Servicing the Castor Arm Bushings Servicing the Castor Wheels and Bearings The castor arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move the castor fork back and forth and from side to side. If the castor spindle is loose inside the bushings, the bushings are worn and must be replaced. 1.
Removing and Installing the Cutter Blade(s) 4. To assemble the castor wheel, push the bearing into the wheel hub. When installing the bearings, press on the outer race of the bearing. The blade must be replaced if a solid object is hit, the blade is out of balance, or if the blade is bent. Always use genuine Toro replacement blades to be sure of safety and optimum performance. Never use replacement blades made by other manufacturers because they could be dangerous. 5.
Inspecting and Sharpening the Cutter Blade(s) A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death. Trying to repair a damaged blade may result in discontinued safety certification of the product. • Inspect the blade periodically for wear or damage. • Never try to straighten a blade that is bent or weld a broken or cracked blade. • Replace a worn or damaged blade.
5. Rotate the blades until the ends face forward and backward. Measure from the floor to the front tip of the cutting edge. Remember this dimension. Then rotate the same blade so that the opposite end is forward, and measure again. The difference between the dimensions must not exceed 1/8 inch (3 mm). If the dimension exceeds 1/8 inch (3 mm), replace the blade because it is bent. Make sure to measure all of the blades.
The muffler may be hot and could cause injury. Be careful while working around the muffler. 2. Start the engine. Plug the normal muffler exit with a block of wood or metal plate so that the exhaust flow will be forced out of the clean-out port. Continue to block the exit until carbon deposits cease coming out of the port. Do not stand in line with the clean-out port. Always wear safety glasses. 3. Stop the engine and replace the pipe plug.
Storage 9. Seal the air cleaner inlet and the exhaust outlet with weatherproof tape. Preparing for Seasonal Storage 10. Check the anti freeze protection and add a 50/50 solution of water and ethylene glycol anti-freeze as needed for the expected minimum temperature in your area. Traction Unit 1. Thoroughly clean the traction unit, cutting units, and the engine. 2. Check the tire pressure; refer to Checking the Tire Pressure procedure in Operation, page 19. 3.
