If the full range of speeds (forward and reverse) cannot 
be achieved, refer to Figure 5-1 and adjust the shift rod 
as follows:
1.  Looking underneath the handle panel, note which 

of the three holes in the shift lever the ferrule is 
inserted into. Also note the direction of insertion. 
Then remove the internal cotter pin and flat washer 
from the ferrule and withdraw the ferrule from the 
shift lever. See Figure 5-1.

2.  Place shift lever in sixth (6) position or fastest 

forward speed.

3.  Push shift rod and shift arm assembly down sharply, 

as far as it will go to put the drive into the fastest 
forward position.

4.  As necessary, rotate the ferrule up or down the shift 

rod until the ferrule lines up with the hole from which 
it was earlier removed. See Figure 5-1.

5.  From the direction noted earlier, insert the ferrule 

into the proper hole. 

6.  Reinstall the washer and the internal cotter pin.

Refer to the Final Adjustment section of the Set-Up 
instructions to adjust the drive control. To further check 
the adjustment, proceed as follows:
1.  Tip the snow thrower forward, allowing it to rest on 

the auger housing.

2.  Remove the frame cover underneath the snow 

thrower by removing 

the

 self-tapping screws. See 

Figure 5-2.

3.  With the wheel drive control released, check if there 

is clearance between friction wheel and drive plate in 
all positions of the shift lever. See Figure 5-3.

4.  With the drive control lever engaged, check if the 

friction wheel solidly contacts the drive plate. See 
Figure 5-3. If not, adjust as follows:
a.  Loosen the jam nut on the drive cable and thread 

the cable in or out as necessary.

b.  Retighten the jam nut to secure the cable when 

correct adjustment is reached. 

5.  Reassemble the frame cover.
