WARNING: Disconnect the spark plug 
wire and ground it against the engine 
to prevent unintended starting.
WARNING: NEVER attempt to make 
any adjustments while the engine is 
running, except where specified in the 
operator’s manual.
Shave Plate 
1.  To check the adjustment of the shave plate, place the 
unit on a level surface. The wheels, shave plate and 
augers should all contact 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 unit does not self-propel, the shave plate may 
be too low and needs to be adjusted.
NOTE: On new units or units with a new shave plate 
installed, the augers may be slightly off the ground.
2.  To adjust, tip the snow thrower back so that it rests 
on the handle. Loosen the lock nuts and bolts which 
secure the shave plate to the housing. See Figure 7. 
Move the shave plate to desired position and retighten 
the nuts and bolts securely.
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. Refer to Figure 7.
1.  Remove the carriage bolts and hex lock nuts which 
attach it to the snow thrower housing.
2.  Install new shave plate, making sure the heads of the 
carriage bolts are on the inside of the housing.
3.  Adjust the shave plate according to instructions  
above. Tighten the nuts securely before operating the 
snow thrower.
NOTE: For information regarding the price and availability 
of Shave Plate Kit refer to customer support on page 2.
Control Cable 
As a result of both the control cable and the drive belt 
stretching due to wear, periodic adjustments may be 
necessary.
If the auger seems to hesitate when rotating while the 
engine maintains a constant speed, an adjustment is 
necessary. Proceed as follows:
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 8. Test the snow 
thrower to see if there is a noticeable difference.
Carburetor 
WARNING: If any adjustments need to 
be made to the engine while the engine 
is running (e.g. carburetor), keep 
clear of all moving parts. Be careful of 
muffler, engine and other surrounding 
heated surfaces.
1.  Refer to the separate engine manual, packed with 
your unit, for carburetor adjustment information.
