SAFETY RULES

OPERATION

• Never operate the tiller without guards, covers, and hoods in place.

• Never start the engine or operate the tiller with the wheels in the free-wheel position. Make sure the wheel lockpins are engaged through the wheel hubs and wheel axle. Disengage wheel lockpins to permit free-wheeling only when engine is stopped.

• Keep hands, feet, and clothing away from rotating parts. Keep clear of tiller tines at all times.

• Tines and wheels rotate when tiller is engaged in

forward or reverse-- in forward, tines and wheels

rotate when the drive safety control levers are pulled

down; in reverse, wheels and tines rotate when the

reverse handle is pulled back towards the operator.

Releasing the drive safety control levers to neutral

stops the wheels and tines.

• Be extremely cautious when operating in reverse.

Take extra care to avoid slipping or falling, and to keep feet clear of tines.

• Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic.

• After striking a foreign object, stop the engine, remove the wire from the spark plug, thoroughly inspect the tiller for any damage, and repair the damage before restarting and operating the tiller.

• If vegetation clogs the tines, raise the handlebars to

elevate the tines, and run the tiller in reverse. If this

does not clean clogged vegetation from the tines,

STOP THE ENGINE AND DISCONNECT THE SPARK PLUG WIRE before removing vegetation

by hand.

• Engine muffler will be hot from operation. Do not touch it with bare skin or a severe burn may result.

• If the unit should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

• Never allow bystanders near the unit.

• Use only attachments and accessories approved by the manufacturer of the tiller.

• Never operate the tiller without good visibility or light.

• Be careful when tilling in hard ground. The tines may catch in the ground and propel the tiller backward. If this occurs, let go of the handlebars and do not restrain the machine.

CAUTION

Please do not start your tiller until you have read the Manual that came with your engine, and the sections in this manual titled Controls, Adjustments and Safety. If you have read these, follow the steps below to start your tiller. Always perform this pre-start checklist before starting the engine.

OPERATION

ENGINE IS SHIPPED FROM FACTORY WITHOUT OIL. YOU MUST ADD ENGINE OIL BEFORE STARTING ENGINE.

START-UP

The controls required to start and run the rototiller are located on the engine and are marked "Choke" and "Throttle".

A more detailed description of engine operation and all related precautions and procedures can be found in the engine manufacturer's manual that accompanies each tiller.

Cold Starts

1. Move choke lever to full choke position.

2. Move throttle lever to "start".

3. Pull starting rope out slowly one time and allow to return normally.

4. Pull starting rope out rapidly, and allow rope to return normally.

5. When engine starts, gruadually move choke lever to "no choke" position and increase throttle speed.

WARNING

Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is hot or running. Always move outdoors to fill the tank.

WARNING

Wheels must always be locked in the TILLING position when engine is running. Do not operate the tiller with the wheel lockouts unlocked. Always set the wheels in tilling position before starting engine.

WARNING

Always put the depth regulator lever in the transport position before starting engine. Tines should clear the ground.

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 starting rope out rapidly until engine starts. Allow rope to return normally.

3. Adjust throttle speed to "high" 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" the engine 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 "fast".

DANGER

Always keep hands and feet clear of rotating machine parts.

OPERATION

ARDISAM

WARNING

Temperature of muffler and near by areas may exceed 150° F. Avoid these areas.

WARNING

Do not move choke control to CHOKE to stop engine. Backfire or engine damage may occur.

SHUTTING DOWN

DANGER

Engine and surrounding parts become extremely hot during normal use, and will cause serious burn injuries if touched before the engine has cooled.

Allow engine to cool completely before touching these hot surfaces.

WARNING

To stop the engine at any time, move throttle control to the off position. To stop wheels and tines at any time, release drive safety control levers to neutral position.

TILLING

1. Adjust the depth regulator lever to desired tilling

depth.

NOTE: Raise depth regulator lever up one hole at a time, testing tiller operation after each raise. Raising depth regulator lever too high can result in loss of control of tiller!

2. Move the throttle control to fast.

3. Place the tiller in forward by pushing down on the

drive safety control levers--this will engage the wheels and tines.

NOTE: You can slow the tiller's forward advance at any time by putting slight downward pressure on the handlebars, or you can stop the tiller by releasing the drive safety control levers to the neutral position.

WARNING

To stop wheels and tines at any time, release drive safety control levers to neutral position.

WARNING

Always release drive safety control levers to neutral position before adjusting the depth regulator lever.

Practice operating the controls and tiller with tines out of ground before beginning to till. It is important that you know how to use the tiller properly, how to keep control at all times, how to stop the tines and wheels from turning, and how to stop the engine if necessary. If you do not know how to do these things, read the Controls, Adjustments and Safety sections before proceeding.

ARDISAM

TIPS

TILLING TIPS

The key to successful tilling is to begin with a shallow cut on the first 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, set the detent pin in the highest hole of the drag stake (follow instructions under Tilling on previous page). This will allow for shallow tilling. With the drag stake in this position, make several light passes over the area to be tilled. Reset for deeper depths with successive passes.

✮ If tiller jumps or skids uncontrollably, lower the drag

stake by placing the detent pin in a higher hole. This will allow for shallower tilling. Hold firmly to the handlebars to control sudden lurches.

✮ If weeds, tall grasses, vines, or other materials clog

or jam the tines, reverse the tiller to unwind vegetation.

Immediately release the drive control levers if the tines jam or you strike a foreign object. With drive control levers in neutral, push throttle control to stop position to stop the engine. Disengage the spark plug wire. When tines have stopped, remove foreign objects and check for damage.

WARNING

Extreme caution must be taken in selecting tilling depth. If you attempt to till too deeply for soil conditions, that is, with the drag stake in too high a position, loss of control could result.

WARNING

If removing material from the tines by hand, stop engine and remove spark plug wire first.

CULTIVATING TIPS

If you plan to use your tiller for cultivating:

✮ Plant rows on 20" - 22" centers for ease of turning.

✮ Set the depth regulator lever with the detent pin in

one of the higher holes. This will allow the shallow cultivation necessary to turn over weeds, and break up and aerate the soil.

Recommended tire pressure is 20 PSI. If tires do not have equal pressure, tiller will pull to one side.

Lubrication

Proper lubrication of moving mechanical parts of your rototiller is a very important part of care and maintenance. You should oil the moving parts shown at 10 hour intervals using a 30 weight oil.

Clean Tine Axle Shaft

1. Turn off engine. Engine must be cool.

2. Remove spark plug wire and secure from spark plug.

3. Tip the tiller forward. Block the tiller in position so that it rests on the engine mount and the tines are exposed.

4. Remove all vegetation, string, wire, and other material that may have accumulated on the axle between the inside set of tines and the seal on the transmission housing.

5. Tip the tiller back to a level position.

6. Replace spark plug wire.

STORAGE

PREPARE FOR STORAGE

Follow the steps below to prepare your tiller for storage. Read your engine manual for detailed instructions on preparing the engine for storage.

1. Protect wheels and axles from rust:

- Remove lockpin and slide wheel off hub.

- Coat the axles lightly with axle grease.

- Slide wheel back on hub and insert lockpin.

2. Drain fuel system completely following engine manufacturer's instructions or add fuel stabilizer to prevent fuel from gumming up during extended storage period.

3. While engine is still warm, drain the oil from the engine. Refill with fresh oil of the recommended grade.

4. Clean external surfaces, engine and cooling fan.

5. Remove spark plug, pour one ounce of SAE 30 oil into spark plug hole.

6. Plug hole and pull starter cord slowly to distribute oil evenly in cylinder head area.

7. Reinstall spark plug.

8. Transport unit to a suitable storage location. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage precautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of ignition and ignite, causing risk of explosion and fire.

9. If there is any possibility of unauthorized use or tampering, remove the spark plug and store it in a safe place before storing the rototiller unit away. Be sure to plug the spark plug hole to prevent foreign material from entering.

WARNING

Do not store tiller in an unventilated area where fuel fumes may reach flame, sparks, pilot lights or an ignited object. Drain fuel outdoors away from any ignition sources. Use only approved fuel containers.
