Before attempting any adjustment, be sure that the engine 

is shut off. The key, spark plugs, battery cable are 

removed. And the engine cool to touch! 

 

Teeth should be positioned in the pockets & tightened to  
100 - 110 ft/lbs. torque 

 

Teeth should be set using a tooth gauge so all teeth will be projecting the 
same amount. 

 

Teeth should be set as follows: 

 

 

STR 

LH

Caution:

 Never use the machine with missing teeth or badly worn teeth, 

this will cause the cutter wheel to be out of balance & cause wear on 
bearings & shaft. 

 

The pockets are reversible, when turning, position them in the exact 
location- this will ensure the cutter wheel remains in balance. 

 

Teeth should be kept sharp. 
 

Installation of Teeth 

 

When installing teeth on the cutter wheel, be sure the teeth are all 
extended to an equal length beyond the wheel. A tooth gauge is provided 
for this.
