BELT COVER FRAME SCREWS FIG. 22 FIG. 21 17 SERVICE AND ADJUSTMENTS TO REPLACE BELTS (See Fig. 23) The auger and traction drive belts are not adjustable. If the belts are damaged or begin to slip from wear, they should be replaced. It is recommended that the belt(s) be replaced by a qualifi ed service center. NOTE: It is recommended that both the auger and traction drive belt be replaced at the same time. The V-belts on your snow thrower are of special con struc tion and should be replaced by original equipment man u fac tur er (OEM) belts avail able from your nearest dealer. Using other than OEM belts can cause personal injury or damage to the snow thrower. WARNING: Belt replacement requires separation of the snow thrower. While separating the auger housing from the frame assembly, it is important that an assistant stand in the operating po si tion and hold the snow thrower han dles. Serious personal injury and/or damage to the unit could occur if the snow thrower should fall during the belt chang ing process. HINT: Insert a 3/8" drive ratchet (in the “ON” position) into the square hole in idler arm and rotate ratchet clockwise to relieve tension. 8. With tension relieved on idler, install new traction drive belt around pulleys and inside belt keepers. 9. Place auger belt around and inside the groove of auger pulley only. 10. While your assistant slowly raises handles to rejoin the auger hous ing and frame assembly, pull up on the auger belt and squeeze sides together above pulley so belt is fully seated in groove of pulley. 11. Bring snow thrower completely together and check carefully for proper routing of belts. If auger belt has become dislodged from the pulley (by catching the idler arm bracket while bringing snow thrower together), separate the snow thrower and re peat step 10. Belt must be fully seated in pulley groove when bring ing the snow thrower together. 12. Install the two (2) hex bolts and lock washers and tighten securely. 13.
