2. Loosen the jam nut (B, Figure 9). 3. Turn the adjustment nut (A) to lengthen or shorten the cable. The cable should be tightened just until all slack is removed from the lever, however it must not engage the Easy Turn™ release without depressing the control lever. 4. Tighten the jam nut. A B Figure 9. Easy Turn™ Cable Adjustment A. Adjustment Nut B. Jam Nut Large Frame Snowthrowers Scraper Bar & Skid Shoe Adjustment On smooth surfaces such as concrete or asphalt, the scraper bar should scrape the surface. On surfaces such as gravel, the scraper bar should be high enough so that it will not pick up gravel or debris. The height of the scraper bar is controlled by raising or lowering the Skid Shoes (See Figure 10). 1. To raise the scraper bar height, rest the scraper bar on a strip of wood equal in thickness to the desired height. 2. Make sure the scraper bar is parallel to the ground surface. 3. Loosen the skid shoe nuts and let the skid shoes drop to the surface. 4. Tighten the nuts, making sure the Skid Shoes are adjusted equally and are parallel to the surface. 5. To lower the height of the scraper bar, raise the Skid Shoes. 6. If the scraper bar becomes worn, it can be adjusted by loosening the nuts and bolts attaching it to the snowthrower, making the adjustment, and tightening the hardware. It may also be replaced by removing the mounting nuts and bolts attaching it to the snowthrower. A B C Figure 10. Skid Shoe Adjustment A. Scraper Bar B. Skid Shoe C.

If it is correct, then check the condition of the auger drive belt. If it is damaged or loose,replace it (see Belt Replacement in this section of the manual). 1. Disconnect spark plug wire. 2. Loosen screw (B, Figure 11) from belt cover (A). Remove belt cover (A). 3. Loosen nut (D, Figure 12) on auger idler pulley (B) and move auger idler pulley towards belt about 1/8 inch (3mm). 4. Tighten nut (D). 5. Engage auger drive clutch. Check tension on belt (opposite idler pulley). Belt should deflect about 1/2 inch (12.5 mm) with moderate pressure see Figure 12). You may have to move the idler pulley more than once to obtain the correct tension. 6. Reinstall belt cover (A, Figure 11) securing with screws (B). 7. Whenever belts are adjusted or replaced, the auger drive or traction drive controls will need to be adjusted. (see Auger Drive or Traction Drive Adjustment in this section of the manual). 8. Attach the spark plug wire. 9. Auger must stop within 5 seconds. Traction Drive Belt The traction drive belt has constant spring pressure and does not require an adjustment. If the traction drive belt is slipping,replace the belt. See Belt Replacement. Note: After adjustments are complete, make sure the drive disengages when released. AB B Figure 11. Belt Cover A.

Auger Belt TP 300-4458-00-LW-SN 18 07/2007 Large Frame Snowthrowers Belt Replacement Auger Drive Belt The drive belts are of special construction and must be replaced with original factory replacement belts available from your nearest authorized service center. Some steps require the assistance of a second person. If the auger drive belt is damaged, the snow thrower will not discharge snow. Replace the damaged belt as follows. 1. Disconnect the spark plug wire. 2. Remove the capscrews (A, Figure 13) on each side of the bottom panel (B). 3. Remove the bottom panel (B). C A A B Figure 13. Bottom Cover A. Capscrews B.

Pull the belt guide away from the auger drive pulley (C). 6. Pull the auger idler pulley (K) away from the auger drive belt (D) and slip the belt off of the idler. 7. Remove the auger drive belt (D) from the engine pulley. To remove the auger drive belt (D), the auger drive pulley (C) may have to be partially rotated. 8. Index or point the spout to the center of the machine so that the rotator control is in the center of the dash panel. I J H G A E D C B A F L K Figure 14. Pulleys and Belts A. Traction Drive Belt B.
