CONTROLS DESCRIPTION OF CONTROLS Throttle Lever ENGINE SWITCH THROTTLE LEVER The throttle lever controls engine speed and tiller tine rotation. Pulling the throttle lever towards the grip increases the engine speed which causes the tines to turn. Releasing the throttle lever reduces engine speed and stops the tiller tines from turning. The tiller will have the greatest tilling force at maximum engine speed. At idle, the tilling tines should stop rotating.
CONTROLS Transport Wheels CARRYING HANDLE The transport wheels are used to move the tiller around. Before tilling, the transport wheels must be removed and the drag bar installed in their place. RECOIL STARTER Carrying Handle The carrying handle rubber grip is used to hold the tiller when starting the engine. TRANSPORT WHEELS The carrying handle can be used to load/unload the tiller, and to assist in certain engine maintenance procedures.
BEFORE OPERATION ARE YOU READY TO OPERATE THE TILLER? Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Knowledge Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the tiller and its operation before you begin to use it. Know what to do in case of emergencies. Physical and Mental Readiness You must be alert and in good physical condition to operate the tiller.
BEFORE OPERATION IS YOUR WORKING AREA READY? Objects thrown by the tiller can cause serious injury. Be especially careful when crossing gravel drives, walks or roads. Before operating the tiller, carefully inspect the area, and remove all objects that could be thrown by, or entangled in, the tilling attachment, such as rocks, broken glass, nails, wire, or string. Never operate the tiller without good visibility or light. Clear the area of children, bystanders, and pets.
OPERATION SAFETY PRECAUTIONS Before operating the tiller for the first time, please review the IMPORTANT SAFETY INFORMATION (see page 4) and the chapter titled BEFORE OPERATION (see page 10). Even if you have operated other tillers, take time to become familiar with the operation of this tiller’s controls and handling. For your safety, avoid starting or operating the engine in an enclosed area, such as a garage.
OPERATION Starting The Engine 1. Move the engine switch to the ON position. 2. To start a cold engine, move the choke lever to the CLOSED (E) position. To restart a warm engine, leave the choke lever in the OPEN position. 3. To start a cold engine, or after refueling an engine that has run out of fuel, press the priming bulb repeatedly until fuel can be seen in the clear plastic fuel-return tube. To restart a warm engine, it is not necessary to press the priming bulb. 4.
OPERATION TILLER OPERATION 1. Install the drag bar (see page 12). Honda recommends using the drag bar when tilling. The tiller can be difficult to control without the drag bar installed. 2. Adjust the handlebar to a comfortable position (see page 12) (waist height for normal tilling operation). 3. Set the tilling depth by moving the drag bar up or down (see page 12). 4. 5. 6. 7. The ideal height of the drag bar will depend on the type of soil being tilled, and soil conditions at the time of tilling.
OPERATION LOCK PIN Tilling In Rocky Soil [a] If you are tilling in stony or rocky soil, and experience continual rock jams between tines, set the tiller tines in the rocky soil pattern to help alleviate the problem. 1. Stop the engine (see page 13). 2. Disconnect the spark plug wire (see page 22). 3. Tip the tiller forward on the carrying handle as shown. 4. Remove the lock pins from the left and right tine shafts by turning them UP [a] and pulling them OUT [b]. 5. Clean the tine shafts. 6.
OPERATION OHV Angled portion edge should enter the soil View from the rear. LOCK PIN B C Narrow Cultivating The two outer tines can be removed to give you a narrower cultivating width. This width is approximately 6 inches. This will give you the ability to get between very closely spaced plants. In order to do this, pull the lock pin out of the hole in the end of the tine shaft. Slide the outside tine set off the tine shaft and place a tine spacer, included with your tiller, over the tine shaft.
MAINTENANCE & ADJUSTMENTS SERVICING YOUR HONDA TILLER THE IMPORTANCE OF MAINTENANCE MAINTENANCE SAFETY Good maintenance is essential for safe, economical, and trouble-free operation.

TRANSPORTING/STORAGE TRANSPORTING Before Loading HANDLE BAR KNOBS THROTTLE CABLE & ENGINE STOP Always turn the engine switch to the OFF position. Make sure the fuel cap is securely tightened. Install the wheels to provide added stability when transporting (see page 12). UPPER HANDLEBARS If the engine has been running, allow it to cool for at least 15 minutes before loading the tiller on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials.
TRANSPORTING/STORAGE Fuel Draining the Fuel Tank and Carburetor Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that restrict the fuel system. If the gasoline in your tiller deteriorates during storage, you may need to have the carburetor and other fuel system components, serviced or replaced. Drain the fuel from the fuel tank to a suitable container (see page 26).
TRANSPORTING/STORAGE STORAGE PRECAUTIONS REMOVAL FROM STORAGE If your tiller will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.
