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 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 over spectacles or standard safety glasses. HARD TO SHIFT GEARS HOW TO USE YOUR TILLER Know how to operate all controls before adding fuel and oil or attempting to start engine. • STOPPING (See Fig. 9) DEPTH STAKE (See Fig.
OPERATION TURNING • • • • • • • • Release the drive control bar. Move throttle control to “SLOW” position. Place shift lever indicator in “F” (forward) position. Tines will not turn. Lift handle to raise tines out of ground. Swing the handle in the opposite direction you wish to turn, being careful to keep feet and legs away from tines. When you have completed your turn-around, release the drive control bar and lower handle. Place shift lever in till position and move throttle control to desired speed.
OPERATION TO START ENGINE (See Fig. 13) TILLING HINTS CAUTION: Keep drive control bar in “DISENGAGED” position when starting engine. CAUTION: Until you are accustomed to handling your tiller, start actual field use with throttle in slow position (mid-way between “FAST” and “IDLE”). 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. • Make sure spark plug wire is properly connected.
OPERATION TINE SHEAR PINS ADJUST WHEELS FOR CULTIVATING (See Figs. 16 and 17) The tine assemblies on your tiller are secured to the tine shaft with shear pins (See “TINE REPLACEMENT” in the Service and Adjustments section of this manual). If the tiller is unusually overloaded or jammed, the shear pins are designed to break before internal damage occurs to the transmission. • If shear pin(s) break, replace only with those shown in the Repair Parts section of this manual.

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. 21) 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. TILLER TIRE CARE TO ADJUST HANDLE HEIGHT (See Fig. 22) CAUTION: When mounting tires, unless beads are seated, overinflation can cause an explosion. Select handle height best suited for your tilling conditions. Handle height will be different when tiller digs into soil. • First loosen handle lock lever.
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.
SERVICE AND ADJUSTMENTS TO REMOVE BELT GUARD (See Fig. 27) TO REPLACE GROUND DRIVE BELT (See Figs. 27 and 28) NOTE: For ease of removal, remove hairpin clip and clevis pin from left wheel. Pull wheel out from tiller about 1 inch (2.5 cm). • Remove two (2) screws from side of belt guard. • Remove hex nut and washer from bottom of belt guard (located behind wheel). • Pull belt guard out and away from unit. • Replace belt guard by reversing above procedure.
SERVICE AND ADJUSTMENTS ENGINE TO ADJUST THROTTLE CONTROL CABLE (See Fig. 29) The throttle control has been preset at the factory and adjustment should not be necessary. If adjustment is necessary, proceed as follows: • With engine not running, move remote throttle control lever to “FAST” position. • If throttle lever on engine touches high speed stop, no further adjustment is necessary. If throttle lever does not touch high speed stop, continue with adjustment procedure. • Loosen cable clamp screw.
STORAGE ENGINE OIL 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. 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.
