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 HOW TO USE YOUR TILLER TINE OPERATION - WITH WHEEL DRIVE Always release drive control bar before moving shift lever into another position. • Tine movement is achieved by moving shift lever to either the counter rotating ( ) till position or the forward rotating ( ) till position and engaging drive control bar. Know how to operate all controls before adding fuel and oil or attempting to start engine. STOPPING (See Fig. 9) TINES 1. Release drive control to stop movement. 2.
OPERATION • TILLING (See Fig. 12) • • • • Release depth stake pin. Pull the depth stake up for increased tilling depth. Place depth stake pin in hole of depth stake to lock in position. Place shift lever indicator in counter rotating ( ) till position. Hold the drive control bar against the handle to start tilling movement. Tines and wheels will both turn. Move throttle control to “FAST” position for deep tilling.
OPERATION TO START ENGINE (See Fig. 14) Oil Filler Plug Oil Level _a ine eng CAUTION: KEEP TINE CONTROL IN “OFF” POSITION WHEN STARTING ENGINE. When starting engine for the first time or if engine has run out of fuel, it will take extra pulls of the recoil starter to move fuel from the tank to the engine. 1. Make sure spark plug wire is properly connected. 2. Place the fuel valve to the "ON" position. 3. To start a cold engine, move the choke lever to the "ON" position. 4.
OPERATION CULTIVATING TILLING HINTS 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. 20) 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. 22) TO ADJUST HANDLE HEIGHT (See Fig. 21) • 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 (See Fig. 24) TO REPLACE GROUND DRIVE BELT (See Figs. 23 and 24) • • • • • • 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. 25, 26, and 27) 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.
