Maintenance & Adjustments 6 WARNING! Disconnect the spark plug wire and ground it against the engine before performing any maintenance or repairs. Maintenance Engine Refer to the separate Engine Operator's Manual for engine maintenance instructions. Tires Recommended operating tire pressure is approximately 20 p.s.i. on 16 inch tires. (Check the sidewall of the tire for the manufacturer's recommended pressure). Maximum tire pressure under any circumstances is 30 p.s.i. Equal tire pressure should be maintained on both tires. WARNING! Excessive pressure (over 30 p.s.i.) when seating beads may cause the tire/rim assembly to burst with force sufficient to cause serious injury. Tines Clean the underside of the tine shield after each use. The dirt washes off the tines easier if rinsed off immediately instead of after it dries. Always towel dry the tiller afterwards and apply a light coat of oil or silicone to prevent rusting or water damage. NOTE: Never use a "pressure washer" to clean your tiller. Water can penetrate tight areas of the tiller and its chain case and cause serious damage to the tiller. Lubrication Transmission The transmission is pre-lubricated and sealed at the factory. It requires no checking unless the transmission is disassembled. To fill with grease, lay the right half of the transmission on its side, add 22 ounces of Benalene 920 grease, and assemble the left half to it. This grease can be obtained at your nearest authorized dealer by ordering part number 737-0300 or calling the Customer Support number on page 2. Clutch Handle Lubricate the pivot point on the clutch handle and the cable at least once a season with light oil. The control must operate freely in both directions. Pivot Points Lubricate all the pivot points and linkages at least once a season with light oil. Tine Shafts Remove the tine assemblies and lubricate the tine shafts at least once a season. Wheel Shafts Remove the wheel assemblies and lubricate the axle shafts at least once a season. 14 Adjustments WARNING! Never attempt to make any adjustments while the engine is running, except where specified in the Operator's Manual. Engine Adjustment Refer to the separate Engine Operator's Manual for engine adjustment instructions. Clutch Cable Refer to the Assembly & Set-Up section of this manual for instructions on adjusting the clutch cable. Idler Pulley Rod After the belt tension has been adjusted, if the belt is excessively stretched, you may need to adjust the idler pulley rod. This can be checked easily. With the engine off and the clutch control bail disengaged, shift the gear selection handle to each forward mode. If the indicator bracket touches the idler pulley rod with the clutch control bail disengaged, then an adjustment is necessary. 1. Disconnect and ground the spark plug wire against the engine. 2. Remove the belt cover as described under Belt Replacement in the Service section. 3. Remove the cotter pin and spring washer from the idler pulley rod. See Figure 6-1. Rubber Washer Control Rod Indicator Bracket Cotter Pin Idler Puller Rod Figure 6-1 4. Move the idler pulley rod to the lower hole in the idler bracket. 5.
