Initial Adjustment
1. Lift the bellcrank arm (C, Figure 21 ) up as far as it will
go.
2. While holding the bell crank arm (C) up, adjust the
cable until all the slack is removed.
3. Back the adjustment screw (E) out 7-8 turns. Tighten
nut (D).
4. Start engine and check that the system disengages
when the control is released.
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.

After 5 hours of use, check for proper adjustment.
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 above.
