Move lever as illustrated. Figure I I Figure 12 CARBURETOR ADJUSTMENTS (See Fig. 12) Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude and load. 1. To make the initial adjustment: close needle vaive (turn clockwise), then open 1-1/2 turns (counterclockwise). This initial adjustment will permit the engine to be started and warmed up before making final adjustment. 2. Final adjustment is made with engine running at normal operating speed (approximately 3000 RPM without load.) Close the needle valve (turn clockwise) until engine starts to lose speed (lean mixture). 3. Then siowly open needle valve (turn counterclockwise) past the point of smoothest operation, untii engine just begins to run unevenly. This mixture should be rich enough for best performance under load. 4. Hold throttle in idling position. Turn idle speed adjusting screw until fast idle is obtained. {1750 RPM). Test the engine under full load. If engine tends to stall or die out, it usually indicates that the mixture is slightly lean and it may be necessary to open the needle valve slightly to provide a richer mixture. This richer mixture may cause a slight unevenness in idling. TINE ADJUSTMENT The standard tilling width is 28" with both inner and outer tine assemblies mounted. Tilling width is 14" with outer assemblies removed. To remove outer tine assemblies from inner tine assemblies, remove pin clip from clevis pin. Slide clevis pin out and remove outer tine assembly. Extension tines provide a tilling width of up to 38".

Minor adjustments, if needed, can be made by using the links on the clutch cable chain only. However, the friction type clutch may need further adjustment as the "V" belt stretches. Adjust as follows: 1. Remove belt guard. 2. Loosen 4 engine mount bolts. Slide engine forward or backwards as required. 3. Unhook clutch cable from load spring. 4. Push upward on idler pulley to take all slack from the drive belt. Distance between the inside of belt at the idler pulley should be between 2-7/8 and 3-1/8 of an inch. 5. Re-tighten engine mounting bolts. 6. Remove ail the slack from clutch cable and hook spring in proper chain link. 7. Check your adjustment by starting the tiller and holding the tines off the ground. If the tines turn without any hand pressure on the clutch lever, the adjustment is too tight. Unhook the clutch load f spring and hook into next chain link to lengthen clutch cable. If the cable spring on the clutch handle doesn't stretch when you hold the clutch handle all the way in, the adjustment is too loose. Unhook spring end from chain and hook next link to shorten clutch cable. Figure I3 MAINTENANCE PERIODICAL CHECK 1. Regularly check all bolts and nuts for tightness. Bolts marked "A" must be torqued to 21 ft. lbs. See Figure 10. 2. If the belt begins to bottom out on the engine pulley, then replacement of the pulley is needed. This is noticeable by the pulley "V"’ bottom becoming shiny. ENGINE OIL (See Fig. 6) 1. Check the oil level before starting the engine and after every five hours of operation. Before removing the filter plug, clean the area around it to prevent dirt from entering the oil fill hole. The engine should be in a level position when checking the oil. Remove the filler plug and fill the crankcase with oil, Use a high quality detergent oil classified "For service SC, SD, SE, or MS." In temperatures above 40 degrees F, use SAE-30. If not available, use SAE 10W-30 or SAE 10W-40. Add oil as necessary to keep oil level as indicated in Figure 6. Detergent oils keep the engine cleaner and retard the formation of gum and varnish deposits. Nothing should be added to the recommended oil. 2. Change the oil after the first five hours of operation and every 25 hours thereafter. Always change oil while the engine is warm. Oil may be drained through the oil drain ...
