Control Cable  
Adjustments  
As a result of both the control cable and the auger drive belt  
stretching due to wear, periodic adjustments may be necessary. If  
the auger seems to hesitate when rotating, proceed as follows:  
WARNING! Before servicing, repairing or  
inspecting the snow thrower, disengage the auger  
control. Stop the engine and remove the key to  
prevent unintended starting.  
The upper hole in the control handle provides for an adjustment in  
cable tension. To adjust, disconnect the end of control cable from  
the bottom hole in the control handle and reinsert it in the upper  
hole. Insert the cable from the outside as shown in Figure 6-2.  
Shave Plate  
To check the adjustment of the shave plate, place the snow  
thrower on a level surface. The wheels, shave plate and auger  
should all contact the level surface. Note that if the shave plate is  
adjusted too high, snow may blow under the housing. If the shave  
plate wears out excessively, or the snow thrower does not self-  
propel, the shave plate may be too low and needs to be adjusted.  
Auger Control Handle  
NOTE: On new snow throwers or machines with a new shave plate  
installed, the auger may be slightly off the ground.  
To adjust the shave plate proceed as follows:  
1.  
Run the snow thrower until the fuel tank is empty.  
2.  
Pull the recoil starter handle until resistance is felt. Then tip  
the snow thrower back until it rests on the handles.  
3.

Replacing Auger Paddles  
Replacing Shave Plate  
The shave plate is attached to the bottom of the auger housing  
and is subject to wear. It should be checked periodically. There  
are two wearing edges and the shave plate can be reversed.  
The snow thrower auger’s rubber paddles are subject to wear  
and should be replaced if any signs of excessive wear are present.  
CAUTION: Do NOT allow the auger’s rubber  
paddles to wear to the point where portions of the  
metal auger itself can come in contact with the  
pavement. Doing so can result in serious damage to  
your snow thrower.  
1.  
Run the snow thrower until the fuel tank is empty.  
2.  
Pull the recoil starter handle until resistance is felt. Then tip  
the snow thrower back until it rests on the handles.  
3.  
Remove the four carriage screws and flange lock nuts which  
attach it to the snow thrower housing. See Figure 7-5.  
To change the rubber paddles, proceed as follows:  
1.  
Remove the existing rubber paddles by unthreading the hex  
washer screws which secure them to the auger. See Figure 7-4.

so that the auger still attached can be used as an example for  
positioning and re-installing the new auger.  
Adjust the shave plate as instructed in the Maintenance &  
Adjustments section.  
Tighten securely once adjusted.  
2.  
Secure the replacement rubber paddles to the auger using
