The Control Lever The Control Lever is released from Neutral by mov- ing it to the right and allowing the spring tension to pull the control lever info one ot the tour forward speeds. See Figure 2-1. NOTE Number 1 position is the slowest tine rotation speed and number 4 is the . fastest, Pulling the control lever backwards into the Reverse position reverses the direction of tine rotation. FIGURE 2-1. CONTROLS b. The Throttle Control The throttle control actuates the butterfly in the car- | buretor and may be set at stop, slow, fast or choke to control the speed of the engine. NOTE — Always check the throttle cable at the engine end for a tight connection. To stop the engine, push the throttle control all the way in. To operate the choke, pull the throttle control all the way out. See Figure 2-1. c. The Depth Bar The depth bar is used to prevent the tiller from run- ning on top of the ground instead of tilling. The deep- er you set the depth bar, the deeper you will till. Tilling depth is from O to 8-inches. See Figure 2-2. A LOCKING PIN TAILPIECE CLEVIS PIN DEPTH BAR FIGURE 2-2. DEPTH BAR 2-2. WHEEL ADJUSTMENT The wheel height can be adjusted by removing the long clevis pin on the wheel hanger and raising or lowering the setting. The higher the setting the deeper the tilling depth. See Figure 2-3. NOTE Pick a height that places the handles in b. Gasoline Remove the gas cap and fill the tank with ‘FRESH REGULAR GASOLINE.

CHECKING OIL, GASOLINE, AND GEAR CASE NOTE When packaged for shipment the ma- chine contains no oil or gasoline. Before starting the engine, oil must be added to the engine crankcase and gasoline to the tank. DO NOT mix oil with gaso- line. a. Oil With the tiller on level ground, remove the oil filler plug and pour 23% pints of good quality, SAE 30 type MS engine oil into the crankcase. Replace the oil filler plug. 2-2 FIGURE 2-4. OIL AND GASOLINE FILL ¢. Chain Case Lubricant The chain case is sealed and requires no further lubrication unless the chain case is disassembled for repair, e Step |. Step 2. Step 3. SECTION 3 OPERATING INSTRUCTIONS 3-1. STARTING THE ENGINE With the tiller set on level ground, set the control lever in NEUTRAL. Set the threttle control to CHOKE. As illustrated in figure 3-1, grasp the recoil starter handle, pull out sharply, and hold it in the out position. {Do not let cord snap back.) FIGURE 3-1. RECOIL STARTER NOTE The cord should NOT be pulled out more than about two feet. If engine fails to start, allow the cord to wind back into the housing, then pull out sharply again. Refer to Step 5. Step 4. Step 5. When the engine starts, gradually move the throttle to the FAST position. After en- gine warms up {about 2 or 3 minutes) set throttle at IDLE position. DO NOT OVERCHOKE ENGINE. Repeated cranking with throttle at CHOKE position will cause gasoline to flood the intake tube and the engine. If, after 3 or 4 attempts, the engine fails to start, place throttle in FAST position, crank the engine several times to clear out the excess fuel; and then proceed with steps 2, 3 and 4. 3-1 3-2. STOPPING THE ENGINE To stop the engine, push the throttle control all the way in to the STOP position. See Figure 2-1. When the throttle control is in the STOP position, a switch blade is activated to short-circuit the spark plug. WHENEVER THE TILLER 1S LEFT UNAT- TENDED, DISCONNECT THE SPARK PLUG LEAD AND PLACE THE THROTTLE CONTROL IN THE STOP POSITION. 3-3. STOPPING THE TINES Pull the control lever into the NEUTRAL position. The tines will not rotate. See Figure 2-1. 3-4. OPERATING THE TILLER Typical operation of the tiller is as follows: Step 1. Set the clutch control to NEUTRAL. Step 2. Start the engine as outlined in paragraph 3-1. | МОТЕ To move the tiller to the work area, keep the depth bar in the highest posi- tion. With the throttle in the SLOW posi- tion, slowly engage the control lever into the number 1 position and the tiller will walk to the work area without dig- ging into the ground. Step 3. With the clutch control in NEUTRAL, set the depth bar in one of the lower settings. NOTE When several passes must be made over a certain area, lower the depth bar each time a pass is made. Step 4. Set the throttle control to FAST. Step 5. Slowly engage the clutch control to the num- ber 1 position and the tines will begin rotat- ing. Number 4 position will give the maxi- mum tine speed. Tilling the ground for the first time should be done in the number 1 or 2 position. To pulverize the soil after it has been tilled, move the control lever to the number 3 or 4 position. NOTE The engine must be running to move the control lever into the faster speeds. NOTE A downward pressure on the handles will increase the working depth and re- duce the forward speed. An upward pressure on the handles will reduce the working depth and increase the for- ward speed. The type of soil and work- ing conditions will determine the actual setting of the depth bar and the handle pressure required. If the fines stop rotating or the belt slips, siop the engine and examine the tine area for a rock or some object that may be jamming the tines and prevent them from turning. Reversing the tiller will usually free the object. Step 6. To reverse the direction of rotation of the tines, pull the control lever into the reverse position. The control lever must be held in reverse. See Figure 2-1. 3-2 SECTION 4 MAINTENANCE 4-1, CRANKCASE OIL To ensure maximum engine performance, perform the following periodic maintenance: a. Oil Check Chetk the oil level in the crankcase before each use of the machine and after every two hours of opration. The oil level shall be over-flowing at the oil fill plug. See figure 4-1. OIL FILL PLUG FILL TO OVERFLOWING M FIGURE 4-1. OIL FILL PLUG b. Oil Change After the first two hours of operating a new engine, drain the oil (see figure 4-2) from the crankcase while engine is still hot and refill crankcase with new oil; thereafter change the oil after every 25 hours of opera- tion. This procedure ensures for minimum wear of en- gin parts and provides for virtually trouble-free oper- ation. To change the oil, proceed as follows: IM A E К \ ER on | LEVEL A OIL DRAIN PLUG FIGURE 4-2. OIL DRAIN Step 1. With the machine on level ground, place a suitable metal container under the oil drain plug, then remove the drain plug. Step 2. After the oil has been drained completely from the crankcase, replace the drain plug and tighten. Step 3. Refill crankcase with 2% pints of SAE 30 en- gine oil (A.P.I. class MS). Pour the oil slowly to eliminate airlock. 4-2. CHAIN CASE LUBRICATION The chain is permanently lubricated and requires no further lubrication unless the case is disassembled for repair. If the case is disassembled, clean the chain with kerosene, allow it to dry and work a high temperature grease, such as Lubriplate No. 310 into the chain. NOTE — A 4 oz container of Lubriplate No. 310 is available under part number 727-136. 4-3. CHAIN ADJUSTMENT No chain adjustment is necessary. 4-4, AIR FILTER Under normal operating conditions, the air cleaner, located on top of the carburetor, must be serviced after every ten hours of use. Under extremely dusty operating conditions, the air cleaner must be serviced after every hour of operation. See Figure 4-3. Step 1. Remove the wing nut and cover, Step 2. Lift off foam element from support base. Step 3. Remove metal support tube assembly (screen and two metal caps) from foam element by compressing the foam element. Step 4. a.Wash foam element in a solvent such as kerosene or liquid detergent and water to remove dirt. b. Wrap foam in cloth and squeeze dry. c. Saturate foam in engine oil, then squeeze out excess oil. NOTE LL] Use the same oil for the air cleaner that you use in the engine. d. Assemble parts and fasten to the car- buretor.

CLEANING ENGINE AND TINE AREA Any fuel or oil spilled on the filler should be wiped off promptly. Dirt, leaves and other debris must not be left to accumulate around the cooling fins or the engine or on any part of the tiller. Clean the under side of the tine shield after each use. The dirt washs off the tine easier if washed off immediately instead of after it dries. | 4-6. BELTS Check that belts are free of oil or dirt. Wipe the belts periodically with a clean rag. | я 4-2 NOTE Belt tension is automatically main- tained on the forward and reverse drive belts by idlers. No adjustment is neces- sary. 4-7. SPARK PLUG The spark plug gap should be cleaned, and reset to a 0.030-inch clearance every 25 hours of engine oper- ation [see figure 4-4). Spark plug replacement is rec- ommended at the start of each tiller season; check engine parts list for correct plug type. / 030’ FEELER ^ Y GAUGE (Де _ ; 7 / / C | SPARK PLUG FIGURE 4-4, SPARK PLUG 4-8.

BELT REMOVAL 4-3 call Step 3. Place your foot on the rear of the depth bar and apply pressure. The belts will go slack. Remove the REAR belt first and ALLOW IT TO FORM A LOOP AROUND THE VARIABLE SPEED PULLEY. Slide the center section of the variable-speed pulley towards the engine. See Figure 4-7. Remove the FORWARD belt from the engine pulley and the variable-speed pulley. Step 4. Step 5. Step 6. NOTE By following this order of belt removal, it is not necessary to remove the belt guard on the varible-speed pulley. Step 7. Remove the rear belt from the variable-speed pulley. Step 8. Reassemble with the new belts. 4-11. ADJUSTING THE CARBURETOR Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, alti- tude and load. | To Adjust Carburetor: Turn needle valve clockwise until it just closes. See Figure 4-9. CAUTION Valve may be damaged by turning it in too far. - Now open needle valve 1% turns counter-ciockwise. Close idle valve in same manner and open % to % turns. This initial adjustment will permit the engine to be started and warmed up prior to final adjustment. Final Adjustment: Turn needle valve in until engine misses (lean mix- ture) then turn it out past smooth operating point until engine runs unevenly (rich mixture). Now turn needle valve to the mid-point between rich and lean so the en- gine runs smoothly. | Hold throttle at idle position and set idle speed ad- justing screw until fast idle is obtained {1750 RPM). Hold throttle in idle position and turn idle valve in (lean) and out (rich) until engine idles smoothly. Then reset idle speed adjusting screw so that engine idles at 1750 RPM. Release throttle—engine should accel- erate without hesitation or sputtering. If engine does not accelerate properly, the carburetor should be re- adjusted to a slightly richer mixture. 4-4 IDLE SPEED ADJUSTING SCREW ICLE YALVE S NEEDLE VALVE FIGURE 4-9. CARBURETOR ADJUSTMENT 4-12. ADJUSTING CARBURETOR CHOKE Proper choke and stop switch operation is depend- ent upon proper adjustment of remote controls on the powered equipment. To Check The Operation Of The Choke: Step |. Step 2. Remove the dir cleaner. Pull the throttle control all the way out to the CHOKE position. See Figure 2-1. The choke should be closed. Step 3. The engine should shut off when the throttle control is all the way in. (STOP position.) To Adjust: | Place remote control lever on equipment in FAST (high speed) position. Loosen control casing clamp screw “‘B.” Move control casing “A” and wire until lever “D" touches choke operating link at “C.” Tighten cas- ing clamp screw “B.” Replace air cleaner. See Figure 4-10. FIGURE 4-10. CHOKE ADJUSTMENT 4-13. MAGNETO AND SPARK PLUG CHECK WARNING WHENEVER CHECKING THE MAGNETO OR THE SPARK PLUG FOR AN ELECTRI- CAL SPARK, USE INSULATED PLIERS TO HOLD THE SPARK PLUG WIRE OR THE SPARK PLUG. | a. Magneto Check Disconnect the spark plug wire from the spark plug, and place throttle control lever in CHOKE or FAST position. Using insulated pliers, hold the wire close (Va-inch distance) to engine block or cylin- der, then crank the engine several times. A spark should jump from the wire to the block or cylinder; if a spark does not occur, check the wire and the magneto. b. Spark Plug Check ñ > Step |. Step 2. Step |. Step 2. Step 3. Remove spark plug from cylinder but leave the wire connected, and set throttle at CHOKE or FAST position. Using insulated pliers, hold the metal side of the spark plug in contact with the engine block, and crank the engine several times. The spark should jump the gap between the center and side electrode in the plug. If a spark does not occur, check the elec- trode gap and repeat step 2. If no spark occurs, replace the plug. 4-5 4-14, OFF-SEASON STORAGE If the machine is to be inoperative for a period long- er than 30 days, the following precautions are recom- mended: Step 1. Working outdoors, drain all fuel from the fuel tank. Use a clean dry cloth to absorb the small amount of fuel remaining in the tank, then run the engine until all fuel in carburetor is exhausted. DO NOT DRAIN FUEL WHILE SMOKING OR IF NEAR AN OPEN FIRE. | Step 2. Drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with clean new oil, Step 3. Disconnect the spark plug wire and remove the spark plug from the cylinder. Pour about six drops of engine oil into the cylin- der, and then pull the recoil starter several times to spread the oil on the cylinder wall. Replace the spark plug, but DO NOT con- nect the wire. Step 4. Clean the engine and the entire tiller thor- oughly. Step 5. Lubricate the gear cane an indicated in par- agraph 4-2. | Step 6. Wipe tines with oiled rag to prevent rust.

Frequently asked questions
The depth bar is used to prevent the tiller from running on top of the ground instead of tilling. The deeper you set the depth bar, the deeper you will till. You can adjust the depth bar by attaching it to the tailpiece with the clevis pin and securing it with the locking pin.
The wheel height can be adjusted by removing the long clevis pin on the wheel hanger and raising or lowering the setting. The higher the setting the deeper the tilling depth.
After the first two hours of operating a new engine, drain the oil from the crankcase while the engine is still hot and refill the crankcase with new oil. Thereafter, change the oil after every 25 hours of operation. To change the oil, place a suitable metal container under the oil drain plug, remove the drain plug, and allow the oil to drain completely. Replace the drain plug, tighten, and refill the crankcase with 2 1/2 pints of SAE 30 engine oil (A.P.I. class MS).
Under normal operating conditions, the air cleaner must be serviced after every ten hours of use. Under extremely dusty operating conditions, the air cleaner must be serviced after every hour of operation. To service the air cleaner, remove the wing nut and cover, lift off the foam element, remove the metal support tube assembly, wash the foam element in a solvent, squeeze dry, saturate the foam in engine oil, squeeze out excess oil, and reassemble the parts.
Minor carburetor adjustment may be required to compensate for differences in fuel, temperature, altitude, and load. To adjust the carburetor, turn the needle valve clockwise until it just closes, then open it 1 1/2 turns counterclockwise. Close the idle valve in the same manner and open it 1/8 to 1/4 turns. This initial adjustment will permit the engine to be started and warmed up prior to final adjustment.
Proper choke and stop switch operation is dependent upon proper adjustment of remote controls on the powered equipment. To check the operation of the choke, remove the air cleaner, pull the throttle control all the way out to the CHOKE position, and ensure the choke is closed. The engine should shut off when the throttle control is all the way in (STOP position).
