5.14 There are seven slots 1/4"
apart in the jack assembly lower
arm. As the bottom of the jack
assembly upper arm moves past
each 1/4" slot, this represents
approximately 3/4" in blade depth
travel. Counting the number of turns
on the handle can also control the
blade depth. See Table 1, Table 2, and Figure 13.

(Positive numbers represent blade depth into concrete, negative
numbers represent clearance of blade out of concrete)
