY FROM FLAMES OR SPARKS.
DO NOT START ENGINE IF FUEL IS SPILLED. WIPE OFF EXCESS FUEL AND ALLOW TO DRY. REMOVE ENGINE FROM AREA AND

ENGINE MUST BE ON LEVEL SURFACE WHEN CHECKING OIL LEVEL OR FILLING WITH OIL.
6.5 Checking and adding Oil
1. Be sure the engine is located on a level surface before checking or refilling oil. Clean
around oil fill area.
2. Be sure engine is cool.
3. Unscrew dipstick and wipe clean with cloth.
4. Reinsert dipstick (do NOT thread in for accurate reading).
5. Remove and check dipstick. If no oil shows on the dipstick, refill so that the oil level
appears between the low and high marks on the dipstick.
6. Change oil if contaminated.
*NOTE: See engine Owner’s Manual for proper oil maintenance instructions
IMPORTANT
FAILURE TO DO SO CAN RESULT IN OVERFILLING THE ENGINE WITH OIL WHICH WILL
IMPAIR THE ENGINE’S PERFORMANCE.
6.6 Cold Starting Procedure
1. Move throttle control lever to center position.
2. Move choke control to choke position. Hold the handle with your left hand while pulling
the starter rope with your right. Pull the rope out slowly until the engine reaches the start
of the compression cycle (the rope will pull slightly harder at this point). Then allow the
rope to retract fully.
3. Pull the rope with a continuous full arm stroke. Keep a firm grip on the starter handle and
let the rope rewind slowly. Do not let the handle snap back against the recoil starter.
4. Repeat steps number 2-3 above until engine starts. If engine fails to start after 3 pulls on
the rope, repeat step number 1-2 above as necessary. Slowly move choke control to RUN
position after engine has responded and engine warms up.
5. As the engine warms up, move the throttle lever to full throttle position. Allow engine
warm-up period before operating tiller.
⚠ NOTE: A warm engine may start without choking. Do not use the choke if engine is hot.
6.7 Stopping Engine
1. Move the throttle control to slow/idle position.
2. Turn ON/OFF switch to off position located on engine.

6.8 Operation
⚠ IMPORTANT: Keep hands clear of belt and tines while engine is running.
⚠ WARNING: For safe operation, the chain drive must disengage immediately when clutch lever
is released. If it does not, adjust belt and cable tension as described in Section 7 in this manual.
Never leave the tiller unattended with the engine running.
DANGER
lever is released. If it does not, stop the tiller, adjust belt and cable tension as described
in Adjustments section of this manual. Never leave the tiller unattended with the engine
running. Children are attracted to a running tiller and could be injured if struck by the
rotating tines.
WARNING
clean tines while engine is running, at risk of sever injury.
1. When ground is hard (especially during spring and fall tilling season), place wheels in up
position by pulling the locking pin from the wheel yoke and repositioning the wheel frame
bar, re-insert the pin to reposition and lock wheels in the up position. For weeding or
cultivation, wheels may be left down if you prefer.
2. Adjust the drag stake for comfortable operation. This is done by pulling the locking pin
from the drop stake locking hub and sliding the drag stake down or up. The drag stake
should be set so that when it is firmly in the ground, and your hands are on the tiller
handle, your arms hand comfortably with the elbows slightly bent. Once determined reinsert locking pin.
3. Move the throttle control to center position. Start the engine and allow it to warm up,
then set the throttle at about half speed. After you have become familiar with the tiller,
you may want to run the engine a little faster.
4. Press down firmly on the handles and squeeze the clutch lever. The tines will begin to
turn, but the tiller should not move forward. If it does, don’t pull backwards – merely
press down harder on the handles. When you find the right amount of downward
pressure so that the tines are beginning to dig however not moving forward, release the
pressure slightly. As you release it you’ll notice the tiller beginning to move forward.

⚠ NOTE: The whole tilling operation is controlled by the amount of pressure you put on the drag
stake. Do not fight the tiller. Stand between the handles and press down to go slower and dig
deeper and release the downward pressure to move forward faster. In normal soil, the actual up
and down movement of the handles will be no more than an inch or two.
6.9 Operation Tips
To acquire the knack of letting the tiller do the work without effort on the part of the operator,
we offer the following suggestions:
1. Adjust drag stake so the handles are at such a height that your arms hang straight down
to contact them. Rear wheels should be in up position for deep tillage or ease of turning
in confined areas.
2. Operate the tiller at about ¾ throttle.
3. Don’t hurry the job – proceed at a slow walk – give the machine time to do its job.
4. Concentrate on keeping your arms relaxed (There is a natural tendency for any beginner
to tense up). Operating the tiller actually takes very little effort. Let the tiller do the work.
5. When tilling on sloping ground, turn the front of the machine uphill to sufficiently
counteract the tendency to run downhill.
6. For best results, operate at reduced throttle settings when ground is extremely hard or
rough.
7. Tighten all nuts and bolts periodically.
6.10 Tilling Pattern
1. Whenever possible till the soil in the direction in which the planting or rows will run. If the
soil is extremely hard and dry, it may be advisable to till across the plot on the first digging
and then obtain the depth you want by tilling in the direction the planting will be done.

7.1 Clutch Adjustment
Proper clutch adjust is very important. Minor adjustment, if needed, can be made by using the
links on the clutch cable chain only. However, the friction type clutch may need further
adjustments as the “V” belt wears. Adjust as follows:
1. Remove belt guard.
2. Loosen 4 engine mount bolts. Slide engine forward or backwards as required.
3. Unhook clutch cable from load spring.
4. Push upward on idler pulley to take all slack from the drive belt. Distance between the
inside of belt at the idler pulley should be between 2 7/8 and 3 1/8 of an inch.
5. Ensure pulleys are aligned with a long straight edge.
6. Retighten engine mounting bolts (17
foot lbs. of torque).
7. Remove all the slack from clutch cable
and hook spring in proper chain link.
8. Check your adjustment by starting the
tiller and holding the tines off the
ground. If the tines turn without any
hand pressure on the engage lever,
the adjustment is too tight. Unhook
the clutch load and hook into next
chain link to lengthen clutch cable. If
the cable spring on the clutch handle
doesn’t stretch when you hold the clutch handle all the way in, the adjustment is too
loose. Unhook spring end from chain and hook next link to shorten clutch cable.
7.2 Wheel Height Adjustment
1. Wheel position may be adjusted. To place wheels in up position, pull the locking pin from
the wheel yoke and repositioning the wheel frame bar re-insert pin to reposition and lock
wheels in the up position. For weeding or cultivation, wheels may be left down if you
prefer.
7.3 Tine Adjustment
The standard tilling width is 26” with both inner and outer tine assemblies mounted. Tilling width
is 14” with outer assemblies removed.
1. To remove outer tine assemblies from inner tine assemblies, remove pin clip from clevis
pin.
2. Slide clevis pin out and remove outer tine assembly.

8 Maintenance
⚠ DANGER: To avoid possible serious bodily injury, when performing any adjustments, remove
the spark plug wire and place the wire away from the plug to prevent accidental starting.
8.1 Periodic Check
1. Regularly check all bolts and nuts for tightness.
2. If the belt begins to bottom out on the engine pulley, then replacement of the pulley is
needed. This is noticeable by the pulley “V” bottom becoming shiny.
8.2 Engine Oil
1. Check the oil level before starting the engine and after every five hours of operation.
2. Be sure engine is cool.
3. Before removing the filer plug, clean the area around it to prevent dirt from entering the
oil fill hole.
4. The engine should be in a level position when checking the oil.
5. Remove the filler plug and fill the crankcase with oil.
6. Use a high-quality detergent oil – refer to your engine owner’s manual for oil
requirements.
7. Add oil as necessary to keep oil level as indicated. Detergent oils keep the engine cleaner
and reduce the formation of gum and varnish deposits. Nothing should be added to the
recommended oil.
8. Change the oil after the first 20 hours of operation and every 100 hours there-after or
every 6 months, whichever comes first. Always change oil while the engine is warm. Oil
may be drained through the oil drain port towards the bottom of the engine. Refer to
your Engine Owner’s Manual for complete details.
8.3 Dual Filter Element Air Cleaner
Clean cartridge at three month intervals or every 50 hours, whichever occurs first.
⚠ NOTE: Service more often under dust conditions.
1. Remove the wing nut from the air cleaner cover and remove cover.
2. Remove the wing nut from the air filter and remove the filer.
3. Remove the foam filter, if equipped, from the paper filter.

4. Inspect both air filter elements and replace them if they are damaged.
5. Always replace the paper air filter element at 300 hours.
6. Re-install filters making certain all seals and gaskets are in properly installed
⚠ NOTE: Replace or clean cartridge included with DUAL ELEMENT AIR CLEANER yearly or every
300 hours as described in CARTRIDGE AIR CLEANER. Service more often if necessary.
8.4 Cleaning the Cooling System
1. Remove blower housing and clean regularly.
⚠ NOTE: Grass or chaff may clog cooling system after prolonged service. Continued operation
with a clogged cooling system causes severe overheating and possible engine damage.
8.5 Belt Replacement
The drive belt located on the left side of the machine. To replace a worn or slipping belt proceed
as follows:
⚠ DANGER: To avoid possible serious bodily injury, when performing any adjustments, remove
the spark plug wire and place the wire away from the plug to prevent accidental starting.
1. Remove belt guard.
2. Make sure clutch lever is in disengaged position.
3. Start at the top of 10” pulley and begin removing belt in clockwise direction (facing tiller
from left side). If tension on belt is too great the idler pulley may be pulled downward to
relieve pressure on belt.
4. Once belt is off 10” pulley, remove it from smaller pulley.
5. Replace belt by reversing sequence of steps above.
6. Replace belt guard.
8.6 Cleaning
⚠ IMPORTANT: If the engine has been running, allow it to cool for at least half an hour before
washing.
1. Wash the tiller, including the underside, after use.
2. Wash the engine by hand, be careful to prevent water or debris from entering the air
cleaner.
⚠ NOTE: Do not use a garden hose or pressure washing equipment, it can force water into the
air cleaner. Water in the air cleaner will soak the filter element and can enter the carburetor or
engine cylinder, causing damage.
3. After washing the tiller, wipe dry.

4. After the tiller is clean and dry, touch up any damaged paint and coat other areas with a
light film of oil.
5. Wipe the tines with oil or spay to prevent rusting.
9 LUBRICATION
9.1 Wheels
Lubricate wheels and wheel support shafts once a month or every 40 operation hours with #30
oil. Apply oil to axle and hub at back of wheel. Spin to allow oil to move into bearings.
In extremely dusty conditions, wheels may become tight because of dust in bearing area. When
this condition occurs, remove the wheels. Clean axle and wheel bearing surfaces with solvent or
emery cloth, then oil and reassemble.
9.2 Clutch Lever Pivots
Apply a Few drops of SAE 30 oil to the clutch hand lever and idler lever pivots as required to
maintain a free and smooth operation of clutch.
9.3 Transmission
