Lubricate the pawl and ratchet at least twice a season with a silicone type lubricant. Figure 21 shows the left hub cap. To take off the hub caps, remove the two hex nuts and lock washers on the inside of the wheel. Remove the hub cap. A cotter pin holds the ratchet in place. The pawls must pivot freely. Clean with a solvent, replace any broken or worn parts, and lubricate. The pawls and ratchet on the hub cap are assembled facing the opposite way. After reassembling, test the operation of the drive without the engine running. Engage the drive clutch (on the right handle) and pull the tiller backwards. Both wheels should lock. Push the tiller forward and both wheels should rotate. The wheels will “click” when the tiller is pushed forward. FIGURE 21. Tine and Wheel Drive Controls—Lubricate the pivot points on the clutch levers and the cables at least once a season with light oil. The controls must operate freely in both directions. Pivot Points—Lubricate all pivot points and linkages at least once a season with light oil. MAINTENANCE Ac wVrN*NG Disconnect the spark plug wire and ground it against the engine before performing any repairs or maintenance. IMPORTANT If for any reason the tines are removed from the tiller, be certain the tines are reassembled so that the sharp edge of the tines enter the soil first. Refer to item number one under “Operation.” ENGINE OIL After the first two hours of operating a new engine, drain the oil from the crankcase while the engine is still hot and refill the crankcase with new oil; thereafter change the oil after every 25 hours of operation. To avoid spilling gasoline on your lawn or driveway, plan to change the oil when the gasoline tank and carburetor are empty. To change the oil, refer to the separate engine manual. Check oil level every eight hours of operation. Be sure level is maintained full to point of overflowing. 11 I AIR CLEANER Under normal operating conditions, the air cljaner, located on top of the carburetor, must be service i after every ten hours of use. Under extremely dusty operating conditions, the air cleaner must be serviced after every hour of operation. To service the air Cleaner, refer to the separate ( ngine manual packed with your tiller. IMPORTANT Never run your engine without air cleaner completely assembled. Belt Cover FIGURE 22. CLEANING ENGINE AND TINE AREA Any fuel or oil spilled on the tiller should be wiped off promptly. Dirt, leaves and other debris must not oe left to accumulate around the cooling fins or the enc ine or on any part of the tiller. Clean the underside of tl ie tine shield after each use. The dirt washes off the tines easier if washed off immediately instead of after il dries. SPARK PLUG The spark plug should be cleaned and the gap reset every 25 hours of engine operation. Spark plug re placement is recommended at the start of each tiller soason; check engine manual for correct plug type and gap specification. BELT REPLACEMENT A CAUTION Do not use an off-the-shelf belt. Your tiller has been engineered with belts made of special material (Kevlar Tensile) for longer lils and better performance. They should not be replaced with an off-the-shelf belt. If belt replacement is required, order belt or bolts by part number from your nearest authorized dealer.
