ASSEMBLY Your new tiller has been assembled at the factory with exception of those parts left unassembled for shipping purposes. To ensure safe and proper operation of your tiller all parts and hardware you assemble must be tightened securely. Use the correct tools as necessary to insure proper tightness. TOOLS REQUIRED FOR ASSEMBLY FRONT overhead_views_7 A socket wrench set will make assembly easier. Standard wrench sizes are listed.
ASSEMBLY UNPACK CARTON & INSTALL HANDLE (See Fig. 2) INSTALL DEPTH STAKE ASSEMBLY (See Fig. 3) • • CAUTION: Be careful of exposed staples when handling or disposing of cartoning material. • IMPORTANT: WHEN UNPACKING AND AS SEMBLING TILLER, BE CAREFUL NOT TO STRETCH OR KINK CABLE(S). • • •. Cut cable ties securing handle column. Route cable(s) as shown and slide handle column onto handle mount. • Remove all packing from carton.
OPERATION KNOW YOUR TILLER READ THIS MANUAL AND SAFETY RULES BEFORE OPERATING YOUR TILLER. Compare the illustrations with your tiller to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. These symbols may appear on your Tiller or in literature supplied with the product. Learn and understand their meaning.
OPERATION The operation of any tiller can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields before starting your tiller and while tilling. We recommend a wide vision safety mask for over spectacles or standard safety glasses. TILLING HOW TO USE YOUR TILLER The speed and depth of tilling is regulated by the position of the depth stake and wheel height. The depth stake should always be below the wheels for digging.
OPERATION TO TRANSPORT CAUTION: Fill to within 1/2 inch of top of fuel tank to prevent spills and to allow for fuel expansion. If gasoline is accidentally spilled, move machine away from area of spill. Avoid creating any source of ignition until gasoline vapors have disappeared. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. CAUTION: Before lifting or transporting, allow tiller engine and muffler to cool. Disconnect spark plug wire. Drain gasoline from fuel tank.
OPERATION Fuel Valve • Spark Plug Throttle Control Choke Control • Recoil Starter Engine Switch • Fuel Valve Spark Plug Throttle Control Soil conditions are important for proper tilling. Tines will not readily penetrate dry, hard soil which may contribute to excessive bounce and difficult handling of your tiller. Hard soil should be moistened before tilling; however, extremely wet soil will “ball-up” or clump during tilling. Wait until the soil is less wet in order to achieve the best results.

MAINTENANCE Disconnect spark plug wire before performing any maintenance (except carburetor adjustment) to prevent accidental starting of engine. Prevent fires! Keep the engine free of grass, leaves, spilled oil, or fuel. Remove fuel from tank before tipping unit for maintenance. Clean muffler area of all grass, dirt, and debris. Do not touch hot muffler or cylinder fins as contact may cause burns. ENGINE LUBRICATION Use only high quality detergent oil rated with API service classification SG-SL.
MAINTENANCE COOLING SYSTEM (See Fig. 14) MUFFLER Your engine is air cooled. For proper engine performance and long life keep your engine clean. • Clean air screen frequently using a stiff-bristled brush. • Remove blower housing and clean as necessary. • Keep cylinder fins free of dirt and chaff. Do not operate tiller without muffler. Do not tamper with exhaust system. Damaged mufflers or spark arresters could create a fire hazard. Inspect periodically and replace if necessary.
SERVICE AND ADJUSTMENTS CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come into contact with plug. MID-WIDTH TILLING - 24" PATH (See Fig. 17) • Assemble holes “A” in tine hubs to holes “C” in tine shaft. TILLER TO ADJUST HANDLE HEIGHT (See Fig. 15) Factory assembly has provided lowest handle height. Select handle height best suited for your tilling conditions. Handle height will be different when tiller digs into soil.
SERVICE AND ADJUSTMENTS FINAL CHECK “ON” POSITION • With tine control “ON” (held down to handle) push down on handle to raise tines off the ground. • Slowly pull recoil starter handle while observing tines. Tines should rotate forward. • If tines do not rotate, inner wire of control cable is too loose. Loosen cable clip and pull cable up to remove slack and retighten clip. • Recheck in “ON” position and adjust if necessary.
STORAGE Immediately prepare your tiller for storage at the end of the season or if the unit will not be used for 30 days or more. ENGINE OIL Drain oil (with engine warm) and replace with clean oil. (See “ENGINE” in the Maintenance section of this manual). WARNING: Never store the tiller with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
