Release auger control. Auger must stop within 5 seconds. Traction Drive Linkage Adjustment 1. With the drive lever released there should be no slack in the cable when moved slightly from side to side, but bellcrank arm (C, Figure 20) remains in fully down position. 2. To adjust tension on the cable loosen adjustment hex nut (D) by holding the adjusting flats (A). Turn the adjustment screw. The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the traction drive clutch cable spring 3. Engage the drive lever to check the adjustment. When correct, tighten hex nut securely. The unit should able to be pushed forward and back freely. Run-In Adjustment 1. After 5 hours of use, check for proper adjustment. Readjust clutch cable if necessary by increasing tension on cable.

Spring Hook E. Adjustment Screw C. Bellcrank Arm D E B C WARNING Do not over-tighten, as this may cause traction drive to engage without depressing the traction drive control (bellcrank 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. Intermediate Frame Snowthrowers Speed Selector Adjustment 1.
