AugerControl
Refer to the Assembly & Set-up section for instructions on
adjusting the auger control cable.
ChuteAssembly
Refer to the Assembly & Set-up section for instructions on
adjusting the chute assembly.
Skid Shoes
Refer to the Assembly & Set-up section for instructions on
adjusting the skid shoes.
DriveControl
When the drive control is released and in the disengaged "up"
position, the cable should have very little slack. It should NOT be
tight.
NOTE: If excessive slack is present in the drive cable or if the snow
thrower's drive is disengaging intermittently during operation,
the cable may be in need of adjustment.
Check the adjustment of the d rive control as follows:
1. With the drive control released, push the snow thrower
gently forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push the
snow thrower forward. The wheels should not turn. The
unit should not roll freely.
3. With the drive control released, move the shift lever back
and forth between the R2 position and the F6 position
several times. There should be no resistance in the shift
lever.
If any of the above tests failed, the drive cable is in need of
adjustment. Proceed as follows:
1. Loosen the lower hex screw on the drive cable bracket. See
Fig. 6-5.
2.
3.
4.
Position the bracket upward to provide more slack (or
downward to increase cable tension).
Retighten the upper hex screw.
Repeat Drive Control Test to verify proper adjustment has
been achieved.
