4. Hold adjusting flats (A) and tighten nut (D). 5. Start unit and check auger. Auger must not be engaged unless auger control is depressed. 6. With engine running, fully depress auger control, the auger should engage and run normally. 7. Release auger control. Auger must stop within 5 seconds. 8. If auger does not operate properly, stop engine and recheck drive linkage adjustments. 9. If auger linkage is properly adjusted, auger drive belt tension may require adjustment. See adjusting the auger belt in this section of the manual WARNING Do not over-tighten, as this may lift the lever and cause auger drive to be engaged without depressing the Auger Control. Auger Drive Adjustment WARNING Do not over-tighten, as this may cause traction drive to engage without depressing the traction drive control (arm must remain in down position). Verify that the cables are not over-tightened: With speed selector in position 1 and traction drive control fully released, push snowthrower forward. The unit should move forward freely. If unit does not move forward freely, the cable has been over-tightened. To remedy, loosen tension on clutch cable slightly, and recheck. TRACTION DRIVE ADJUSTMENT Initial Adjustment A B C Figure 3.

If the cable is too tight the drive will be engaged without pushing the handle down. 4. Slide the cable boot (A) over the cable adjustment bracket. SPEED DRIVE ADJUSTMENT 1. Remove the gas from the gas tank. 2. Disconnect the spark plug wire. 3. Stand snowthrower on the front of the auger housing (C, Figure 6). 4. Remove the capscrews (A) on each side of the bottom panel (B). 5. Remove the bottom panel (B). 6. Position the shift speed lever in the lowest forward speed. 7. Note the position of the friction wheel (A, Figure 7). The correct distance from the right side of the friction wheel to the outside of the frmae is 4-5/16” (10.95 cm). If the friction wheel is not in the correct postition, adjust as follows. A B Figure 7. Friction Disc Measurement A. Friction Disk B.

Turn the ball joint (C, Figure 8) until it is aligned with the mounting hole in the shifter rod (E). When aligned, attach the ball joint (C) to the shifter rod (E) and tighten the jam nut (B) and locknut (D). 12. Check that the snowthrower operates in R1. If not follow procedures 1-11 and readjust as necessary. 13. Install the bottom panel (B, Figure 6) and tighten the capscrews (A).
