b. Slowly squeeze the attachment clutch lever
until auger shaft begins to rotate.
c. Measure the distance from the end of clutch
lever to the handlebar as shown in Figure 15.
The distance between the end of the clutch
lever and the handlebar should be 5-5/8 - 6-1/4
in. (14.3 - 15.9 cm).

range, no adjustment is necessary. If clutch
lever measurement is outside the specified
range, follow steps 2 - 7.

adjustment barrel (Figure 16).
Turn adjustment barrel up the cable to decrease
the distance between clutch lever and handlebar.

increase the distance between clutch lever and
handlebar.
3. Check attachment clutch lever measurement and
tighten the jam nut on the attachment clutch cable
adjustment barrel when the clutch lever
measurement is in range. Proceed to step 6.
If clutch cannot be adjusted to specified range with
the cable adjustment alone, perform steps 4 – 5.
