Resumen del manual
Raising the setting of the depth bar increases the forward speed and reduces the working depth. When soil conditions are severe and several passes must be made over a certain area, the depth bar setting should be lowered each time a pass is made. Further control of tilling depth and travel speed can be obtained by variation of pressure on the handles or the throttle setting. A downward pressure on the handles will increase the working depth and reduce the forward speed. An upward pressure on the handles will reduce the working depth and increase the forward speed. The type of soil and working conditions will determine the actual setting of the depth bar and the handle pressure required. 1. Tine engagement and forward travel is achieved by moving the clutch lever to FORWARD position. Tine rotation and forward motion are stopped by moving the clutch lever to NEUTRAL position. 2. The throttle lever adjusts the engine speed. It also gives fingertip control of the carburetor and magneto stop switch. When the throttle lever is pushed completely to the right from behind the tiller, the carburetor is in START position. Pulling the lever to the left reduces the engine speed to SLOW. When the lever is pulled completely to the left from behind the tiller, the magneto stop switch grounds out the spark and stops the engine. 3. When the depth bar is positioned out of ground engagement, self-propelled transporting of the tiller is easily achieved. With no pressure on the handles and the throttle lever set for SLOW engine speed, move the clutch control handle to the FORWARD position and let the tiller gently propel itself. ADJUSTMENTS Belts—Belt slack is taken up by a spring loaded idler pulley. Because of this, belt adjustment is not required. Clutch—No adjustment of the lower clutch rod is required. This is done automatically by the spring loaded idler. NOTE: Belt and clutch adjustments can be made by moving the engine bed. Loosen the four bolts which secure it and move the engine bed forward or backward as required. Adjusting the control rod will also effect the belt and clutch adjustment. These adjustments may be necessary if handle position is changed. 3 I Handle—The position of the handle may be adjusted by removing and moving carriage bolts to the desired mounting holes. Adjustment should be made for the most convenient operating height. Wheels—Wheel positions may be varied to give further adjustment of handle height. Various wheel positions also give variations of the leverage and weight distribution over the tines. Wheels should be set to suit the local soil conditions and the operator's convenience. Tines—The standard width of cut is 26". Because of the various types of work to which the tiller may be put, variation in the tilling widths may be necessary. This can be accomplished in a number of ways. 1. Standard tine arrangement____________26" 2. Remove tines that point outward from outer tine assemblies. Tines may be interchanged with opposite sides________20" 3. Add tine extensions to standard arrangement (See page 5.)____,________40" NOTE: When adjusting tines, be sure the cutting edges enter the soil first. MAINTENANCE AND LUBRICATION Engine—Service engine in accordance with the engine manufacturer's owner's guide. NOTE: To drain oil, remove oil filler plug and tip tiller on its side. Drain oil while the engine is warm. See engine manual for filling instructions. Gear Case— Proper lubricant level should be up to the front pipe plug. Check with tiller on a level surface. Add enough to bring level up to front pipe plug hole. Use Mobilube SAE 140 Gear Oil or equivalent. Gear case should be maintained with five (5) ounces of lubricant. Belt — Access to V belt and pulley assemblies is accomplished by removing the engine and engine bed as described below. 1. Remove four cap screws which secure engine bed to mounting plate assembly. Remove engine bed with engine attached. 2. Remove hex screw, lockwasher and flatwasher in 4W pulley. Remove pulley and "V" belt. The belt clip on idler must be loosened to remove belt, mark correct location of belt clip in relation to idler before loosening. This can be done by scribing the belt clip and the end of the weld bolt in idler with a file. It is most important that this clip be reassembled in the right position. 3. Position new belt on 4W pulley and reinstall on gear case shaft. Pulley must be mounted in position so that it will line up with engine pulley when assembly is completed. The correct position is that point at which the center of the pulley is 1 %" above the mounting plate assembly. Tighten hex screw, lockwasher and flat washer securely. 4. Line up the belt clip in original position and tighten securely. Make sure belt is inside belt guards. While holding the belt taut (grasp at extreme rear position), move clutch belt lever to FORWARD and NEUTRAL position. If belt clip touches belt with I ever in either position, readjust position of clip. ...
