Chute Control
Once a season or every 25 hours of operation,
whichever is earlier, check whether the four-way chute
control™ cables have slackened. If the chute does not
rotate fully or its pitch cannot be moved up or down, the
chute control cables will have to be adjusted.

2. Adjust equally on both sides by working on both
cables. See Figure 24.
Drive Control
Refer to the Final Adjustment section of the Assembly
instructions to adjust the drive control. To check the
adjustment, proceed as follows:
1. With the snow thrower tipped forward (be certain to
drain gasoline or place plastic film under the gas
cap if the snow thrower has already been
operated), remove the frame cover underneath the
snow thrower by removing the self-tapping screws.
2. With the drive control released, there must be 1/8"
clearance between the friction wheel and the drive
plate in all positions of the shift lever.
3. With the drive control engaged, the friction wheel
must contact the drive plate.
4. If adjustment is necessary, loosen the jam nut on
the drive cable and thread the cable in or out as
necessary. Tighten the jam nut to secure the cable
when correct adjustment is reached.
5. Reassemble the frame cover and turn the unit back
to its operating position.
NOTE: If you placed plastic under the gas cap, be
certain to remove it now.
