OPERATION KNOW YOUR TILLER READ THIS OWNER'S 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 00155 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. HOW TO USE YOUR TILLER TINE OPERATION - WITH WHEEL DRIVE • Know how to operate all controls before adding fuel and oil or attempting to start engine. • STOPPING (See Fig.
OPERATION • Move throttle control to “FAST” position for deep tilling. To cultivate, throttle control can be set at any desired speed, depending on how fast or slow you wish to cultivate. • • AROUND TOWN • Disconnect spark plug wire. • Drain fuel tank. • Transport in upright position to prevent oil leakage. IMPORTANT: ALWAYS RELEASE DRIVE CONTROL BAR BEFORE MOVING SHIFT LEVER INTO ANOTHER POSITION. TURNING • • • • • • Hold the drive control bar against the handle to start tiller movement.
OPERATION ADD GASOLINE • TO START ENGINE (See Fig. 13) Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. CAUTION: KEEP TINE CONTROL IN “OFF” POSITION WHEN STARTING ENGINE.
OPERATION TILLING HINTS CULTIVATING Cultivating is destroying the weeds between rows to prevent them from robbing nourishment and moisture from the plants. At the same time, breaking up the upper layer of soil crust will help retain moisture in the soil. Best digging depth is 1" to 3" (2.5-7.5 cm). Lower the outer side shields to protect small plants from being buried.

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.
MAINTENANCE COOLING SYSTEM (See Fig. 19) SPARK PLUG 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. Replace spark plugs at the beginning of each tilling season or after every 25 hours of use, whichever comes first.
SERVICE AND ADJUSTMENTS CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come into contact with plug. TILLER TO REMOVE WHEEL (See Fig. 21) TO ADJUST HANDLE HEIGHT (See Fig. 20) • Select handle height best suited for your tilling conditions. Handle height will be different when tiller digs into soil. • First loosen handle lock lever. • Handle can be positioned at different settings between “HIGH” and “LOW” positions.
SERVICE AND ADJUSTMENTS GROUND DRIVE BELT ADJUSTMENT ( S e e Fig. 23) TO REPLACE GROUND DRIVE BELT (See Figs. 22 and 23) • • • • • • Remove belt guard as described in “TO REMOVE BELT GUARD”. Remove old belt by slipping off engine pulley first then remove from transmission pulley. Place new belt in groove of transmission pulley and into engine pulley. BELT MUST BE IN GROOVE ON TOP OF IDLER PULLEY. NOTE POSITION OF BELT TO GUIDES. Check belt adjustment as described below. Replace belt guard.
SERVICE AND ADJUSTMENTS TINE REPLACEMENT (See Figs. 24, 25 and 26) • CAUTION: Tines are sharp. Wear gloves or other protection when handling tines. • A badly worn tine causes your tiller to work harder and dig more shallow. Most important, worn tines cannot chop and shred organic matter as effectively nor bury it as deeply as good tines. A tine this worn needs to be replaced.
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). CAUTION: 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.
TROUBLESHOOTING POINTS Will not start 1 Out of fuel. 1 Fill fuel tank. 2 Fuel valve “OFF” 2 Turn fuel valve to the “ON” position. 3 Engine Switch “OFF” 3 Turn engine switch to the “ON” position. 4 Engine not “CHOKED” properly. 4 See “TO START ENGINE” in Operation section. 5 Engine flooded. 5 Wait several minutes before attempting to start. 6 Bad spark plug or improper gap. 6 Replace spark plug or adjust gap. 7 Dirty air filter. 7 Clean/replace air filter. 8 Water in fuel.
