 Setup 

 

 
 

 

Secure Clutch Cable to Handle

Locate keeper on lower left side of handle.  Remove the 
10-24 Screw and attach Clutch Cable using the tab on 
cable housing.  
 
Be sure Clutch Cable is on the outside of Throttle and 
Brake Cables, then secure all cables (Except Clutch) to 
handle with nylon ties provided with Throttle Cable down 
left side and Brake Cable under handle. 

 

 

Bottom View for Reference 

The two bolts next to the engine pulley are belt 
guides, that create a loop around the pulley 
keeping the drive belt from engaging while the 
engine is running and clutch is disengaged.   
 
There are three pulleys on the bottom of the 
unit: The engine drive pulley, the large 
transmission and the small clutch pulley on the 
clutch arm.  

These pulleys need to be line

 

with each other.

  The bolt on the left side of 

Clutch Arm will need to be adjusted after the 
first couple hours of use. If the Clutch Arm 
drops down out of alignment, it will run on the 
rim of the idler pulley and spin the drive belt 
off the unit.
