Any power equipment can cause injury if operated improperly or if the user does not understand how to operate the equipment. Read this owner's manual carefully and know how to operate your snow thrower and how to stop the unit and disengage the controls quickly. Never allow adults to operate the equipment without proper instruction. [. . . ] Hook the assembly's notched arms onto the two shoulder bolts you assembled to the inside of the tractor frame. Hanger brackets using two pivot lock pins (GG) and 1/8" hairpin cotters (EE). Assemble the short "V" belt onto the engine pulley and then onto the large pulley on top of the clutch/idler assembly. The belt must be placed to the inside of the engine pulley keeper, the idler pulley and the keeper bolt located beside the large pulley. IMPORTANT: Do Not assemble the "V" belt around the outside of the engine pulley keeper or the keeper bolt. Attach the two suspension arms to the rear of the clutch/idler assembly using two 5/16" x 3/4" hex bolts (C), 5/16" washer (Q) and 5/16" nylock nuts (Y) for each arm. Place the arms on the outside of the frame with the notches to the rear. Insert a tensioning chain through the hole shown and attach the end link to the spring on the lower idler arm. Hook the spring from the parts bag through the end of the tensioning chain. Hook the other end of the spring onto the bottom of the bolt and nut which secure the idler pulley to the upper idler arm. Hold the bolt head and assemble a 3/8" hex lock nut (Z) onto the bolt, leaving enough space for the spring to pivot freely between the two nuts. Pace the extra tensioning chain (JJ) through the left front hole in the clutch/idler assembly and then turn the assembly upside down. Use the table below to select the correct drive belt for your type tractor. Set aside the belt that is not for your tractor to avoid accidentally using it. Install the drive belt down between the hex bolt and the flat idler pulley with the flat side of the belt against the pulley. Loop the belt around the large v-pulley, placing it between the v-pulley and the hex bolt next to the pulley. Assemble the drive belt onto the engine pulley and then onto the large pulley on top of the clutch/idler assembly. The belt must be placed to the inside of the idler pulley and the keeper bolt located beside the large pulley. Place tension on the belt by pulling the left side tensioning chain out as far as the 3/32" hairpin cotter (FF) will allow. Secure the chain in this position by inserting a 1/8" hairpin cotter (EE) through the chain. IMPORTANT: Do Not assemble the "V" belt around the outside of the engine pulley keeper or the keeper bolt. Using the wrong length belt may cause premature bearing or belt failure. [. . . ] Adjust both skid shoes to the same height to keep the housing and the scraper plate level. The spiral augers are secured to the auger shaft with two shear bolts and nylock nuts. If you hit a foreign object or if ice jams the augers, the snow thrower is designed so that the bolts will shear. Two replacement shear bolts and nylock nuts have been provided with the snow thrower.
