The belt comes adjusted from the factory.  If 
adjustment is needed:

source.

3.  Set the belt tension by lightly pressing down on 

the motor and tightening the hex cap bolts (A, 
Fig. 19). 

Note: The weight of the motor should put enough 
tension on the belt. You just want to push down 
lightly to take up any slack.
