nuts and repositioning at the desired height.  
The tension on the blade head spring can be adjusted to  
suit conditions. To stiffen the blade trip action, loosen the  
hex nut on the spring bolt and tighten the knob. The  
normal adjustment of the spring tension is for the spring  
bolt to extend 1" through the hex nut.
