Resumen del manual
Your SNAPPER Dealer has a complete listing of all components. For engine parts, look for the engine manufacturer’s dealers under the heading ENGINES - gasoline in the yellow pages of your telephone directory. SNAPPER Dealers are listed under LAWN MOWERS. STANDING TILLER ON END CAUTION: If the fuel tank is over one-half full when the tiller is placed on end, gasoline may leak from the carburetor vent hole and drip down the outside of the engine causing a potential fire hazard! Gasoline may also leak unnoticed into the engine cylinder causing engine damage. Take the necessary steps to prevent fuel leakage before standing tiller on end. Any draining or transfer of fuel must be done outside with the engine cool and away from ignition sources. If the tiller is stored on end for any length of time, check for oil leakage. WARNING! NEVER STAND THE TILLER ON END WITH THE ENGINE RUNNING! Stop the engine and disconnect the spark plug wire to prevent accidental starting before standing on end. SERVICE NOTE: Since a tiller normally operates under extremely dusty or dirty conditions, the air cleaner, engine oil and cooling fins must be serviced as specified in the engine manual at frequent intervals. The tiller itself should be serviced as follows: ENGINE SERVICE: Refer to the engine owner’s manual for details. Engine oil is drained by removing front filler plug and standing tiller on end. TILLER LUBRICATION CHAIN CASE: Check the level of the grease in the chain case at the beginning of each tilling season. Check by removing the plastic plug located beside the axle shaft on the lower left hand side. The level should be up to the edge of the opening. To add grease, remove the filler plug located just forward of the pulley shaft on the R.H. side. Add SNAPPER 0 grease as needed to bring level up to bottom edge of the check/*l| plug opening. The total capacity of the case is about 1 U.S. Standard quart - do not exceed this amount. Reinstall plugs after checking. See Figure 9. 6 SERVICE BELT ADJUSTMENT- REPLACEMENT BELT TENSION ADJUSTMENT: To chpck, remove L.H. wheel and drive belt guard. Measure the length of the IDLER PULLEY SPRING at the end of the control cable. Move the WHEEL & TINE CONTROL up to the handle bar and measure the extended length of the spring. When properly adjusted, the spring should extend 1/4" to 1/2" when WHEEL & TINE CONTROL is engaged. If adjustment is required, loosen and reposition the jam-nuts on the threaded ends of the cable conduits. To increase spring extension, turn the jam-nuts closer to the cable fittings. See Figure 11. TRANSMISSION CHECK PLUG (on Left side) FIGURE 9 O TILLER TINES TINE SERVICE: The SNAPPER IRT-4001 SERIES TILLER has R.H. and L.H. tines. Check both tines periodically for loose or missing fasteners. Replace tine assembly when blades are badly worn or damaged. Use SNAPPER #4-9735 R.H. and #4-9734 L.H. tines with #1-5676 shear bolts and #9-0222 locknuts for replacement purposes. The tines are bolted securely to the tine shaft with a special shear bolt (SNAPPER #1-5676) and locknut (#9-0222) on each side. Keep spares on hand in case a bolt shears off or becomes lost while tilling. See Figure 10. NOTE: Do not over-tighten shear bolts as this will cause failure. Tighten 5 to 8 foot pounds of torque maximum ! BELT ADJUSTMENT TEST: start engine and pull WHEEL & TINE CONTROL to handle bar then release ana observe tines and wheel drive which should stop. If tines or wheels continue after WHEEL & TINE CONTROL is released, the clutch spring extension is too great. Readjust using the fore going procedure. BELT REPLACEMENT 1. Remove the left hand wheel. 2. Remove two 1/2” screws and nuts from guard. 3. Remove guard. Remove old belt and replace with new belt. Belt must be OVER TOP of IDLER and within BELT GUIDE for proper installation. See Figure 12. DRIVE PULLEY SHIFT LEVER. BELT OVER TOP OF IDLER ' T-REMOVE L.H. / WHEEL & — BELT GUARD FIGURE 12 7 's a snap with NAPPER ACCESSORIES Your tiller can be converted to become an even more versatile garden tool with the addition of the optional accessory kits listed below. Contact your SNAPPER dealer for complete information on these and other kits which may be made available later for your Model IRT4 tiller. HILLER/FURROWER KIT—#6-0731 CULTIVATOR SHIELD KIT-#6-0865 OFF-SEASON STORAGE Thoroughly clean all external surfaces and tines before storing the Tiller. The Tiller may be stored on end, however, the following steps must be taken. 1. Drain gasoline from fuel system and drain the engine crankcase oil (refer to engine manual for details). 2. After standing the Tiller on end, check the plugs in the chain case for leakage. After extended period, some grease may seep thru upper bearing races. 3. At the start of the new season, replenish engine crankcase oil and add gasoline to the fuel tank after returning the Tiller to its wheels. 4. Before starting, move the ENGINE CONTROL to STOP and pull rop...
