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.
