Resumen del manual
Failure to tighten or replace fasteners can cause poor performance, equipment damage or oil leakage. See your Parts Catalog for complete fastener descriptions. Most hardware on your tiller is visible. Pay particular attention to hardware shown in Photos 5-1,5-2, 5-3, and Figure 5-3A. 1. Check the transmission pulley mounting bolt (Photo 5-1). If the washer behind the bolt head is loose, the bolt needs tightening. To do this, first insert a punch or thick screwdriver into the hole next to the bolt and wedge the tool against the side of the motor mount casting. This “freezes” the pulley while you tighten the bolt. 2. Check jam nut on left side of neutral plunger assembly (Photo 5-2). If loose, immobilize bolt head with one wrench and use another wrench to tighten the nut. 3. Check the three rear bearing cap screws under the depth regulator mounting bracket (“A”, Photo 5-3). If any is loose, it can cause an oil leak or drive shaft end play. 4. Check the five bolts securing the tiller housing cover to the left side of the transmission (“B” in Photo 5-3). Gear oil can leak from a loose housing cover. To reach the bolts, remove the left side tine holder. See “Bolo Tine Maintenance” in this Section for tine holder removal directions. 5. Check both swing-bolts (“C”, Photo 5-3) that connect the power unit transmission to the tine attachment. Both bolts should be checked every 2-1/2 hours of operation. If loose, wear can occur on the locating pin on the power unit, and cause enlargement of the locating hole in the tine attachment. Using a torque wrench, tighten these bolts to 70-to-80 ft.-lbs. 6. Check the locknut that fastens the shifting linkage to the eccentric shifting lever (“D”, Photo 5-3). Do not tighten the locknut against the eccentric lever. It should be very close to, but not touching the lever. 7. Check the four bolts and nuts securing left and right tine holders to the tine shaft (Figure 5-3A). IMPORTANT- Give screws or bolts that go into the transmission housing a coating of nonhardening gasket sealant to prevent gear oil from leaking. Figure 5-3A: Tine holder hardware must be tight. Photo 5-1: Check bolt on transmission pulley. Photo 5-2: Check jam nut on plunger assembly. Photo 5-3: Gently tilt tiller forward to check fasteners. Maintenance/Repairs TILLER LUBRICATION WARNING To help avoid personal injury, stop the engine, remove the electric start key, disconnect the spark plug wire and move the wire away from the spark plug, and let the engine and muffler cool before inspecting or lubricating the tiller. Proper lubrication of the tiller’s mechanical parts is an essential part of good maintenance. Lubrication should be done after every ten (10) hours of operation. Use ordinary motor oil (#30 weight or lighter) where oil is specified. Use a quality grease with a metal lubricant where grease is recommended (regular grease is acceptable). Do not overlubricate. If there is a build-up of dirt, remove the build-up and reapply oil or grease. IMPORTANT - Do not allow oil or grease to contact the pulleys, drive belt or reverse disc. This can cause the belt or disc to slip on the pulleys. Lubricate the numbered areas in Photos 5-4 and 5-5, as follows: 1. Oil the wheel shaft between the wheel hubs and the transmission housing (Photo 5-4). 2. Oil all pivoting and connecting points on the Wheels/Tines/PTO Drive Lever and the Wheel Speed Lever (Photo 5-4). If Wheel Speed Lever has a grease fitting on pivot assembly, apply 2-to-3 strokes of multi-purpose grease at beginning and end of tilling season. 3. Grease the face of the belt adjustment block (Photo 5-4). 4. Oil the Depth Regulator Lever, including the spring in the mounting bracket (Photo 5-4). 5. Oil the full length of the throttle cable casing (Photo 5-4). 6. Oil threads on Handlebar Height Adjustment Lever (Photo 5-4). 7. Grease left- and right-side engine mounting bars at the top, the middle, and bottom (Photo 5-4). \ TRANSMISSION GEAR OIL I MAINTENANCE i A WARNING To help avoid personal injury, stop the engine, remove the | electric start key, disconnect I the spark plug wire and move j it away from the spark plug, I and let the engine and muffler cool before inspecting or 3 servicing the tiller. 1 A. Checking for Oil Leaks S At 25-hour operation intervals, | check the tiller for oil leaks.

You should tighten j all bolts immediately, and replace 1 any worn seals or gaskets. j It may be impossible to deter- | mine how much oil has been lost, | so check the oil levels in the PTO j transmission and the tine attach- ? ment before using the tiller again.
