21 and 22) Replace V-belts if they have stretched considerably or if they show cracks or frayed edges. There are two (2) V-belts - forward (inside) and reverse (outside). Beit guard must be removed to service belts. See ‘TO REMOVE BELT GUARD” in this section of manual. NOTE: Observe carefully routing of both belts and location of all belt guides before removing belts. BELT REMOVAL • Remove reverse idler pulley from idler arm. 9 Remove reverse (outside) V-belt. 8 Remove forward (inside) V-belt from transmission pulley first and then from engine pulley. BELT REPLACEMENT « Install new forward (inside) V-belt to engine pulley first then to transmission pulley. Be sure belt is positioned on inside groove of both pulleys, inside all belt guides and rests on idler pulley. • Before installing reverse (outside) V-belt, turn belt “inside out”. Twist so wide, flat surface of belt is to inside. • Wrap V-belt around reverse idler pulley and reassemble idler to idler arm. Tighten securely. Be sure belt is between reverse idler pulley and idler arm pin. • Install beltto outside groove of transmission pulley. Be sure belt is inside all belt guides and rests on outside groove of engine pulley. CHECK TINE OPERATION • See “TINE OPERATION CHECK” in this section of manual. 14 REPLACE BELT GUARD SERVICE AND ADJUSTMENTS ENGINE TO ADJUST CARBURETOR The carburetor has a high speed fixed jet and has been preset at the factory and adjustment should not be necessary. However, minor adjustments may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, see engine manual. High speed stop is factory adjusted. Do not adjust or damage may result. IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE SPEED. OVERSPEEDING THE ENGINE ABOVE THE FACTORY HIGH SPEED SETTING CAN BE DANGEROUS. IF YOU THINK THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING, CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/ DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT AND EXPERIENCE TO MAKE ANY NECESSARY ADJUSTMENTS. FIG. 21 15 FORWARD MOTION (INSIDE) V-BELT REVERSE (OUTSIDE) V-BELT FRONT VIEW REFERENCE 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. TILLER • Clean entire tiller (See “CLEANING” in the Customer Responsibilities section of this manual). • Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). • Lubricate as shown in the Customer Responsibilities section of this manual. • Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. • Touch up all rusted or chipped paint surfaces; sand lightly before painting. ENGINE FUEL SYSTEM IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS THE CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT ALCOHOL BLENDED FUELS (CALLED GASOHOL OR USING ETHANOL OR METHANOL) CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION AND FORMATION OF ACIDS DURING STORAGE. ACIDIC GAS CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN STORAGE. • Drain the fuel tank. « Start the engine and let it run until the fuel lines and carburetor are empty. • Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean oil. (See “ENGINE” in the Customer Responsibilities section of this manual). CYLINDER(S) • Remove spark plug. • Pour 1 ounce (29 ml) of oil through spark plug hole into cylinder. • Pull starter handle slowly several times to distribute oil. » Replace with new spark plug. OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • If possible, store your unit indoors and cover it to give protection from dust and dirt. • Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust. IMPORTANT: NEVER COVER TILLER WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM. A 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 stor...
