Readjust clutch cable if necessary by increasing ten-
sion on cable. A small amount of bellcrank arm
movement is permissible if unit passes operating
checks described in the Caution at left.
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.
