• Disconnect spark plug wire from spark plug and ground against the engine. • Remove the two wing knobs on each side of the discharge chute and lift the discharge chute up to keep it out of the way. See Figure 8. • Remove the two hairpin clips from each clevis pin which extend through the housing and remove the pins. • Remove the flail screen from inside the housing and clean the screen by scraping or washing with water. • Reinstall the screen, making certain to reassemble the flail screen with the curve side down. • Reattach the discharge chute with the hardware previously removed and connect the bag (if equipped) to unit. Figure 8 Chipper Blades • Disconnect the spark plug wire and ground against the engine. • Remove the flail screen as instructed in the previous section. • Remove the chipper chute by removing three hex nuts and washers. • Remove the chipper chute support brace from the frame by removing the hex bolts. • Rotate the impeller assembly by hand until you locate one of the two chipper blades in the chipper chute opening. • Remove the blade using a 3/16” allen wrench on the outside of the blade and an adjustable wrench on the impeller assembly. See Figure 9. Figure 9 • Rotate the impeller to expose other blade and remove in the same manner. • Replace or sharpen blades. • When sharpening the blade, protect hands by using gloves and follow the original angle of grind. Also, Discharge Chute Hairpin Clips Wing Knobs Flat Screw Blade 11 make sure to remove an equal amount from each blade and torque to 250 - 300 in. lbs. NOTE: Make certain blades are reassembled with the sharp edge facing upward. Shredder Blade • Disconnect the spark plug wire and ground against the engine. • Lower the hopper assembly and block up the housing. • Remove the six hex lock nuts and flat washers from the weld studs on the flail housing. • Separate the hopper assembly from the impeller assembly and remove the support plate. NOTE: When reassembling the support plate, the embossed tab must face inward towards the impeller. • Remove the two wing knobs and cupped washers that secure the discharge chute and raise the chute. • Insert a 1/2” or 3/4” diameter pipe through the flail screen into the impeller to keep it from turning or remove the flail screen and insert a piece of wood into the chute opening. • Remove the two outside screws on the blade, using a 3/16” allen wrench and a 1/2” wrench. See Figure 10. • Remove the blade by removing the center bolt, lock washer, and flat washer. NOTE: Use caution when removing the blade to avoid contacting the weld studs on the housing. • When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. Figure 10 • An unbalanced blade will cause excessive vibration when rotating at high speeds and may cause damage to the unit. The blade can be tested by balancing it on a screwdriver or nail. Remove metal from the heavy side until it is balanced evenly. • When reassembling the blade, tighten center bolt to between 550 and 700 in.-lbs. and the two out bolts to between 250 and 350 in.-lbs. Storing Your Chipper Shredder • Clean the equipment thoroughly. • Wipe equipment with an oiled rag to prevent rust. • Refer to engine manual for correct engine storage instructions • Store unit in a clean, dry area. Do not store next to corrosive materials such as fertilizer. Discharge Chute Blade Flat Screw Hex Bolt Weld Stud SECTION 6: TROUBLESHOOTING Problem Cause Remedy Engine fails to start 1.
